GEEASE- GUN.
T0 @ZZ aLl/1,0m, t may concern: l
Be it known that ll, ROBERT S. l'lronisn, a subject oi` the-King of Hungary, residing at Tuckahoe, in the county-of lVestchester and State ot New Yprk, have invented certain new and i'siful improvements in y(irease'ti'uns, of which the following is a specification,
This invention relates to grease guns, the object of the invention being to provide a simple, inexpensive and effective grease gun which may be used either for oil or heavy grease as occasion may require and in which the operation of the piston Will be facilitated, and in which also the piston may be readily locked, held or retained against manipulation in one Way by a very simple device, 'which locking or holding means will also assist in reducing friction.
ln the drawings accompanying and :torming part of this specification, Figure l is an exterior View of this improved grease gun; Fig, 2 is a partly sectional view thereoi; Figs. 3 and Ilare detail enlarged views illustrating the position of the holding device at different times; and Figs. 5 and 6 are cross-sectional views illustrating respectively the position of the holding device shown in Figs. /l and Similar characters of reference indicate corresponding parts throughout the several iigures of the drawings.
This improved grease gun comprises the usual cylinder 2 having a removable cap 3, the removal oi'ivhich will permit the heavy grease to be inserted. rlhis cap is provided with any desired form of nozzle 4i.
lNithin the gunl is located some suitable form of piston 5 connected to a plunger or piston rod 6 which is threaded as at 7, and provided with a handle as at 8 by means ol- Which the plunger may be either recipro cated, that is, moved or slid back and forth or rotated. Carried by the rear of the cylinder or that end opposite from the nozzle is' a removable closurevor cap i) having a tubular extension 10 provided with an opening 11 therein in which is located a ball l2 which cooperates` rwith the thread of the plunger. This ballis maintained in its opening or pocket ll by means oi a-rotatable housing or colla; 12 located on the extension 10 of the cap. The rotatable movement of this housing or collar is limited by means of'a Specication of Letters Patent.

pin'l carried by the extension l0, the pin projecting into a recessed portion 14 of the collar. Ilhe collar is also provided with an opening` l2, `which on the rotation ofthe collar, can be made to register with the opening er pocket 1l in the extension, a pin l5 extending across the opening in the collar to prevent the ball from falling out. The thread of the plunger is formed as a quick Worm, 'for instance three threads to the inch.
ln the present improvement when it is desired to slide the plunger as with ordinary Huid grease, such as oil, it is merely necessary to turn the knurled collar so that the opening therein will register with the opening in the extension, whereupon the ball will have suicient play to permit the plunger to be reciprooated or slid back and forth, the opening in the collar permitting this play oi the ball. When, however, it is desired to use the gun with heavy grease diiiieult to push out by merely pushing'upon the plunger, it is necessary that the piston be rotated by means oi' the screw and for this purpose the collar is simply turned so as to carry the opening thereof away 'from the ball, whereupon the ball is locked or held as it were in the grooves of the threads so that it is only possible to operate the 'piston by rotating the plunger While the ball at the saine time also constitutes an anti-friction bearing to reduce friction during this operation. lt will thus be observed that by means of this holding device the piston can be locked or unlocked at any position, throughout its entire length as occasion may require.
