Specification of Letters Patent. Patented De 19, 191a Application filed Noggtnber 29, 1915. Serial No. 64,101.

T (ill whom it may concern:

Be it known that I, CHARLES E. WARWICK, a citizen of the'United States, residingat Vicksbui' in the county of Warren and State of 'ssissippi, have invented certain new and useful Improvements in Grease I Guns, of which the following is a specithe Wheels of the cars come into fication. I This invention has relation to certain new and useful improvements v1n grease guns,

and has for its primary object the provision,

provision of a special form of shoe for thegrease gun to properly apply the oil or grease tothe rail.

Wish the above and other objects in view, the invention resides in the novel construction, combination, and arrangement of parts as-hereinafter set forth in the specification, pointed out in the claims, and'shown in the drawings, in which- Figure 1 is an elevation of the complete device in use; Fig. 2 is an elevation at right of the device engaged with a rail; Fig. 3 is an enlarged elevation with the shoe and the rail in section.

Referring more particularly to the drawings in which similar reference characters designate corresponding parts throughout the several views, 1 designates the cylinder or-body of the device adapted to contain the oil or grease to be applied to the rail 2, said cylinder or bodyl having apiston 3- mounted therein upon the threaded piston rod 4which has movement through the head 5 secured upon the outer end or upper end of said cylinder or body 1. It will be understood that a suitable operating wheel 6 is mounted upon the outer end of the threaded piston rod 4 to revolve the latter and therebymove the piston 3 in said cylinder or body 1.

A feed pipe has one end secured in the conical lower end 8 of the cylinder or body 1, while its opposite end is threaded in the .grea'se supplying shoe 9 and it will be evident that as the piston 3 is forced toward the lower end of said cylinder or body 1, the oil or grease will be forced downwardly through the feed pipe 7.

The shoe 9'is bifurcated to form tongues 10 and 11 for engaging the respective upper and side faces of the head or tread portion of the rail 2. The tongue 10 is flat to rest upon the upper face of the rail 2, as shown in Figs. 1 and 3 of the drawings and extends at an acute angle to the main portion of the shoe 9, while the tongue 11 is curved. as shown in Figs. 1 and 3, and positioned at about right angles'to the tongue 10, thereby forming an oilor grease pocket 12 to the side of the rail 2 and above the point at which the tongue 11 is engaged with said rail 2. Oil or grease is conducted from the feed pipe 7 to the oil or grease pocket 12 by the oil or grease conducting passage 13,'while the second oil or grease conducting passage 14 serves to conduct oil or grease from the feed pipe 7 to the upper face of the rail 2. The

oil or grease conducting passages 13 and 14 are separated by a suitable partition 15 riding upon the upper edge of the rail 2 when the device is in operation. a

When thin oil or grease is used, the oil or grease conducting passage 13 may be closed, if desired, in order that the thin oil or grease may be applied only to the upper face of the rail 2 at gage line and then properly distributed by the tongue 11 of the angles to Fig. 1 showing the lower portion shoe 9. When a thick or heavy oil or grease is used, however, it may be desirable to close the passage 14 in order that the heavy oil or grease may be directed only to the side of the rail tread before being distributed by the tongues 10 and 11 of the shoe 9. It will also be understood that the ends of the tongues 10 and 11 may be curved upwardly, if desired, to permit the device to readily slide over lips in joints or guard rails. It will further be seen that by providing this pocket 12, the gravity or flow of the oil or grease keeps this pocket filled and thereby causes a continuous supply of oil or grease to the It willbe readily seen that the shoe 9. tongue 10 serves only as a rider to guide the shoe on the top tread of rail, while the tongue 11 is extended to do all of the spreading. This will prevent grease being applied to the top of the rail and causing a collision.

While the preferred embodiments of the invention have been shown and described, it

details of construction, and arrangement of parts may be resorted to within the scope of the appended claims without departing from the spirit of the invention or sacrificing any .of the advantages of the same.

What is claimed is:

1. A grease gun comprisinga shoe, rail engaging tongues carried b said shoe and positioned at an angle to t e latter and to one another, said shoe and tongues being arranged to form a pocket to one side of said rail when said tongues are engaged therewith, a lubricant feed pipe connected with said shoe, said shoe having separate conducting passages formed therein to conduct a lubricant from said feed pipe to said pocket and to the upper face ofsaid rail, and means for supplying a lubricant to said feed pipe.

per e ge of said curved tongue, a lubricant feed pipe connected with said shoe, said shoe having opposltely extended separate passages formed in its central portionand leading from said feed pipe to the-working face of the straight tongue and the pocket whereby the lubricant will be conducted to both,

rail with which said tongues are faces of the engaged.

' In testimony whereof I afiix my signature of two witnesses.
