application inea January 3o, 1922. seriai No. 532,697.
To all whom z5 717m/ concern:
Be it known that ll., Ronnnr MORGAN. a
citizen of the United States, residing at New York. in the county o1' New York and State of New York, have invented certain new and useful Improven'ients in Pumps, of which the following is a specification.
The present invention relates to pumps, and consists in the combinations and arrangements of' elements hereinafter described and particularly set forth in the accompanying claim.
The invention has for its purpose to provide a pump of the single-acting type adapted especially tor intlating pneumatic tires, and 'has t'or its purpose to provide such a pump wherein the piston carries a valve adapted to be unseated on one stroke of the piston for taking in a. charge of air and to be seated on the reverse operation ofV the piston for compressing said air taken in on the previous stroke and forcing the same into the tire to be inflated.
A further purpose of the invention consists in constructing the pump of the minimum number of parts which will operate with the greatest ease and maximum efficiency, and wherein the piston and its coactmg valve will provide a free passage for the air and an air-tight joint on their respective intake and pumping strokes.
The invention further contemplates the construction of a pump of this type wherein the parts may be assembled or disassembled by a simple and easily performed operation, and wherein the form of said parts is such that the pumps may be manufactured in large quantities and at relatively small cost.
The construction oit pump as disclosed herein constitutes an improvement over the type of' pump disclosed in a coi-pending application, in which I am joint inventor, bearing Serial Number 523,186, filed Nov. 2, 1921. and is characterized in that the piston rod is iixedly mounted to the piston and wherein the piston valve is separately mounted on the piston and automatically operates to open and close the piston air passages on the respective strokes of the piston.
The invention is shown by way of illustration in the accompanying drawing, where- 1n:
Figure 1 is a longitudinal sectional view i of the pump, showing the relation of pump and valve at the end stroke thereof;
` F ig. 2 is a similar view, showing the relation of parts at the end of the vreturn `or air-intake stroke;
Fig. 3 is a. detail viewl in end elevation of the piston, and
Fig. 4 is a similar view ot' the piston valve.
Referring to the construction in further detail and wherein like reference characters designate corresponding parts in the dif ferent figures shown, the pump comprises a barrel or casing portion 5 having a screw closure cap 6 at its upper end, and a cap 7, screw connected at the lower end, as shown. Said cap 7 is constructed with a nozzle portion 8 for attachment to the usual rubber hose, and a foot portion 9 is provided as tor pumps of this character.
The piston 10 operates within the barrel portion 5 with a substantially close fit and for which purpose packing rings 11 are provided, as shown. Said piston is designed with a plurality ot' air passageways 12 passing entirely through (see Figure 3) ,and with a central aperture 13, into which is screwed the threaded end portion 14 of the piston rod 15. The usual operating handle 16 for the piston rod is provided.
A valve 17 having a stem 18 screwthread ed thereon is mounted to have limited sliding movement on the piston 10 in the manner shown, and functions to seat and unseat with respect to the valve openings 12 during the compression and intake strokes of the piston, respectively, and in which compressions said piston and valve assume the respective positions shown in Figs. 1 and 2. The head 20 of the valve stem working within the aperture 13 determines the extent of movement of the valve 17 with respect to its seat 21, as will be understood. Inasmuch as said valve 17 is screw-threaded on the stem 18, any adjustment for varying the extent of valve opening may be made.
An aperture 20a is provided in the closure of the compression 'cap 6 for admitting air into the piston .21 and make a perfectly air-tight it.
It is obvious that those skilled in the art may vary the details of construction and arrangement of parts without departing from the spirit of my invention, and, therefore, I do no t wish to be limited to such features except as may be required ,loy the Claim.
Having thus described my invention, what is claimed as new is:
In an air pump for infiating tires, the combination of a cylinder providing an air intake and an air Compression chamber, an apertured cap Closing the air intake end of the cylinder, a piston reeiprocable in the cylinder having central apertures in the upper and lower portions thereof, said piston having air passages therethrough and provided with a valve seat at' its lower end, a
piston rod passing through said Cylinder cap connecting; with the piston at the upper central aperture thereof, and leaving a free ture.
