' lpplication filed-March 2,

To all whom it may concern: I

Be it known that 1, JOHN ARTHUR, a citizen of the United States, residing at New Woodstock, in the county'of Madison and State of New York, have invented certain new and useful Improvements in Rubber-Shoe-Vulcanizing Machines; and I do declare. the following, to be a full, clear, and exact description of the invention, such as will enable others skilled in the} art to which it'appertains ,to make and'use'the same; r f

' This invention relates to an improved vulcanizin g machine for use in connection with rubber shoes and boots, and one object of the invention is to provide an improved outfit of the character described in:

eluding an "improved shoe or boot holding or supporting pedestal and also an "improved 1 clamp holding device so constructed that a steam box maybe clamped into'tight engagement with the sole portion of a shoe or a pressure band drawn upwardly to hold a patch in tight engagement with the top portion of a boot placed upon the pedestal.

Another object of the invention is to so construct the clamp holding ring that the clamp may be set at the desired angle trans versely of the boot and further so con-- structedthat the holder may be swung longitudinally of the boot and secured in the set position. v a Another object of the inventionvisfto so construct .the device that it m'aybesupported from a wall where it willtake up a small amount of room.

Another objector the invention-is to provide a device of the character described which will be easy to operate and" further.

This improved outfit is :for juse'in connec tion with rubber shoes and boots" for applying solesand heels;v and for applying patches to the rubber shoes or boots'and is provided with a steam pipe 1 providedwith couplings: 2 and 3 at its ends and-with a coupling 4: intermediate its length, the coupling 4 being provided with an inlet intermediate its length and normally iclosedfby a removable plug'5 so that if desired,'a steam boiler or line," not shown; may be connected with the inlet of the coupling '4: when the plug 5 isremoved. The couplings 2 and 3will also be open at their lower ends Patented se a.- 13,1921.

and provided with removable closures so: i

that if desired; a steam line 6-may be connected with one of these couplings for supplying steam from a suitable-source of'supply. Pedestals? and 8 which are holloware i connected with the upper ends- 0f the couplings 2 and 3 and are suitably shaped and relatively short head 10 forfitt'inginto the heel portion of the boot and the pedestal 8 having :its upper end portion formed into an elongated head 11 for'fitting into the toe portion of the boot. When applying-a sole or making repairs to the sole of a bootg'a steambox 12 0f the proper size is made use of, this'steam box having a handle 13 and having an inlet carrying a nipple l4; so; that a flexible steam pipe 15 'may beconnected with'the steam box 12. 'This steam pipe 15 is connected with the valve 15 f aIldrlt tous e the steam" box'12, it is simply necessar'y to open'the valve and steam will1 pass' from he coupling 4 through the valve 16 and pipe '15 into the steam-box. 3 5 f "Bra'ckets16 and 17' are connected with'the supportingboard 18 which will be secured to the wall by suitable fasteners and these brackets are provided with clamping plates 16? and 17' so that the'pedes'tals 7 "and 8 may be firmlygripped and thus the pedes' talS ld in an"operative' position. The

' Willbe readily seen that when it is'd'esired bracket 16 has its forward end portion extended upwardly to provide a post 19 having abearinghea'd 19" at its upper end and the bracket 17 has its end portion extended upwardly to provide a binding post 20. The clamp supporting ring 21 shown in Fig. 6 will be connected with the bearing head 19' of the arm 19 by means of a releasable pivot bolt which passes through the head 19 and arms 23 of the ring. It will thus be seen that by releasing the bolt 22 the ring may be tilted to the desired position and releasably but securely held in this position by tightening-the bolt. This ring is provided with a slot-24 which extends circumferentiallyof the ring and is adapted to receive the threaded stem 25 of the clamp as shown in Fig. 5. A hearing 26 is provided for this threaded stem 25 and a washer 27 and lock-nut 28 have been mounted upon the stem above the ring 21. so that the stemvinay be secured in a set position after the clamp, has been tightened. It should be noted that the stem is provided at its lower end with a substantially spherical head 29which fits into a socket 30 carried by the steam box 12 and further that a plate 31 which carries hooks 32'is loosely mounted, upon the stem and rests upon the head 29. 7

In connection with the pedestal 7, there has been provided a yoke 33 having a bearing in its cross-head through which passes the stem 34 of a clamp as shown in Figs 1 and 3. This clam is provided with a plate 35 having a swive connection with the stem and this plate is adapted to engage the heel of the boot when the heel is being vulcanized in place. This yoke 33 straddles the pedestal and is pivotally mountedby pivot screws 36 which fit into suitable threaded openings formed in the bracket 17 and clamping plate 17'. It will thus be seen that this machine is so constructed that the yoke 33 as well as the ring 21 may be tilted to a' desired posit on and securely held in the adjusted posi- 131011. It will be further noted that the heel or sole may be firmly held in place while the vulcanizin'g is being accomplished as shown inFigs. 1, 2', and 3.

When this improved device is in use, it is set up as shown and the source of steam supply connected either with the inlet of the COllPllIlgA: or with one of the couplings 2 or 3. Y If a heel-is to be vulcanized in place, the rubber boot will be put in place as indicated in F 1g, 3 with the heel put in place and clamped down intight engagement with the boot by rotating the stem 34 to bring the plate 35. into tight engagement with the heel. The pedestal 7 is heated by the steam and I the vulcanizing will be accomplished. If it s desired'to have the boot'drawn forwardly to prevent any danger of it slipping rearwardly, ..a strip similar to a fitrip of bandage may be placed about the boot and upstanding arm 20 and thus the boot will be prevented from having any tendency whatever toward moving rearwardly.

If a sole is tobevulcanized upon the toe portion of the boot, the boot will be put in place as shown in Fig. 2 with the extended head of the pedestal 8 extending upinto the toe portion of the boot. A steam box 12 of the proper size will be put in place and tightly clamped by turning ethe stem 25 to formed of heavy fabric but which may be formed of any suitable material is passed about the toe portion of the boot as shown in Fig. 41 with its end portions engaged by the hooks 32 of the plate 31. The stem 25 can then be turned so that itwill move out;: wardly and thus apply pressure which will hold the patch in place. It is of course understood that when the apparatus is in use, the yoke 33 or the ring 21 will be set at the proper angle and" secured by tightening of the bolt 22 or screws 36. I

A structure has th us been provided by means of which soles, heels and patches. can be easily andquickly a plied to rubber shoes or boots and vulcanize into place.
