Application filed May 8, 1911. Serial No. 625,797.

To all whom it may concern:

Be it known that l, Mrnns P. FILLING- IIAM, a citizen of the United States, residing at Ansonia. in the county of New Haven and State o1 (onnccticut, have invented a new and useful Improvement in Vulcaniaing-li resses; and l do hereby decl-are the following. when taken in connection with the accompanying drawings and the letters ci". reference marked thereon. to be a t'ull, clear, and exact. description of the same7 and which said drawings constitute part of this specification, and representa in-` Figure 1 a side view of a press constructed in accordance with my invention. F ig. 2 a sectional view of' the same with the press tank closed and the table in a depressed position. 3 a similar View with the press tank lowered and the table raised Wit-h the cap supported above it. Fig. t a top View showing the cap in its locked 'position with relation to the tie-rods. Fig. 5 a plan view of the head and cover. Fig. 6 a sectional view ot' the ram cylinder showing a top view of the piston thereon. Fig. 7 a vertical sectional view of the piston. Fig. 8 a sectional Fig. 9 a plan view of the head formed with. an elliptical opening. Fig. 10 a plan view of an elliptical cover therefor. Fig. 11 shows two hars pivoted together and adapted to be used a substitute forthe cover shown in Fig. 10.

This invention relates to a vulcanizing press of the type in which hydraulic pres sure is enzployed and in Which rubber products may be vulcanized, and particularly a press 'in whichtires toin automobiles and otherv vehicles may be .vulcanized; the object of the invention being a simple construction which facilitates the charging and emptying of the pressgrsid in which the necessary power is obtained with the minimum amount of strain on the mechanism; and the invention' consists in the construction hereinparticularly recited in In carrying out my invention, I employ a press tank 2 of suitable size which is adapted to move' vertically on a ram cylinder 3 which cylinder passes through a piston-box l and is supported by a base 5.y Around the 'upper end of the tank 2 is a head 6 which is connected vwith the piston-box 4 by four tie-rods 7.- The upper end of the rain cyl- ,ends of the tierods 7,

Aformed integral with inder 3 forms a table support 8 upon which a table 9 rests, and this table is mountedat the upper end of a ram 10 which extends downward into the rain cylinder to which water is admitted through a port 11 near the base 5. ln the head 6 is a central opening 12, and in the edge of the opening are a series of notches 13 more or less in number. Through the opening a cover '14 may be inserted the cover being formed with outwardly projecting fingers 15 corresponding in position to the notches 13 so that the cover may be passed through the head7 and when passed through may be turned so that the lingers 15 engage with the edge of the cover between the notches 18. Resting upon the head is a cap 16 which is formed with four holes 17 of sufficient size to allow the cap to pass over the nuts 18 on the upper and opening into these holes 17 are slots 19 which permit the cap to be rotated slight-ly'so as to -pass between the nuts 18 to firmly interlock the cap with the head. connected to the under face of the cap 1G by screws 20 passing upward through the cover andinto the cap so that the cover may have a slight vertical movement with respect to the cap which will be turned with it and so that when the cap is turned to interlock with the nuts 18 the cover will be turned to lock with the head (i. To support the cover attach to each of the tie-rods 7 a bracket 21, and the cover isformed with four downwardly extending fingers 22 in the lower part of which rollers 23 are mounted and adapted to ride on the brackets. One of the brackets 24, however, will be formed with a rack 25 and the roller 2G adjacent thereto will he formed as a pinion to engage with the rack and is rigidly secured to a short shaft 27 to the outer end of which is fixed a hand-wheel 28 and so that by turning the hand-wheel thc cap will be caused to rotate. Preferably and as herein shown, the cap will be provided with asuspension hook 29 b which the cap may be supported from any convenient point as will hereinafter appear.

0n the ram cylinder within the pistonhox f1 is a: piston vwhich consists of a ring 30 resting at its lower end on a collar 31 the ram ,cylinder 3 which is also formed with an annular lip 32 above the collar which lip is formed with notches 33 to receive bolts 34 t-he heads of Preferably the cover 14 will be which rest between the lip 32 and the collar 31, the bolts extending up through the ring 30, and this is held in place by a removable collar35 formed with the round holes 36 adapted to set over -the nuts 37 on the bolts 34, and with slots 38 opening from said holes so that if the removable collar is slightly turned it will be interloeked with the nuts. The removable collar will also be provided with perforations 39 which when the collar is turned to clear the nuts 37, will register with threaded holes 40 into which screw eyes may be turned and by which the ring` may be lifted out of the p1s ton-box, it being understood that the holes in the rin through which the bolts pass will besu "ciently large to clear the nuts 37.

In the bottom of lthe piston-box is a port 41 for the admission of water; and 1n the top of the box is a port 42, the first entering below the piston, and the other above it. The ends of the piston-boX will be closed by covers 43, 44, and these covers as well as the bottom of the press tank will be provided with a stuffing box 45 of usual form. Between the head and the cap, I arrange a packing-ring ,46, between'the table and the t table-support a packing-ring 47, andaround the ring 30 I insert two leather packings 48.

The tank 2 may be surrounded by a jacket 49 into which steam may be admitted so as to vulcanize by dry process.

To load the press, the cap 16 is turned so as to clear the nuts 18, and this turning of the cap turns the cover 14 so as to disengage it from the head 6. Water is then admitted through the port 41 into the pisy ton-box below the piston, and this depresses the piston-box. drawing the press tank downward, and it is depressed until the table 9 is exposed at the top of the tank. Mold boxes 50 are then placed upon the table, one on the top of the other if a number are to be inserted; and when the desired number -of molds are placed upon the table the tank is raised by admitting water through the port 42 above the piston and letting water escape through the port 41 below the piston so as to lift the piston-box and raise the press-tank. The .cover` and the cap are then restored to place. If there is then a space between the upper mold and the cover, the ram 10 will be'raised by admitting the water through the port .11 so as to crowd the molds up against the cover and hold the cover up against the under face of the head. Tater will then again be admitted through the port 4l drawing the press tank downward, and forcing the cover to the top of the uppermost mold, which molds will be compressed between the cover and the head with a force equal to the weight of the tankl and press box in addition vto vthe hydraulic pressure. Steam is Jthen admitted to the press tank in the usual way'through the pipe 51 to vuleanize thef articles in the press. When properly cured the cap and cover are againremoved|` ano the press depressed to permit the molds to be readily removed. It `will be noted that this construction permits the mold to be inserted into the top of the press tanker transferred from a suitable platform directly to the table as the table may be moved up or down independent of the press tank.

Instead of connecting the eover 14 with theoap 16, it may be formed independent thereof, and the opening in the head may be elliptical to receive an elliptical cover 52. By turning this cover, it is readily inserted through the head and turned so that its edges engage with the underface of the.

head, or instead of forming the cover as in the form of a 'disk or 4plate it may be in the form oftwo bars 53 and 54 which are pivoted together so that they may be turned to permit the bars to be inserted through the hole in the head, and then turned at right angles to engage with the under face of the head. f
