SHOE-MACHINE.

Specification of Letters Patent.

Patented May 23, 1916.

Application filed July 2, 1912. Serial No. 707,221.

To ail whom it may concern:

Be it known that I, LOUIS M. BROWN, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Shoe-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to shoe machines and particularly to a machine for imprinting or otherwise making marks of reference upon soles, insoles or other pieces of material which go to make up a shoe.

In the manufacture of shoes it is usual first to tack an insole to the bottom of the last, to assemble an upper upon the last, and then to pull over the toe portion of the upper and tack it temporarily to the insole at a few Widely separated points, particularly at the toe and at the ends of the tip seam. As the bottom of the insole is perfectly plain, however, and there are no other marks to aid the operator in positioning the upper, it is diflicult for him to ascertain whether or not the edge of the tip at the two sides of the forepart of the last has been brought to the proper positions longitudinally of the last edge by the pulling-over operation. I t is desirable to have the length of the tip vary according to the size of the shoe and it is impossible to determine by the eye the proper length of tip for a particular size of shoe. It is also quite important that the edge of the tip. or the tip seam, shall be straight and shall lie in a direction substantially perpendicular to the longitudinal median line of the shoe or shall bear a definite predetermined angular relation thereto.

It is the object of the present invention to provide means for so marking the sole that the above operation can be performed with ease, accuracv and uniformity.

As an important feature of the means is provided for accurately positioning the sole in definite relation to a fixed line of the machine, together with means acting along that line for imprinting the line upon the sole. As herein shown, the line extends transversely across the forepart of the sole in a direction substantially perpendicular to the longitudinal median invention,

line of the sole and is used by the operator to enable him to position the tip line accurately with reference thereto.

As a further feature of the invention the marking means is mounted for movement longitudinally of the shoe sole into and out of position over the sole and is also mounted for movement vertically into and out of contact with the sole. As herein shown these movements take place simultaneously, the end of the inward movement over the sole being substantially coincident with the end of the vertical movement of the marker against the sole. It is to be understood, however, that these movements of the marker may be executed successively or may overlap to a greater or less extent.

As another feature of the invention the marker is mounted adjustably on its carrier so that the angle which the marked line makes with the longitudinal median line of the sole may be varied at will.

It is also a feature of the invention that the marking die is discontinuous and is composed of a number of sections each yieldingly mounted so that a substantially continuous line may be imprinted upon a somewhat irregular surface.

A further important feature of the invention relates to the adjustment of the gages to position the sole for the operation of the marker. The distance of the tip line from the end of the toe varies with the length and size of the sole in a substantially fixed ratio to that length. It is desirable, therefore, that means he provided for positioning the sole i rrespectively of its length so that the portion of the sole upon which the line or mark corresponding in position to the tip line is to be impressed should be autouiatieally brought into coincidence with a fixed line of the machine, that line corresponding in horizontal location with the line to be imprinted by the marking means. Preferably and as herein shown, the gage which contacts with the heel end of the sole and the gage which contacts with the toe end of the sole are connected for opposite movement in a ratio corresponding to the difference in the total length of successive sizes of soles to the dilferenee in length from the tip line to the toe end of the soles. By this arrangement when the heel gage is moved inwardly a certain distance corresponding substantially to the difierence in length of successive sizes of soles, the toe gage will also be moved inwardly a 'less distance which corresponds substantially to the dilference in length of the toe tip in successive sizes of shoes.

The length of the tip of a given size of one style of shoe may not be the same as that of the same size of another style of shoe. Means is therefore provided for adjusting the gages initially with reference to the fixed line of the machine at which the tip line mark is made to suit the length of tips of the particular style of shoe being treated. The ratio of the length of tips of successive sizes is the same for all styles and hence when once set for the given style the gages are moved in the proper ratio for all sizes of that style. To provide for making necessary style adjustments, means permitting relative movement of the parts is provided between the heel gage and the slide through which its movement is communicated proportionally to the toe gage.

It is also a feature of this invention that the machine is set into operation by the introduction of the insole into proper position to be marked. To effect this the lever which trips the clutch is located under the sole when the latter is in position to be operated upon and is adapted to be actuated by downward pressure upon the insole by the hand of the operator. In this way the introduction of the insole into the machine, and the flattening of it out into position to be marked, automatically starts the machine to perform the marking operation.

Another feature of the invention relates to the means for removing the sole from the machine after the marking operation. As shown, means is provided for lifting the sole from the table on which it rests and depositing it on edge at one side of the machine, this operation taking place automatically after the action of the marking means upon the sole. These and other features of the invention, including various novel constructions and combinations of parts, will appear more fully from the following detailed description, when taken in connection with the accompanying drawings, and from the appended claims.

In the drawings,-Figure 1 represents a side elevation of a machine embodying the invention; Fig. 2 is a sectional plan view taken on the line 2-2, Fig. 1; Fig. 3 is a plan view of the parts above the line 2-2,Fig. 1.

The frame or casing which forms the base of the machine is indicated by the numeral 2 and in this frame is journaled the shaft l which carries the pulley wheel 6 to which power is applied to operate the machine. The upper portion of the casing is extended laterally to form a table upon which the sole is laid for the marking operation.

To position the sole on the table centering and thumb nut 18.

stops or gages 1O, 12 are arranged on the table and spaced apart so as to engage the ends of a sole placed between them. The gage 10 is mounted on a slide guided in a slideway ll in the top of the table in which it is held in adjusted position by a screw 16 The opposite gage 12 for the toe of the sole is similarly mounted on a slide 20 for adjustment in the table longitudinally of the sole. To provide for the automatic adjustment of the gage 12 in proportion to the adjustment of the gage 10,

the slide upon which the gage 10 is mounted is provided with an oifset which is adjustably secured at 15 to a slide 22 which extends lengthwise of the machine flush with the surface of the table and at its rear end is provided with an offset having a downwardly facing rack 23, Fig. 1, which engages a gear 2% on a shaft 26 journalcd in the frame of the machine. The shaft 26 also carries a pinion 28 which engages rack teeth formed on the upper face of a slide 30 formed with an upwardly extending abutment 32 that is rigidly connected with the slide 20 carrying the toe gage 12. The ratio between the gear 2 L and the pinion 28 is such that as the gage 10 is adjusted for different lengths of sole, movement will be communicated to the gage 12 to so position it as to bring the tip line a-b of the sole into coincidence with a fixed plane of the machine, namely, the plane in which the markers 56 are moved vertically in imprint the tip line upon the sole. That is. when the gage 10 is adjusted a distance substantially equal to the difference in lengths of successive sizes of soles the gage 12 will be automatically adjusted in the proper direction a distance equal substantially to the difierence in lengths of successive sizes of tips. Means comprising an adjustable connection between the gage 10 and the slide bar 22 is provided by which the gages may be set mutually to bring the tip line of the particular style of sole being treated into coincidence with the fixed line of the machine at which the mark is made. When set for one sole of a given style the gages will be moved in a fixed ratio to locate automatically the tip line of all sizes of that style.

The marking HIBCllitlllSlll with which the machine is provided makes a line across the outer face of the sole at the portion where the edge of the tip should come when the upper is lasted over it. When this line is provided it is very easy for the laster to see whether or not the upper has been properly pulled to bring the tip seam or tip edge to the proper point on each side of the shoe and also serves as a point of reference for the superintendent or inspector in keeping a check on the workman and enables him to insist on a superior grade of work. The marking means is carried on a yoke 50 which straddles the table and is pivoted at its lower end to an operating lever 52 by a rod 49. On the cross bar 51 of the yoke a marker is pivotally mounted at 54. The marker is composed of a number of yieldingly held dies or markers 56 which are first inked by an ink roll 58 and are then brought in contact with the sole to form a line across the forepart, arr-b, Fig. 2. The marker may be adjusted about the pivot 54. by suitable means (shown as a slot and set screw connection of the marker with the cross-bar of the yoke) to vary the angle which the tip line makes with the longitudinal median line of the sole. By this adjustment, provision is made for variations in the direction of the tip line in different styles of shoes.

The yoke 50 has a pin and slot connection with the lever 60, Fig. 1, pivoted to the frame at 62 and actuated by engagement of a cam roll 64' located on the lever between its ends with a suitable cam on the main shaft 4. A pin 66 on the upper end of the lever 60 extends through a slot in the casing or frame 2 and engages a slot 67 in the yoke 50. Therefore as the upper end of the lever 60 is swung forward the yoke 50 will be swung about the pivot 49 into a vertical position with the marker 56 over the tip line of the forepart of the sole. During this movement of the yoke the lever 52 is also actuated by engagement of a cam roll 53 with a suitable cam on the shaft 4 to move the marker downwardly against the sole.

For starting the machine a starting handle 70 is provided which is connected with an arm 72 011 a rock-shaft 71 having an arm 75 secured thcreto at right angles to the arm 72 and connected by a bar 7 6 with the dog 78 of a one-revolution clutch which may be of any suitable form. As shown, the handle 70 is located under the sole when it is in position to be marked so that pressure on the sole causes the handle 70 to be depressed,

' the dog 78 to be lifted and the clutch members permitted to engage to effect rotation of the shaft 4.

It is desirable to relieve the operator of the work of removing the solo from the machine so that his entire attention may be devoted to feeding the work. For this purpose fingers 80 are provided which are let into the upper face of the table so as to lie beneath the sole flush with the table surface. The fingers 80 are fixed to a shaft 82 at the back of the machine. Rotation of the shaft 82 will raise the fingers which will carry the sole with them and cause it to slide back and rest on edge against the upright stops 84 or against the sole last stacked against the stops. The shaft 82 is rotated by movement of a slotted sleeve 86 longitudinally of the shaft 82, a pin 88 on the shaft 82 resting in the slot 89 of the sleeve 86. The sleeve 86 is carried by an arm 90 on a slide rod 92 which is operated from an angle lever 94 pivoted at 96 to the frame and having one arm secured by pin and slot connections to the rod and the other in operative relation to a cam 97 on the shaft 4 which is timed to slide the rod 92 and the sleeve 86 at the proper time in the cycle of the machine to remove the sole from the table to the stack.

It will be seen that the removal of the shoe automatically by the machine permits the starting handle 70 to be returned to its normal position and the clutch finger 78 to fall back into position to separate the clutch members and stop the machine at the completion of a revolution of the shaft 4.
