useful Improvements in Plural-Part Molds,

of which the following is a specification.

My present invention'relates to improvements in vulcanizing apparatus designed for the repair of rubber foot wearand aims to provide a simple, economical, durable and efficient equipment designed to enable foot wear of various shapes to be neatly and expeditiously repaired. 1

The invention includes the novel features of construction and arrangement and combination of parts hereinafter described and defined by the appended claims, an embodiment of the invention being illustrated in the accompanying drawings, in wh1ch:-

Figure 1 is a front elevation of the apparatus.

Fig. 2 is an elevation at right angles to Fig. l.

Fig. 3 is an enlarged sectlonal detail of the dome or head.

Figs. 4:, 5 and 6 are details of the exterior parts of the means for holding the boot or shoe while vulcanizing the sole. I

Figs. 7, 8 and 9 are detail vlews of the horn and plates carried thereby.

Referring by reference characters to this drawing the numeral 1 designates a standard for supporting equipment which may be held in vertical position by any suitable base such as the feet or legsl as shown.

' This standard is hollow and is designed act as a fuel reservoir for containing liquid fuel, which may be supplied to the burner 2 by compressed air which may be forced into the upper part of the reservoir above the fuel level either by a hand pump or any other convenient source (not shown).- it

filling pipe and funnel 8 is provided for introducing fuel into the standard.

Above the burner is located a holler 3 of any suital'ile type designed to supply steam standard and boiler. The boiler is preferably provided with a water gage glass 5, a-

iilling pipe and funnel 6, and a pressure gage 7.

Secured to the top of the standard is a the various parts of the.

head dome or member 9 which carries the vulcanizing'; members hereinafter described and. which alsoserves as a steam collecting and return space, the steam. from the horns returning-into this space, and, with any water of, condensation bein boiler by 'pipe 10, provi ed with a cut-oil valve 10. The head is provided on one side with a plurality of openings 9 two being shown in the drawings as a convenient memher, into which are designed to be inserted the inner ends of vulcanizing horns 11. The horns are provided with flanges 11 fittin returned to the corresponding rabbets in the side of the hea I and the horns are detachablyheld in position by clamping plates 12 secured tothe head by tap screws or bolts 13, the clamping plates having integral sleeves or flanges 12 which embrace the sides of the horns and increase the strength and rigidity of the connection.

The openings 9 and corresponding part s ofthe horns are made round so thatthehorns ma be turned on their ,horizontal axes to bring the foot portions at any angle.

Projecting from the opposite side of the head is a soling plate or table it havin a suitably curved uppersurface beneath which is a steam chamber 15 to which steam from the boiler is supplied by a pipe 16. I prefer to lead the steam to the horns from this steam space as in this manner T can supply steam to the horns without interfering with the ready removal thereof, and to this end I provide a pipe 17 leading from the steam space directly across the head 9 and axially into each horn, each pipe being provided with a cut oil valve 18 having a stem projecting through the top of the head where it carries a suitable operating handle, this providing means for cutting ofi the steam supply in changing horns. .Tt is desirable" that the steam pipes 17 should extend clear into the toe portions of the horns as shown in dotted lines, Fig. 1 and to provide for using shorter horns for difl'erent characters of foot wear each pipe is made with a removable pipe portion 1 detachably connected with the main portion by a detachable coupling 17 of any approved type' To secure the requisite pressure upon the portion of the foot wear being repaired or vulcanized, I

provide the following instrumentalities.

30 of the arms 21. This shaft is provided with a crank handle 23 by means of which, after Supported from a suitable collar 18 on the standard are a pair of parallel bracket arms 19 preferably round in cross section which lie directly beneath the horns and have upwardly curved outer portions 19; The arms 19 have transverse openings 19 through which is passed and slidably held a horizontal bar 20. Associated with each right of Fig. 2 or the bar 20 as shown on the left of Fig. 2, according to the position of the last and foot wear.

band 22'.

These band pulling arms comprise each a curved portion 21 20 having at the extreme end'lugs supporting a bolt or pin 21 which serves as a means -for attachment of the end of a pressure The arms are provided with" a widened outportion above the threaded shank which has a central opening or passage through which the band is'passed and attached to or wound about a shaft or spindle 23 journaled' in suitable bearing lug or portions 21 the band has been adjusted over the part to be vulcanized, it can be wound. on the- I movement.

shaft to secure the requisite pressure, Pawl and ratchet means indicated at 24 is provided to hold" the shaft against reverse The threaded portion of'each arm 21 is 'provided with a wing nut 25 enabling vertical adj ustm'ent of the arm-with relation to number. When'the band carrying a' is I to be applied the curved part of bracket or member 20 is located-beneath the arm: 19 or the rod 20 with'the band overlyin the boot or shoe, in which position it wil be self-supporting, and thereafter the band tightened to the desired degree as above described.

The table 14: is designed for acting on the sole of the boot or shoe and to'this end has its upper surface suitably curved or concaved as shown, and in conjunction-- with this I use sole vulcanizing plates 26 adapted to rest on said curved surface and be heated thereby. I These sole plates 26 have an upper surface designedjto conform to the surface of the sole to be repaired or replaced, and are provided with a plurality. of mar 'nal pins or projections 26 designed to be etachably and interchangeably engaged by the lower ends ofthe tension members or straps '2'Zwhich are-connected at their upper ends to. a bracket member 28 slidably carried on the horizontal portion 29 of the horn or leg last 29' and locked sure to a desired in any desired position thereon by lock screw 28*.

This horn or leg last is shaped at its lower end to project forwardly into the toe portion of the boot or shoeas indicated at 29 where it is provided withremovable and changeable yielding means for bearing against the insole. Such means preferably comprises a plurality of superimposed flexible plates 30, 30 and 30 of graduated size, the desired resiliency of the edges being secured by notching the edges as indicated at a. The plates are'secured to the under face of the portion 29 by means of bolts,

the plates being preferably provided with elongated slots 6 having enlarged portions 6' designed to permit the passage of the 'bolt heads and enabling the plates to be locked on the last or horn by a longitudinal movement which brings the heads of the bolts over the narrower portions of the openings.

By using a plurality of superimposed re-f silient plates I get a maximum of resistance for large articles of foot wear when all the plates are used which may be successively reduced forsmaller articles by the successive removal of the outer plates.

-It'is some times found desirable to sup port the vulcanizing outfit hereinbeforedescribed from a wall or.connect it thereto, and to this end I provide the head or dome with a laterally extending arm 31 provided with a plate 31 designed to be bolted to a wall or other stationary vertical member. Having thus described my invention what I;claim is: p
