IMPROVEMNT IN -TILORS PRESSING-MAGEINE.

@ige Sdgrmrlc nimh it in tlges triers tant mit limiting part of tigt same T() ALL WHOM IT MAY CONCERNz' f Be it'lrnown that I, JOSEPH W. TIIORP, of Hillsborough Bridge, in the county of Hillsborough`,;and' Statejoff- `New Hampshire, have invented a new and useful Improvement in-Talors Pressing-Machines; andI do herebyv declare that the following is 'a full and exact description thereof, reference being hadv to the `'2t-ceon'ipztnyin'g drawings, and 'to the letters of reference marked thereon. In the accompanying drawings-'- Figure l is a top or birds-eye view of my machine. Figure 2 is a side view orelevation of the same.l

Figure 3 is an end vien' of the machine. y A Figure 4 is a vertical section of the press-iron and its spindle or shank, showing also the sleeve, and socketjoint for operating the-same. A i

Figure 5 is a detached horizontal section of the collar or nut, forming part of the hinge of the crane or swinging arm. f

Figure 6 is a modified view ofthe cam and handle detached from the press-iron. Figure 7 is an inclined ratchet-standard, 'for supporting the press-board. My` invention consists, first, `in an improvedarrangement for giving a. universal jointto the press-iron sup- In the construction of my improvement in pressing-machines, thecbe-d-platmwith the standards B-and M, may be cast in one piece, in order to hold the main hinge of the crane at one end of the machine in fixed relation tothe attachment of the press-board at the other end ofthe machine. i

The crane or arm C is strongly hinged to the .main frame or standard B, by two large sockets itt'edto bolt on shaft T. Between the socketsl of this hinge is o. well-tted collar, L, iig. 2, provided with a thumb-screw, V, and also hushed bytwo slightly-movable plates, a, fig. 5, against one of which said thumb-screw works in fixing -the collar, andthus supporting the c'rane or arm C at any desiredheight upon the bolt or shaft T.

The hinge between the arms C and D is also very strong, and works closely.

At the distal extremity of the arm D, the socket or `holder E is `attached by a wrist-joint, iig.V 3, provided with a screwstop, D thus giving the socketarotarymotion in the'arm. This socket husa face-plate, and also a cavity of. peculiar sha-pe, fig. 4, forming, with the sleeve F,Aa ball-andsocket joint, `limited by the spindle of the press-iron about to be described. l

The press-iron basa rigid spindle, J, well ttedto and'sliding in the sleeve I". A This spindle is pivotcd lo the handle I by a.pin, K, passing through the sleeve, and working up and downfinslots therein..

The sleeve F may be connected to the handle 'and to the spindle byjmeans oftwolevers H, figs. 2 and 4,

or by two cams, figs. 6 and'S, cast together or rigidly connected by bar c, iig. V8. The latter modification gives less play than the levers H, and also allows the handle I to slide in or out, as'. shown in red and black lines, iig, 6, and thus increase or diminish the leverage os the handle at pleasure. g i. p By this arrangement, aslight pressure of the hand upon handle I brings the force of an elbow-iever upon the spindle of the press-iron, and thus enables the workman, without weariness, to employ any desirable amount of pressure upon hiswork.

The heater j, fig. 4, when too hot, is suspended in the chamber of the press-iron by means of pins z, and Ais not allowed to touch the faceplate of the press-iron, that-:preventing the excessive heat of the h'eater'from burning the goods.

One end ofthe press-board is slightly held or hinged to the rigid cap N, insuch manner thatthe other end of the press-hoard may swing horizontally." The cap N is adjustable upon the firm standard M, and is 'fixed by means of set-screw O, working in a Agroove in the standard M. This cap-may also `be provided, with a ratchet', to fit another ratchet on the standard M, as seen in iig. 7. i I i l f i 17,934

vThe other end of the pressfhoardrests upon :m adjustable prop or folding-jack, P; one foot of which rests in notches Q of the bed-plate, Whilst the other foot rests upon the ratchet-har P. i L

This ratchet-bar r'ests in a groove, and one end of it bears against a piece of rnbbexg-e, iig. 1, dotted red lin'es,so that the bnr, ,under strong pressurefrom the jack P, may slide a littlein the groove, and thus prevent lcutting` ortearing the goods when the press-iron comes unexpectedly in contact with a seam, fold, or other unobserved obstruetion.v i y y I also sometimes employ an adjustable standard, W, fig. 7, having a piece of India rubber, Y, instead of 'the folding-jack and ratchet-bai'.

I do not confine my' invention to the precise form oi` bed-p'late andlother devices above described. The

platte itself may be' cast' in two or more pieces, und lrigidly bolted or otherwise fastened together, and other' changes of construction may be adoptedas experience may indicate, so long as the machine is practically the same, En' substantially'the sume.

Neither do I here claim any ofthe features contained in former patents. Y Y

Having thus fully described thy invention, WhatI claim, and desire tolsecure by Letters Patent oi the United States, is-

1. The arrangement of lthe socket E, the sleeve F, and thespindle J, with.' thepress-ix-on and its adjusting handle, substantially as set foith. f" 4 2. lSupporting th-e heater ata distance 'from-the'face-plate of the press-iron, by means substantially.

described, and for the purpose specified.

' 3. The arrangementof the ndjustable handle a and cm a with the spindle Jand press-iron, i'qi' the purpose substantially as set forth.

4. The u'bber or elastic bearing ea1ranged in'combinntionwith thejack P, substantially as set forth. JOSEPH W. .THORR Witnesses: y GHAs. H." GRIFFIN, C. W.BALDW1N
