To all whom it may concern:
Be it knowh that I, ALFRED T. FISHER, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Devices. for Inflating Pneumatic Tires, of which the following is a specification.
This invention relates to certain new and useful improvements in mechanism for inflating pneumatic tires, and particularly to the class of air-pumps which are designed to be attached to or carried upon the motor-car or other vehicle proximate to a motor-driven member and normally out of contact with said member, but ca able of being shifted into contact therewit 1, whereby rapid inflation and great compression are obtainable.
The invention consists, essentially, of a pump havin a cylinder or cylinders movabl mounted relative to a bed or frame and a 'ven member-of the motor which furnishes the power necessary to propel the motor-car or other vehicle and means whereby the pump and its adjuncts may be shifted from a normal inoperative position out of contact with the driving connections of the I vehicle into contact with said connections or some member thereof, whereby the power of the motor or other driver is transmitted to the pump to actuate the same and compress air and deliver the same to the tires when in fiation is necessary or desired.
The invention also consists of the parts and the constructions and combinations of parts, which I will hereinafter describe and claim.
In the accompanying drawings, which serve to illustrate the invention, and in which similar reference-numerals indicate like parts in the several views, Figure 1 represents a perspective view of a den le-acting air-pump mechanism and a portion of the driving-motor connection by which said pump may be driven. Fig. 2 is a side elevation of the same, showing parts broken away. Fig. 3 is a horizontal section, and Fig. 4 is a vertical section, of an air-pump of modified form.
In carrying out my invention I may use any desired or well-known form of air-pump,
.the pumps herein shown being only illustrative of two well-known forms which may be employed for carrying out the objects I have in view. In other words, I do not limit my invention to any particular form of pump, except that whatever pump construction be adopted it should have the shiftable cylinder or cylinders and means whereby the same is movable into and out of operative contact with some driving member, as the fly-wheel or other part of the motor with which the ve hicle is supplied.
In Figs. 1 and 2 I illustrate a form of doubleacting pump where the cylinders 10 10 are disposed axially in line, said cylinders being connected to or formin a part of a crankcase 12, open at top and bottom to provide for the movements of the crank 13 and the slotted yoke 14-, to which the inner or adj acent ends of the piston-rods 15 are connected in the usual or any well-known and approved manner. These piston-rods carry pistons 16, which operate in the cylinders to compress the air required for inflating the tires, and that this ob'ect might be satisfactorily obtained I provi e each cylinder with an airinlet valve 17 and an air-outlet valve 18, which valves may be of'any desired or wellknown type, and therefore are not illustrated in detail, as they form no essential part of the claimed novelty of this invention. The outlet-valves 18 connect, by means of a casing or chamber 19, along one side of the cylinder-casing, and in this chamber the compressed air 18 admitted and thence delivered to the tires through an outlet 20 and a flexible hose or tube 21 with appropriate nipples or couplings for connection with the airvalve (not shown) of the tire, a pressure-gage being used, if desired, in connection with the hose or tube to indicate the air-pressure. J ournaled transversely in the cylinder-casing is the crank-shaft 22, having a crank 23, the v journal portion of which carries a box orbearing 24, which is slidably mounted in the slot of the yoke 14, which connects the two piston-rods, and on one end of the crank-shaft is a large gear-wheel 25, which is in mesh with and is driven by a pinion 26 on one end of a counter-shaft 27, extending transversely across the top of the cylinder-casing and mounted in bearings 28, rising from said casing. The opposite end of the counter-shaft carries a friction-wheel 29, which is adapted to be moved into contact with the fly-wheel 30 or other driven member of the motor which is employed to propel the vehicle, and
which motor I do not illustrate, as its type and arrangement are immaterial and form no part of the present invention. It is sufii-- cient to say, however, that my air-pump mechanism may be used with any rotating IIO part of the motor or connections driven thereby and that when the friction -wheel is placed in contact with such driving part the pump will be operated thereby and will rapidly compress the air, which will then be delivered to the tire or tires through the connections before described. As the cylinder casing carries the friction-wheel, it will be manifest that in order to con-' nect and disconnect the same with the driving member of the motor connections rovision must be made for thedbngitu inal movement of the cylinders and frictionwheel and connections toward and from said member, and ,that this essential o eration maybe readily performed I mount t e cylinder-casing u on a sup orting bed-frame 31, which is bol ted or otherwise fixed to some stationary part of the underfi me or other fixed portion of the motor caror vehicle. The precise mounting of the bed-frame is immaterial as long as the same permits the cylinders to be moved to carry the frictionwheel toward and from the driver, whatever is the form and position of the latter. In the arrangement shown in Figs. 1 and 2 the bedframe 31 is provided with longitudinally-extending guides, herein shown in the form of two rods 32,- one along each side and carried by lugs 33 at the ends of the frame; and the cylinder-casing is also provided with rigid lugs 34 on its under side, which lugs 34 are bored to receive the guides or rods 32, whereby the cylinder or cylinders is slidably mounted relative to the bed-frame. Inorder to move the cylinder-casing and its adjuncts, and thereby adjust the same relative to the part which is to drive the same, I provide one end or head of the cylinder-casing with a lug 35, in which is rotatably fixed the journal portion of a screw 36, said screw op eratively engaging a fixed nut or threaded opening 37 in one of the lugs 34 of the bedframe. From this description it will be seen that whenever the pump is in its normal inoperative positionnamely, when the iric tion-wheel is out of driven contact with the driverand it is desired to start the pump to supply compressed air to the tires the operator will turn the screw 36, and thereby move the cylinder-casing and its adjuncts as a single structure relative to the bed-frame and the driver until the friction-wheel is brought into operative engagement when the ump will be started. When the desired in ation of the tires has been accomplished, the turning of the screw in the opposite direction will move the cylinder-casing and its su porting parts, including'the fric-, tion-whee away from the driving connections, and thus stop the operation of the pump' The foregoing results are also obtainable by the use of the pump shown in Figs. 3 and 4, which differs from the pump of Figs. 1 and with said driver,
2 mainly in the arrangement of the pumpcylinders 40, which in said Figs. 3 and 4 are disposed side by side and connect with an end 7 crank-case 41,. across which is journaled the crank shaft .42, whose cranks 43 connect with the rods 44 of the pistonsi45, whereby said pistons are alternately operated in opposite directions to com ress air substantiall in the manner herelnbefore described. In this modified form of pum 'the cylindercasing is provided with the ugs 46, which slidablytfit the rods or guides 47, mounted in the cylinder bed-frame 48, as before described, the adjustment of the cylinders being accomplished, by means of the screw 49, in substantially the same manner as described for the pumpof Figs. 1 and 2.
It is obvious also that I may dispense with the counter-shaft, inion, and .gear of the pum of Figs; 1 and 2 and place the frictionwhee directly on the end of the crank-shaft, as shown at 50 in Fi 3, without departing from the spirit of my invention, which invention in its broader base comprehends any form of, pump cylin er or casing with its piston and actuating mechanism and mechanism by which sald cylinder or-casing and actuating mechanism are as a unitary structure adjustable toward'and from a rotating member of a source of'power, whereby the power of the latter is utilized to operate the pump to compress air for inflation purposes, it being understood, however, that the friction-wheel or primary driven member of the pump is carried on or by the pump-casing or some part connected thereto to move therewith. I also wish to state that I do not limit my invention to the screw mechanism described and shown for adjusting the cylinder or casing, as other forms of mechanisms for accomplishing the same purpose may be used, the screw only being shown as representative of a simple and effective medium for moving the cylinder or casing back and forth relative to the source of power of the motor-car or other vehicle.
In the form of pump shown in Figs. 3 and 4 the crank-case is a. closed one and houses and incloses the crank-shaft and the piston-- rod connections, and thereby protects these parts from dirt, dust, and foreign matter to which they are subject because of the location of the pump on the vehicle.
Having thus described my'invention,what I claim as new, and desire to secure by Letters Patent, is
1. In a device of the character described, the combination with a rotatable member of a power-driven vehicle, of a casing including a pump-cylinder and a dust-proof crank-case, complementary air-compressing mechanism carried by the casing, a fixed guide for the casing, and means whereby the casing is movable on said guide toward and from said rotatable member.
2. In a device of the character described the combination with a bed .frame to be fixed to a stationary part of a motor-vehicle said frame provided with longitudinal guides; a pum including a cylinder, a piston, a iston-ro and a crank-shaft said cylinder s idably mounted on said guides; a frictionwheel carried by the cylinder-casing; and means whereb the cylinder and its adjuncts may be move longitudinally to engage and disengage the friction-wheel with a rotatable part of the vehicle-motor mechanism.
3. In a device of the character described, the combination with a rotatable member of a power-driven vehicle, of a double-acting the case itself and the mechanism which it carries are movable as a unitary structure toward and from said rotatable member.
In testimony whereof I have hereunto set my hand in presence of two subscribing w1tnesses.
ALFRED T. FISHER.
