PUMPING ATTACHMENT FOR PNEUMATIC TIRE$.
SPECIFICATION forming part of Letters Patent N 0. 655,932, dated August 14, 1900. Application filed November 23,1899. Serial No. 738,102. (No model.)
To all whom, zit may concern: t
Be it known that I, HENRY LAVIERS, acitizen of the United States, residing at Wellston, in the county of Jackson and Stateof Ohio, have invented a newand useful PumpingAttachment for Pneumatic Tires, of which the following is a specification.
This invention relates to pneumatic vehicle-tires in general, and more particularly to that class known as double-tn be tires,comprising an exterior shoe or casing and an interior air-tube of resilient and elastic material, the object of the invention being to provide a device which may be applied to any of the present forms of double-tube tires and which will necessitate only the formation of an additional hole through the felly of a wheel to enable its application, the attachment when in place acting to automatically pump ail-into the air-tube of the tire.
In the drawings forming a portion of this specification, and in which similar numerals of reference designate like and corresponding parts in the several views, Figure 1 is a sectional view taken through the folly and the tire of a vehicle-wheel in a plane at right angles to the axis of the wheel and showing a portion of the wheel with the application of the presentinvention thereto. Fig. 2 is a detail perspective view showing a form of valve that may be employed. Fig. 3 is a vertical central section of a portion of a valve tube or casing and illustrating in elevation the location of the valve. Fig. :l: is a section on line 4 4 of Fig. 3.
Referring now to the drawings,5 represents a portion of the telly of a vehicle-wheel, to which the spokes 6 are secured in the usual manner. Upon the folly 5 is placed adoubletube tire comprising a shoe 7, which may be of any style, and in which shoe or casing is disposed an air-tube 8, having a stem 9, which is passed through an opening 10 in the inner periphery of the felly in the usual manher. This portion of the structure illustrated is old and may represent any style of tire, whether laced or otherwise secured.
In applying the present invention to the tire the pumping-bulb is placed within the shoe and may be disposed between the ends of the air-tube or may lie against it at any with the bulb at preferably adjacent points are two stems 12 and 13, in each of which is disposed a valve-casing 14 and 15, respectively. In each valve-casing is formed a valveseat 16, the seat within the casing 15 being adapted to receive an inwardly-opening valve 17, while the seat within the casing 14 receives an outwardly-opening valve 18. In the present instance the seats 16 are shown asinwardly-directed continuous flanges,while the valves comprise heads 19 and diminished threaded stems 20, upon which are disposed oblong nuts 21. The sides of the heads ad jacent the stems are adapted to engage the seats when closing their respective casings, while the nuts 21 engage the opposite sides of the seats and limit the movement of the valves to their open positions. The nuts are somewhat less in width than the valve-openings through the seats to permit the passage of air, as illustrated in Fig. 4. I
The valve-casing 14 projects outwardly of the stem 12 and has a flexible tube 22 connected therewith and leading to a metal tube 23, which is inserted in the stem 9. The up per end of the stem 13 is provided with a foraminous guard 24.
From the above description it will be seen that with the employment of the present attachment as the wheel is rotated while supporting the weight of the rider or of the vehicle the bulb 11 will he compressed once for each rotation, and it will expand after each compression. The result will be that the bulb will have a pump action and will draw out side air inwardly through the casing 15 and will discharge it through the casing 14, from whence it will pass through the tube 22 and into the air-tube 8, the action being contin ued until an equilibrium is established between the pressure in the air-tube and the pressure in the bulb.
It is known to be old to specially construct a tire comprising compartments having valve communications, whereby air is forced from one to another; but the object of the present invention is to provide an attachment which may be applied to any common form of tire of the double-tube style and which will require only the formation of a second hole through the felly of the Wheel to which the tire is applied.
It will of course be understood that in practice the specific shape of the pumping-bulb may be varied, that any desired style of valve may be employed, and that various modifications may be made Without departing from the spirit of the invention.
What is claimed is In adevice of the class described, the combination with a rim, of an outer tube or shoe,
an inner air-tube arranged within the outer tube or shoe and having its ends closed and spaced apart, a separate and independent compressible air-bulb located within the outer tubeor shoe and arranged on the exterior of the inner air-tube in the space between the closed ends thereof, the ends of the air-bulb abutting against the outer faces of the ends of the inner air-tube, an air-inlet valve communicating with the bulb and supported by the rim, and the exterior feed-tube having its ends supported by the rim and communieating with the bulb and with the inner airtube, said feed-tube being provided with a suitable valve, substantially as described.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
HENRY LAVIERS. Witnesses:
W. R. DAVIS, F. E. RIDGWAY.
