VALVE BOX.

- Application filed may 20, 1922, Serial No. 562350 1. Renewed March is, 1925.

This invention relates to a box for containing valve insides and aims to provide certain improvements therein. Certain types of valve insides, as now 6 constructed, comprise a shell formed at its lower end with a valve seat and having a screw-threaded portion at the top with an intermediate packing washer for making a tight joint with the valve casing. The valve 1 proper is connected with a pin which passes through the shell, and a spring is provided within the shell for normally maintaining the valve proper in a position where it engages the seat. In this type of-valve, the constant pressure of the valve proper against its seat injures the rubber gasket with which the valve proper is provided, so that when the valve inside is placed in po- 'sition in the valve casing it is very apt to leak. v

According to the present invention I provide a box or container for such valve insides which will maintain the valve proper away from its seat during the period prior to the actual insertion of the inside in the tire valve. The invention also comprises certain other features of improvement which will be'hereinafter more fully described- I In the drawings wherein I have shown one embodiment of the present invention Figure .1,is a plan view of a box or container provided by the present invention and showing a group of valve insides contained therein. a portion of the cover of the box being broken away.

Fig. 6 is a sectional View of a modified form of cover.

Fig. 7 is a similarview angles to Fig. .6. I

Referring to the drawings, let A indicate 50 the box as a whole, which isshown as comprising a body I?) and a cover C. Preferably the bottom of the box is-corrugated as shown at D so asto form recesses or sockets for receiving thevarious valves insides. E. In the illustration given, the corrugations run across the box so that the valve insides occupy positions which are transverse to the taken at right box, or, in other words, transverse to the direction of movement ofthe cover C.

Each of the valve insides illustrated com.- prises a valve seat member or shell which includes a seat F, a screw-threaded portion G, and a packing H. Between the packing and the screw-threaded portion the diameter of the shell otthe valve. inside is necessarily reduced so as to leave a part ofless diameter belo-wthe threaded portion. J is the valve proper which is mounted upon a. pin K, the latter having acollar beneath which is arranged aspring which normally holds the valve proper against the. seat F, the seat actually contacting with a. rubber gasket mounted on the seating face of the valve proper J. According to the present invention, means areprovided, for holding one or more of such valve insides (or others in which similar conditions are present) with the. valve. proper away from the seat and the seating face of the valve'check member free from engagement with any other part so that the seat will make no indentations or grooves inthe rubber gasket during I the period in which such valves are in stock or in the possessionof the consumer. v

I To this end I provide means to produce a relative movement between the shells of the valve insides and the pins K (and, hence, the valves proper J In the specific construction shown I provide the cover G With amember or abutment L which is adapted to engage the lower side of the threaded portion G, and forcethe latter toward that side of the box, which is adjacent to the ends of the pins K. The pins Kcontact with the side of the box which-constitutes a second abutment for the valves so that they are prevented from further movementwhilethe shells are moved laterally until the valves proper separate from their. seats. The part L is shown in Figures 1% as being a separate stripsolderedto the under side of the coverand having a rounded end M which contacts with the lower sides of the screwthreaded portions and successively moves the latter. into the required position. This is easily accomplished because the insides are held against movement either lengthwiseof the box ,or downwardly away from the cover. a

In Figs. .6 and 7 the member L is formed by depressing, the box cover longitudinally as shown atlj. 1 v

Preferably the box at one end is cut away as shown at N in Fig. 5 so as to permit the sides and move the seats away from the member L to slide therethrough. The opposite end is preferably uncut so that it is not possible to apply the cover from the other end of the box.

lVhile I have shown and described one form of the invention, it will be understood that I do not wish to be limited thereto since various changes may be made therein without departing from the spirit of the in vention. It is not necessary that the cover should slide transversely of the valve members, nor is it necessary that the pins should be held stationary and the seats moved, since these may be changed without departing from the invention.

What I claim is:

l. A box adapted to contain one or more valve insides comprising a receptaclehaving means for engaging parts of said insides to separate the valve proper of each inside from its seat, said means including means carried by the box cover.

2. A box adapted to contain one or more valve insides comprising a receptacle having means for engagingparts of said insides to separate the valve-proper of each inside from its seat, said means including a part of the cover adapted to move one part of the valve inside and thereby to cause such separation.

3. A box adapted to contain valve insides comprising a receptacle having means for contacting with th pins of the valve inside and with the seat members thereof, one of said means being adapted to move relatively to the other and thereby produce a longitudinal movement of said pins and seat members.

4. A box adapted to contain valve insides having recesses for receiving the valve insides arranged transversely of the box, and a cover having means for successively moving the seats away from the valves proper.

5. A box adapted to contain valve insides having recesses for receiving the valve insides arranged transversely of the box, and a cover having means for successively moving the seats away from the valves proper, said means comprising a longitudinally arranged member designed to contact with the under side of the sides of the threaded portions ofsaid valve insides.

6. A box adapted to contain valve insides having recesses for receiving the valve insides arranged transversely of the box, and a cover having means for successively moving the seats away from the valves proper, said means'comprising a longitudinally ar ranged member designed to contact with the under side of the sides of the threaded portions of said valve insides, said means comprising a strip of metal carried on the under side of the cover and having a wedging fend adapted to contact with the under sides of the screw-threaded portions of the valve invalves proper.

7.
