,Fi 13 is a to 'plan view of the device as 'il ustrated in ig. 1, certain parts being omitted; and

Fig. 14 is an end View, on a reduced scale, of the rear end of the head of the machine, certain parts being omitted.

As herein embodied, my invention concel sists of -a base member 15 which has connectedC thereto an arm or horn 16,.and a head 17, the head being p-ivotally--connected to the base at 18 in order that the pressing elements 19 and 20, and presser foot 21 can be movedaway from the Working or top surface 22 of the arm 16, for the insertion of workto be pressed, said work being inor roller 19, and pressing element or roller 20, are walls 2d, 2d ofthe bifurcated portion of the head 17,- said bifurcated portion being indicated by 25. The pivoted end of head 17 is also bifurcated at 26 to permit of the installment of the mechanism to omrate rollers 19 and 20 as well as other elementsto be described. During a pressing. operation, rollers 19 and 20 will bel operated, step by step, inv a rotary direction by means of an eccentric 27 on shaft 28 carried by the' walls 29 of the biurcated end 26 of the head- 17. The eccentric 27 carries a strap 30 having a rod 31 connected to an arm32 on shaft 33 which is rotatably supported Aby walls 29 and carries atene of its ends an arm 34. rllhe arm 34: has connected' thereto one end of a link 35 the forward end of said link being connected to a rock arm 36 on hollow trunnion 37 for the pressing roller 19 (see Fig. 12). Roller 19 carries a ratchet -38 engaged by pawl 39 on arm pivotally supported by the sidel 36. 'lo 'rock-arm 36 is also connected onees \in Fig. 5, the rollers 20 are separated and are rotatably connect@ by a clutch device, indicated by 45 in Fig. 5. Both the rollers 2O are rotatable u n the trlmnion d2 which isv non-rotatable in this instance). When shaft 28 is rotated, by means of the handwheel d6 or otherwise=(see Fig. 13) arms 36 and 41 will be rocked, whereby rollers 19 and 20 will be rotated in the direction `of the arrows in Fig-(.1. 'lhe .rotary motion of the rollers will be intermittent, which Yis obvious. intermediate its ends, link 40 engages the arm 47 on fa shaft 48 which also carries another arm 49.- 'lhe arm 49 has connected thereto one lend of a link 50 which at its lower end is Aconnected to a squeezing frame 51 carrying a sponge 52. The

squeezing frame 51 consists of a yoke member 53 having pivotally connected thereto at 54 a rackA 55 which supports the sponge 52'.

' dicated by 60, the other Wall being inclined .'-pressed. Whenthe frame 51 is raised up- .wardly, the rack 55 will move away from yas indicated by 61.

rlhe yoke 53 bears against the vertical wall and the rack 55 against the angular wall. During the operation of the rollers 19 and 20, -arm 47, shaft 48A and arm 49 will be rocked, wherebyvllrame 51 will be raised and lowered. en frame 51 is lowered (it being indicated in its normal position in Fig. 1), the' rack 55 will be forced toward the yoke 53, thereby squeezing the sponge 52, whereby water will be forced out of the sponge '(the' sponge being maintained wet during a pressing operation) and onto the oods belng" pressed,` or rather the seam eing the yoke 53, allovyring the sponge to expand and absorb more water.4 The water for the sponge is drawn from a tank 62 (Fig. 1), carried by the head 17. The water from the tank 62 passes through a duct 63, Y

hollow trunnion 37, for .the roller 1.9, thence through a duct 64 having a spout 65 located over the sponge The' ilow of water through the trunnion 37 prevents same from' becoming heated to an extent that would cause the roller 19 to stick. The roller 19 is heated b an electrical resista-nce coil 66 carried y a block of insulation 67 mounted within a casin 68 lined by insulating material 69. The lilock 67 lits over the elongated hub 70 on roller 19. The casing 68 does not come into contact with the roller 19. The casing will be held stationary by a bracket 71 which is fastened to the wall 24 of the head 17 (see Figs. 5' and 6). rlhe bracket 71 carries a socket 72 to receive a plugwhich is connected by a cable to a. source of electrical supply. The socket 72 will connected to coil-66 by line wires 7 3 and 74.

Water will be poured into tank 62 through a suitable spout 75. 'lc www with 52. rllhe 'duct 63 includes a valve to control the flow of the water..

and also rock-arms 82 and 83. The rocky arm 82 carries a pawl 84 engaging ratchet 80, and rock-arm 83 a pawl 85 engaging ratchet 81. The arms 82 and 83 are connected by a link 86 which extends beyond arm 82 and. is connected to a link 87 which atits opposite end is connected to an arm 88 carried by a shaft 89 mounted in the walls of the base 15. The shaft 89 carries a second arm 90 connected by a link 91 to a strap 92 for an eccentric 93 on shaft 28. When shaft 28 is actuated to operate rollers 19 and 20, rollers 76 and 77 will be likewise operated in unison therewith. v.

Durlng the o eration of rollers 19, 20, 76 andv77, feed ro 1ers 94 and 95 will be 5also operated to v 20, 7 6 and 77. The feed rollers are carried by a shaft 96- carrying a ratchet 97 engaged a pawl 98 on an arm 99 also carriedby shaft 96. The arm 99 is connected by a link 100 to the extension 101 of arm 83 on yshaft 79; hence, 77 are operated, feed rollers 94 and 95 will also operate to feed the' goods to the pressing rollers. The feed rollers 94 and 95 ccoperate with the presser-foot 21. In other words, the presser-foot acts to hold the goods in contact with the knurled surface of the feed rollers, a spring 102 actingmtlo force the presser foot downwardly. e presser-foot 21 is carried by a. vertically movable post 103 suported by a bracket'104 carried by the vhead of Athe machine. The spring 102 surrounds the post 103 upon a collar 105 carried by said post. upper end of post 103 carries a head 106 en aged by the slotted outer end of a lever 107 pivoted to a bracket 108 carried by the ide-frame 109 mounted on head 17 The inner end of lever 107 bears against an arm 110 of a bell crank lever 111 pivoted to bracket 112 carried by head 17. The other arm 113 of lever 111 is connected to one end of a link 114 extending backwardly and attached at its rear end to a lever arm 115, loosely mounted on shaft 33. The lever arm `115 has associated therewith a second arm 116 connected by a link 117 to an arm 118 carried by la rock-shaft 119 mounted on the base 15. The rock shaft 119 carries a lever 120 which acts to raise the pnesserdootv 2l and also move head 17 upon its pivot 18 to raise rollers 19, 20 off the goods or away from the work-plate toremove goods which have been pressed or for the positioning of goods to be pressed. To rock the head 17 upon its pivot 18, ing a slot 122 at its lower end engaging a pin 123 carried by arm 118 (Fig. 1). 'llhe when rollers 19, 20, 76 and.

and bears The l provide a link 121 hav-- .amasar upper vend of lipkv 121 is connected to a bracket 124 carried by head 17. The presser foot 21 may be raised .by operating lever 120 slightly, at which time pin 123 will move longitudinally of slot 122 without operating link 121. 'llo swing the head upon its pivot 18, lever 120 will be depressed sufficiently to cause pin 123 to contact with bottom wall of slot 122. A continued movement of lever 120 will result in raising the outer end of head 17 to raise rollers 19 and 20 off the goods or away from the workplate 22. 'lo maintain lever 120 in raised position, ll provide a spring 125 which is secured at one end to bracket 124 and at the other end to the lever arm 118.

rlhe trunnion 42 for rollers 20 is supported by a frame 128 slidably mounted in slots 129 in head 17. The upper end of frame 128 engages slots 129 in guide-frame 109.

vThe frame 128 carries posts 130, each post carrying a spring 131 which at one end bears against frame 128 and at the otherend against adjust-able nipples 132. The tension of the springs 131 can be, raised byadjusting the nipples 132. The springs 131 act to force rollers 120 against the goods during a pressing operation.

To adjust the working pressure of roller 19, ll provide springs 133, eachspring loeing carried by a post 134 extending .upwardly from base 15 (Fig. 1). lEach post 134 is threaded at 135 and carries, at its threaded portion, a nut 136; one end of each spring 133 bears against a nut 136 and the other end against a collar 137 carried by each post. Each post carries a second collar 138 bearing against the up r surface of the adjacent portion of the ead 17. The posts 134 arerotatable and carry handles 139. When posts 134 are rotated, nuts 136 will move up or down, according to direction of rotation, whereby the tension of ,springs 133 will be increased or decreased.

To prevent rotation of the nuts, ll provide each nut with a pin 140 enging a slot 141 in the plate 142 located at the 'rear of head 17.

llo press a seam, the head 17 will be raised by operating lever 120, after which the goods, should it be a sleeve, will be slipped over the arm 16, the seam portion of the sleeve being positioned in line with the presser foot 21, as indicated in Fig. 7. -After the goods have been positioned, the head will be lowered, causing the presser foot to force the goods against the feed rollers'94 and 95, the seam members being separated,

vas indicated by 143 and 144 in lFig. 7, to

roller 20.

ainst t 1n practice, the roller 19 ywill be forced against a seam by greater pressure than Roller 20 acts ,to datten the spread seam members while roller 19 presses.
