Application filed June 14,
The invention relates to'air pumps used tor inflating automobile tires, and tor other purposes, and has for its principal object the provision of means by which operation of the pump by hand may be dispensed with, and
consists in the provision of means for operation of the pump piston by foot power.
A further object of the invention is the provision of an attachment for air pumps providing means for operation-0t the pump by foot power, the attachment being collapsible so that the pump and operating mechanism may be conveniently transported and stored. 1 I
The invention will be described inv detail hereinafter and will be found illustrated in the accompanying drawings in which Figure 1 is a side view in elevation of an air pump showing the operating device applied thereto, the device being shown in collapsed position in full lines, and in extended, pumping position, in broken lines,
Figure2 is a front view in elevation showing the pump in collapsed position,
Figure 3 is a transverse sectional view showing the pump operating mechanism,
Figure 4 is a transverse sectional view on a planeat right angles to the plane of the section of Figure 3, I 1
Figure 5 is a. horizontal sectional view on a plane indicated by the line 55 of Figure 1, and
Figure 6 is a tragmental detail of the air delivery tube.
ters are used to designate corresponding parts throughout the several views.
The air pumps shown in the drawings are of conventional reciprocating type having a pump barrel 1, with a reciprocating piston 2 in each barrel and piston rod 3, with an inlet duct 4 controlled by a valve 5, and the outlet 6 in which is the usual check valve (not shown),said air pumps being mounted on 7 the base 7 8 indicates a tubular member supported on the base 7 and 9 a tubular rod slidably mounted in the tubular member 8 and held normally in lowered position by means of a contractile spring 10 terminally engaging the lower end of the tubular member 8 and the upper end of said rod. 11 indicates a handle secured. to the upper end. of the tubular rod In the drawings similar reference charac- 1928.

before raising, it. The upper end of the tubular member 8 1s provided with one or more longitudinal slits '12 intersecting the upper I edge of the tubular member, to permit collapsing of the upper end of the tubular memberto clamp the tubular rod 9 in adjusted position by means of a'screw clamp consisting of a strap 13 having projecting ends 14 Y through which is extended abolt and nut 15 t-Ortll'tUV. the endsot the strap together and clamp the upper end of the tubular member in engagement with the rod 9 as stated;
The upper ends of the piston rods 3 are provided with T-couplings 16 through which an arm 17 1S extended... Secured to thearm 17 between the'T-couplingslti is a. plunger 18 that is U-shape in cross section as shown in Figure 5, said plunger being secured to the 1 arm 17 by-means of an integral tongue 19 on the upper end of the'plunger that is bent around the .arm 17 and has its end secured by means of a bolt-20, 21 designating a. bushing sleeve between said arm 17 andthe se 1 curedtongue' 19f Pivotally secured to the plungjer18-adjacentto: its lower end, is a pedal. 22 having an offset portion 23 to re ceive the pi'vot pin 24, the plunger 18 being slottedas shown at 25 to receive-the pivotedplunger 22 is adapted to be raised as shown in broken lines in Figure 3 when the deviceis not in use. 27 designates a contractile coil spring terminally engaging a hook member 28 secured to the upper end of the rod 9, and engaging at its other end as shown at 29 the lower end of plunger 18, the function of the spring 27 being to normally raise the plunger 18 and with it the pistons 2, for the upstroke of the pistons when the device is in the position indicated in broken lines in Figure 1, the down stroke of the pistons being effected by pressing downwardly on the pedal 22 with the foot of the operator. 30 indicates a guide sleeve secured to the upper end of the plunger 18 and slidably engaging the rod 9, and 31 another guide sleeve secured to the plunger 18 adjacent to the slot 25 and slidably engaging the tubular member 8, the sleeve 30 engaging the upper end of the tubular member 8 serving as to stop to limit the downstroke of the plunger, while the sleeve 31 by engaging the clamp st up 13 serves to limit the up stroke of the plunger under the v impulse of the spring 27.
The delivery tube for the air comprises a flexible tubular member 32 having a conventional delivery nozzle 33 secured thereto at one end and a V-shapedtubular member 34 engaged at its other end with flexible tubes 35 secured to the arms of the member 34 and adapted to be connected with the delivery nozzles of the pumps as shown.
lVh-ile the device disclosed in the drawings includes two pump members that are simultaneously actuated by the operating. device, it will be apparentthatthe device may be applied to a single pump member or may be arranged to operate more than two pump members.
lV-ha-t is claimed is I 1. Anair pump operating device, comprising a plunger adapted to be secured to the piston rod of an air pump, manually operated, means to move said plunger and piston rod downwardly, and resilient means to raise said members.
2. An air pump operating device, comprising a plunger adapted to be secured to )lun er to normall raise it and means to h 1 actuate the plunger against the resistance of the spring.
4. An air pump operating device, comprising an arm adapted to be secured to the piston rod of an air pump, a rod adjustable in relation to thepump, a plunger secured to said-arm, resilient means connecting said rod and plunger to raise the plunger, and meanslto actuate the plunger against said resilient means.
v5. An airpump operating device, comprising a base adapted to support an air pump, a tubular member supported on the base, a rod slidably mounted in saidtubular member, a sprmg terminallyv engaging said rod and tubular member to hold the rod in lowered position, an arm secured to the piston rod. of the air pump, ,a plunger secured to said arm, resilient means connecting said rod and-plunger to normally raise the plunger, and a pedal secured to said plunger for actuating it againstthe resistance ofsaid resilient means. I
6. An air pump operating device, comprisinga base adapted to support an air pump, a tubular member supported 011 the base, a tubular rod slidably mounted in said tubu lar member, a spring terminally engaging the tubular member and the tubular rod, means to hold said rod in extended position relatively to the tubular member and against the. resistance of said spring, an arm secured to the piston rod of the air pump, a plunger sec red to said arm, aspring terminally engaging the rod and plunger to normally raise it, a .pedal secured to the plunger to actuate it against said spring, and guide means secured to said plunger and slidably engaging the rod and tubular member.
