To all whom it may concern: I

Be it lmown that I, Jnssn G. BATES, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a- Stapling Machine; and I do hereby declarethat the following is' a full; clear, andiexact description of the same, reference being bad to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of thlsspecification.

This invention relates to an improved stapling machine adapted to be manually o erated-to cause staples to be automatically discharged one at a time and forced into engagement with one ofthe walls or sides of a wooden box for the purpose of sup lyinga means whereby address cards or la els ofany descriptionmay be easily securedin place on a wooden container.

It is an object of this invention to provide a stapler adapted to be manuallyoperated to rst cause a staple to be cut from a-staple strip and then cause the prongs of the severed staple to be forced through the card and into the material of the container for the purpose of holding the card securely in place, g g I t is also an object of this invention to provide a stapler which when manually op erated causes a. staple to be cut from a maram device to first automatically out OK a controlled handle for the vterial strip and then rammed into the material on which the stapler is a plied.

It is a further object of. this invention to provide a stapler for fastening address cards on wooden shipping crates and the like, said stapler havin a spring controlled handle mechanism w ich when operated causes a staple from a staple strip and'then ram the prongs of said cut oil staple through the material which is to be secured in place without bendin said prongs.

It is a still urther object of this invention to provide a stapler wherein-a'stri of integral y connected staples is adapte to be automatically fed'beneath the ram. each time the machine is operated by a spring and ram the TIIIPOSG o1' per-- *the innermost ough the 'material and into a support to hold the ma-- terial secured in place thereon.

It is an important object of this inven- Mon to provide an improved stapler of simple, light and effective construction adapted tole readily operated by one hand and applied for the purpose of securing shipping tags or cards to wooden shipping crates, containers, supporting walls, etc., by individually causing staples to be cut from a staple stripand then causing the prongs oi' the out 01f staple to be automatically forced through the material and into the support without bending the staple prongs.

Other and further important objects of this invention will be I apparent from the disclosures in the specification and the accompanying drawings.

This invention (in apreferred form) is illustrated in the drawings and hereinafter more fully described.

Reference numeral 1 indicates a .cylinwooden board or the drical casing or housing havin a cylindrical steel plug or block 2' rigi y secured OFFICE.

in the lower end thereof by any suitable means. The casing sleeve 1 and the block 2 are radially reamed out or cut to afiord a longitudinally directed slot 3 which Opens through the bottom of said casing 1 and said plug 2 as illustrated in Figures 4 and 10. The plug 2 is also ground out or cut at right angles to the slot to afford a pair of oppositely disposed staple guide grooves 4. The plug 2 also has provided therein a radial recess or chamber 5 which communicates with a slot in the casing 2, said slot forming a part of the chamber 5 as illustrated in Figure 6. The chamber 5 is disposed in the same plane as the slot 3 and is wider than said slot. The casing 1 is also provided with a longitudinal slot a short distance from the lower end of said casing as illustrated in Figures 4 and 6. Removably secured to the casingl above the slot 3 and projecting through the plug 2 s a mounting screw 7 which serves to rigidly hold the lower end of a strap spring 8 secured on the exterior of the casing 1. The upper end of the strap spring 8 is provided with a stop hook 9 (Figure 4) which 1s also positioned so that the stop hook is permitted to project through an opening 10 in the casing 1. v .7

The stop hook 9 affords a stop agalnst which a hardened steel plate or lug 11 (Figure 4) is adapted to contact to limit the upward movement of a cylindrical plunger or ram 12 which is slid-ably mounted within the casing 1. The plate or lug 11 is rigidly seated in a recess provided in the ram 12. The ram 12 is provided with a longitudinal slot 13 to permit sliding movement of .said ram. The ram 12 is also provided with an axial bore or passage 1.4 and with a pair of oppositely disposed longitudinal grooves or slots 15 (Figure 5).

Slidably mounted on the exterior of the upper end of the casing is a sleeve 16 having rigidly secured at right angles thereto an arm or handle 17 to permit manual -down-.

ward sliding of said sleeve 16 when it is desired to operate the stapler. The upper end. of the sleeve 16 is closed by a cap 18. A notch or slotted disk 19 is held in place upon the upper end of the sleeve 16 by means of said cap 18. Rigidly secured on the under side f the late 19 is a disk or ring member 20 the mi dle portion of which is provided with an integral collar 21. En-. gage-d around the collar 21 is the upper end of an outer control spring 22 which is disposed within the sleeve 16 and has the lower end thereof engaged around a collar 23 which is integrally formed on the middle portion of a plate or disk 24. The plate 24 is rigidly secured on the upper end of the casing 1. The control spring 22 normally acts to hold the sleeve 16 in its upper position as illustrated in Figure 4. The upward notches in the plate 24 permitting the lower hooked ends 25 of said U-shaped member 26 to project into the ram guide grooves or slots 15. The hooks 25 are positioned to engage beneath hardened steel plates or plugs 27 which are rigidly secured in the sides of the upper end of said ram 12 (Figure 5). The control spring 22 thus acts to hold the slidable sleeve in its upper normal position with the hooks'25 contacting the hardened steel plates 27 thereby limiting the upward 'movement of the sleeve 16 on the casing 1.

Rig-idly secured to the middle portion of the upper plate 19 within the ca 18 is the upper end of a plunger rod 28. The plunger rod 28 extends downwardly through the collar 23 of the lower plate 24" and projects into the upper end of the axial passage 14 provided for the purpose in the ram 12.

. Engaged around the plunger rod 28 is an inner control spring 29 the upper end of which seats against the upper plate 19 while the lower end of the spring 29 seats in a notch provided for the purposes in the upper end of the middle portion of the ram 12.

The spring 29 is provided for the purpose of actuating the ram when the same is released as hereinafter described.

To permit the sleeve to slide downwardly on the casing 1 said sleeve 16 is provided with a longitudinal slot 30 (Figure 2) to permit the sleeve to pass the upper end of the strap spring 8.

The lower end of the ram 12 is rovided with a transverse slot within w ich the upper enlarged end of a ram rod 31 is seated. The ram rod is held in .place by means of a set screw 50 or other suitable means. The ram rod 31 is shaped to permit the same to slide in the guide grooves 4 and is also provided with guide ribs or flanges which are adapted to slidably engage in guide grooves provided in the plug 2.

A staple strip feed mechanism is prov ded on the lower end of the casing 1 and comprises a split sleeve or collar 32 which is rigidlysecured around the exterior of the lower end of the casing 1. Integrally formed on the mounting sleeve 32 in a plane with the handle 17 is a staple strip feed channel or housing 33 having an enlarged portion 34 where the housing joins the mounting sleeve 32. Rigidly secured within the lower portion of the staple feed housing 33 1s a closure block 35 which extends into the chamber 5 provided in the lower end of' the plug 2. The closure block 35 stops short of the staple. guide grooves 4 so that the downward movement of the sleeve 16 on the outlet for a cutofi' staple is not obstructed. The closure block has a longitudinal rib 36 (Figure '9) integrally formed on the top thereof to afford a guide for the strip of staples as they are fed through the housing 33 and into the field of operation of the ram rod 31. Mounted within the housing section 34 above the block 35 is a guide plate 37 (Figure 4) below which the strip of staples is adapted to be advanced to have the individual staples cut therefrom. The end of the block which projects into the plug 2 serves as a die member with which the lower end of the ram rod 31 coacts to afford a v means for cutting off staples one at a time.

Rigidly secured within the casing section 34 of the housing 33 is a mounting plate 38 (Figure 6). Pivotally mounted on the mounting plate 38 is the lower end of a control lever 39 having a tong'ue or finger 40 integrally formed thereon and normally positioned to project through the casing slot 6 and into engagement with a notch formed 1 The finger b in the lower end of the ram 12. 4O coacts with a hardened steel plate 41 which is seated in the ram 12 directly above the recess or notch 42 just described. The lever 39 is held in normal latching position with the finger 4O engaged beneath the hardened steel plate 41 of the ram 12 to hold the ram and the ram rod 31 in elevated position until the said lever is released by a downward movement of the sleeve 16. The

" lever is held in latching position by means of a pivoted arm 42 which is pivotally sup ported on the plate 38 within the housing 34. A spring 43 is mounted within the housing 34 and contacts-the arm 42 thereby resiliently holding the said arm 42 in contact with one, edge of the lever 39 as illustrated-in Figures 4 and 5. Pivoted on the lowerend of the arm 42 is a two arm staple strip feed pawl 44 (Figure 10) with the ends of said pawl members positioned to en:-

gage in a pair of notches 45 formed in the longitudinal edges of a strip of integrally connected staples 46. Each time the control lever 39 is moved back into latching position beneath the ram 12 by means of the control spring 43 and the arm 42, said arm 42 causes I the double pawl members to move forwardly thereby causing the staple strip 46 to be advanced a distance sufiicient to move the innermost staple into a position within the field of operation of the-ram rod 31. A pair of stop pawls 47 are pivotally su ported on the mounting plate 38 within t e housing 34. The stop pawls are controlledby a spring 43 and serve to engage in the notches 45 of the staple strip 46 to prevent the staple strip 46 from moving outwardly awayfrom the plug 2 when the control lever" 39 and the arm 42 are actuated to cause retraction of the said pawls' 44 due to the ram 12. As shown in Figure 10 the stop pawls 47 are connected by a transverse strip of material and are positioned between the feed pawls 44.

The operation is as follows:

It very often becomes necessary to secure shipping tags and the like on wooden contamers, therefore making 1t necessary to either paste the shipping tags in place or nail the same on the side of the box or crate.

The stapler of this invention has been devised fer the specific purpose of providing a ready and easy, single hand operated device whereby shipping tags may be securely fastened upon wooden containers or whereby sheet material may be secured to supports.

The stapler is adapted to cut oil' staples from a staple strip and then ram the pointed prongs of the staple straight into the wooden sides of the container for the purpose of securing a shipping tag or card "in place.

consisting of a plurality of integrally connected staples 46 is inserted through the open endof the staple feed housing 33 over the. longitudinal rib 36'of the die block 35 as illustrated in Figure 9. The inner end of the staple strip projects beyond the inner end of the closure or die block 35 and into plosition ready for use. When When it is desired to use the stapler a strip olds the sleeve 16 inits e-Ie-' its handle To use the device a shipping card or tag h which is to be secured on container is held in position and the stapler is then placed over one corner of the shipping card in a position ready for use. When a wooden crate or the ram 12 is in its elevated position the control lever 39 is engaged beneath the hardened steel plate 41 as shown in Figure 4 thereby holding the ram 12 latched in its upper position. The spring 43 holds the cam arm 42 pressed against the lever 39 and at the same time serves to-hold the feed pawls 44 in a position wherein the strip of staples is held in an advanced position with the innermost staple properly positioned below the ram rod 31. A person usin holds the device by one hand y means of the handle 17 and has only to push downthe stapler wardly on said handle thereby causing the sleeve 16 to slide downwardly on the casing '1 to simultaneously compress both the outer control spring 22 and the. inner control spring 29 into the compressed positions illusthe cutting edge of the die block 35.

trated in Figure 6. When the sleeve 16 reaches a position wherein a bevelled portion 49 (Figure 4) reaches the upper rounded end of the control lever 39, said sleeve 16 acts to auton'iatically throw the lever 39 out wardly thereby retracting the tongue 40 from beneath the hardened steel plate 41 of the ram 12. At the moment the finger 40 of the lever 39 releases the ram 12 the compressed spring 29 acts automatically on the plunger to rapidly force the ram and the ram rod 31 downwardly in the casing 1 causing the lower end of the ram rod to ram against the projecting staple thereby cutting off the staple from the staple strip a ainst 's the staple is severed from the strip the operation of the ram rod continues so that the ram rod forcibly .pushes the staple downwardly out of the lower end of the closure plug 2 with the pointed ends of the staple legs or prongs emerging from the stapler'through the ends of the guide grooves 4 thereby permitting the staple prongs to be rammed directly through the shipping card or material to be held in place. The staple prongs pierce straight into the wood wall or siding of the shipping crate or supporting wall on which the material is to be fastened. The

ejection and ramming of a staple by the .stapler is done almost instantaneously with the operation of the handle 17. After a staple has been rammed in position to hold one corner of the card in place the pressure on the handle 17 is released thereby permitting the compressed spring 22 to act to automatically return the sleeve 16 into its normal raised position until the hooked ends 25 of the strap 26 come into contact with the hardened steel plates 27 of the ram 12. The ram is thereby also returned to its normal position toward the plate 24 thereby causing retraction of the ram rod 31. The upward movement of the ram 12 is limited by means of the stop hook 9 which is integrally formed on the upper end of the strap spring 8. The stop hook 9 is adapted to be contacted by the hardened steel plate 11 which is inserted in a recess in the ram 12.

As the sleeve 16 and the ram 12 are returned to their normal positions the lower notched end of the ram 12 passes the latching edge of the finger 40 on the lever 39.

When this occurs the control spring 43 acting against'the cam arm l2 swings said cam arm about its pivot toward the casing 1, thereby forcing the control lever 39 back into the latching positionillustrated in Figure 4 with the tongue 40 enga ing in the notch beneath the hardened steel plate 41. As the sprin 43 operates the cam arm 42 the lower en of said cam arm 42 operates the teed pawls 44.- thereby causing said pawls to push the staple stri inwardly a predetermined distance to sli e the next staple mto position within the slot 3 with the pointed prongs of the end staple positioned in the guide grooves 4 as shown in Figure 5.

\Vhen the handle 17 is operated to slide the sleeve 16 downwardly on the casing 1 to cause release of the control lever 39 and operation of the ram rod 31 to cut off and ram a staple through a card and into the material forming the container, the control lever 39 swings outwardly and causes the cam arm 42 to swing outwardly therebyv drawing the feed pawls 44; outwardly over the staple strip to engage in the next set of notches ready for the next feeding operation. To hold the" staple strip in position against sliding outwardly when the feed pawls are movedoutwardly the spring controlled stop pawls 47 are provided to act as stops to hold the staple strip in place so that the same cannot slide outwardly over the rib 36 as the feed pawls are retracted into a position to engage in another set of'notclies of said staple strip ready for the next feeding operation.

It will be noted that the device is simple in construction and may be easily used by an inexperienced person torapidly cut off and ram staples through the corners of a shipping tag and into a wooden box or crate to hold the shipping tag or card rigidly secured in place. It will, of course, be understood that any number of staples may be inserted through a shipping card, or that the stapler may be used for securing cards or sheet material on walls or other supporting destination.
