GREASE AND OIL GUN.
To all whom t may concern Be it known that I, ERICH EDELMANN, a citizen of the United States, residing at Chicago, inthe county of Cook and State of Illinois, have invented certain new and useful Improvements in Grease and `Oil Guns,
of which the following is a specification.
My invention has reference to devices com monly called grease guns, which are usually employedfor forcing grease into a location which is not conveniently accessible with the ordinary means ofsupplying grease. My invention, however, is not limited to the use of greasetherewith but is adapted to be used for supplying any material in a fluid, semiluid, paste or other condition which enables it to be forced from the gun.
In grease guns such as have been coinmonly used heretofore, no convenient means has been provided for filling the gun with rease or other material preparatory to use.
hese guns usually consist of a barrel with a spout at one end and a plunger operable in the barrel for pressing the contents out through the spout, and as heretofore constructed it has been necessary to unscrew one or more end caps to fill the gun. This was usually accomplished with considerable inconvenience as a rather long threaded connection .is ordinarily provided, and the threaded connection is often times hard to start. It was especially difficult if it was 'necessary to it the plunger back in the barrel, and in any case, it was hard to get grease down into the barrel from the end opening andthoroughly fill the gun. With my invention it is unnecessary to remove any endcaps orwithdraw the plunger from the barrel, and the gun is easily filled as the barrel is provided with a long opening through which grease or other material may be placed in front of the plunger, which openr ing is provided with a closure which is easily secured in position to afford a tightly closed chamber in wliichpressure is applied tothe grease or other material therein.
The principal objects of my invention are to provide a gun for grease, oil, or other ma-I terial, having an opening with a conveniently operable closing means enabling the gun to be easily and quickly illed without the necessity of removing an end ofthe barrel or cylinder of the gun; to provide a device of this character having an opening in the side wall of the barrel and a closingA member therefor which remains connected Spcification of I-.etters Patent.

Application filed July 2, 1919.# Serial No. 308,236.
y with the barrel during operation of opening and closing the barrel opening; to provide .a gun with a longitudinal opening in the side wall' of the barrel controlled b a panel slidably connected with the barre to provide the panel or closing member'with an improved, conveniently operable catch for holding the panel or closing means in the closed position; to provide a panel or closing means which serves to lock parts of the gun 1n the assembled position and which is connected with the gun so as to prevent'separation or removal of the panel Withoutdisassembling the gun; and in general, to provide an improved grease gun structure having a conveniently operable panel affording,
access to the interior of the gun for filling On the drawings, Figure 1 is a side view of a gun construction in accordance with my.
invention, showing'the panel which affords access to the interior of the barrel; Fig. 2 is an enlarged view of the gun looking at the left hand end of Fig. 1;'Fig. 3 is an enlarged transverse sectional view on the line 3-3 of Fig. 1; Fig. v1 is an enlarged longitudinalsection of the rear end of the gun on the line 4-4 of Fig. 1; Fig, 5 is a view with parts in section on the line 5--5 of Fig. 2 and intermediate portions broken away to permit a large view to be shown; Fig. 6 is an enlarged sectional view on the line 6--6 of Fig. 1; Fig. 7 is a perspective view of the rear end cap; Fig. 8 is a 'perspective view of the rear` end ring; Fig. 9, an enlarged fragmentary sectional view ofthe latch on the line 9 9 of Fig. 1.
Referring to the drawings, the referencer numeral 1 indicates the barrel of the gun which is in the form of a cylindrical tube and has a head 2 threaded onto and closing one end thereof. This head is centrally a'pertured and has an internally threaded bushing or sleeve 3 secured in the aperture and a nozzle or spout 4 threaded into the bushing or sleeve 3 to afford an outlet from the gun for the grease or other material to be ejected therefrom. This spout may be bent laterally, as shown, if desired for lateral discharge. The barrel 1 has an opening 5 inthe side, extending longitudinally thereof from the rear end and terminating a short distance rearwardly of the front end of the barrel, and has a flange 6 at the front end and flanges 7 extending along thesides of the opening, said flanges being pressed latter surface, and flanges 7 serve as guides,
permitting the panel to slide longitudinally of the barrel.
The rear end of the-barrel is externally threaded and has a'cap 9 screwed thereon to close the rear end of the barrel, a ring 10 being insertedin the rear end of the barrel to prevent collapse of the latter, and having a flange 11 which is clamped against the end of the barrel by the cap 9, and the ring 10 thereby locked in place. The rear end of the panel 8 when in the closed position extends under the annular flange 12 of the rear end cap 9, and the latter has an arcuate slot 13 in its rear wall which is adapted to register with the end of the panel 8 when the cap 9 is turned tight on to the end of the barrel 1, so as to permit the panel tobe projected through the rear wall of the cap when it is operated to uncover the opening 5. The flange 11 of the ring 10-is cut away, as at 14' in Fig. 8, a distance slightly greater than' the width of the panel 8, and the ring is clamped in the end of the barrel so that the `cut-away ,portion of the flange 11 registers with the opening 5 in the barrel and the slot 13 of the end cap 9, to permit passage of the panel, and the inner surface of the' flange 12 of the cap 9 is also correspondingly cut away at 15 for the same purpose.
A11 outwardly projecting stud 1.6 is secured to the panel 8 adjacent the forward end, and has a plate 17 inserted thereon and clamped on the panely by a knob 18 which is threaded onto the stud 16. This plate 17 has a raised flange 19 at each side overlying the flanges 7 of the barrel, so that the latter are slidably engaged between the panel 8 and flanges 19 when the knob 18 is screwed down against ythe plate and the panel 8 thereby held up against flanges 7. The rear end of the panel 8 is held up against the flanges 7 byy engagement over the ring 10. A tongue 20 projects forwardly from the plate 17, the latter being slotted at each sidethereof at 21 to afford the required resiliency, an'd this tongue 20 is raised slightly, as shown in Fig. 9, and has the forward end countersunk downwardly at 22 to provide a clasp which engages the flange 6 of the barrel and holds the panel 8 in the closed position. j
The rear end cap 9..is centrally apertured and has a bushing or sleeve 23 secured in the aperture and a threaded plunger stem 24 is fitted to slide in the sleeve or ybushing 23. The outer end of this plunger stem has a handle 25 fixed thereon and a plunger-26 is secured on the inner end of the` stem 24 within the barrell. This plunger may be of cork or an other suitable material closely fitting and slidable longitudinally of the barrel, and is clamped between washers 27 and 28 on the reduced end 29 of the stem 24 by a pair of nuts 30 which are threaded on the forward end of the reduced portion 29. The forward end of the reduced stem 29 is preferably flattened.l or notched longitudinally at 31 and the washer 28 fitted to the flattened or grooved side of the stem to prevent turning of the washer on the stem and avoid loosening of the nuts 30 thereby.
The outer end of the sleeve or bushing 23 is externally threaded, and there is a 'nut 32 internally threaded to engage the threaded stem 24, and having the inner end counter-bored and internally threaded to screw on to the bushing or sleeve- 23, as shown in Fig. 4. This nut 32 has a knurled annular flange 34 to afford a finger grip to facilitate engagement with and disengagement from the bushing or sleeve 23.
In assembling the panel 8 in the barrel, the rino" 10 is inserted in the rear end thereof with the portion thereof from j which the flange 1'1 is lomitted registering with the opening 5 of the barrel, and the` end cap 9 is then screwed on to the end of t-he barrel tight against the ring 10, to clamp the latter firmly in place, and when so engaged the slot 13 and cut-away portion 15 of" the end ca likewise re ister with the opening 5 o the barrel. he panel 8 from which the plate 17 and knob 18 is removed is then inserted from the inside of-the barrel up into position in the opening 5, the rear end thereof being slipped into the arcuate opening provided therefor between the ring 1U and the cut-away part 15 of the cap 9. By thus inserting the rear end of the panel 8 in place, the panel may be lifted up against the flanges 6 and 7 after which the plate 17 is insertedon the stud 16 and the knob 18 screwed on to the stud, thus holding the panel 8 securely in place. Access may then be had to the interior of the barrel by pulling rearwardly on the knob 18 which disengages the clasp 2O from the flangefi, and when the panel is pushed forward to the closed position, the counter-sunk end 22 of the clasp readily rides over Iand re'- en ages the flange 6to hold the panel closed. t will` be observed that the rear end of theanel 8 when placed in position engages in t e cut-away portion 15 of the rear end cap 9 and thereby locks the rear end cap from turnin movement on the end of the barrel 1. rhis isparticularly advantageous in this type of pump as the nut 32 is adapted to be screwed on and ofi` the sleeve 23 of the rear end cap, and such operations might'effect a turning of the cap'9 on the barrel. A
The pump yis adapted to be operated by connection with the bushingQB, or when the nut 1S engaged with` the bushing, may be operated by rotating the stem 24 which by reason of its threaded connection with the nut 32-applies apowerful pressure upon the contents of the gun to expel same therefrom.
.Obviously, tofill the vgunjit is only necessary to withdraw the plunger 26 to the ,rear end and slide the panel 8 rearwardly so that access may bel had to the .interior of the barrel in front -of the plunger, and after filling, the panel is projected forwardly until the clasp 20 engages the flange 6.
This vstructure not only has the advantage that the panel remains connected with the barrel when withdrawnfrom' the -opening 5 and avoids lpossibility of misplacing the panel, but also, as the panel engages under the flanges Gand 7, pressure applied to the contents of the barrel tends to more securely l seal the joint` between the panel and its re-` taining flanges, so as to prevent leakage yor escape of the contentsof the barrel.
lVhile I have shown and described my invention in apreferred` form, I am aware that various changes and modifications may be made without departing from the principles of my invention, the scope of which is to be determined from the appended claims.
