SOLE-LAYING MACHINE.
SPECIFICATION forming part of Letters Patent No. 557,744, dated April '7, 1896. Application filed January 14, 1898. Serial N'ox 575,491. (No model.)
To all whom, it may concern:
Be it known that I, Enasrus E. WINKLEY, residing in Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Sole-Layin g Machines, of which the followin g, taken in connection with the accompanyin g drawings, is a specification.
The present invention relates to improvements in machines of the above class; and it consists of certain improved mechanisms for relatively actuating the jacks and forms, operating automatically and successively to seat the forms and bring the jacks and forms into a position of pressure, of connections between said mechanisms whereby the operation of the jacl;seating mechanism automatically adjusts the pressure mechanism to the height of the shoe upon the sole of which the form is seated, of improvements in the construction and arrangement of the jacks and forms, and of the improved devices and combination of devices, as hereinafter more specifically set forth and claimed.
The object of the present invention is to increase the capacity and accuracy of operation of machines of the abovedesigna-ted class and to eliminate as far as practical therein the liability of injury to the shoe or its last.
The present invention is illustrated in the accompanying drawings, in which- Figure 1 is a front elevation of a machine embodying the same with portion of one of the cams removed to show underlying parts. Fig. 2 is a section on line a; 50, Fig. 1. Fig. 3 is a rear view, enlarged, of a portion of the carrier and portions of mechanism for seating the form and securing pressure between the form and jack. Fig. A is an enlarged plan view, partially in section, showing portions of mechanism for securing pressure between the jacks and forms. Fig. 5 is a side view of said mechanism, portions of the carrier beingshown in section on line y 3 Fig. Fig. 6 is a detached view of cam actuating the mechanisms for securing pressure. Fig. 7 is a top plan view of one of the jacks. Fig. 8 is a partial plan view showing one of the forms and a portion of the carrier. Fig. 9 is a partial rear view illustrating the stopping and starting mechanism.
a suitable base a, to which are secured the Figs. 10, 11, and 12 are detail views of one of the pressing-forms. Similar letters and figures of reference refer to similar parts throughout the several views.
In the drawings, A represents a frame suitable to support the working parts of the machine.
In practice I construct the frame A with 0 standards a and CF. The frame A may be, however, of any other suitable form.
In the frame A is mounted a suitable rotary carrier, conveniently in the form of a spider-frame B, which is arranged to receive a series of partial rotations, for the purposes hereinafter described, stopping automatically and being started at the will of the operator.
A preferred, though by no means essential, form of mechanism for securing the above re- 70 suit is shown in the drawings and described as follows: The spider-frame B is rigidly secured to and rotates with a shaft 1), which is mounted and free to turn in suitable bearings in the standards a and a of the frame I A. The shaft 1) is projected through its bearing in the standard a and back of the standard a carries a worm-gear b, which is engaged by a worm I) on the shaft [1 The shaft 11 is mounted in suitable hearings in the frame A, in which it is free to rotate, and is conveniently driven by means of the usual pulley b The pulley Z)" turns loosely about the shaft b and is connected therewith by a suitable clutch, mechanism being provided at the control of the operator for engaging the members of the clutch to cause the shaft Z2 and pulley Z2 to rotate together, and automatically-operating mechanisms being provided whereby the members of the clutch are 0 disengaged to stop the rotation of the shaft 6 and allow the pulley b to turn loosely thereon.
IVhile the form of the clutch above referred to or of its actuating mechanism in itself forms no part of the present invention, it may be desirable in this connection to briefly describe the specific form shown and its connection with other features of the machine.
The pulley in being, as before stated, free to rotate independently of the shaft 17 is also arranged to slide along said shaft, and the inner face of its hub is provided with a segmental slot, (not shown,) which is engaged by a pin 2 upon a disk 3, which rotates with and is held from motion along the shaft b (See Fig. 9.) Adjacent to the shaft b is a substantially parallel shaft b mounted in suitable hearings in the frame A or the brackets -l 4: thereon, in which it is free to rotate and slide longitudinally, being guided and held in position thereby. On the shaft b is a sleeve 5, free to turn thereon, but held from movement along the same by suitable collars. To the sleeve 5 is secured a fork or collar 6, which engages a groove on the hub of the pulley b. The shaft b also carries a bent lever '7, which turns therewith and is held from motion along the same. The lever 7 by means of a spring 8, secured to an arm 9 on the shaft b and to a fixed part of the machine, or by some other suitable device is normally held in such position that the upper end thereof projects in the path of a series of stops or dogs 10 10, &c., on the gear I), the abovedescribed arrangement being such that as the gear 1) is rotated one of the stops 10, coming in contact with the lever 7, moves it and the shaft 1) outward, and by means of the collar 6 moves the pulley b outward, causing the pin 2 to be withdrawn from the segmental slot in the hub of pulley b and allowing the pul' ley b to rotate independently of the shaft 19 At or near the lower end of the lever 7 is formed a socket 12, which receives the upper end of a rod ll, the lower end of which rests in a socket 15, formed upon the treadle b, fulcrumed at 16 on the frame A, or the lever 7 may be otherwise suitably connected with the treadle b, so that a depression of the treadle Z) causes the lever 7 to tip backward out of the path of the dog 10. \Vhen the lever '7 has cleared the dog 10, a suitably-placed spring 17 closes the clutch, causing the shaft 19 to rotate with the pulley b and the spring 8 again advances the lever 7, bringing its front end again into the path of the dogs 10.
The number and position of the dogs 10 will depend upon the number and position of the jacks on the spider-frame. In the form of my invention shown in the drawings, in which the spider-frame is provided with four jacks at substantially ninety degrees apart, I have used four dogs 10 (only two shown) at substantially ninety degrees apart upon the gear b.
Upon the carrier 13 are mounted a series of pressing-forms D D, &c,, and aseries of shoesupporting jacks E E, &c.
lVhile any suitable pressing-form can be used in combination with the mechanisms herein described without any departure from the present invention, 1 have in practice adopted a pressing-form which is an improvement upon the form shown and described in the United States Letters Patent No. 5&9A7l,
issued to me November 5, 1895, which, in order that one skilled in the art may readily construct a machine embodying my invention in the best form known to me, I will now describe in detail.
The form D, as shown in the drawings, comprises a rigid bed cl, Figs. 10, 11, and 12, having the general longitudinal contour of the bottom of a last, and to which is suitably secured a flexible pressing-pad d. The pressing-pad d is formed of a continuous block of rubber or other suitable elastic material and provided with a projected shank portion 61 and areinforcing-strip (Z covering, substantially, the edge-pressing portions of the pad, substanti ally as shown in my said Letters Patent. Between the shank portion (1 of the pad (1 and the bed (I is located the shank-block (1 which bears upon the pad d at the points (Z and (1 upon opposite sides of the shank and adjacent to the base of the reinforcing-strip (1 Upon the bed (Z is formed a boss (i in which is formed a chamber (P, which extends through the bed (1. To the block (1 is secured a stem (P, which is fitted to the bore of a tubular threaded bolt (Z which engages correspondingly-threaded bearings in the top of the boss (Z Upon the stem (Z is a collar (Z free to slide thereon, and between which and the block (1' is placed a coiled spring (1 The inner end of the bolt (Z bears upon the collar (Z the above-described arrangement being such that the block (1. is held in contact with the pad cl at the points (1 and d" by the action of the spring (Z which may be regulated by moving the collar (Z along the stem d by turning the bolt (Z in its threaded bearing. Vhen pressure is applied, the stem (Z moves along the bore of the bolt 10 to allow the block (1" to be forced toward the bed (Z, the stem (1 acting to guide the block (1 and keep it in its proper position. The chamber d is preferably enlarged at its base to form a recess (Z which receives the upper portion of the block (1*, so that the same will not, when forced against the bed d, form a ridge across the form, which would be apt to mar the sole.
The advantages which I claim for aform constructed as above described are its increased accuracy of operation, particularly at the edge portions of the shank, thus insuring an evenly-laid sole and the absence of any ridge or projection in the rigid parts thereof which would tend to mar or otherwise injure the solo.
The jacks E may also be of any suitable construction. I find, however, in practice that a form of jack substantially similar to that shown in the drawings secures the best results, partly on account of the ease and rapidity with which it can be adjusted, but principally because it makes a point upon the shank portion of the shoe a positive point for all sizes of shoes, thereby always bringing the shank portion of the shoe under the same part of the form, a result of great in1- portance in connection with a form having a projected shank portion, as shown in the drawings.
As shown in the drawings, each of the jacks E comprises a toe-rest e and a heel-support e, the bases of which are fitted to a dovetailed groove c in the base-plate 6 both the toerest 6 and heel-support (2 being movable along the plate a toward and away from each other. On the plate 6 is eccentrically pivoted a lever 6*, in the longer arm of which is formed a slot e (see Fig. 7,) which is engaged by a pin e upon the toe-rest e or a suitable projection e thereon. In the shorter arm of the lever is formed a slot 6 which is engaged by a pin a, secured to a projection e upon the heel-support e. The above-described arrangement is such that a movement of the toe-rest 6 along the plate 6 causes a movement of the heel-support c in an opposite direction and to a less extent, and vice versa. The relative length of the arms of the lever c" determines the relative movement of the toe-rest and heelsupport, and since there is a proportional variation in the lengths of the several parts of a sole in the different sizes of shoes it is evident that the lever 6: can readily be arranged so that the shank of a large shoe will be brought to substantially the same position under the form as the shank of a small shoe.
I am aware that in certain forms of solemachines it has heretofore been proposed to so arrange the jack that the toe of the last is made a positive point for all sizes, while in others the positive point is at the heel or at the center; but so far as I am aware of the art no jack has been heretofore provided in which a point on the shank is made the positive point for all adjustments for length.
The toe-rest c and heel-support e as above arranged may be lconveniently locked in any desired position by means of a spring-pressed pawl c, mounted upon the toe-rest e and arranged to engage a series of notches e upon the plate 6 In all machines embodying a rotary carrier and series of jacks and forms thereon there are three essential movementsfirst, a rotation of the carrier; second, a relative movement of the jacks and forms from a position of clearance to a position of pressure, and, third, a movement of the jacks out of operative relation to the forms, whereby they are presented to the operator in convenient position for the removal or adjustment of work. I may say in this connection that the jacks and forms are said to be in a position of pressure when their relative position is such that the sole of a shoe upon a last placed upon the jack would be sufficiently compressed against the form to properly perform the sole-laying operation and that the jacks and forms are said to be in a position of clearance when their relative position is such that the jack can be moved with a shoe thereon away from the form into a convenient position for the removal of a shoe therefrom.
Having hereinbefore described a preferred form of mechanism for rotating the carrier, I will now describe a preferred form of mechanism whereby the jacks and forms are moved relatively to each other to produce compression and clearance.
In accordance with the present invention the relative movement of the jacks and forms from a position of clearance to a position of pressure occurs in two steps, the first step seating the form firmly on the sole of the shoe upon the jack and the second step bringing the form and jack into a position of pressurethat is, forcing them together with sufficient pressure to successfully perform the sole-laying operation.
The advantage which I gain by dividing the relative movement of jacks and forms as above explained is that I am thereby enabled to use a powerful positively-actuated mechanism for producing pressure, which is automatically adjusted by the seating of the form to the height of the last, and thus, while securing great pressure, to avoid any danger of injury to the last or shoe.
As shown in the drawings, each of the forms D is supported by a swinging lever F, which I have hereinafter called the formlever, and which is fulcrumed at f on one of the arms 19 of the spider-frame B.
The lever F in practice consists of the substantially parallel arms f f, (see Fig. 8,) united at one end and at the opposite end embracing a sleeve f upon the spider-arm If. A trunnion extending through both of the arms f f and the sleeve f secures the lever F to the spider-arm and leaves it free to operate, as hereinafter described. The form D is preferably secured to the lever F by a trunnion f which is mounted in the arms f f and extends through a bearing (Z in the boss (1 (see Fig. 10,) leaving the form D free to tip longitudinally. In practice the bearing (Z is located substantially over the center of the bed (Z, and I have provided near each end of the bed d a coiled spring f (see Fig. 10,) which bears against the bed cl and a movable plate f. In the lever F are provided thread-bearings f which receive the bolts f, the lower ends of which are fitted to sockets in the plates f Each of the plates f has upon its under side a circular boss 20, which engages one or more coils of the spring f and prevents the same from slipping from the plate. A similar boss and for a similar purpose is formed upon the bed (Z.
The abovedescribed arrangement is such that by turning the bolts f f the action of the springs f f" maybe regulated as required, so that the longitudinal tipping movement of form D is controlled by elastic adjustable stops, which is a feature of considerable advantage in this class of machines.
As shown in the drawings, the seating of each of the forms D is accomplished by means of a spring H, which is secured to the lever F and to the spider-frame B, conveniently at the points h and h.
To the standard a of the frame A is bolted or otherwise suitably secured a cam O, the form of which will be hereinafter more fully described, and upon the lever F is secured a cam-roll c or othersuitable projection, which, as the spider-frame B rotates, engages the cam O and raises the form D into a position of clearance. As the spider-frame B is further rotated, the cam-roll cleaving the cam C, the spring II, acting upon the lever F, brings the form D down upon the sole of a shoe upon the jack E.
YVhile it is preferable that the form should be firmly seated upon the sole by the spring II, as above explained, it is not intended thereby to secure sufficient pressure to perform the sole-laying operation, although by increasing the strength of the spring H or by substituting therefor a series of springs such operation can be successfully accomplished upon many grades of work and further mechanism for securing pressure dispensed with.
I will now describe in detail the form of mechanism shown in the drawings by which, after the form is seated, I secure the necessary amount of pressure to properly lay the sole.
Reference being had more particularly to Figs. 3, 4, 5, and 6 of the drawings, R represents a link pivotally connected with the lever F, preferably adjacent to its free end, and also pivotally connected with a reciprocating rod 7' or a suitable offset 7*, fixedly secured thereon. In practice I have provided a casing 7- which is bolted or otherwise fixedly secured to the spider-frame B and in which are provided bearings 9' and 7*, (see Fig. 5,) in which the rod 1' is free to reciprocate longitudinally, being guided and held in position thereby. On the rod 1' is a collar "1"", free to slide along the rod 0 and from which is projected an arm 7", which is acted upon by a lever 1' conveniently pivoted at 1' upon the spider-frame B and carrying a cam-roll T, which works upon a cam R, bolted or otherwise suitably secured to the standard a of the frame A. The collar 7' is supported by a suitably-placed spring 1- which may conveniently consist of a coiled spring surrounding the rod 0 and bearing against the collar 7' and the ofiset r projected from the spiderframe I3. The rod '1' extends through the 0&- set 7', and a bearing for the rod r is provided therein.
The above-described arrangement is such that the rod 7' is free to slide through the collar 7' until the lever r is depressed by the action of the cam R upon the cam-roll 7' but when the lever 1- is depressed, as above stated, acting upon the arm 7", it cramps the collar 7 on the rod 7' and forces down said rod, for the purposes hereinafter stated.
hen the shape of the cam R permits the cam-roll r to approach the center and thus relieve the pressure on lever 0, the collar 1' is no longer cramped, but the rod 7 is again free to slide through the same, and the collar 0* is returned to its original position by the action of the spring 0" Of course it is understood that the collar 7 has a comparatively short bearing on the rod 1", and when power is applied away from the rod toward the end of the arm 6 the collar r becomes cramped or binds on the rod 1, forming a positive and easily-controlled clutch which is capable of sustaining great strain without danger of breaking o1 slipping. To allow for the relative movement of the lever 1' and the arm 1*, I have in practice made the following provision: On the arm "1' is a collar Z, free to turn thereon, but held from movement along the same. The collarZ is provided upon opposite sides with suitable sockets, which are engaged by the inner ends of the thread-bolts Z Z having bearings in a link Z, which surrounds the collar Z. From the link Z is projected a cylindrical stem Z which is fitted to a sleeve Z on the lever 1. The stem Z is free to rotate in the sleeve Z and is held in position therein by a suitable collar 1*. I would say that in practice, the motion of the lever 7' being on both sides of the center, the abovedescribed arrangement with the common machine fits will allow sufficient play of parts and is simple and durable.
It is evident that when arranged as shown in the drawings, if the jacks E are empty, the rod 4', before pressure is applied, will be moved downward through the collar 7' by the action of the spring H, acting through the lever F and link R, until the lever F rests upon the casing 0' or some other fixed portion of the machine; and it is further evident that if, when the parts are in the position above stated, the cam R is allowed to act upon the lever r to further depress the rod 7' some part of the machine will be broken or strained.
To avoid the above-stated difficulty, I have provided what I have called a safety device, and which, as shown in the drawings, consists of a stop R dependent from the rod 0, conveniently from the offset r, and which before the lever F comes in contact with any fixed portion of the machine strikes the col ITO lar r and depresses the same until the arm I will now describe the mechanism shown in the drawings whereby the jacks are moved out of operative relation to the forms.
From the bed-plate e of each of the jacks E are projected the lugs 92 n, in which is fixedly secured a shaft n, having bearings in the projections 11 n on the spider-frame 13. From the base-plate e of each jack E is projected a fixed arm 92 the outer end of which (preferably provided with a cam-roll) bears upon a cam N, bolted or otherwise fixedly secured to the standard a of the frame A. A suitablyplaced spring, preferably consisting of a coiled spring a coiled about the shaft n and secured thereto and to the spiderframe 13, acts to throw the jacks outward and to keep the arm n in contact with the cam N. In practice I make the cam N circular, except at the top, where a depression 71 is formed. The above-described arrangement is such that as the spider-frame 13 rotates, the arm n of each jack E, bearing against the cam N, holds the jack in a substantially vertical position under its form D until the arm of falls into the depression of the cam X, when the spring n forces the jack out of operative relation to its form, presenting it to the operator in convenient position for the removal or adjustment of the work. A further rotation of the spider restores the jack to its vertical position under the form.
In practice I have provided a shelf P at the top of standard a of frame A, which projects over the spider-frame B and affords a conyenient and easily-accessible place for the operator to keep his soles while using the machine.
While the specific form of the several cams hereinbefore referred to is by no means an essential feature of the present invention, I will give a brief description of the forms thereof as shown in the drawings, and which I have found in practice to operate successfully.
The cam B may conveniently be formed, substantially as shown in Fig. (3, with an outer circular portion 30 and an inner circular portion 31, connected by the inclined portions 32 and The cam Ris in practice secured upon the standard (4 with the inner circular portion at the top and symmetrically arranged with reference to the vertical diameter of the spider-frame 13.
The cam X may conveniently consist of a circular disk with the depression 91 which when the cam N is in place upon the standard a is at the top of the cam and symmet rically disposed with reference to the vertical diameter of the spider-frame.
The cam C may conveniently be formed with a circular central portion a and inclined end portions t1 and 42. When secured to the standard (4 the cam G is also symmetrically disposed with reference to the vertical diameter of the spider-frame.
The relative extent of the several portions of the cams above described will be readily circular portion 40 of cam C, and the jack E associated with said form being out of operative relation thereto, with its arm n resting in the depression 91 of the cam N, and the cam-roll 7' being upon the inner circular portion of the cam R, so that the rod 1' is free to slide through the collar 0- power being applied to the pulley b the operator, having re moved the finished work and jacked the shoe to be operated upon, places the cemented sole in position and by depressing the treadle b sets the spider-frame B in rotation. As the spiderframe B rotates, the arm 71 being carried out of the depression 11 onto the circular portion of the cam IT, raises the jackE against the action of the spring n and brings it into operative relation to the form D. As soon as this is done the cam-roll 0, being carried down the inclined portion $2 of the cam 0, allows the spring H to depress the lever F until the form I) is seated upon the sole under the pressure of spring H. \Vhile the spring H has been seating the form D on the sole it has also, by means of the link R, been depressing the rod 1' through its collar 0*. hen the form D has been seated as above stated, the rotation of the spider-frame B brings the cam-roll 7* onto the inclined portion 33 of the cam R, and the lever 7' being depressed cramps the collar r on the rod 1 and depresses said rod and the form D until the cam-roll o has reached the outer circular portion of the cam B, when the form is in its position of maximum pressure. It is to be noted in this connection that the mechanism for giving the final motion of pressure to the form D is automatically adjusted for the height of each last and thickness of sole thereon by the seating of the form, so that all lasts, whether high or low, are subjected to an equal amount of pressure, a result of greatest importance in machines of this class. The form D continues in the position of maximum pressure until the rotation of the spider-frame B brings the cam-roll 0' around to the inclined portion 32 of the cam R, when the lever r is released, releasing the rod 1', and the camroll c, engaging the inclined portion 41 of the cam C, passes up onto the circular portion of said cam, raising the lever F and bringing the form D into a position of clearance, when the arm or drops into the depression 12 in the cam N, allowing the spring a to throw the jack E out of operative relation to the form D, and the rotation of the spiderstops. Vhen four jacks are used, as in the machine of the drawings, the rotation of the spider-frame B is stopped at every quarter-turn, leaving one form in position of clearance and its jack out of operative relation thereto, while all the other jacks are under pressure. \Vhen a different number of jacks is used, a stop is made for each jack, as above explained.
As the operation of the mechanisms associated with each form and jack are substantially the same, the above description is regarded as sufficient.
It is of course understood that the operator removes the work from and adjusts new work upon the jacks successively as they are thrown out of operative relation to their forms.
Should any of the jacks be left empty and the spider-frame B set in rotation, when the cam-roll 0 reaches the inclined portion a2 of the cam C the spring II acts to depress the lever F, as before described; but before the lever F comes in contact with the casing 7 or any fixed portion of the machine, the stop R strikes against the collar and depresses the same until the cam-roll r clears the cam R, so thatwhile the spider B is making its rotation the cam B does not act to further depress the rod 2'.
To adjust any of the jacks E for any length of last, the operator disengages the pawl e and moves the toe-rest 6 until the toe-rest e and heel-support e" are in position to properly support the toe and heel of the last, which, without further interference on the operators part, brings the shank in position to properly receive the projected shank portion of the form D.
Having thus described my invention and its mode of operation, I desire to say that, while shown in the drawings as associated with a sole-laying machine involving a rotary carrier, certain features of the present invention are broadly novel and are not limited in their application to the specific machine shown, since with slight modifications involving no departure therefrom they could be readily adapted to other forms of sole-laying or soleleveling machines not involving a rotary carrier.
