VALVE-GORE SEATING AND REMOVING MACHINE.

Application filed January 15, 1923. Serial No. 612,872.

To all whom it may concern:

Be it known that l, ITHMER M. Jones, a citizen of the United States, residing at 'laylorville, county of Christian, and State of Illinois, have invented a certain new and useful Improvement in Valve-Core Seating and Removing Machines, of which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.

lfhis invention relates to certain new and useful improvement in valve-core seating and removing machines.

The valve proper of an inflatable tiretube or the like usually includes an internally threaded stem or casing and a valve-' plunger or core, the latter being threadseated for operation within the stem or casing.

My present invention has for its chief objectthe provision ofa relatively simple, readily operated, and efficient machine, whereby the cores or plungers of valves of the type mentioned may be seated in or removed from the valve-stems with convenience, facility, and quickness.

With the above and other objects in view, my invention resides in the novel features of form, construction, arrangement, and combination of parts hereinafter described and afterwards pointed out in the claims.

in the accompanying drawing,

Figure 1 is a side elevational view of a valvccore seating and removing machine embodying my invention; and

Figure 2 is a front view, partly in verti-- cal section, of the machine.

Referring now more in detail and by reference characters to the said drawing, which illustrates a preferred embodiment of my invention, the machine includes a standard or body 1 provided at its lower end with a base-plate 2 adapted for rigid attachment to a table or other place of support. At its upper end, body or standard 1 is formed preferably integrally with a lateral. ar1n3 provided at its free end with spaced socalled bearing-fingers 4: and 5. y

Mounted for rotation upon finger 4;, is a relatively large bevelgear 6 provided with an operating handle or crank 7 and meshing with a smaller bevel-gear 8 fixed upon the upper end of a vertically disposed stub-shaft 9 arranged for rotation in bearing-finger 5,

tation by shaft 9 at its lower-end, is a depending core-engaging and manipulating or actuating tool or bit 10. Suitably attached at one end, as at 11,130 standard-arm 3, is an angular-member or bracket 12 carrying at itsouter, end a substantially U-shaped member 13 embracing the Working end of" tool or bit 10, as also best seen inl igure 2, forpurposes shortly appearing.

Formed upon the base 2- ofstandard 1 in proper vertical alignment with the tool or" bit 10, is a tubular-support l l fora suitablyelongated vertically disposed tubular springhousing 15 preferably permanently closedat its lower end, as at 16. Disposed within housing 15, is'a coiled expansion spring 17, and yieldingly supported by spring 17 and adapted for lengthwise movement relatively to and within housing 15, is the post or pedestal 18 of a preferably circular table 19, a cap-plate 2O fastened to housing 15 and engaging post 18, as seen in Figure. 2, retaining the post 18 and its supported plate 19 in operative relation to the supportingspring 17 and its housing 15.

In use or operation, the inflatable tube is placed upon table 19, as indicated in dotted lines in Figure 2, and its carried stem disposed within the chamber or cavity of member 13, as shown, in operative vertical alignment with tool or bit 10, table 19 conveniently yielding to suitably accommodate and permit proper placement ofthe tube and stem. In seating a core or plunger within the stem, the core is now placed suitably within the stem and engaged by the bit 10, the member 13 facilitating proper co-operative placement of the stem and core. On rotary actuation of the bit 10 by the crank 7 in the proper direction, the core, inturn, will be rotarily actuated and thereby thread-seated for operation within the stem. On the other hand, in. the removal of a core from a stem, the tool 10 being suitably engaged with the core and reversely actuated, the core will be readily unseated for removal. My new machine is simple in form and construction, may be cheaply manufactured, and is exceedingly efficient in the performance of its intended functions.

I am aware that minor changes in the form, construction, arrangement, and combination of the several parts of the machine may be made and substituted for those herein shown anddescribed WltllOl lt departing from .the .nature and principle of any inventlon. I

..,H3,V1ng thus: descr bed my nvention,

What I claim and desire.toisecureby, Letters rotary movement in ,a vertically station-- aryplane above the table for actuating the core ;to bethreadeseated 1n tor removed from the stem meansupon'the standard for rotarily actuating the tool, and spring means yieldingly urging said table toward saidtool.

' 2. A machine for thread seating in .and removing cores from valve stems-including, in combination, a standard, a yielding table upon the-standard for supporting the tube and stem, a tool mounted upon the standard for rotary" movement in a ;vertically stationary plane above th'e table for actuating the-core to lbe thread-seatecLin lor vremoved fromthe-stem,=means upon tl1e standard for rotarily actuating the tool, and arigid member fixed upon the standard and embracing the tool for facilitating co-operative placement ,betweenathe stem and core.

A machine for thread seating in and removing cores from valve stems including,

in combination, a standard, a table mounted for yield ngmovement upon the standard for supporting the tube and stem, an arm projecting laterally from thelstandard, a

vertically disposed shaft mounted upon the varm for lrotary movementin a vertically stationary planeabove the table,a tool carried by said shaft forrotarily actuating the core'tozbe thread-seated in or removedfroni the stem, means upon the standard comprismg a gear .fiXed upon the shaft for vrotarily actuating the tool, and a rigid substantially U-shaped member fixed upon the standard to embrace thetool for facilitating-theseoperative placementof thestem andcore.

In testimony whereofgl have signed my name to this specification.
