HORATIO SEYMOUR BILLS, OF IONIA, MICHIGAN, ASSIGNOR TO JOHN Il. MITCHELL, OF SAME PLACE.
Ain-PUMP.
SPECIFICATION forming part of Letters Patent No. 587,638, dated August 3, 189'?.
Application filed December 19,1896. Serial No. 616,278. (No model.)
To all whom t may concern:
Be it known that I, HoRATlo SEYMOUR BILLS, a citizen of the United States, residing at Ionia, in the county of Ionia and State of Michigan, have invented certain -new and useful Improvements in Air-Pumps and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
My invention relates to air-pumps, more particularly to double-acting mechanical airpumps. v
The object of my invention is to producea simple, cheap, and durable air-pump capable of being operated by hand, that will deliver practically a continuous stream of compressed air into a tubular tire of a bicyclewheel, or that may be employed for other purposes calling for an uninterrupted gaseous or liquid jet.
I accomplish the objects stated by constructing a suitable cylinder having inletvalves, a piston-rod consisting of longitudinal compartments, a piston provided with airducts connecting the compartments of pistonrod and opposite faces or sides of piston, cornbined with a valve arranged to close the airducts leading to one face, at the same time opening the air-ducts to the opposite face of the piston and alternating those operations regularly when actuated.
Referring to the accompanying drawings, wherein like numerals are used to designate like parts throughout the several views, Figure 1 represents a vertical mid-sectional View of my invention; Fig. 2, a top plan view of the perforated valve-disk and Fig. 3,an enlarged vertical section of the juncture of piston-rod and piston, enabling the construction and mode of operation of the valve-governing piston-rod orifices and-piston air-ducts to be more clearly seen and understood. y
Considering Fig. 1, numeral 1 designates the cylinder, having an oritiee 2 through a head 3, the orifice being concave upon the inside to receive a ball-valve 4, the play of which is limited by the basket 5. Any form of inlet-valve might clearly be selected to replaceV the ball. Head 3 possesses also a central oriice, which is continued through a projecting eXteriorly-threaded nipple 6. An interiorly-threaded gland 7 engages the nipple, and between them a ring 0f packing Smay be compressed. The opposite end of cylinder 1 is open and exteriorly threaded, being normally closed by a screw-cap 9, which is provided usually with a central orifice 10, continued slightly below the inner surface of the cap by a narrow flange 11. Upon the outside the cap 9 is spanned by the curving legs of a spider 12. IVhile not absolutely essential,
, the spider is useful in preventing the hand from coming intimately into Contact with cap 9 and closing orifice 10. Less in diameterthan the interior of cap 9 and exterior diameter of cylinder 1 is the valve-disk 13, having a solid center and rows of perforations 14. (See Fig. 2.) Disk 13 is adapted to rise and fall within cap 9, and it normally rests upon the end of the cylinder, as shown. In practice I may modify the inlet-valve just described or substitute any convenient known equivalent therefor. The construction speciiied being of extreme simplicity cannot fail or get out of orderin service, and the position of cap 9 may be permanently fixed by soldering or in another eiiective manner made fast to the cylinder.
23 represents the piston, having a central threaded orifice in engagement with the closed end of the hollow piston-rod, as clearly shown in Figs. 1 and 3, and leading to opposite faces or sides of the piston are formed the airducts-lei`t 24, right 2li-as drawn. A suitable ring of packing 26 encircles the piston.
Hollow piston-rod 15 extendsthrough the central oriiiee in cylinder-head 3 and through the stuffing-box device described as far as may be desired, and a collarA 27, from which project handles-left 28, right 29-is secured uponthe rod at a convenient point.
I do not confine myself to the use of any special form of valve at any point in my invention.
The mode of operation will now be readily followed. Assume the parts to be assembled and to be relatively situated as shown in Fig. 1. Grasping the cylinder in one hand and handles 28 29 in the other, let the cylinder be caused to move from the handles, head 3 apv proaching the piston 23. Compression of air below the piston results, the ball-valve 4 closes, the air rushes through duct 25 and orice 20, driving the spool-valve 21 toward and closing orifice 19, and having no other avenue of escape traverses the right compartment (marked ce) of the piston-rod. s Meantime air enters above the piston through oriiice 10 in cap 9 by way of perforations 14 in valve-disk 13. The piston and head 3 being in close proximity, let the reciprocal operation begin, the piston approaching cap 9. Disk 13, lifted by the compression now above the piston, closes the oriiice encircled by flange 11. The air rushes through duct 24 and orifice 19, driving the spool-valve forward and closing orifice 20. Under these assumed conditions the only path for the air is supplied by the left-hand compartment of the hollow rod, (marked h.) External airfollows the piston lthrough oriiice2 in head 3. Performed with ordinary rapidity these operations cause a practically constant blast to be delivered at end 16 of the piston-rod.
Having thus fully described my invention, what I claim, and desire to protect by Letters Patent of the United States, is-
1. In an air-pump, the combination of a cylinder having inlet-valves, said cylinder provided with suitable heads, one head having a piston-rod aperture, a hollow piston-rod divided longitudinally into independent compartments, said piston-rod having one end closed, said piston-rod having orifices opening into said compartments, a piston having ducts leading to its opposite faces, said piston being secured to said piston-rod and the inner mouths of said ducts arranged to register with said orifices, and valves for simultaneously opening and closing said compartments alternately into said cylinder upon opposite sides of the piston by way of said ducts, substantially as described.
