HENRY B. HARRISON, OF WORCESTER, MASSACHUSETTS, ASSIGNOR, BY MESNE AS- SIGNMENTS, T0 DAVID I. ROGOW, OF NEW YORK, N. Y.

FOLDING-MACHINE.

To all whom it may concer/n:

Be it known that I, HENRY B. HARRISON, a citizen of the United States, and a resident of lVorcester, Massachusetts, have invented certain new and useful Improvements in Folding-Machines, of which the following is a specification, accompanied by drawings.

This invention relates t0 folding machines, but more particularly to folding machines for folding the margin of the facing material over the edges of a sole, and pressing said material upon the sole. The machine may, however, be used for any folding or pressing operations to which it may be found applicable, and is not limited in its uses to folding the edges of the facing material upon the soles.

The objects of the invention are to improve upon the construction of such niachines, simplify the parts and increase the efficiency, while enabling a greater amount.- of work to be done in a given time t-han heretofore, at less expense.

To these ends the invention consists of a machine for carrying out the above objects, embodying the features of construction, combinations of elements and arrangement of parts, having the general mode of operation substantially as hereinafter fully described and claimed in this specification and shown in the accompanying drawings.4

Figure l is a side elevation of the machine partly in section; Fig. 2 is a plan view with the frame partly broken away; Fig. 3 is a front elevation of the machine; Fig. et is a perspective view of the folding mechanism; Fig. 5 is a perspective view of one guide member; Fig. 6 is a perspective view of another guide member; and Fig. 7 is a perspective view of the wiper.

Referring to the drawings, A vrepresents the frame of the machine and B represents the bed or table to receive the work. In the drawing on the plan view, Fig. 2, the position of a sole C for a slipper or other article of foot wear is indicated, which sole is pass* ing through the machine, while the edges D of the facing material E are being folded and pressed upon the sole. The edges of the facing material E are first preferably provided with mucilage F so that said material will adhere to the sole.

A suitable guide preferably formed in sections or members for a purpose hereinafter Specification of Letters Patent.

to appear, enables the edges D of the facing material E to be accurately folded over upon the sole C. The sections of the guide are shown in perspective views in Figs. 5 and 6, in this instance there being two sections or members, of a suitable conformation and construction to carry out the objects of the invention. These guide members H and J, which together form the guide, in this instance extend longitudinally of the machine and transversely to the line of movement of work, so that the edges of the sole may be pressed against the end of the guide to turn up the edges D of the facing material E.

A wiper G preferably in the form of a disk is mounted adjacent the guide members and connected to be automatically reciprocat-ed horizontally over the edges of the sole in order to turn or fold the edges D 0f the facing material E down upon the sole. A suit-able hammer or presser in the form of a vertically reciprocating rod K is provided with a presser foot L and mounted adjacent the wiper Gr. Means are provided for vertically reciprocating the presser and presser foot in order to press the facing material upon the sole and cause it to adhere to the sole. Any suitable means hereinafter to be described may be provided for actuating the wiper and the presser and said actuating means are so constructed and timed in their operations that the downward stroke of the presser foot L is completed as the wiper G completes its forward stroke. By this means the presser foot L presses upon the work-as the wiper G starts t0 recede on its back stroke, thus holding the work in position as the wiper recedes.

The construction of the guide members H and J, the wiper G and the presser K and presser foot L and the relative arrangement and location of said parts may be Varied as desired, but I have illustrated in the drawings a suitable construction and arrangement of the part-s which has been found to act satisfactorily and well for the purposes for which the machine is intended. The outer guide H in this instance comprises a bar of metal having a curved shoulder O and a reduced portion m of substantially the thickness of the bed or table B. The inner guidel J is preferably wider than the outer guide H and is also provided with the curved shoulder P normally in line with the shoulder O of the guide member ll. The guide member J is also provided with the reduced portion Q and the overlying` flange l?. adapted to lie on top of the tabl-e B. The guide member J is also preferably provided with the recessed portion S into which extends the wiping edge T of the wiper Gf. The wiper is preferably in the form of a disk cut away or flattened at one side U and having a stepped construction, the high portion V of which is provided with the curved wiping edge T. rlhe low portion lV of the disk preferably extends over th-e guide members H and J. The wiper G as shown is provided with the boss X on its under side through which extends the pivot pin Y into the bed of the machine. A compensating spring Z preferably provided between the head of the pivot pin and the top of the wiper in order to provide for inequalities in the work. A connecting rod stud c. is provided upon the wiper to which connected the connecting rod o adapted to be actuated from a source of power in order to reciprocate the wiper horizontally about the pivot pin Y. The parts are so constructed that the wiper is reciprocated through substantially an angle of JOO indicated by the dotted lines c and (Z.

The guide members ll and J as shown are mounted side by side between the table B and the clamping member e. A guide cap f as shown holds the rear portions of the guide members in position. The guide members may slide longitudinally of their leiigth beneath the guide cap f and suitable springs g press the guide members forward. rlfhe edge of the sole is pressed against the shoulders O and l) and owing to the fact that the guide members are independently7 movable, the shoulders conform to the curve of the end of the sole and accurately turn up the edges D of t-he facing material E. At the instep and heel of the sole7 the guide members H and J would obviously assume different relative positions owing to the difference in the curve of the edge of the sole at these two portions. Both guide members may recede at the same time or one may recede while the other is moving forward and vice versa so that at all times the edge of the sole abuts against a turning surface at the shoulders O and P. This is one of the important features of my invention and owing to the construction and arrangement of the guide members, l am enabled to do more rapid work and more accurate work on my machine than heretofore.

The wiper, continually reciprocating hori zontally7 forces the uptuii'ned edge l) of the facing material E down upon the pasted edge of the sole, and the presser foot continually stamps the down-pressed edge upon the sole to maintain it in position on the. finished article. The combined action of the guide members H and J and the wiper (l turns and folds the edge l) of the facing material and crimps it to conform to the curve of the sole. The presser foot L flattens the crimped portions of the facing ina,- terial and produces a neat finish for the article.

The presser K in the form of a red is preferably provided with a hollow end 7L in which is provided a compression spring The presser foot li is in the forni of a cap extending over the lower end of the presser rod K and through the slots in the presser foot and through an aperture in the presser rod passed the pin o, so that the presser foot li may have vertical play on the presser rod.

Any suitable driving connections may be provided for actuating the wiper and the presser. in this instance the frame i of the machine being provided with the horizontal arm j) having the vertical guide bearings y for the presser rod K. Mounted in bearings r and s in the frame is the driving shaft t provided with the combined balance and driving wheel u through which power is applied as by means of a belt. @n the outer end of the driving shaft t provided the crank disk 2 having the crank pin to which is connected the pitman il pivoted at its lower end. to the pin. 5 adjustably mounted on the presser rod K by means of the sleeve G and screws 7. il suitable step in the form of a collar 9 may be clamped below the collar 6 upon the rod K.

rlhe driving shaft T may be provided with suitable bevel gear 8 meshing with bevel gear l() on the vertical shaft 11 mounted in the frame and provided with a bevel gear 12 at its lower end. Said bevel gear l2 meshes with the bevel gear 13 mounted on the horizontal shaft lst carried in the bean ings 15 and provided with a second bevel gear 1G. ln the vertical bearing 17 is mount ed a vertical shaft 1S having the bevel gear lf) at its lower end meshing with the bevel gear lo while at its upper end is in'ovided the crank disk Q0 having the crank pin 2l to which is pivoted the crank shaft B connected to the wiper G.

rlhe operation of the machine is substantially as follows: Power is applied to the driving wheel n, thereby rotating the shaft t, which rotary motion .is translated into a reciprocating vertical motion through the crank 9. and pitman e in order to vertically reciprocate the presser and presser foot li. Rotary motion is also transmitted through the vertical shaft 1l, horizontal shaft Mr and shortvertical shaft 18 to the crank Q0, which is translated into a horizontal reciprocating motion through the crank o in order to horizontally reciprocate the wiper rlhe machine is run at high speed and the wiper and presser foot are reciprocated rapidly.y

The soles to be operated upon are fed transversely through the machine, preferably by hand, although automatic machinery could be provided for this purpose. The edges of the soles are pressed against the shoulders O and P of the guide members H and J and as the sole is turned the guide members conform to the curve of the edge and turn up the edge D of the facing material E. The wiper G continually folds the edge D down upon the sole and the presser foo-t continually stamps the material upon the sole.

lVhile the guide members are in themselves an important feature of this invention, the Wiper is also an important feature, for by means of the wiper the facing material is continually and accurately folded down upon the soles. The edges of the facing material E are also crimped to conform to the curve of the edges of the sole and since the parts are so timed in operation as to move the presser foot down upo-n the sole as the wiper completes its forward stroke, it will be seen that there is no tendency to move the sole as the wiper recedes, since it is held in position upon the table by the pressure of the presser foot. The presser foot then releases the sole, in order that it may be fed forward to bring a new portion of the material opposite the wiper. It has been found that the output of completed soles has been greatly increased by the combination of the guide members, the wiper and the presser foot, as constructed, arranged and assembled in relation to each other in this machine.
