APPARATUS FOR USE IN MAKING SHOES Original Filed Dec. 13/1941 18 I I] I 22 LA.)
Patented Dec. 21, 1943 APPARATUS FOR USE IN MAKING SHOES Sidney J. Finn, Beverly, Mass., assignor to United Shoe Machinery Corporation, Flemington, N. J a corporation of New Jersey Original application December 13, 1941, Serial No.
Divided and this application December 26, 1942, Serial No. 470,189
12 Claims.
This invention relates to apparatus for use in making shoes and particularly to apparatus for use in practising the method disclosed in application Serial No. 422,808, filed December 13, 1941, in my name, of which this application is a division.
In the cement attachment of soles to shoes by pressure-responsive cement, if the forepart of the sole is located with respect to the forepart of the shoe and then the heel partof the sole located with respect to the heel part of the shoe, the shank portion of the sole will bridge across the curve of the shank, and the length of the sole from the ball to the heel-seat will be less than the distance measured along the curve of the shank. Consequently, when the shank portion of the sole is forced against the shank of the shoe, the material of the sole has to stretch in order to equal in length the curve of the shank. This, of course, puts a longitudinal tension on the shank portion of the sole which tends to cause it to pull away from the shank of the shoe, a condition which militates against the production of shoes havingpermanently close shanks.
. The object of this invention is to provide an apparatus for overcoming the above disadvantageous conditions by providing, in the shank portion of the sole, a sufiicient length of material to correspond substantially to the length of the corresponding part of the shoe measured along the curve of the shank.
In attaching soles to shoes with pressureresponsive cement, the forepart is first located with respect to the forepart of the shoe. The shank portion of the sole may then be bent away from the shank portion of the shoe before the heel end of the sole is attached to the heel-seatof the shoe. By the present invention, apparatus is provided to insure that the distance that the sole is separated from the shank will be sufficient to provide a distance measured along the sole which will correspond to, or slightly exceed, the distance measured along the curve of the shank between the respective contact points between the. sole and the shoe. As illustrated, the apparatus comprises a pair of fingers relatively movable heightwise of the shoe and adapted, when in proximity to each other, to be located between the shoe and sole at the shank portion. Means, for example a treadle, is provided for separating the fingers a predetermined amount which may be varied for different shoes.
In the drawing,
Fig. 1 is a side elevation of apparatus embody ing the present invention;
2 is a view similar to Fig. 1, the apparatus being shown in inoperative position; and
Fig. 3 is a plan view of the apparatus shown in Fig. 1.
The illustrated apparatus comprises a pair of fingers I 0, I2 carried respectively by a lever l4 and an arm I 6. The fingers l 0, 12 may, as shown, be right-angle prisms with their longest faces in contact, the right angles being disposed at the top and, bottom. The arm I6 carrying the finger I2 is rigidly mounted or formed as an integral offset from a sleeve [8 fixed to a vertical shaft 20 mounted for rotation in a bearing 22 formed in a bracket having an ear or ears such as 24 adapted to be secured to a suitable fixed support, such, for example, as the left-hand side of the machine, for pressing the shoe and sole together. The shaft 20 is held from upward movement by a washer 26 secured by a screw 23 to the shaft. The lever l4 carrying the finger I0 is pivoted at 30 between ears 32 offset (Fig. 3) from the sleeve 18 which is carried by the shaft 20. Between its ends the lever l4 carries a vertical slideway 34 in which a sliding block 36 is mounted. An adjusting screw 38 is threaded into the upper part of the slideway in position to engage the block 35 and limit its upward movement with respect to the lever I4. To the block 36 is pivoted one end of a link 40. A lever having three arms 42, 44 and 46 is pivoted at 48 to the finger arm IS, the lever arm 42 having ears between which the lower end of the link 40 is pivoted. A pin on the lever arm 46 is connected by a tension spring 50 to a pin on the finger arm 16, the spring holding the link 40 and the arm 42 in the angular position shown in Fig. 2 with the fingers l0, I2 together.
In the bearing 22 is formed a vertical slideway in which is fitted a slide 52 connected at 54 (Fig. 1) to a treadle rod 56. The slide 52 carries a roll 58 which engages an inclined slot 60 in the sleeve l8 so arranged that upward movement of the slide will swing the sleeve and the fingers which it carries about the axis of the shaft 20 from right to left. The upper portion of the slot 60 is vertical and, when the roll reaches this portion of the slot, rotation of the fingers ceases and a lateral projection 62 (Fig. 3) carried by the slide 52 engages a roll 64 on the lever arm 44. Further upward movement of the slide then straightens the toggle formed by the link 40 and the arm 42. The block 36 is thus raised and, after engaging the screw 38, separates the fingers Ill, I2 by swinging the finger lever l4 about its axis 30 a predetermined amount, depending upon the setting of the screw, upward movement of the slide 52 being limited by engagement of the roll 53 with the upper end of the slot 60.
In practising the method of my above-mentioned application, a lasted shoe S (Fig. l) and an outsole O are prepared for cement attachment by coating the overlasted portion of the upper and the marginal portion of the attaching face of the sole, including the heel-seat portion of the shoe and sole, with pressure-responsive cement such as the polymerized chloroprene cement disclosed in United States Letters Patent No. 2,061,296, granted November 16, 1936, upon application of Walter H. Wedger, the cement being allowed to dry until it is in such condition that the shoe and sole will stick together when brought into contact. The operator then locates the forepart of the sole with respect to the forepart of the shoe and presses them together. Then, While holding the shank-and-heel portion of the sole somewhat separated from the shoe, hedepresses a treadle connected with the slide 52, causing it to move upwardly, thus swinging the fingers l0, l2 into position between the shoe and sole. Further movement of the treadle causes the fingers to separate a predetermined amount, depending upon the setting of the screw 38. The rear end of the sole is then pressed against the heel-seat of the shoe, as shown in Fig. 1.
The amount of separation of the fingers is so adjusted that the distance measured along the sole from its point of contact with the shoe at I the ball to the point of contact with the shoe at the heel end will be at least equal to, and may exceed, the distance measured between these points along the shoe bottom. If the length of the shank portion of the sole exceeds the length measured on the shoe against which it is to be laid, the act of forcing the bulged portion of the sole against the shank will place that portion under endwise compression so that it will tend to lie all the more firmly against the shank of the shoe.
The shoe is now ready for treatment by a sole pressing machine having a novel type of pad box which enables the shank portion of the pad to be depressed relatively to the heel part and forepart so that, when a shoe prepared as described is placed upon the pad, the outwardly bulged heel portion will extend into the depression in the pad. The pressure is then applied to the toe and heel,
and finally to the shank portion to force the.
shank portion of the sole into its place against the shank portion of the shoe. A machine for this purpose is disclosed and claimed in an application, Serial No. 470,188, filed December 26, 19%2, in my name.
