INFLATER FOR PNEUMATIC TIRES.

SPECIFICATION formingpart of Letters Patent No. 591 ,841, dated October 19, 1897.

Application filed Janu 6, 1897. Serial No. 618,200. (No model.) Patented in England December 10, 1896,11'0. 28,239.

To all whom it may concern:

Be it known that I, CHARLES GEORGE I'IEAVEN, jeweler, a subject of the Queen of Great Britain, of 107 Vyse Street, Birmingham, England, have invented certain new and useful Improvements in Inflaters for Inflating Pneumatic Tires and Like Purposes, (for which I have obtained Letters Patent in England dated December 10, 1896, No. 28,239,) of which the following is a specification.

My invention has for its object improvements in inflaters for inflating pneumatic tires and like purposes by which I can more easily and expeditiously operate the same.

In order that my invention may be clearly understood and more easily carried into practical effect, Ihave appended hereunto a sheet of drawings upon which I have illustrated examples of the same.

Figure 1 is an elevation of my inflater in a.

closed position. Fig. 2 is a modification of Fig. 1, showing the plungerD extended or open. Fig. 3 is an elevation of the plunger D.

In carrying my invention into practice I form the outer cylinder A with the cap a, fixed to the bottom end, and formed out of or attached to this cap are the supports or legs a a and a which form a steady for the inflater when operating the same, or in stead of these supports I may hinge two or more pieces a to the bottom for the same purpose, as clearly shown at Fig. 2. The outlet a, into which the valve connection is screwed, is formed close to the bottom. The plunger or piston rodD is hollow and has two slots d and (1 formed in either side, extending nearly the bottom. The top ends d of these slots run at right angles to the parts d and d in opposite directions and are enlarged at the end. I then fix the cap (1 on the top of this plunger and insert the coiledspring S, which is held in position by the cross-pin S, and the usual cap is fixed to the bottom, to which the leather sucker s is attached. This plunger is then placed into the outer cylinder, and the pin 3', which forms a bearing for the coiled spring, passes through two holes formed in the cap a and through the slots d and (1 as clearly shown at Fig. 2. When the plunger is forced downward, the pin slides up the slots and compresses the spring, and the plunger can be held in this closed position by slightly turning it when the pin drops into the enlargements at the ends of the slots 61 as shown at Fig. 1.

To operate my inflater, the plunger is first released and the inflater placed upon the ground, when the plunger is pressed downward by the foot of the operator, and when the pressure is released the action of the spring forces it up again, by which means the tire or other article can be easily and expeditiously inflated. Instead of actuating the plunger by the foot it may be operated by hand if desired.

Vhat I claim, then, is-

In combination, the cylinder, the piston, the hollow piston-rod having the slots therein with rightangular extensions, the spring within the piston-rod and the pin passing through the slots of the rod and held in the cylinder to form both a support for the spring and also a means of locking the piston and rod in closed position by engaging the angular extension of the slot, substantially as described. K

In testimony that I claim the foregoing as my own I aflix my name in the presence of two Witnesses.

CHARLES GEORGE HEAVEN.
