It will be noted adapted to be held in any predetermined posithat when the articulate plate is in position in tion through the medium of a locking pin Ill one-of the compartments I5, the sole portion 25 which is engageable in any one of a series of rethereof is normally supported by the toe piece 45 cesses II, formed in the side of the block. The 20 of the base, above rib I1, and has superimblock in the present instance, is shown to be of posed thereon the pad 23. The pad 23 in the polygonal configuration in cross-section to propresent instance consists of a rubber cushion, vide a series of fiat surfaces, each of which is the top of which is shaped to generally conform adapted for the reception of a pressing unit gento a shoe sole and arch. In practice, the shoe is 5 erally designated I2. mounted on the pad or cushion 23, preferably in Each of the pressing units consists of a base the manner shown in Figs. 2 and 4 of the draw- I3, provided with ears I4, through which securings. ing means are engageable for connecting the The shoe presser forminga part of each unit 66 base to' the block 9. The base is divided into comprises a last, the body portion 300i whichis detachably engaged to an articulate base generends of the

plates

33 and 35 uniteand are recessed to receive a bar 31, circular in cross-section, which is formed on the rear terminal of the front part of the articulate base 3|. The body portion of the last 30 has a pawl 38, fixedly mounted on one side thereof which is adapted to coact with the teeth 34. The opposite side of the body portion 30 of the last is provided with a finger 39 arranged in the path of movement of the abutment lug 36. The fastening means 32 may be adjusted to permit relative movement of the rear part of the base 3|. When the desired angularity is obtained, pressure causes the pawl 38 to be locked into engagement. with the teeth 34, as shown in Fig. 5 of the drawings. movement of the rear portion of the base 3| is limited by reason of the abutment lug 36 and finger 39. The top of the body portion 30 of the last is provided with a recess 40 which is adapted for the reception of the lower terminal of a clamping screw 4|.

It will be noted'from the drawings that one of the clamping screws 4| overhangs each of the compartments l5 of the base l3 and for the purpose of supporting the screws, I provide a bearing bar 42 for each unit. The bearing bar is carried by the unit base l3 through the medium of shafts or rods'43, the ends of which are screw threaded. The inner ends of the shafts or rods are engaged with the bosses 2|, while the outer ends engage the bearing bar 42. For the purpose of feeding the screws 4|, I provide, in the present instance a hand wheel 44.

In using this device, it is apparent that an articulate plate 22 is mounted in each of the compartmentsl5 and the pad or cushion 23 then mounted thereon. The shoe, indicated in' the drawings at S, is superimposed on the pad, as il-' lustrated to advantage in Fig. 2, after which the shoe presser or last is inserted in the shoe. It is of of said base being accomplished in a manner already described. The feed screw is then fed against the body portion 30 of the last through rotation of the wheel 44, thereby flexing the shoe into the pad 23. This pressure is transferred to the articulate plate 22, urging the proximate ends of its digits or parts upwardly and correspondingly exerting pressure on the pad or cushion 23 and urging the latter against all parts of the sole without danger of slippage of the latter. Each unit is adapted for the reception of one pair of shoes and all of the feed screws 4| may be successively operated by the same removable wheel 44. After the various units of the pressing machine have been filled, the shoes are permitted to stand for a predetermined time until positive adherence of the sole with the shoe upper is ef- Downwardiected, after which the shoes are removed from I the units in a manifest manner.

It is of course, understood that although I have shown the units as being associated with the block 9 in order to provide a multi-unit machine, the units are also used individually and when so used, the supporting ribs l6, l1 and I8 provide a substantial foundation for the unit. The units therefore, may be used either singly or in multiple without any change'whatsoeverin the structures thereof.

It is to be understood that the pad or cushion 23 is preferably made of solid rubber, which how Although I have herein described the present I preferred form of my invention, it is nevertheless to be understood that various changes may be made in the construction, proportion and arrangement of parts, within the scope of the claims appended hereto.
