SHOE-PRESS.

Application filed December 6, 1917.

T 0 all whom it may concern.

Be it; known that I Enema Gorrramo a specification.

This invention relates to shoe-presses used in the manufacture of boots and shoes by uniting the upper with the sole exclusively by the application of a cementing or adhesive substance, the shoe thereby being clamped between conveniently shaped parts of the press, in order to obtain a sure bind ing of the edges of the leather to be re mentcd together. The invention more especially relates to those parts of the press which direettv act. upon the work piece whieh is in the press at the time. and its objcct is to obtain a devitat adapted for an easy and quick operation of the parts thereof.

For this purpose the parts of the press which aroin direct contact with the work piece or shoe are 'adjustabledn several respeets and loosely arranged. so that they can be brought in contactwith a work piece outof the press and inserted and dis iilaced.

therein together with said work piece.

A'- press (it this t'onstltlil-iml presents the advantage that its operative parts may be plaeed upon the work piece. when removed from the press. in which case the eombinztspecification of Letters Patent.

tion of said elciuents is accessible from all.

sides. thus permitting atreatment ot'the work pieee't'or the subsequent pressing operation. whereafterthe united parts'cun be inserted into the press as a whole. (.lther ob jeets and advantages will more fully appeal from the following Slittlfitzlllfill and be pointed out in'the appended claims.

modification of the loose yoke or how of the press.

Similar numerals denote similar parts throughout all figures of the drawing.

Referring to Figs. 1 to 3; a cross-piece 41 ha run; any suitable shape and being adapted to transmit. the pressure of the pressing member 40 on to the shoe to be pressed, is used; itearries at one end a stay or support 4-12 of known construction which-rests upon the tor'e end of the shoe or boot, and carries at its rear end a pressure piece or block 43 provided with a last-pin ll (see Figs. 1' and .3). The said parts 4-2 and 43 are art-ieu lated upon the how 41 by means of hinges and it). resptartively. The support 42 is made of two parts capable of being screwed into one another. so that the length of the said support can be varied and conformed to the height of a last. The pr.. sure block 43 is recessed with a bore receiving a helical spring 49 (Fig. 5). which tangentially bears with its upper extremity against the endt'aee of the how 41 insuch a manner as to have the tendenov to turn the pressure block 43 with the last-pin rigidly fixed thereon. about the hingelti toward the. support 42.

\l'hen the pressure block 43 rests upon the upper face of alast 50. thepiu Hmngagea the usual bore of said last. the fore cnd'of the block 43 directed to the point of the shoe. projeets or laps over the instep-bl n-k 49 of the last 50 and holds said instep-block \Yhcn the support 42 ears upon the toreend ot' the instep-block 4 as may be better seen in Fig. l. owing to the inclination and curvature of the upper portion of the instep-bloele the same. is not likely to be moved out of its propel position. that is to say. be forced upwardly 'or stretched apart from the last. thereby altering the shape'of the lasted upper.

The lower (Xtltllllt, l 0f the"screw-spindle .40 having handles 9 or the like. is guided in which is movable therein lengthwise and may easily be withdrawn therefrom. hen

the spindle acts upon the how. the latter will be displaced downwardly in the slot 47. but. be prevented from lateral oscillation.

The rest or bed of the. sole of the shoe to be pressed may have any suitable. form,

i. 22., may be a bed plate having the average shape of the shoe and containing a liner 56 of yielding material in a recess of ITS upper face. A cushion having a liquid or a semiplastic filling may however be used as a bed for the shoe, as well as a self-adjusting support 5, shown in Fig. 4, which has been fully described in my specification, Serial No. 150,853.

The beds and 5, respectively, can be shifted lengthwise in unison withthe bows 41 and 41 respectively, being guided with downwardly projecting pairs of feet or standards 2]. and 21, respectively, on arib 22 of a supporting-table 21, Fig. 1, or the corresponding support shown in Fig. 4. The bed plate 55 (Fig. 1) is further held on a set screw 23 provided in a supportingtable 24, and which can engage several recesses of the under side of the bed plate and is adjustable vertically, so that the bed plate 55 which is tiltable about the feet 21, may be given any desired inclination. The table 24 on its part is mounted upon a screw-bolt 5 which is received in a vertical bore of the lower arm 7 of the press and engaged in corresponding female threads of a hand Wheel 26, by the rotation of which, as will be obvious, the bed plate can be adjusted in any required height below the head 53 inconformity with the height of 'the last used at the time being. This will allow of the insertion into the press, of the bed plate together with the shoe and the how 41, which latter is at the same time introduced into the guide slot 47, whereafter a small stroke of the \pressanember 40 will be suflicient to press the shoe upon the bed.

The press heretofore described is operated and acts as follows: The press bow 41. is applied outofthe press to the work piece, that is to say, the shoe and the last therein,

y engaging its pin 44 into the correspond ing bore of the last and placing the support 42 on the fore part of the shoe, as shown in Fig. 1, when the power of the spring 49 will. automatically clamp the bow on to the work piece and secure the said parts to one another, so that they maybe handled as one piece. The edges of theupper and the sole.

may now be prepared for sticking by suitably applying the adhesive thereto; this can be done without any danger of the bow alter 1 'ing its position relatively to the work piece.

The shoe thus made ready operation 1s then,

for the. pressing placed with its sole upon the bed and adjusted thereon. in. order to be fully in contact therewith in its entire area. The assembled parts can now be inserted into the press a whole from the front of the press, whereby the -bed is brought to engage the rib 22, .while the bow enters the slot 47 and is advanced therein .as far as required for the desired distribution ofthe pressure of the spindle com the fore and rear ends of the shoe, the spindle being able to work upon any part of the back face of the bow. Generally the bed. must be shifted in accordance therewith. Besides the preceding adjustment of the work piece with respect to the bow and the bed, which adjustment had been made out of the press, no further displacement is necessary when placed in the press; on the contrary the sure guiding of the press-momhers 41 and 55 has the effect to prevent the work piece from any il'ladvertent shifting 0H its proper position during pressing. Finished the sticking. the shoe together with the bow and the bed can be withdrawn out off the press in the same manner and then separated from the said press men'ibers. The method presents great advantages in the manufacture, the work pieces can be treated out of the press by one or more boys who deliver the aggregate, composed of bed, work piece, and bow. to the operator of the press. lit is understood, that owing to the elements of the aggregate being already in contact with one another, only a small downward stroke of the press spindle 40 is required to the shoe firmly upon the bed plate 55. Of course, the bed may remain in the press, if its face exactly corresponds to the sole, so that an adjustment of the shoe thereon out of the press can be. dispensed with.

If a self-adjusting bed 5 isused (Fig. 4:), the bearing fate of which automatically conforms itself to the curvature of the sole, there is no necessity to remove it from the press; it can be adjustably secured by means of a set screw 28' movable in a slot 29' of the supporting arm 7' of the press. Only the united bow and work piece are manipulated separately out of the press and put together upon the bed fast in the press.

The modified bow 41, shown in F ig. t has a stay 42 and an inclined prismatic guide 57 adapted to regulate the position of the said stay. Furthermore, the spring 49 is not housed in a bore but its extremities are merely attached to the press-block 43"anu the how 41, respectively.

The fast arrangement of the bed 5 upon the press makes it desirable to dispose the; means for regulating the height of the stroke upon the upper arm 6. To this end a screw threaded sleeve 20 receiving the spindle 40, is vertically movable in the head 53'. details of such construction are well knownin the art. In this modification the guide 47 is connected with the screw spindle 40 and will therefore be moved up and down with it.
