SHOE-TURNING MACHINE.

SPECIFICATION forming part of Letters Patent No. 706,038, dated August 5, 1902.

Application filed October 10, 1901. Serial No. 78,152. (No model.)

T at whom it may concern.-

Be it known that I, ANDREW EPPLER, J r., a citizen of the United States, residing at Boston, in the county of Suffolk and State of Mas- 5 sachusetts, have invented certain new and useful Improvements in Shoe-Turning Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled IO in the art to which it appertains to make and use the same.

The presentinvention relates to shoe-turning machines.

Turn-shoes are commonly sewed wrong side I 5 out and after the sewing has been completed are turned right side out, and the machines which perform or assist in performing this operation are called shoe-turning machines. In has been proposed in several machines of the prior artfor example, in the machine of patent to Edgerly, No. 442,770, December 16, 1890--to provide a form, so called, hav ing the general shape of the fore part of a last, and the function of which is to support the fore part of the shoe to be turned, which is placed thereon generally after the heel portion has been turned either by hand or by another machine. In connection with the form above described it has been proposed to provide a turning implement, which in some machines consists of a bent arm, as shown in said Edgerly patent, and in others of another last or form, as shown in patent to Oollyer and Symonds, No. 146,654, January 20, 1870. The 3 5 turningimplement above referred to is so supported and arranged that its inner end engages the toe of the shoe to be turned when said shoe has been placed upon the form and the turning implement brought into operative relation thereto, the body of said implement extending substantially in line with the last. To turn the fore part of a shoe on such a machine after the turning implement has been brought into operative relation to the form, the operator takes hold of the heel portionand by pulling it forward turns the fore part on itself, slipping it off of the form onto the turning implement.

It has been found in practice that when the heel portion of the shoe is pulled forward, as above described, the sole is apt to slip, not bodily, for the turning implement engaging the toe commonly prevents bodily slipping; but the back part is apt to slip forward, causing the sole to bend or buckle outward, the 5 5' result of which is to impede the turning operation and to put a severe straino'n the shoe, which causes the seams to gape or rip and tends to distort and otherwise injure the upper.

The present invention contemplates the provision of a supplemental turning implement which engages the sole back of the toe at the point where. it is liable to buckle and prevents such buckling, said supplemental turning implement being preferably movable With reference to the form, so that its point of engagement can be transferred along the sole as the shoe is being turned.

While, as above stated, the present invention contemplates, broadly, the use of an auxo iliary turning implement with any kind of a form, I prefer to use it with a form the bottom of which is sufficiently recessed to per- 'mit an inward bending of the sole, and I prefer to so arrange the'auxiliary turning implement that it Will not onlyengage and hold the sole, but will force or bend it into the recess in the form. By the arrangement last suggested I give the sole a preliminary bend or break, as it is sometimes called in handturning, which substantially relieves the strain on the upper during the turning operation and makes the operation of the machine approximate more closely to hand methods.

Moreover, the present invention contemplates the provision of an improved form which also tends to relieve the upper of undue strain, and, further, certain improvements in the form and arrangement of rotating head or turret which carries the forms 0 and other detailed improvements, the nature and advantages of which will be readily understood from the following specification. The preferred embodiment of the present invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation, Fig. 2 is a plan, and Figs. 3 and 4 are detail views, partly in section and partly in elevation, showing the form, turning implement, supplemental turning implement, and a part of its actuating mechanism, Fig. 3 showing the supplemental turningimplementretracted and Fig. 4 showing it advanced and engaged with the sole of a shoe on the form.

In the drawings similarletters indicate like parts in the several views.

The machine of the drawingsis provided with a suitable frame, which conveniently consists of a base A and a head B, which are so connected at b that the head B may be adjusted vertically to make the machine convenient fora tall or short operator. This arrangement is similar to that common in sewing-machine and other arts and need not be f nrther described.

Mounted in suitable bearings in the uprights I) b is a rod 0, to which is secured a cross-piece c, rigidly connecting, the rod 0 with a rod 0 the inner end of which is provided with holding means for receiving and holding the turning implement, which, as shown, is the tn rning-iron O. The rods 0 and c and their connecting cross-piece 0 together form a rigid supporting-yoke for the turningiron 0, much like that embodied in the shoeturning machine known to the trade as the MillerShoe-TurningMachine. Thecrosspiece 0 supports a rest 0 for the operator to lean against while turning the shoe, being substantially similar to that of the Miller machine. As in said Miller machine the yoke which carries the turning-iron C may be turned to move said iron into and out of operative relation to the form by turning the rod 0 in its bearings. Means are provided to restrain the rod 0 from rotation when the turning-iron O is in operative relation to a form, which means conveniently consist of a collar 0 fast on shaft 0, and a collar 0 rigidly secured to the upright 17, the collar 0 being provided with an inclined projection which engages a correspondingly-inchned recess in the coller 0 A coiled spring 0 is provided, which surrounds the rod 0 and is interposed between a collar 0 and the upright b. The spring acts to slide the rod 0 through its bearings, said rod being arranged to slide as well as rotate therein and to keep the collars c and c in contact with each other, the arrangement being such that the rod 0 cannot be rotated and the yoke which su pports the turning-iron turned when the iron is in operative position unless sufficient force is applied to overcome the tension of the spring 0 i i. H. H J

The devices last described are not materially different from corresponding devices in said Miller machine and form no part of the present invention. From the head 13 is projected a bracket d, upon which is mounted a rotating head or turret D, provided at d with suitable means for holding a series of forms F. The turret D is not in itself materially different from that embodied in said Miller machine. The bracket d is arranged to slide in suitable vertical ways (not shown) in the head 13 and may be adjusted vertically to bring the form F at a level with the turningiron C and secured in the required position by means of the adj usting-screw d and the clamping-bolt d, which extends through a vertically-elongated bolt-hole in the upright b and is tapped into the bracket cl. It will be noted that the head B forms a central support, from which the yoke which supports the turning implement is projected upon one side and the form-supporting turret upon the opposite side. This arrangement is, so far as I am aware, novel and renders the machine more convenient to operate. The forms Fare also of novel construction, being cut away or recessed at the bottom to permit the sole to be bent inward and at the top to permit the upper to be drawn within the line of the full form-4. e., a form not cut awayat points where the full form would tend to bind. As shown in the drawings, this is accomplished by cutting away all but the marginal portion of that part of the form which corresponds to the ball or tread portion of a last, and thus forms an aperture fin the form extending from a point toward the toe to a point toward the shank. I desire to say in this connection that when used With means for bending in the sole I consider any construction of the bottom of the form which will permit the sole to be so bent. to constitute a recess and to be within the scope of the present invention.

111 the machine of the drawings the auxiliary turning implement His located below the turning-iron O and is arranged to be advanced to cause its working end It to engage the shoe at a point back of the toe and in advance of the working end of the iron 0 and to be retracted as the shoe is turned. As shown, the auxiliary turning implement H is pivotally supported at h by a carriage 773, which is mounted to slide upon the rod 0 which supports the turning-iron C. By pivotally supporting the auxiliary turning implement H, as shown, I provide for a longitudinally-tipping movement thereof, for the purposes hereinafter described. A spring, conveniently the coiled spring h is provided, secured to the carriage k and to the crosspiece a, said spring normally acting to hold the carriage 7L2 in contact with a stop 0 on the rod 0 As shown, the stop 0 is formed by the projecting inner end of a spline c, set

in the rod 0 Upon the spline o is formed a cam c which is engaged by a cam-roll 71', carried by the auxiliary turning implement H, said roll 7L being held against the cam 0 by a spring 0 which bears upon the auxiliary turning implement H upon the opposite side of its fulcrum h As shown, the turning-iron O has at its Working end a downwardly-projecting lip 0 behind which lies the working end of the auxiliary turning implement H when the same is in its retracted position, and the cam 0 isso shaped that when the lever H is advanced its working end It is first depressed to clear the lip 0 and to come under the sole of the shoe to be turned and is then raised to engage the sole and force it into the aperturef in the form. The working end h of the auxiliary turning implement H may conveniently be provided with an antifriction-roller.

The mechanism for moving the carriage 7L2 toward the form to advance the auxiliary turning implement I-I consists of a link it. pivotally connected at to the carriage 7L2 and pivotally connected at 7& to the bent lever 70 fulcrumed at k on a sleeve surrounding the rod 0 and fixedly secured thereto. The lever 7.2 is operated by a treadle k -and suitable connections Zn.

The operation of the machine of the drawings is described as follows: Assuming that the bracket d has been properly adjusted to bring the form F to the level with the turning-iron O, the iron 0 is swung out of the way, a shoe with its heel portion turned is placed upon the form F, and the iron 0 swung back into operative position, substantially as in said Miller machine. When the turningiron 0 has been brought into operative position, as above stated, with its working endin contact with the toe of the shoe to be turned, the operator by pressing down-on the treadle k advances the auxiliary turning implement H until its working end 72. has engaged the sole of the shoe and bent it into the aperture f in the form F. (See Fig. 4.) Still keeping his foot upon the treadle k to hold the auxiliary turning implement H in the position last described, the operator grasps the heel portion of the shoe in the usual manner and pulls it forward, the upper bending on itself and the sole bending over the working end of the auxiliary turning implement. As the turning of the sole progresses the operator by gradually releasing the treadle It? allows the spring 72/ to retract the auxiliary turning implement H, its working end h forming a support, over which the sole is bent and which travels toward the toe. As the upper is being turned the cut-away portion at the upper portion of the form F by affording space into which the double material may be drawn prevents the binding of the upper upon the form.

Having thus described a preferred form of my present invention and the preferred mode of operating the same, I desire to say that I do not consider the same as to its principal features as limited to the construction herein shown and described, since said features are broadly novel, no devices having to my knowledge been provided in the prior art whereby the advantages herein set forth or any of them could be obtained.

I therefore claim, broadly, and desire to secure by Letters Patent 1.
