JOHN S. HANSEN, OF BROGKTON, MASSACHUSETTS, ASSIGNOR TO O. A. MILLER TREEING MACHINE COMPANY, OF PORTLAND, MAINE, A CORPORATION OF MAINE.

SHOE-FINISHING MACHINE.

Specification of Letters Patent.

Patented May l5, 1908.

To all whom it may concern:

Be it known that I, JOHN S. HANSEN, a citizen of the United States, residing at Brockton, in the county of Plymouth and Commonwealth of Massachusetts, have invented certain Improvements in Shoe-Finishing 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 machines for finishing shoes and particularly to machines for treeing orvironing shoes.

The invention is herein shown as an improvement upon the shoe ironing machine shown in a prior application for Letters Patent made by me February l, 1905, Serial No. 243,690.

An important feature of this invention consists in providing in an organized machine means for treating successively different portions of a shoe. It has heretofore been attempted to tree or to iron all the portions of a shoe at the same time. It appears, however, to be impractical to give simultaneously to the several tools that are required for treating the Whole shoe the movements which enable them to cover the shoe Without interfering With one another or else leaving parts of the shoe imperfectly finished. In accordance With this feature of the present invention. an ironing machine is provided With means for treating the sides and fore part of a shoe at one time and With means for treating the back or rear part of the shoe at another time.

Another feature of the invention consists in providing means for finishing the back of a shoe by tools which reciprocate over the shoe in the direction of its height. This has the great advantage that the tools move lengthwise of the back seam of the shoe, or the back stay with which shoes are generally provided at the present time, instead of across this seam or stay. By so doing the tools rub down the seam and finish the stay Without any tendency to open the seam or dis lace the stay, as is liable to be done by too s moving transversely across the back of the shoe. Preferably rolling tools are eniployed for iinishing the back of the shoe rather than rubbing tools, as the former have less tendency to pull the seam...

A further feature of the invention consists in the combination of tools arranged to treat the fore part and sides or the vamp of a shoe by moving over the upper lengthwise of the shoe, with other tools arranged to treat the bacia stay or similarly located rear portion of a shoe by moving over it in the `direction of the height of the shoe. These tools or groups of tools preferably engage the shoe at different times so that no interference results from operating them in different directions.

Another feature of the invention consists in the construction and arrangement of the tools for treating the back stay or rear part of the shoe. rihese tools Will be herein re ferred to as the back stayH tools for con venience in distinguishing them from the tools which treat the fore part and sides of the shoe. These tools preferably include rolling members arranged to engage the shoe at either side of the middle of the back and are sup orted to enable them to separate more or ess for adapting their position to the varying shape of the different portions of the surfaceof the shoe and to the shape of differently formed shoes. These tools are herein shown as saucer-shaped disks having Worl engaging faces formed on their inclined marginal portions. The tools are mounted to turn on supports which maintain them normally With their adjacent edges substantially together, but permit them to be separated or wedged apart by the Work against the tension of the spring. These tools preferably also include a member, shovvn as a roll arranged between and overlapped by the firstmentioned tools to engage the upper along the middle line when they are spread apart. This roll is yieldingly supported so that engagement of the three members With the Work may take place throughout substantially the Width of their acting faces and the back stay or similarly located rear part of the shoe be smoothed. These tools, `like the tools acting on the fore part of the shoe, are

referably heated when used for finishing leather that is not greasy, and when heated they serve to iron the shoe.

A further feature of the invention consists in novel mechanism for controlling the operation of the back stay tools by moving them into and out of operative relation to the shoe in time relation With other movements of the machine and Without requiring special attention from the Workman.

These and other features of the invention,

including certain details of construction'and combinations of parts, will. be full y explained in the following description of the preferred construction embodying the invention and then will be particularly l'iointcd out in the claims.

Figure 1 is a side elevation of the machine. Fig. 2 is a plan view, partly in section. 3 is a perspective view of a mechanism to be described. Fig. 4 is a side elevation of the back stay ironing mechanism. Fig. 5 is a perspective view of the back stay ironing devices.

The construction embodying the present invention is herein shown as applied to an ironing machine illustrated in my prior application and as cooperating with certain mechanisms of that machine. The complete machine is therefore `shown in the general views and will be sufficiently described to make plain the relation of the new mechanism to the entire machine.

The frame 2 of the machine is supported. at the front end by a post 4 and at the rear end by a large tubular column 6. The frame has bearings at the front end for the vertically reciprocating shafts 8 which carry the tools for operating upon the vamp of the shoe. The column 6 supports a turret carrying a plurality of trees 10 to which the shoes are applied for presentation to the devices for treating the upper. Each tree-carrying arm of the turret is notched as at l2 for engagement with a latch 14 that loclis the turret with each of the trees in a predetermined angular position. The latch is acted upon by a spring 15 to hold it in engagement with the notch 12 and a lever 16 is provided for rocking the latch in the direction to release the turret and permit it to be rotated. One of the trees is stopped by the latch in operative relation to a lever 18, by wliich the tree is expanded. This lever is actuated by a bell crank pivoted near the base of the column 6 and having its horizontal arm overlying a lever 22 in position to be rocked by it. The driving mechanism comprises a pulley shaft 25 connected by intermediate gears with a crank shaft 26 and a cam shaft 28. The crank shaft is connected by a link 30 with the lever 22. This lever is flexibly connected with a cross head 32 to which are fastened the lower ends of the shafts 8. By this ar rangement the shafts are continuously reciprocated upwardly and downwardly for giving to the tools carried by them the move ments required for treeing or ironing the shoe. The shafts 8 are arranged to turn from the position shown in Fig. l, wherein the tools are out of contact with the shoe, to swing the tools laterally toward and into co tact with a shoe positioned between them. This turning movement of the shafts for swinging the tools toward and from operative position is eifected by the engagement of pinions 35 carried by the shafts with rack teeth formed on the opposite edges of a rack bar 36, see F i l'. 2. This rack bar is fas tened to a rod 38 t iat movable endwise of the machine, being actuated to tho left in Figs. l and 2 by the spring 40. The rod and rack bar are reversely actuated for swinging the tools into operative position by thc lever 42, which is rocked forwardly and backwardly by the cam 41% and spring 44. The end portion 45 of the rod 38 adjacent to the lever 42 is pivotally connected to the main portion of the rod and is normally held, as shown in Fig. 2, in a position. out of aline ment with. Vthe lever.

A pair of levers 45, 47 is arranged for movingI the end piece 45 intl alinement with the lever 42 when it is desired to swing the tools into operative relation to the shoe. A catch 48 fastened to the rack bar, as shown in Fig. 3, engages with a catch 4Q on the frame to maintain the rack bar and the tools in the position to which they are moved by the lever 42. Provision is made for lifting the catch 48 and thus permitting` the movement of the rack bar under the influence of spring 40 to swing the tools away from the shoe after the tools have made a predetermined number of reci rocations over the shoe. To this end a shat 5() has a projecting arm 52 underlying the catch 4S and a crank 54 on its outer left-hand end, as shown in Fig. 3. This crai'ik stands in the path of an arm 55 on a ratchet having its toothed periphery in the path of a plunger` 56 that is carried by one of the shafts 8. A weight or suitable spring, connected to the chain 58, normally moves the ratchet and its arm in the direction of the arrow thereon until the arm rests upon the stop pin 59, which may be positioned in any one of a series of holes in the side of the frame, according to the desired number of the reciprocations of the tools in contact with the shoe. .lt will be underL stood that when the tools are swung into their inoperative position the plunger is carried away from the ratchet and that after the tools have been moved into their operative position the plunger turns the ratchet through a predetermined distance for each reciprocation of the tools until the arm 55 has engaged the crank 54 and through the action of the arm 52 has lifted the latch 48, whereupon the shafts S and the tools are swung into their inoperative position by the spring 40. The spring or weight attached to the chain 58 then returns the ratchet into its initial relation to the stop pin 59. The shaft 50 has a hand piece 60 by which the latch 48 may be lifted to permit the movement of the tools away from the shoe at the will of the operator.

The mechanism for treating the back stay or similarly located portion of the shoe is arranged in an angular position to treat the shoe that is between the one being finished by the fore part tools above described and the tree which is in position to be expanded by the lever 18. The hack stay treatii'ig mechanism is supported on a lever 7() fulcrun'ied on a bar 72 pivotidly connected to the fraine of the machine. rl`his bar carries a roll 73 that rests upon a cam 7d which determines the vertical. position of the mech anisni. The lower end of the lever is con- .ieoted by the linl; 7 5 with a bell crank lever 7G, the horizontal arm of which e tends into position to be ei'igaged by the ve ically reciprocating lever 2; or a plate carried by that lever. A spring 77 holds the bell cranli in contact with lever 22 and together withthat lever produces an oscillation of lever 7U about its connection with the bar 7 rThis oscillation of lever 7 0 carries the bach stay treating tools 'forth and back lengthwise of the back stay between the top and bottonrof the shoe, as shown in Fig. 4. 'ihe link 75 supports block on which is n'iounted a pawl 7 8 which is held by a spring S() in position to engage ratchet teeth on a disl; fast to a cam 74.-. rlhe ratchet wheel has one tooth 83 which is longer than the extent of nieveinent imparted to the paWl '78 so that While the paWl is in engagement with tooth S3 it will slide forth and bach Without turning the ratchet or the cani. rlhis tooth is in position to be engaged by the pavvl While the roll 73 rests in the low part of the cam 7 4 and the baelr stay treating mechanism is therefore in vinoperative relation to the shoe and below the plane in which the trees travel in the movement of the turret. A pan/'l S4 holds the ratchet against backward movement This pawl is slidingly supported on the stud and by means of the pin 86 and linlr 87 is arranged to be moved forwardly by the hand lever 16. This lever, it will be recalled, is the device for moving the latch le out of the notch 12 to permit the turning` of the turret. The forward movement of the pavvl turns the ratchet to carry the long tooth past the pawl 78 and thereafter with each reciprocation of the pau/l 7 8 the cani 7 4 will be advanced one step and by its engagement with the bar 7 2 it will raise the back stay treating tools into operative relation to the shoe to be treated by them. rlhe cam 7 4- raises the tools a definite distance and if it is desired to vary this elevation for different sizes of shoes or to vary the pressure of the tools on the Work the link 75, which is extensible, is adjusted by the part 79.

The back stay treating tools are yieldingly supported on the lever 70 by means of a earrier 90 pivotally connected to the u per end of the lever and yieldingly held by t ie spring 91 in a position determined by the adjusting screw 92. These tools comprise three menibers, the outer ones, 93, 93, being shaped somewhat like inverted saucers and mounted to turn upon axes arranged substantially per endicular with relation to the adjacent surface of the shoe7 shown in Fig. 4t. rlhese axes or 'pivots are carried on the rear ends of arms 04 mounted on. studs 95 that project ujim'ardly from the carrier Q0. A spring Q6 yieldingly draws the tools SH3 together, holding them. normally with their edges in contact or substantiall-y in contact,

shown in Fig. 5. 'l he third tool, Q7, is arranged. between the tools 9.5 and is mounted to turn on an axis substantially parallel with the adjacent surface of the shoe. Vv'hei'i the back stay treating tools are to be used upon dry upper stock or upper leatller that is not too greasy they will be heated a gas burner CIS provided with a she lfhe construction and arrangement er the back stay treating tools as described is such that when. they are lifted by the cam. 74 into contact vrith the shoe the tools 93 are forced. apart and exert a lateral spreading action on the back stay or other portion of the shoe engaged by them, and they are reeil'irocated forth and bach over the stay the movement of their marginal acting surfaces is in the direotion to exert an outward sineotl'iing action upon the edge portions of the back stay. The spreading of the tools 93 permits the engagenient of the tool 97 With t ie middle portion of the back stay, or in the treatment of shoes having a single seain at the haelt this tool 97 engages and srnooths this seam while the tools 93 exert a more vigorous smoothing action upon the portions of stock adjacent to the seam.

In the use of the machine, the trees on the turret having been provided Ywith shoes and expanded, the turret is moved to position one shoe opposite the forepart treat-.ing tools and another shoe opposite the bach stay treating tools. At the saine time a third shoe dll be brought into position adjacent to the expanding lever 18. In order to effect this nioveinent of the turret the latch. le is retracted by the hand lever 16, the lever holding the latch out of the notch. l2 in the tree While the turret is being rotated. This saine rnov ement of the lever 16 which withM draws the latch also shifts the pavvl for turning the ratchet to carry the long tooth 83 past the pavfl 78. The low part of the cani 74 will preferably be so formed and posi.- tioned that the back stay treating tools will not be lifted immediately after the cani. is started but time will be allowed to insure that the shoe to be treated will reach operative position before the tools are lifted. At the next oscillation of lever 22 the cani 74 will be turned in the direction to lift the back stay treating tools into operative relation to their shoe. The lever i7 will be shifted for putting the end piece 45 of rod 38 into position for that rod to be'actuated and the shaft 8 thereby turned for moving the fore part treating tools into operative relation to-the 'lore Apart ol" the shoe. Therea'lter during successive oscillations oit the lever the two sets oi tools will be moved lforth and back over the shoe, the 'hire part treating tools moving in the direction oi the length olI the shoe and the back stay tri-ratingI tools moving in the direction ol' the length of the back stay. '.lhese movemel'its will conti'iiue until the 'loro part treating tools are returned to their inoperative position by the tripping mechanism sl'iown in Fig. 3 and the back stay treating tools are lowered out ol operativi-i relation to their shoe by the arrival oi: the low part of the cam 74 under the roll on the har 72. The sets of tools will then be positioned out oil the path of travel ol the trees so that the turret may move for presenting other slices in position to be treated. It will be observed. that the arrangement is such that each shoe is treated successively tirstfby the back stay ironing tools and then by the 'fore part ironing tools. The bark stay ironing tools areJ caused to become operative by shitting the lever 16, while the fore part ironing tools are caused to become operative by shifting the lever 47. This provision enables one set of tools to be used without the other when that is desired. This is of advantage in startingI work with the machine for at that time it is desirable to iron the first shoe with. the baci: stay treating tools before any shoe is put into position to be treated by the tore part ironing tools. 'lhereiore in the :first use ol the machine the back stay ironing tools only are used. Of course in iinishing the last shoe the fore part ironing tools only will be used, the back stay ironing tools remaining idle.
