FLUID DISPENS ING APPARATUS Filed March 24, 1931 2 sheats shea't 2 HGZZZ Patented Oct. 17, 1933 UNITED STATES FLUID-DISPENSIN G APPARATUS I Charles M. Tursky, Philadelphia, Pa., assignor to Service Station Equipment Company, Conshoh'ocken, Pa., a corporation of Delaware Application March 24', 1931. Serial No. 524,871 Claims. (01. 299-78) My invention is applicable to apparatus for dispensing fluids to motor vehicles, and particularly for dispensation of compressed air for infiation of vehicle tires through a hose-provided 5 with a check valve fitting at its discharge end, which hose is normally retracted and wound on a reel by a spring device appurtenant to the reel but which hose is adapted to be withdrawn from the reel more or less during each dispensing operation. It is the practice of operators to let go of such hose after each dispensing operation and permit it to be automatically rewound by the action of the reel spring, and it is customary to provide the valve fitting at the end of the hose with a guard ring of rubber or similar resilient material back of it to minimize the shock of contact of said fitting with thc casing or frame in which the reel is mounted for rotation. Such hose reel structures are of several types respectively adapted for suspension from ceilings or side walls and for erection upon fioors or pavements, the latter being known as curb stands.

The compressed air for such apparatus is ordi-' narily supplied by an electrically operative pump which is automatically set in operation either by the withdrawal of the hose from the reel or when the pressure of the air in a storage tank is reduced below a predetermined degree. In any case, the unauthorized use of such apparatus subjects the owner to loss and expense. Therefore, it is the object andefiect of my invention to provide means to prevent the unauthorized use of such fluid dispensing apparatus including lockable means for secluding the discharge end of the hose.

As hereinafter described, such lockable means is embodied in a housing containing a spring pressed buffer device adapted to minimize the shock of impact of the valve fitting at the termination of each rewinding operation of the hose; which bufier device is more efiicient and durable than the mere bufier ring on the hose and also serves to thrust the valve fitting out of seclusion into operative position when the lockable means aforesaid is released.

My invention includes the various novel features of construction and arrangement hereinafter more definitely specified.

In said drawings; Fig. I is a front view of a convenient embodiment of my invention with the housing door open showing the front view of the buifer mechanism.

55 Fig. 11 is an elevation 01 the right hand side 01. the structure shown in Fig. I, with the bufier mechanism retracted and the door locked.

Fig. 111 is a vertical sectional view of said structure, taken on the line III, III in Fig. I, in the direction of the arrows on said line.

Fig. IV is a fragmentary plan sectional view, taken on the line IV, IV in Fig. I. i

In said figures; the hose 1 is provided with the check valve fitting 2 at its discharge end backed by the buffer ring 3 which when the hose is retracted by the spring reel device aforesaid bears upon the circular series of four bufler rollers 4. Said rollers 4 are conveniently formed of rubber and are independently journaled on respective shafts 5 which are mounted in the inwardly turned flanges 6 on the bearing frame plate 7 which is conveniently formed of pressed sheet metal and rigidly connected, conveniently by the two screws 8, with the buller carriage 10which is a cylindrical tubular ring mounted to reciprocate between the three guide ribs 11 in the housing 12.

As shown in Fig. I, said housing -.12 has a series of openings 13 for screws by which it may be attached to the frame or casing 14 in which the hose reel is mounted. Said ribs 11 are respectively. formed on the three housing bars 15 which are in unitary relation with the spider plate 16 at their inner ends.

Said buffer carriage 10 has the spring plunger 17 rigidly'connected therewith, as indicated in Fig. IV, and said plunger is mounted to recipro cate in the bearing bracket 19 on said plate 16 at the inner end of said housing 12. The spring 20 which encircles said plunger 17 bears at its outer end upon said carriage 10 and at its inner end upon said bracket 19 and tends to thrust said carriage outwardly in said housing, but such movement is limited by the cotter pin 21 which extends through said plunger 17 and is adapted to encounter the inner face of said bracket 19, as shown in Fig. IV, when said carriage is in its outermost position shown in Figs. III. and IV.

Said housing 12 has the hinge lugs 22 in spaced relation supporting the pintle 23 which extends through the lug 24 on the door 25 which is thus hingedly connected with said housing. Said housing has the lock lug 27 which fits through the notch 28 in said door 25 when the latter is shut and has the opening 29 therethrough, best shown in Fig. I11, to receive the staple 30 of the padlock 31 when said door 25 is in closed position, as shown in Fig. H.

As shown in Fig. 111, said bufler device normally presents the hose fitting 2 projecting from the housing 12 so that it may be readily grasped by the operator who desires to dispense the fluid and, when the operator releases said hose after the dispensing operation, the impact of the bulier 3 when the hose 1 is withdrawn to the position shown in Fig. 111 is received by the spring pressed rollers 4 on the carriage 10 which yieldsto the right in Fig. Ill compressing the spring 20 to miniinto the housing 12 in which it is secluded by closing the door 25 and locking it with said padlock 31, as shown in Fig. II.

I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as it is obvious that various modiflcations may be made therein without departing from the essential features of my invention, as defined in the appended claims.

I claim:

1. In a fluid dispensing apparatus, the combination with a hose having a valve fitting at the discharge end thereof; of a housing for said hose;

resilient buffer means in said housing adapted to yieldingly stress said hose fitting toward the exterior of said housing, including a carriage mounted to reciprocate in said housing; bufier rollers mounted on said carriage, embracing said hose behind said fitting; a spring normally stresslng said carriage and fitting toward the exterior of saidhousing; and means limiting the movement of said carriage by said spring.

2. In a fluid dispensing apparatus, the. combination with a hose having a valve fitting at the discharge end thereof; of a housing for said hose; bufier means in said housing adapted to yieldingly stress said hose fitting toward the exterior of said housing, including a carriage mounted to reciprocate in said housing; buffer rollers mounted on said carriage, embracing said hose behind said fitting; and a spring normally stressing said carriage and. fitting toward the exterior of said housing.

3. In a fluid dispensing apparatus, the com-- bination with a hose; of a housing for said hose; bufier means in said housing adapted to yieldingly stress said hose toward the exterior of said housing, including a carriage mounted to reciprocate in said housing; a spring normally stressing said carriage toward the exterior of said housing; and means limiting the movement of said carriage by said spring.

4. In a fluid dispensing apparatus, the combination with a hose; of a housing for said hose; bufier means in said housing adapted to yieldingly stress said hose toward the exterior of said housing, including a carriage mounted to reciprocate in said housing; and a spring normally stressing said carriage toward the exterior of said housing.

5. In a fluid dispensing apparatus, the combination with a hose; of a housing for said hose; buffer means in said housing adapted to yieldingly stress said hose toward the exterior of said housing, including a roller, and a spring normally stressing said roller toward the exterior of said housing.
