" MACHINE FOR LEVELING SHOE-SOLES.

SPECIFICATION forming part of Letters Patent No. 656,764, dated August 28, 1900.

Application filed July 12, 189,9. Serial No. 723,587. No model.)

To all whom it may concern:

Be'it known that we, HARRY E. OILLEY and CHARLES S. GOODING, citizens of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Machines for Leveling Shoe-Soles, of which the following is a specification.

This invention relates to the type of machines for leveling shoe-soles described and shown in Letters Patent Nos. 563,666 and- 591,766, issued, respectively, July 7, 1896, and October 12, 1897, to Judd and Oilley.

The chief objects of the present invention are to generally improve and simplify the prior machines and facilitate their operation, whereby it is possible for any operator or workman to properly manage the same, adapt them for shoes of varying size andsoles of diiferent contour, and obtain the best results.

The invention also has for its object to provide novel, simple, and effective means for automatically raising a leveling-roll from the shoe-sole during the leveling operation.

Theinvention also has for its object to provide novel means for varying; the time at which the leveling-roll is automatically raised from the shoe sole, whereby the point on the sole at which it is desired to raise the roll from 0 the sole can be changed to suit the conditions required.

The invention also has for its object to provide novel means for varying the extent to which the roll is automatically raised from the sole.

The invention also has for its object to provide new and improved means for mounting the shank-roll and enabling it to operate correctly according to the conditions required 0 in acting upon sole-shanks that vary in contour. 7

The invention also has for its object to provide new and improved means for locking the horizontally or laterally movable shoe-supporting arm to and unlocking it from the rocking jack-frame.

The invention also has for its object to provide novel and simplified means for'vibrating the fore-part and shank rolls during the lev:

' 5o cling operation.

'To accomplish all these objects, our invention involves the features of construction, the combination or arrangement of parts, and the principles of operation hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure 1 is a side elevation of a sole-leveling machine embodying our invention. Fig.

Fig. 8 is a detail broken plan view showing the devices by which the shank-roll is mounted on the vibratory carrier-frame. Fig. 9 is a front elevation of the same. Fig. 10 is a vertical sectional view taken on the line 10 10, Fig. 9; and Fig. 11 is a diagrammatical view of a shoe-sole having a crooked or irregular shank.

In order to enable those skilled in the art to make and use my invention, we will now describe the same in detail, referring to the drawings, wherein the numeral 1 indicates a suitable main frame having bearings at its base portion,in which a driving-shaft 2 is journaled. This shaft is geared to and drives a gear-wheel 3, secured to a shaft 4:, having an eccentric 5, connected by a rod 6 and cocentric-strap 7 with an arm 10, forming a part of the longitudinally-rocking jack-frame 9o 12. The arm 10 is preferably curved, and the connecting-rod 6 is pivoted to the arm by a pivot, as at 13. The gear-wheel 3 is driven at comparatively-slow speed and by the connections set forth slowly rocks the jack- 5 frame, which latter carriesthe laterally-movable shoesupporting arm or frame 14, one or more, pivoted at 15, and carrying heel and toe posts 16 and 17, preferably constructed and adjustable as in either of the former 10c patents, but which can be of any other suitable type. The ordinary or any suitable treadle 18 is connected by the usual vertical spring- rods 19 and 20 with the pivoted yokeshaped frames 21 and 22 that support the fore-part and shank rolls 23 and 24. As in the prior machines referred to and others of this class or type, the springs forming parts of the spring- rods 19 and 20 serve to permit the rolls 23 and 24 to yield upward during the leveling operation, and when the springrods 19 and 20 are released by unlocking the treadle the said springs and the counterbalance-weight 59 cause the rolls to rise. The chank-roll mounted on carrying devices in the yoke-shaped frame 22 is vibrated by a bell-crank lever having a vertical arm 25 and a horizontal arm 26. This lever is pivoted at its angle to a shaft 27, mounted in a bearing on the main frame, and its horizontal arm is pivoted to the upper end of a connectingrod 28, engaged at its lower end with an eccentric 29 on the driving-shaft 2,whereby the lever is more or less swiftly vibrated. The vertical arm of the bell-crank lever is provided with two bearings 30 and 31, Figs. 2 and 3, at different heights or levels. The lower bearing 30 is designed to be pivotally connected with and vibrate the carrying devices of the shank-roll 24 on the yoke-shaped frame 22, while the upper bearing connects by a rod 32 with the carrier or frame 33,which directly carries the fore-part roll 23, the construction being such that as the bell-crank lever is rocked or vibrated the shank-roll is vibrated in the pivotallymounted yokeshaped frame 22 and the fore-part roll is 0scillated or vibrated in the pivotally-mounted yoke-shaped frame 21. These yoke-shaped frames may be pivotally mounted in any suitable mannerfor instance, as in the former patents.

The yokeshaped frame 22, supporting the carrying devices of the shank-roll, is automatically and positively raised at recurring intervals to raise the shank-roll from contact with the shoe-sole during the leveling action of said shank-roll, as we will now explain, such automatic raising of the shank-roll from contact with the shoe-sole being entirely independent of the action of the springs in or forming parts of the spring-rods l9 and 20. The purpose of this operation of raising the shank-roll from the sole of the shoe during the leveling operation is to insure that the heel-seat of the shoe will not be leveled. It is not desirable that the heel-seat of the shoe should be leveled, and it will be readily seen that if the fore-part roll is carried onto the shank of a small-size shoe there will not be sufficient room in the shank for both the shank-roll and the fore-part roll. Therefore according to our invention mechanism is provided for raising the shank-roll from the shoesole, so that it will not pass over and level the heel-seat or fall off the end of the shoe. A bell-crank lever 34 is pivoted at its angle portion on the shaft 35, mounted in the top The lever comprises two of the main frame.

arms 36 and 37, the latter bearing against the cam-shaped edge of a cam 38 and the former carrying a vertically-adjustable set-screw 39, hearing against a bracket 40 on the frame 22. The cam is substantially a segmental ring, Fig. 10, mounted on the periphery of a wormgear 41, keyed to a rock-shaft 42, journaled in the main frame, and the ends of the ring are provided with bearings 43, in which is journaled a rotary worm 44, the shaft of which has a finger-piece or handle and lock-nut 46. The worm-gear is provided at its inner side with an annular flange 47, Fig. 9, and at its outer side with an attachable and detachable ring 48, the cam-ring being confined between the flange 47 and ring 48. The rock-shaft 42 has a crank-arm 49, pivotally connected by a link 50 with the arm 10 of the jack-frame, and consequently as the latter rocks an oscillating motion is imparted to the cam 38, and its cam edge acting on an antifriction-roller 51 at the end of the arm 37 of the bell-crank lever 34 causes the arm 36 thereof to rise, whereby the yoke shaped frame 22 and shank-roll 24 are caused to correspondingly rise. The extent to which the frame 22 is lifted and shank-roll 24 is raised independently of the action of the springs in or forming parts of the spring-rods l9 and 20 is regulated by the adjustable set-screw 39, as will be obvious. The time when the lever 34 is operated and the frame 22 and shankroll are raised can be varied to suit the conditions required through the medium of the worm 44, engaging the worm-gear 41. By turning the Worm in the proper direction by its finger-piece or handle the cam will be turned the required distance around the worm-gear to obtain the necessary adjustment of its cam edge relatively to the roller 51 on the end of the arm 37 of the bell-crank lever 34, after which the worm is locked by the locknut 46. Itis evident, therefore, that the time at which the lever 34 is actuated to lift the shank-roll can be varied at will or changed with relation to the motion of the jack-frame and the point on the shoe-sole at which it is desired the shank-roll'should rise therefrom. The rocking jack-frame is secured to a rocking jack-shaft 52, carrying a cam 53, having in its inner face a cam-shaped race 54, (best seen in Fig. 4,) constructed at its ends with rest portions 55 and 56. The cam has an arm 57, pivotally connectedby a link 58 with the usual lever 59, carrying the counterweight 59", and pivotally connected at its front end with the treadle 18 by a link 60. The race 54 of the cam 53 is engaged by a roller-stud 61 on the arm 62 of a bell-crank lever 63, pivoted at its angle, as at 64, and having its other arm 65 slotted at its rear extremity to receive a pin 66, secured to a locking-bolt 67, Fig. 8, movable vertically in a socket formed in a part of the jack-frame, so that the bolt will lie directly under and engage a locking notch or recess 68 in the under side of the rear end of the shoe-supporting arm 14 when it is in normal position for a'shoe-sole to be leveled. When the treadle 18 is depressed and held down, the cam 53 will be turned so that the central part of the rest portion 56 of the cam-race will be presented to the rollerstud 61 of the bell-crank lever 63, and there-- fore the jack can rock without the lever 63 being oscillated, in consequence of which the bolt 67 remains in engagement with and locks the shoe-supporting arm to the jack-frame; but when the treadle is released and thrown upward by the weighted lever 59 the cam 53 will be turned so that the acting part of the cam-race will depress the lever 63 and cause it to retract the bolt fromlocking engagement with the shoe-supporting arm, whereupon the latter can be moved or swung laterally. After the treadle is raised the rollerstud 61 will be presented to the rest portion 55 of the cam-race, the jack may rock without moving the lever 63 in the manner required to actuate the bolt 67, and the bolt will be held retracted. The upper end of the locking-bolt is double beveled, and it is pressed upward by a spring 69 to snap into engagement with the shoe-supporting arm when it is moved or swung to normal position or in alinement with the jack-frame. The spring may serve to throw the bolt upward; but obviously the cam 53, acting on the lever 63, may serve that purpose,

Referring now to Figs. 8, 9, and 10 of the' drawings, the two-part shank-roll 24 is rotatably mounted in studs carried by segmentally-slotted holders or plates 85, arranged on a plate 91, supported, through the medium of a pivot 92, by a carrier 86, pivotally mounted on the upper and lower ends of a vertical pintle or pivot-pin 88, arranged in a bearing 89 of the carrier-frame 87. The carrier 86 is formed with a front depending arm or hanger 82, which extends rearwardly and forms the upper bearing for receiving the pintle or pin 89. A set-screw S is provided for impinging against the pintle or pin to prevent it from falling through the bearing 89. By this construction the carrier 87, the plates 85, and the twopart shank-roll 24 are susceptible of swinging in a horizontal plane, so that the axis of the roll may assume the positions in dicatedby the dotted lines 90 on a shoe-sole, the shank of which is of greater length at its inner sides than at its outer sides, as clearly shown in Fig. 11 of the drawings.

Our improved arrangement, in which the shank-leveling roll is mounted to swing in a plane parallel with the shank-face of the last, or, in other words, horizontally, as shown in the drawings,is of much advantage,as thereby the shank may be leveled over its entire surface quickly and satisfactorily without manipulation either of the shoe or the leveling mechanism. As well, known the shank portion of a shoe is longer at its inner edge than its outer edge. By reason of our novel arrangement the movement of the outer end of the shank-leveling rollwill be arrestedor stayed at the forward limit of the outer side of the shank of the shoe, and said roll will swing in a plane parallel with the shank of the shoe and its inner end continue its travel to the forward limit of the inner edge of the shank. Thus the entire surface of the shank may be leveled without manipulation either of the shoe or the leveling mechanism and without crushing any portion of the shank.

The plate 91 at the front on the carrier 86 is mounted on a pivot-screw 92, passingthrough the lower end of the hanger 82, and. the segmentally-slotted plates 85, in which the twopart roll is journaled, are connected to the plate 91, so that the shank-roll by reason of its connection with the plate 91 is capable of swinging in a vertical plane to accommodate varying conditions of work and varying contours of shoeshanks. The segmentally-slotted plates are adjustable on the plate 91 and are held in adjusted position by means of thumb-screws 93,en gaging screw studs 94,proj ecting from the plate 91, so that the segmentally-slotted holders or plates may be independently adjusted in the arcs of a circle on the plate 91 to vary the angle of inclination of the axis of each part of the two-part shankroll, thereby adapting the roll to properly operate upon shoe-shanks which vary in contour or to suit other conditions that may arise.

The horizontal and vertical swinging movements of the shank-roll 24 described are au tomatic, as will appear.

The mechanism for automatically raising the shank-roll at predetermined or recurring intervals may be applied to either of the machines disclosed by the Letters Patent hereinbefore referred to. In the former machines the shank-roll was given a reciprocating motion (in addition to its vibratory motion) of, say, six inches, while the shoe moved a distance of, say, nine inches. The difference of three inches is the distance the shank-roll traveled upon the shoe-sole. It is inconvenient to limit the travel of the shank-roll upon the sole-shank, and the shank-roll is'therefore liable to travel onto the breast of the heel and round off the edges thereof. This is effectually avoided by the present machine, as the reciprocating movement of the shank roll is eliminated, the shank-roll is lifted at to place the machine under control of the operator. and enable any workman to readily manage the machine and adapt it to shoes of different sizes.
