Claims. (Cl.221-47.3)
This invention relates to lubricating devices and more particularly to lubricant dispensers for dispensing lubricant under pressure. 4
One of the objects of the invention is to provide 5 a lubricant dispenser which is supplied with lubricant by a replaceable cartridge.
Another object is to provide a lubricant dispenser in which the end portion of a cartridge is severed by its assembly in the gun and may be forced through the cartridge to displace the contents therefrom.
Still another object is to provide a lubricant' dispenser for use with a cartridge in which entry of a piston into the cartridge is facilitated.
According toV one arrangement, these and other objects are attained by providing a lubricant dispenser including a cylindrical shell to receive a cartridge and a cap for the shell including an annular knife to cut the top out pf the cartridge. A piston is provided which may slide into the knife and, after the knife has entered the cartridge, readily slide out of the knife and into the cartridge to displace its contents.
Other and further objections, advantages and novel features of the invention will be apparent from the following detailed description when taken in connection with the Vaccompanying drawings. It is to be understood, however, that the drawings are for the purpose of illustration only and are not to be taken as a definition of the scope of the invention, reference being haddor this purpose to the appended claims.
In the drawings wherein like reference numerals indicate likeparts throughout the several views.
Fig. 1 is a central sectional view with parts in elevation oi a lubricant dispenser embodying the invention;
Fig. 2 is an elevation .of a cartridge to be used with the dispenser of Fig. 1;
Fig. 3 is a -partial view of the dispenser of Fig. 1 with the cap removed;
Fig. 4 is a sectional view of a modified cap construction; y
Fig. 5 is a view similar to Fig. 4 showing another modiilcation; and
Fig. 6 is a sectional view of a modified piston construction. 4
The lubricant dispenser illustrated in the drawings is constituted by a grease pump comprising a body member l0 having a cylindrical bore I2 therein in which a piston I4 reciprocates to displace lubricant therefrom under high pressure. 'I'he cylinder I2 has an inlet borev i6 and anD 55- outlet Il provided with a suitable check valve 20.
A nozzle 22 of any desired type is connected to the outlet I8 for servicing 'a suitable lubricant receiving fitting (not shown). As illustrated, the dispenser is of the hand operated type, a handle 24 being provided on the plunger I4 for manual operation thereof although, if desired, the plunger i4 might be operated by any suitable power mechanism.
A cylindrical shell 26 is secured to the casting Ill by means of a gland nut 28, a washer 30 of leather or other suitable material being provided between the shell 26 and body Ill to form a tight seal. The shell 26 is designed to receive a lubricant cartidge 32 shown as formed of paper or other fibrous material which is inserted into the outer open end of the shell and which when in position is in communication with the pump inlet I6. As shown in Fig. 2. the cartridgeis provided with removablev end closures 34, the inner of which is preferably removed before insertion in the shell. When assembled in the shell the outer end of the cartridge projects therefrom a substantial distance to facilitate grasping by an operator to remove the cartridge after its con-- tents have been discharged.
'I'he end of the shell is closed by an end member comprising a cap 36 having secured therein an annular knife 36 which -is provided with sloping teeth 40. The end member is preferably secured to the shell by a bayonet joint formed by projecting lugs 42 on the shell which co-operate with suitable depressed slots 44 in the cap. By this means the cap is securely fastened to the shell by combined axial and turning movements. It will be noted that theslots 44 slope axially of the capl so that turning movement draws it onto the shell, friction of the parts being suihcient to prevent it 4from turning on.
In assembling the cap on-the shell, the teeth 40 will penetrate the outer end of the cartridge adjacent its periphery and will cut out a circular disc therefrom substantially equal in diameter to the inside of the cartridge. This cutting action is facilitated by the combined axial and rotary movement of the cap. It will be noted that the annular knife 38 is spaced from the inner wall of cap 36 to provide an annular chamber which is adapted to receive the end of the cartridge and hold it securely in place.
A suitable piston 46 isy provided in the cap, having an annular sealing washer 48 for sealing against the inner surface of the cartridge. Preferably a compression spring 50 is provided, urging the piston toward the pump and a suitable handle 52 may also be secured to the piston and extend through the end of the cap for withdrawing the piston, if desired. The handle is preferably provided with a transverse pin 54, cooperating with a slotted opening'56 in the end of the cap for retaining the piston in its outer position.'
It will be noted trom Fig. 1 that when the cartridge is assembled in the shell 26, it engages the washer 3,0 which provides a seal around the periphery of the cartridge end to prevent leakage of lubricant. Preferably the end of the washer is cut away, as indicated at 58, whereby any lubricant which leaks around the end of the cartridge will get in behind the edge of the washer 30 and press it against the cartridge to insure sealing thereof.
In using the lubricant dispenser so far described, one end closure 34 of a cartridge is removed and it is inserted in the shell 26 as shown in Figs. 1 and 3, with its other end projecting therefrom. The cap 36 is then assembled on the end of the shell, the knife 3B severing the end of the cartridge during the assembling operation. During assembly the piston 46 has preferably been locked in its outer position, shown ln Fig. 3,
by pulling the pin 54 through slot 56. and turning the rod to prevent forward movement of the piston.
After the cap is assembled on the shell, rod 52 is again turned to permit the pin 54 to pass through the slot 56 and the spring 50 will then urge the piston forwardly to force grease from the cartridge -through inlet |6 into the pump. Thereafter operation of the plunger I4 will dispense lubricant from the pump.
It will be noted that when the piston is in its withdrawn position Iit is Within the knife 38 so that when the parts are assembled the piston can readily slide out of the knife 38 into the cartridge. The cut-out end of the cartridge, being substantially the same size as its inner diameter, serves as a piston-faci`ng to displace lubricant from the cartridge'., but any lubricant which leaks past this cut-out end is stopped by the washer 48 and prevented :Qompassing the piston.
Figure 4 shows a modication of theinvention, parts therein similar to the parts of Figures Ito 3 being indicated by the same reference numerals v plus |00. In this modication the knife te't |40 are secured to the piston |46 rather than to; the cap |36 by suitable fastening means such as rivets |60. The cap is also formed with a portion |62 whose internal diameter is substantially equal to the external diameter of the cartridge end closure and a portion |64 whose internal diameter is substantially the same as that of the inside of the cartridge, the two portions being separated by an off-set shoulder on which the end of the cartridge is adapted to seat.
In assembling the cap of Fig. 4 on a gun, the piston is withdrawn into the portion |64 as shown and after assembly the piston may be turned to cut outY the end of the cartridge. When pin |54 is aligned with slot |56 the piston may move forward into the cartridge, reduced portion |64 of the cap guiding the piston smoothly into the end of the cartridge.
In the modification of Fig. 5 partscorresponding to like parts in Fig. 4 are indicated by the same reference numerals plus |00. This modification is substantially the same as the modification of Fig. 4 except that a single knife tooth 2.40 is provided instead of an annular series and it is consequently necessary to rotate the piston through a complete revolution to cut out the end of the cartridge. Otherwise the modification of Fig. 5 is used in the same manner as that of Fig. 4.
Fig. 6 illustrates a modified piston construction to take the place of either of the pistons shown in Figs. 4 or 5, parts therein corresponding to like parts in Fig. 4 being indicated by the same reference numerals plus 200. In this modification the piston 346 is made up of a stamping 366 to which the piston rod 352 is suitably secured and a stamping 368 overlying the stamping 366 and having -itsperipheral edge turned up and formed with knife teeth 340. Stampings 366 and 368 are spaced at their peripheries to receive the packing 348 and the turnedup ange on stamping 368 is preferably offset as shown so that the outer faces of teeth 340 lie substantially flush with the outer surface of the packing.
In each of the forms shown in Figs. 4, 5, and 6 the piston rods are preferably rigidly secured t0 the pistons to facilitate turning the pistons to cut out the ends of associated cartridges. The body member of a grease pump for use with any of these pistons is preferably provided with an annular groove 10 as shown in Fig. 1 to receive the knife when the piston is in its innermost position. By this lmeans clearance is provided for the knife to prevent damaging thereof through contact with the body portion and to permit the piston to move into contact with the body portion thereby discharging all of the grease in the cartridge.
While several modifications of the invention have been shown and described, it will be apparent that many changes might be made and it is not intended to be limited to any of the forms shown or otherwise than by the terms of the appended claims.
