EMILE FRANCKAERTS, OF SAN FRANCISCO, CALIFORNIA.

DOOR-HOLDER.

i 0 @ZZ fio/om it may concern Be. it known that I, EuILE FRANCKAERTS, a citizen of the United States, and a resident of San Francisco, in the county of'San Francisco and State of California, have made certain new and useful Improvements in Door- Holders, of which the following is a specification.

My invention relates to improvements in door holders, and it consists in the combinations, constructions and arrangements herein described and claimed.

An object of my invention is to provide a device for holding a door in open position, which may be readily set or released at will.

A further object of my invention is to provide means for positively holding a door in open position so as to prevent the closing of the same even when considerable force is used, but which will instantly release when a release mechanism is operated, so as to permit the door to close.

A further object of my invention is to provide a door holder having comparatively few parts for accomplishing the above named objects, which is cheaply manufactured, and which is not liable to easily get out of order.

Other objects and advantages will appear in the following specification and the. novel features of the device will be particularly pointed out in the appended claim.

My invention is illustrated in the accompanying drawing forming a part of this application, in which- Figure 1 is a face view of the door holder as applied to a door. Fig. 2 is a sectional view through the door and the door holder. Fig. 3 is a rear view of the door holder. Fig. 4 is a sectional view along the line 4 4 of Fig. 2, and Fig. 5 is a sectional view along the line 5-5 of Fig. 2.

In carrying out my invention I provide a main casing 1, which is of the shape shown in the drawings. It is provided with an upper extended portion 2 and with side lugs 3. The portions 2 and 3 are perforated so as to afford means for attaching the casing to a door.

Arranged to slide within the casing 1 is .an auxiliary casing 4, which is hollow. The rear side of the inner casing 4 is provided with a bearing member 5 having an elongated opening 6. The bearing member 5 is dove-tailed as shown in Figs. 4 and 5, to enter the grooves 1x of the main casing.

Serial No. 793,717.

This provides means for guiding the inner casing in its movement.

Pivotally supported at the lower end of the inner casing is a stop member 7, which bears at its lower end a resilient bu'er 8 of rubber or other suitable material. The upper end of the stop member 7 is pressed upon by a spring 9, which bears on the inner side of the member 5. The stop 8 holds the butter 8 in position Arranged to extend transversely of the device are two partitions, a lower one 10 and an upper one 11. These partitions are of the shape shown in Fig. 5. They are pro vided with central openings arranged to receive a rod 12, which is secured to a cap member 13 at the top of the auxiliary casing 4. The cap 13 is provided with a tongue 13X arranged to enter a slot in the rear part of the casing 4 and is held in position by means of a screw 14. A spiral spring 15 bears at one end on the cap 13, and at the other end of the partition 11.

A locking member 16 like that shown in Fig. 4 has a tongue 16a which passes through the slot in the member 5 and enters an opening in a plate 17 secured to the rear side of the casing 1. The plate 17 is also provided with openings arranged to receive one end of the partit-ions 10 and 11. The locking member 16 passes through an open* ing in the casings 1 and 4, and is provided with an integral extension 16b on the outside thereof. The rod 12 passes through an opening 16c in the locking member 16. A spring 18 normally holds the locking member 16 in such position as to cause the rod 12 to bind against the walls of the opening 16C. The opening 16c in the locking member 16 may, however, be brought into position so as to permit a free movement of the rod by moving the locking member 16 downwardly.

From the foregoing description of the various parts of the device the operation thereof may be readily understood. The apparatus is fastened on to the side of the door near the bottom thereof, as shown in Fig. 2. Now when it is desired to open the door and hold it open, one may place his foot on top of the cap 13 and press downwardly. This causes the casing 4 to slide downwardly within the casing 1, spring 15 being put under tension. The locking member 16 is held by the spring 13 so as to prevent the retraction of the rod 12. Thus the stop member 7 is held in close engagement with the floor,

the rubber buffer preventing the movement of the door. If there is any attempt to move the door, the stop member will swing outwardly into the position shown in dotted lines, eausin a rmer grip of the device on the floor. T e stop member will thus resist any tendency to close the door. Now when it is desired to release the door, the extension 16b of the locking member 16 is pressed downwardly either with the foot or with the finger, thereby releasing the rod l2, which underthe iniuenee of the spring 15, raises the slidable casing 4, together with the stop member 7 from the floor into the position shown in Fig. 2, thereby permitting the door to swing free.

I claim In a door holder, a main outer casing provided with grooves, an auxiliary Casing disposed within said auxiliary casing and slidable with respect thereto, a bearing member arranged to enter the grooves for guiding the inner easing in its movement, a pivoted stop member supported at the lower end of the inner easing, a spring having one end normally pressing upon the upper end of the stop member, and the other end bearing on the inner side of the bearing member, a pair of partitions having alined openings, a eentral clamping member disposed between the partitions and being provided with an opening, a rod Carried by the inner auxiliary Copies of this patent may be obtained for ve cents each, by addressing the Commissioner of Patents, Washington, D. C.
