NATHAN J. SIMONDS, OF WOBURN, MASSACHUSETTS.

HEEL-STIFFEN ER MACHINE.

SPECIFICATION forming part of Letters Patent No. 530,462, dated December 4, 1894.

Application filed June 23, 18 92.

Be it known that I, NATHAN J SIMoNDs, a citizen of the United States, residing at Weburn,in the county of Middlesex and State of Massachusetts,have invented certain new and useful Improvements in Machines for Forming Counter Stilfeners for Boots or Shoes, of which thefollowing is a specifica' tion, reference being had therein to the accompanying drawings.

My invention has for its object to provide a durable and efficient machine for forming shall be economical and speedy in its operation and it consistsin a machine employing wheelor rotary form carrier upon which the forms or male molds, over and upon which the counters are molded or formed, are carried,

female molds and means for operating the the form, and devices for rubbingor pressing down the flanged portions of the counter, all said mechanism co-operating to produce a full molded counter from a blank of leather or leather board or similar material all as will be hereinafter more fully set forth.

The novel features of my device are pointed out in the claims which are appended hereto and made a part hereof.

In the accompanying drawings in which I have shown my invention embodied in the best form now known to me and to which reference will be made in the following descrip- Fig. 2 is a side elevation and Fig. 3 is a plan view. Figs. 4, 5 and 6 are respectively a plan, side and end view of th lever arm which carries the movable female dies. Figs. 7, 8 and 9 are details of the toggle arm which carries the heel finishing die. Figs. 10 and 11 are respectively a plan and side view of the disk from whichthe lever arm,shown in Figs. 4, 5 and 6,is operated. a t

The machine and its operation will be readily understood from the following description.

Like letters of reference refer to like parts throughout the drawings.

The main shaft is shown at A andis mounted in a suitable upright frame B, which consists Serial No. 437,760. (No model.)

gether by suitable cross pieces. The precise shape of the frame is unimportant.

The form of the frame employed by me will be clearly seen from the drawingsand particularly from the side elevation shown in Fi 2. Onthe main shaft A is mounted a belt pulley O. A friction wheel or disk D, which is adapted to co-operate with the pulley O, is operated by means of a shipper lever E and suitable intermediate mechanism, all of Well known construction, so that the operator by moving the shipper lever may stop and start the machine. At the other end of the main shaft is a balance wheel F, and said shaft also carries a pinion a which is in mesh with a gear b which is fast on the short shaft 0 which is journaled in the uprightsB. Said shaftc is provided with a pinion a which meshes said shaft is mounted on the rotary form carrier d or large wheel which carries the forms e upon which the counters, as the counter stiffeners are usually termed, are formed or molded. Therotary form carrier may be provided with more than two forms, but Iprefer to use two, as shown.

The sole of the human heel curves from the shank to the rear portion of the heel and it is desirable that the periphery of the form carrier should coincide substantially with this curve, in order that the flanges of the counter may be rubbed and set on this curve thus permitting the bottom of the counter to fit the last and the foot more accurately than it otherwise would. This consideration will determine toa considerable extent the diameter of the form carrier d. The two forms 6 which I employ are set opposite each other on said form-carrieras indicated by dotted lines Fig.

and a counter blank a which is fed into position by mechanism which will hereinafter be described, comes in contact with the form and is carried upwardly between the rolls a which bend its ends around the form and it is then carried between the dies or female molds f. The concavity of each of said dies f is adapted to fit one side or one half of the form 8 and said dies f are mounted as hereinafter described so that they may approach or recede' from the form 6. The lever arms h which carry the dies f are each mounted as shown more clearly in the details Figs. Land 5, said arms being pivoted or journaled on the shaft 0 of the form-carrier, so that they may be reciprocated in a plane parallel with the plane of revolution of the form carrier.

The arm it must move with the form-car rier cl while the female diesf are in contact with the counter blank on the form e in order that the blank may be pressed and molded by the said dies. After the dies have done their work they are withdrawn from contact with the counter, and the arm h then moves in the opposite direction back to its normal position to be in readiness for the succeeding form and counter blank. For the purpose of moving arms h the yoke-shaped levers b are provided which are pivoted on the journals or bosses of the arms h as shown in Figs. 4 and 5 so that they may be rocked toward and from the arms h. At the upper end of each of the. levers b is pivoted a sliding arm or projection c which as the lever 19 is rocked slides inwardly and outwardly in a transverse slot in the lever h. When the lever Z9 is in its normal position shown in Fig. 4 the inner end of the sliding projection c is in the path ofthe projection g, see Fig. 2, which is on the side of the rotary form-carrier d. As the form-carrier rotates the projection 9 will come in contact with the inner end of the sliding projection c and the lever arm It will be caused to move with the form-carrier. When the lever arm it has reached the end of its movement the block (1 at the opposite end of the lever b comes in contact with a camshaped projection 6 on the inside of the frame which forces the lower end of the lever b inwardly thus withdrawing the projection or arm 0 from contact with the stop g and at the same time withdrawing the die f, the arm 12 coming in contact with the stop al for this purpose. The arm his then free to be moved back again to its normal position. The arm b is moved in the opposite direction by means of the spring 10 For the purpose of moving the arm h in the reverse direction, that is, back to its normal position I providea connecting piece e which is pivoted at one end as shown in Fig. 2 to the rear of the arm h and which projects rearwardly to the diskf shown in Figs. 10 and 11. The rear end of the arm a is provided with a projecting plate g see Fig. 2 which rests on the periphery of the disk f and the rear end of said arm is notched or provided with, a shoulder as shown at h Fig. 2. A pin or studj which is set on the face of the disk f engages the shoulder h when the arm 'e is in its rearward position and as the disk f revolves forces the arm a forward until the said pinj clears said shoulder. h isreturned to its normal position. While By this means the arm the pin 7' is out of contact with the shoulder h the arm is free to be moved rearwardly as will be clear. A diskf" and arm (2 are provided for each of said arms h. For the purpose of molding the blank on the form e the diesf must be forced inwardly against the blank on the form. To permit of this,,dies f are mounted on holders land a T-shaped projection shown at 10 Fig. 5 which slides in a corresponding T-shaped groove or slot in the upper end of the arm h. The die holders may therefore slide towardor from the rotary form carrier.

In order to permitthe dies f to be readily taken out of the machine when for any reason that is desirable they are provided with similar T-shaped projections which are received in vertical slots in the die holders Z as shown in Fig. 6. The die holders Z are provided with rolls it which as the arms h move engage the cam blocks j, see Fig. 1, which are secured to the frame of the machine and which operate to force the die holders and dies inwardly against the counter blanks on the form. As the form 6 and diesf continue their move ment the rolls k traverse the substantially fiat side of the cam blocksj thus continuing the pressure of the dies f on the counter blank for a sufficient time to thoroughly mold and set the fibers of the material in shape.

When a counter blank is clamped securely between the form 6 and the dies f, the edge thereof which is to form the flange in the finished counter projects upwardly above said dies and form. For the purpose of turning this flange over and ironing and rubbing it down so as to set it thoroughly in place, I have provided the jaws p which are pivoted to the under side of the cross piece g which extends between the uprights B. The jaws p are so set that as the diesf and form 6 pass under them they will come in contact with the projecting edge of the counter blank and press it down over the sole or bottom of the form 6. As the flange of the counter is to project inwardly toward the center of the form e I deem it desirable that the jaws 19 should move inwardly toward the center of said form as the form passes uhder them. To this end I provide rolls? on the die holdersl which as the dies reach a given point in their movement come in contact with the beveled ends 8 of said jaws p thus forcing the jaws inwardly and causing the flange to be wiped and rubbed down in an even and regular manner. The further onward movement of the form 6 forces the counter under the flange rubbing piece t which extends rearwardly and which is curved to correspond with the path of movement of the form on the rotary formcarrier of and thus the counter flange is thoroughly rubbed and set in position on the bottom of the form 6 forming an even and smooth heel seat. The flange rubber t is preferably mounted as shown in Fig. 2, it being bolted to a cross piece extending between the upright or side frames B, and being provided with a backing 29 composed of one or more strips of rubber or similar yielding material to allow the flange rubbing device to accommodate itself slightly to material of different thick nesses. The jaws p are returned to their open position bymeans of a spring 1/. or in any other well-known manner.

While I deem it desirable to employ the pivoted jaws p, a solid piece of metal having a U shaped notch corresponding somewhat to the opening between the jaws 19 as shown in Fig. 1 may be employed. Such a shaped piece of metal is old and well known for this purpose and is employed in many forms of counter molding machines now in use. The dies f are in fact two halves of a split die, and after the counter has, been subjected to their operation it may have a slight Iridge. or projection up and down the backof the heel caused by the material bulging into the opening or joint between the two diesf. When a split die is used this ridge or projection will be more or less apparent, and in some classes of counters it is objectionable. To obliterate this ridge or projection and produce a counter with a smooth back I subject the counter Whileit is on the form e and afterit has left the diesf to the action of another die which acts upon the counter around the back of the heel only. I have also found it desirable in mak-- ing a counter to subject the back of the heel or heel portions thereof to a strong molding pressure after the sides have been molded, not only for the purpose of obliterating the ridge which I have referred to, and making a smooth back, but also because such a pressin dotted lines Fig. 2.

ure sets the counter to shape and produces a better counter and one that will keep its shape better. tra molding operation at the back of the heel when it is desired to do so, I have provided a heeldie shown at Z Fig. 2, which is adapted to fit the heel portions of the form e and which is broughtinto contact therewith, or the counter thereon, after the side dies f have been released and after the counter has been carried under the flange rubbing piece.

die to yield slightly under pressure as also to accommodate itself to the form. The die holder a is formed on one end of the toggle arm 0 and the upper end of the toggle arm is set on a rock shaft (1 see Figs. .1 and 2, which is journaled in the upper part of the frame B. about midway of the vertical lever g shown The lever g is secu red to a rock shaft 72.. journaled in the top of the frame and at thelower end carries a cross In order to give the counter this ex-.

The lower toggle arm f is pivoted Fi 2 which en ages cams 10 of the sha e .7 s a s P shown by dotted lines Fig. 2. The cams k are cut in the proximate faces of the Wheels m which are mounted on theshaft Z As the cam wheels revolve the lower end of the 1ever"g is' moved toward and. from the formcarrier d. As said lever g moves from the position in which it is shown Fig. 2 toward the form carrier, that is toward the left in said figure the heelmold Z will be moved forward and directly into the path of the form 6 so that after the form passes the flange rubbing piece t, the backof thecounter thereon will be pressed into the said heel mold Z and the mold will exert a strong pressure upon the back of the counter. on the form, obliterating any ridge which may be left by the dies fand further forming and setting the counten to shape. The movements of the mechanismwhich operatesthe heel die Z are so timed that as soon as the said die has exerted a strong pressure on the counter on the forms the cams kit will be in a position to allow the trucksj on the lever g tobe moved back.-

Wardly along the cam path so. that the onward movement of the form 6 will operate to push the. heel die Z back out of the path of the said form. n Fig. 2, is a heavy rod which serves as a brace or cross piece between. the frame uprights and which is circular in cross section as indicated by full and dotted lines Fig. 2.

For the .purpose of removing the counters should theynot readily drop off the form, any well known device may be employed. A counter removing device is not however, essential, as the operator may readily remove the counters from the form as it comes into position to engage with the next blank. The shaft Z which carries the cam wheels m and the disks f are provided with a gearp which is in mesh with the large gear I) which is driven from the pinion a on the shaft 0, the

shaft 0 being driven by means of the gear I) usual manner of feeding similar machines,

the operator sitting in front of themachine, picking up a flat blank, bending it into the proper shape with his fingers and holding it on the form 6 until it has been seized by the dies f.

The automatic feeding mechanism which I have provided is arranged as follows:--'lhe flat blanks are placed one on top of the other in a box or receiver shown at a which is of the proper size to receive them. Thebottom of thisbox is slotted so that only one blank at a time can be slid out of it, the arrangement being substantially the same as is em; ployed in card cases and the like which permit of one card being withdrawn at a time. For the purpose of withdrawing or sliding out the bottom blank of the pile in the box a an arm I), which is provided at its free end with a flexible or spring finger 0 is mounted on a rock shaft 01 which is journaled 'on the side of the frame. At the rear end of the rock shaft (1 is an arm a which engages a cam f cut in the periphery of a wheel which is mounted on the end of the shaft 0. As the shaft 0' revolves the rock shaft (1 will be moved, causing the flexible finger to engage with and move the bottom blank in the box or receiver a forward between the-feed rolls The blank is then carried forward by the feed rolls which feed it forward onto a support or table 77, on the front of the machine. It is now in proper position with reference to the form 6 but is in front of the path of the form and requires to be moved toward the form carrier into the path of the form. For the purpose of accomplishing this, the table h is slotted transversely at two points as with a roll n which is in the path of the cam shaped block 12 which is secured on the face of the gear b. As the gear revolves the block 19 engages the roll a on the arm m throwing the arms k rearwardly, and slidingthe counter blank a into the path of the form e where it is held upon suitable projections. As soon as the gear I) has moved a given distance the cam-block p clears the roll a and allows the arm "in to drop back thus returning the arms 7& to their normal position in readiness to move forward the succeeding blank. By providing a sufficient number of cam blocks 19 and placing them in proper positions on the face of the gear I) the feeding arms 10 may be operated as frequently as desired. The feed rolls 9 are operated by means of a train of gears 01, 11 c and d Figs. 1 and 2 from 'the shaft 0 which is provided at its rear end with a beveled gear d which is in mesh with the beveled gear f mounted on the shaft 0.

On the shaft of the pinion a is mounted a rollf which is in frictional contact with the roll 9 which is in turn in frictional contact with the rolls h which drive by frictional contact the lower feed rolls 9 as will be clear from Fig. l.

The roll f is driven at a relatively high rate of speed and operates to burnish the counter blank as it passes through the feed rolls in being fed forward onto the table or support h. This feature may or may not be employed but I consider it of importance.
