4 Claims.
This invention relates to improvements in air chucks of the type used in delivering compressed air or other gases from a supply source. Its objects are to provide a simple, cheap, easily operated and efficient means of delivering compressed gases; to combine with an air chuck, of the character generally employed in filling stations and the like for inflating pneumatic tires, means for releasing air from the chuck independently of the normal air chuck valve releasing means; to effect such releasing action either with or without nozzle means for constricting the path of the gas; also to provide separate nozzle improvements for an air chuck; and generally to effect a strong durable structure which is protected, in any position it may assume, from accidental operation of the valve releasing means- The invention consists in means and combinations suitable for accomplishing the foregoing objects, as explained in the following specification and includes not only the specific embodiments so described but all substantial equivalents thereof within the scope of the appended claims.
In the accompanying drawing:
Fig. 1 is a symmetrical central cross section of my improved air chuck;
Fig. 2 is a view similar to Fig. 1 and illustrates the valve means in an open position;
Fig. 3 is a detailed view of a nozzle member;
Fig. 4 is a cross section taken on the line l4 of Fig. 1.
Fig. 5 is a diagrammatic view illustrating positions taken by the air chuck when not in use;
Fig. 6 is a view in side elevation showing a modification of air nozzle for a. chuck;
Fig. 7 is a front elevation of the nozzle and spring assembly shown in Fig. 6 with the spring partly cut away; and I Fig. 8 is a cross section taken on the longitudinal axis of the nozzle member illustrated in Fig. 6.
Referring more in detail to the drawing, It! indicates a pipe means for delivering a compressed gas such as air therethrough and is threaded at H to engage with a similarly threaded portion The bushing I5 is recessed at its inner side to receive a valve seat I 6 and secure it against the housing l2. The valve seat It loosely supports a valve member H at its under side and an opening l9 of an even further reduced diameter receives therethrough an extended valve portion [8 while the valve itself is maintained loosely adjacent the seat and is preventedfrom, falling away beyond a deflnite'ppint. The opening I! connects with a cylindrical chamber 20 in housing I 2 to comprise a passageway for release of compressed gas. When gas is delivered under pressure from the pipe ID, the valve l1 becomes engaged against the seat It and is maintained by the pressure. However, it no pressure is being delivered the 5 valve may drop away from the seat to only a limited extent since by the construction of the opening I! there results an annular shoulder portion in the housing I2 against which the valve must rest. The chuck [2 has been designed with an enlarged body portion as shown in Figs. 1' and 2 at one end of which is slidably received a plunger 2! having its path of movement intersecting the line of projection of the valve stem portion iii. A head 22 is fixed to the plunger 2! and air pressure maintains the plunger 2| firmly against the gasket 23. It will be noted that valve l1 and chuck face l3 may operate at any time in the conventional manner of being applied over the valve stem of a tire. However, by depressing the head 22, plunger 2| angularly contacts member l1, tending to tip it into a position such as that shown in Fig. 2, which breaks the seal between the plunger and the gasket l6, thereby permitting air to pass through the opening It in th chuck face.
It will noted that portion l8 has been formed with a ball 24 and constricted neck 25. While not limited to such a construction, I may prefer to utilize this or some similar means for providing easier and more positive tipping action of the portion 18 by the plunger 2|. When the mechanism is in the position "shown in Fig. 2, air is released through the chuck independently of the conventional method of depressing the valve I! from the outside. For some purposes, such a releasing means may be satisfactory and greatly desirable, but it"may also be desired to supply the air through a nozzle such as 26 iilustrated in Fig. 3 which is of conventional form and construction, having'its tip comprising a straight cylindrical passageway 21.
When such a nozzle member is desired, I may associate it with the mechanism already described by eiiecting threads 28 on the nozzle 5 member and by forming similarly sized threads 29 on the inside of bushing I5. Such association of the nozzle member with the face of the chuck has been indicated in broken lines in Fig.
1. I may also desire to employ, as well as a conventional valve, a valve design such as that shown in Figs. 1 and 4, in which the outer edge of the valve I 1 may be scalloped as indicated at 30, or otherwise serrated, so that should only a slight tipping of the portion it occur. somewhat 5:
applying nozzle means such as that used on spray guns in which liquid is introduced through the side of the nozzle in the well known manner. and
not considered necessary to be illustrated and described in connection with the present air chuck illustration. The operation of the valve with the head 22 has been facilitated by so arranging the head that the length of tubing and conductor such as it is firmly grasped in the hand and the head 22 readily falls into a position adapted to be operated by the downward pressure of the thumb, which provides a better leverage. At the same time the head is preferably constructed of a size such that it extends beyond the chuck body only a slight distance. This is desirable for the reason that in use, less likelihood of accidental release or depressing of the head and plunger will occur, and to further this effect the chuck I 2 has been formed with a concaved area around that portion through which the head projects.
It is pointed out that air chucks in general, whether used in garages, filling stations, or machine shops, are usually subjected to rough usage and must be sufiiciently durable to withstand pressure of heavy objects and be adapted to falling into various positions without release of the valve. In connection therewith, I have formed the chuck body in somewhat of an elbow shape and placed the plunger in such manner that no matter what position the chuck may be thrown into, it will not come to rest on the head 22 and thereby release or open the valve I'I. Fig. 5 more clearly illustrates the protected arrangement of the plunger head 22 in various positions of the tool. The full line position shows the chuck face down, and the broken line position shows the chuck face up.
With this construction, a strong, durable and simply operated and adjusted air chuck is provided which may be operated in three ways: (a) as a normal chuck for a tire valve; (b) as a source of supplying air in which the valve is released from the inside without a nozzle; and (e) as a source of supplying air with a nozzle. Either one of the latter two operations may be useful in air blasting for various purposes as in cleaning, drying,- and the like.
Figs. 6 to 8 inclusive relate to a modified form of nozzle and releasing means for an air chuck 3i of the conventional order. 32 indicates a mi;- zle member which may be of any desirable shape as for instance the form shown in cross section in Fig. 8. The nozzle may be received on some supporting means as for instance the flat spring 33 shown partly cut away in Fig. 7, and the opening in the nozzle 32 is continued through the flat spring .33 by means of a tubular extension 32a, which may either be a separate element or formed as a part of the nozzle as shown in Fig. 8.
The spring member33 may be resiliently assoagainst by some suitable means as a wing nut 30 and bolt 81.
The flat spring 33 will preferably be bent in' a manner such as that illustrated in Fig. 8 so that the nozzle member 32 and the tubular portion 12a are maintained away from the face of the chuck 8| and the tubular portion is out of contact with the chuck valve. However, when the spring 23 is pressed against the face ot.. the chuck, the tubular member enters into the conventional opening therein, thereby opening the valve and permitting air to pass out through the nozzle 22, with the tubular member 22a acting as a conducting member as well as opening the valve.
A practical and eiilcient means for increasing the field of use of air chucks of the type used in nlling stations is provided by the construction shown, and an eiilcient and easily mounted nozzle means is associated with such a chuck by only one adjustment. Also, the valve opening portion of the nozzle and its tubular portion 32a is extremely positive and may be operated by depressing the spring or by pressing the nozzle directly against the work as for instance a tube to be blown out.
Having thus described my invention, what I claim is: a
