JAMES E. JACKSON, OF LYNN, MASSACHUSETTS, ASSIG-NOR TO UNITED SHOE MACHINERY COMPANY, OF NEW JERSEY.

PATERSON, NEW JERSEY, A CORPORATION OF MACHINE FOR FINISHING INSOLES.

Application filed September 18, 1911, Serial No. 650,020.

To all whom it may concern:

Be it known that 1, James E. JACKSON, a citizen of the United States, and resident of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Finishing Insoles, of which the following 1s a specification.

The present invention relates to machines for preparing insoles of the Gem type; that is to say, insoles whose edges are slit to form lips which are turned up to receive stitches, each sole being covered with reinforcing material, such as canvas, on the side from which the lip stands up. A perfect insole ,of this type must have the reinforcing ma trial pressed thoroughly-into the angles at the junction of the lip with the sole, otherwise the stitches by which the upper is at tached to the insole will be loose and will permit the upper to pull away from the insole so as to expose the stitches. This looseness of the reinforcing material is a common fault, although attempts have been made to provide machines which will press the reinforcing material snugly about the lip and into the angles.

The present invention provides a machine adapted to press the reinforcing material into the angles and to stretch the material tightly over theupper surface of the sole and over the lip so as to overcome the defect explained. This operation is known commercially as rib tightening and lip hardening.

This invention embodies a number of improved structural features one of which is a jaw carrier on which is mounted a pair of jaws adapted to grip the lip of the insole and move bodily to feed the insole step by step.

Another feature is a work support adapted to cooperate withthe inner lip-engaging jaw to compress the sole behind the lip so as to reduce the thickness of the sole at that point as nearly as possible to the thickness of the margin of the sole outside the lip. The advantage derived from thus compressing the sole occurs when the shoe is undergoing a sewing operation in a machine for attaching the upper to the insole with or without a welt. The curved needle of such Specification of Letters Patent.

Patented Nov. 30, 1915. Renewed March 5, 1914.. Serial No. 822,767.

a machine enters the lip from the outside and emerges at the inner side, the point of the needle being generally caused to enter the lip at its junction with the margin of the sole. The margin of the sole is considerably thinner than that part of the sole lying within the lip, because of the stock which is taken away from the margin to form the lip. Consequently, when the needle passes through the lip it meets a greater thickness of stockbehind the lip and oftentimes passes considerably beyond the lip before emerging from the sole. N ow, therefore, if the sole be compressed at its junction with the inner side of the lip, the needle will more readily emerge at the said junction after passing through the lip, so that all the stitches upon being drawn tight will lie in the angle at the inner side of the lip.

Other features of the invention are illustrated upon the accompanying drawings and hereinafter explained and claimed.

On the drawings, which illustrate one form in which the invention may be embodied: Figure 1 represents a side elevation of the machine. Fig. 2 represents a front elevation of the machine. Fig. 3 represents an elevation, partly in section, of the feed jaws in open position, and the adjacent parts. Fig. 4 represents a rear elevation of the mechanism included in Fig. 3. Fig. 5 represents a side elevation of a lever for changing the length of feed, the elevation being the reverse of that represented by Fig. 1. Fig. 6 represents a top plan view of the lever shown by Fig. 5, and includes other parts in section. Fig. 7 represents a perspective view of a swinging carrier upon which the feed jaws are mounted. Fig. 8 represents an elevation of the lower end of the inner feed jaw. Fig. 9 represents an elevation of the lower end of the outer feed jaw. Fig. 10 represents a portion of an insole before being subjected to the action of the jaws, as shown by Figs. 8 and 9. Fig. 11 represents a section. similar to Fig. 10, showing the results of the operation of the jaws.

The same reference, characters indicate the same parts wherever they occur.

On the drawings the machine isillustrated as having a base 10 and a working head or a cam 27 on the main shaft.

frame 11 provided with suitable bearings for a main power shaft 12. A work support is indicated at 13, and the rib-tightening and feed jaws are indicated at 1% and 15 respectively, the jaw 11, hereinafter termed the outer j aw, being adapted to engage the outer face of the lip and the feather or marginal extension of an insole a, while the jaw 15 is adapted to engage the inner face of the lip and the surface of the sole inclosed by'the lip. One of the jaws is movable relatively to the other for gripping the lip, and both jaws are movable in unison forfeeding the sole step by step.

As :shown by Fig. 7, the jaw 15 which engages the inner side of the lip is carried at the lower end of a carrier 16. The jaw is rigid with relation to the carrier, and in the present instance is an integral part thereof. The upper end of the carrier is bored for the reception of the main shaft 12, whereby the, carrier is adapted to swing as a pendulum about the shaft to impart feeding movementvtothe jaws. The movable jaw 1st is pivotally connected to the carrier by a pivot stud 17, the location of the pivot with relation to the work-engaging faces of the jaw being of especial importance, as hereinafter explained. 'Thejaw 14 is connected by a link 18 with a ph'inger 19 fitted to slide in hearings in the carrier. 11 spring 20 connected to the plunger and to the carrier tends to raise the plunger to open the jaw. The jaw is closed positively by a cam 21 on the shaft 12, the upper end of the plunger 19 being provided with an adjustable abutment 22 for engagement with the cam, said abutment being shown in the form of a setscrew.

Swinging movement is imparted to the carrier to feed the work by an arm 23 aifixed upon a rock shaft 241. The free end of the arm 23 is connected with the carrier by a link .25. An arm 26, also affixed to the rock shaft 24, is arranged to be engaged by The arm 26 is held against the cam by a leaf spring 28, the action of the cam effecting the feeding movement, and the action of the spring effecting the return movement of the carrier. When the machine is operating upon the toe of an insole where the curve is very sharp, it is desirable to shorten the length of the feeding steps, and for this reason the machine is provided with a device for that purpose. This device is shown by Figs. .1, 5 and 6 and comprises an arm 29 having a shoulder 30. The arm 29 is carried by the lever26, being connected thereto by a pivot 31. The cam surface 30 cooperates with a pin or projection 32 (see Fig. 6) projecting from the frame 11. A spring 33 tends to keep the arm 29 raised, and a rod 34: extends downwardly from the free end of the arm andmay be provided with a treadle (not shown). hen the feed cam 27 imparts a feeding movement, the lever 26, together with the arm 29, is moved away from the projection 32, and when the lever 26 is returned by its spring 28 the length of the return movement is determined by the position of the arm 29, the arm 29 in its upper positionbeing adapted to permitmaximum return movement; but when in its lower position, the shoulder engages the projection 32 and cuts short the return movement. The shoulder 30 is preferably beveled, asshown by Fig. (3, so as to avoid positive resistance to downward movement of the arm 29 in case the arm should be depressed whilelying against the projection 32. lVhen the re turn movement of the lever 26 is thus limthat the movement of the plunger 36 is wholly independent of the sleeve 37. An arm 38 is aiiixed to the upper end of the plunger 36, said arm being provided with arod 39 which extends downwardly. (See Fig. 1.) The lower end of the rod 39 is adapted to be engagedbyalevertO, which lever is pivoted at 41' and adapted to be operated by a cam 42 on the shaft 12., The presser-foot is normally held downwardly upon the work support bya spring 43 (see Fig. 2), and is positively raised by the cam 4-2. The rear end of the lever 40 extends beyond the cam 12 and is connected to a rod e4.- which extends downwardly to a treadle (not shown) whereby the presser-foot may be manually raised.

As hereinbefore stated, this invention comprises means for compressing the sole behind the lip to reduce the thicknessoffthe sole at that point as nearly as possible to thethickness of the margin outside the lip. This'compressing operation is effected by causing relative movement of the work support and theinner feed jaw 15 in such manner as to indent the sole a small portion at a time. The word indent as herein used does not imply the well-known operation of indenting the stitches by which an outer sole is attached, but means the compressing of a small portion of the insole at one time and repeating the operation at a series of points to form, as it were, a groove in the insole wherein the thickness of the leather is reduced. So far as the result is material, either of these elements may be moved to- Ward and from the other. In the present instance, thewvork support moved toward the feed jaw to compress the sole, thus utilizingthe shaft 12 as an abutment for re sisting the upward pressure of the work support.

Referring to Fig. 1, the work support is provided with acylindric stem 45. This stem is arranged in a socket formed in a boss 46, the lower end of the stem 45 bearing upon the upper end of a plunger 47. The plunger extends downwardly through the base 10 and is provided with a collar sl-S and surrounded by a spring 49 which normally tends to depress the plunger. A pin 50 aiii ed to the upper end of the plum ger extends outwardly through a slot 51 in the boss 46. (See Figs. 3 and i.) The pin also extends through a slOt 52 in a meme ber 53 which is affixed to the lower end of the sleeve 37 hereinbefore mentioned. The sleeve is mounted to slide vertically in bean ings formed in the frame 11. An arm 5% affixed to the upper end of the sleeve carries a hardened member 55 which engages a cam 56 on the shaft 12. The effects of the cam are to lift the sleeve and thereby lift the work support to press the insole against the jaw 15. The hardened member 55 is adapted to be adjusted to render the compressing movement positive, or to be otherwise adjusted to render the compressing movement yielding. For this purpose the hardened member is provided with a screwthreaded stem 57 which extends through the arm 54: and is provided with check nuts 58. A hollow spring '59 contained in a socket in the arm 54: exerts its tension upon the member 55 to press said member toward the cam. In order to render the action of the cam positive, the check nuts 58 are turned to draw the member 55 tightly against the arm 5-l, thus eliminating the spring 59 as an active element. In order to render the action yielding the check nuts 58 are unscrewed to permit the member 55 to move downwardly with relation to the arm 54. In addition to this change of ad-v justment, the arm 54 is raised slightly with relation to the sleeve 37. This latter adjustment is effected by loosening the set screw 60 by which the arm 5% is affixed to.

the sleeve. When the arm 5st has been raised with relation to the sleeve and the member has been released so as to be subject to the tension of the spring 59, the upward movement of the work support is made yielding. V

The member 53 is connectedwith the pin 50 by a manually operative latch 61. (See Fig, 4). The latch is provided for holding the wor support in operative position, but may be moved to release the work support so that the latter may drop to facilitate the insertion and removal of the work; The

latch is pivotally mounted upon the member 53 by a pivot member 62. A finger 63 formed on the latch has a cam surface 64:, and a slight depression 65 for the reception of the pin 50 when the latch is in working position, as shown by Fig. 4:. At the completion of the operationthe latch may be moved. manually, being provided with a handle for that purpose, to withdraw the finger 63 from under the pin 50. The spring plunger .t J is thereby released so that it may descend and so that the work support may descend with it. \Vhen a new piece of work is placed upon the work support it may be raised to operative position by depressing the handle of the latch, thus causing the cam surface 54 to'engage and raise thepin 50. The latch is held in operative position not only by its weight but by the pin 50 resting in the notch 65.

Referring now to Figs. 1, 8 and 9, the faces 14? and 15 of the feed jaws are formed to stand at an inclination to the sur face of the work supportwhen the jaws are in gripping position. This arrangement of the grip )ing faces bends and sets the lip of the sole inwardly and facilitates the heating out operation, to which the shoe is subsequently subjected, and the folding in of the lip, as well as having other advantages well known to those skilled in the art..

The face 14 of the jaw 14 is adapted to engage the feather or marginal portion of the sole outside the lip, but does not engage such marginal portion until after compression by the inner jaw, because of the reduced thickness of the marginal portion. It will be observed that the pivot 17 about which the jaw 14: swings is so located as to cause both of the faces 14 and l l to recede from the lip and margin respectively when the jaw is opened. In view of this action it is seen that on the reverse movement the two faces engage the reinforcing fabric where it is unsecured, as shown in Fig. 10, before the jaw 14. is finally seated in the outside angle, and in its final inward movement the jaw draws the fabric inwardly from the edge of the sole toward the lip to the position shown in Fig. 11. r

The face 15" at the lower end of the jaw 15 is the face which cooperates with the work support to compress the sole behind the lip. It will be observed that this face is inclined with relation to the surface of the work support, the faces 15 and 15 forming an acute angle. By reason of inclining the face 15 in this manner, the greatest compression of the sole occurs at the junction of the inner side of the lip with the sole. There are two advantages in compressing the sole in this manner: First, the face 1:")? acts as a cam or wedge to draw the sole laterallyso that the point of the jaw will find its way into the crease or angle where the lip joins the sole. In this way the canvas or other reinforcing nine-n11 which extendsfover the lip and over, the sole becomes slightly stretched and tightly forced into the crease. To those skilled in the art it is wen known that the reinforcing material is coated with adhesive material so as to cause it to stick to the sole. Second, the advantage of compressing the sole against the inclined face 15 is to redncethe thickness of the sole most at the point where the greatest redaction is needed in order to facilitate the passage of the needle through the lip The curved line 66 in Fig. 11 represents the cnrvature of a needle such as that nsed in a machine for sewing the ripper to the insole. i

The stem of the work support is free to human the boss 4:6, and the work support is therefore adapted to rotate as the work is fed, thereby facilitating the feeding operation. After an insole has beenplaced in operative. position it is not necessary to guide it while the machine is i'n motion, the feed jaws being adapted to t'urn the work little .by little as it advances, because the lip of the insole remains always between the As fa res'ult of the operation of the ja w l i the reinforcing material, the edge tliereef is drawn back slightly from the edge of' the insole, as slio ivn by, Fig. 11, so that oer thereiiiforcing material ,will not be visible when the iiisole attached to an upper.

It will he recognized by those skilled in the art, from the foiegbing description, that talii features of the invention are not liniitedto 'nsein a machine for ope 'ating on reinforeed i nsoles';
