MACHINE FOR FINISHING HEELS OF BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 396,620, dated January 22, 1889.

Application filed February '7, 1888.

' connection with the accompanyingdrawings,

representing like parts.

is a specification, like letters on the drawings This invention has for its object the production of a machine upon which to perform in succession several operations, all tending toward the completion of a heel, one operation taking place automatically after the other-as, for instance, the heel of one shoe being trimmed and welted while another is being scoured and the third breasted, and the successive operations taking place simultaneously, the mach inehaving a series of jacks, the number of which is one more than the number of simultaneous ope rations, to thereby enable the operator to take off a shoe having a finished heel and apply to the machine another shoe the heel of which is to be trimmed and subsequently treated without stopping the operation of the machine or of various tools acting upon a series of heels of shoes held in place upon the remaining jacks.

My invention in machine, for treating the heels of boots or shoes consists, essentially,

in a shaft capable of sliding longitudinally in 3 bearings or boxes secured to the frame of the machine and a plurality of jacks secured thereto, combined with a plurality of tools to act on the heels of the boots or shoes held by the said jacks, gearing, substantially as will be described, to operate said tools, and with lifting devices to move each rotating tool away from the heel being treated preparatory to moving the said shaft longitudinally in order to enable the jacks to be rotated, whereby a jack containing a shoe which has been acted upon by one tool may be brought into position to be acted upon by a second tool.

Other features of my invention will be pointed out in the claims at the end of this specification.

Figure l. is a top or plan view of a machine containing my improvements. Fig. 2 is a de tail to the left of the section-line 001;, Fig. Fig. 3 is a side elevation of the machine Serial No. 268,305. (No model.)

shown in Fig. 1; Figs. 3" and 3 details to be referred to. Fig. 4c is a sectional detailin the line at, Fig. 3, looking to the left. Fig. 5 is a sectional detail in the line 1', Fig. 3, looking to the right. Fig. 6 is a sectional detail in the line 00 Fig. 3, looking to the left, the shaft D and guide-arm D being in position opposite to that shown in Fig. 1; Fig. 7, a like section looking to the right.

The machine herein shown as embodying my invention has a bed-plate, A,upon which is erected suitable standards or uprights, as A, A A A, and A, to support the working parts. The power-shaft B has fast upon it, outside the frame-work, usual fast and loose pulleys. This shaft carries a pulley, B, which drives a belt, B extended over a pulley, B rotating a short shaft, 13*, free to slide to a limited extent in bearings 13, the said shaft having secured to it between its bearings a grooved collar, l3, which is embraced by a yoke, B having stud, B which, extended through a spring, as B, is jointed to the upper end of a lever, B having its fulcrum at B on a stand, B the lower end of the said lever having a cam or other project-ion, as 2, (see Fig. 3,) which is acted upon by a cam, as B attached, to the main shaft (1 of the machine.

The short shaft B has secured. to its inner I end a sleeve or collar, as (1-, (shown separately in Fig. 3,) provided with two lugs or cars, as a, and the right-hand end of the shaftD has fastened to it by a suit-able screw a like collar, a2, having like ears, and each of these cars receives through it a screw, as 3, having a point, the four screws entering the four sides of a square block, as a (shown separately in the detail, Fig. 3 the two collars, the block, and the screws forming a universal joint or connection between the shafts B and D of very great strength, the chief strain between the shafts being taken by the ears and the block, rather than by the screws, as in ordinary forms of universal joint.

The shaft D is extended through a slot in a gear, D, and thence through a bearing or bvx, as D which is free to slide in a guide arm or yoke, D connected with the hub of the gear D, the said bearing or box being acted upon by a suitable spring, 4, surrounding a guide, D The shaft D beyond the bearing D and toward the jack to be described is provided with a conical or tapering sleeve, as D which will be attached thereto in an adjustable manner. This conical sleeve bears against a pattern-plate, as D, made fast to the upright A", it being of such shape as to constitute a former to act as a guide for the shaft D and its attached heel trimming and welting tool D which is and may be of any usual shape, it being attached to the shaft in any usual manner and carried about the heel to be trimmed from breast to breast, the adjustment of the said sleeve upon the said shaft enabling the operator to adapt the trimming-tool to heels of the same shape, but varying in size, and also acting to cause the trimming-tool to approach more or less the center of the heel as the shaft D is moved longitudinally. As the shaft I), referred to, is being rotated, it is also carried about the heel from breast to breast by and through the guide-arm D and the gear D driven by gearing, as will be described, the spring 4:, referred to, during such motion of the shaft 1) about the heel being trimmed, through its action on the box or hearing D keeping the sleeve D referred to, against the pattern plate or former D.

The machine shown contains four jacks, b b 19 19 all radiating from a common sleeve, 2'), secured to a shaft, as I), by a set-screw, as 1)", (see Fig. 4,) the shaft If being mounted in bearings 12 b fixed with relation to the framework and being free to both slide and rotate therein, it being free to slide when the stoplever Z)" is lifted from between the bearing 11" and the end of the sleeve Z), (see Fig. 1,) and being free to rotate when the disk 1) fixed to the said shaft 1), has been moved, as to the left in Fig. 3, far enough to remove it from contact with the pin 1), the said disk having in practice as many holes through it as there are jacks, the sleeve containing all the jacks being rotated by hand, so as to bring one jack into position after another when the disk 1) is disengaged from the pin 1). Each jack consists, essentially, of two arms, one of which contains a clamping-screw, as 6 while the other arm contains a rest or seat, I), for the outer end of the heel, the arms carrying the said seats being provided with openings, as I), (see Fig. 4,) to permit the passage therethrough of the heel-breasting knife, to be de scribed, as each shoe, having been treated, arrives in position to be breasted.

One of the arms of each jack also has attached to it guiding-arms, as b, preferably made as springs, between which are tapering spaces, to thus receive between them and clamp the shoe at each side at or near its toe, to thus constitute guides to hold the shoe true with relation to the jack, in order that the heel may be breasted square across, or at substantially right angles to the length of the shoe.

The bearing b referred to, receives upon it an elbow-lever, 5 (shown best in Fig; 5,)

which, when the stop-lever Z), before referred to, is lifted to permit the jack to be moved longitudinally, acts through intermediate mechanism, to be described, against the rotating toolshafts D and E to move them out of the way of the arms of the jack, said elbow-lever and stop-lever forming part of a stopping mechanism, the other parts being a lever, as 0, (see Fi 2,) pivoted at c, and having attached to it a link, jointed to a spring-actuated lever, c, pivoted at c, the opposite end of the lever having pivoted to it a link, 0 which is attached (see Fig. 5) to one arm of the elbowlever 12 During the outward movement of the shafts referred to by the elbow-lever b the spring 4: above the bearings or boxes in which the said shafts are held is compressed, and as soon as the jacks have been returned into operative position and the stoplever b brought into position between the end of the sleeve of the jack and the bearing 11 the spring b attached to the lever 0 comes into operation and positively returns the elbowlever Z1 into its normal position.

The power-shaft B has upon it a pulley, E, which, by a belt, E extended over a pulley, E fixed to a short shaft, E rotates through a universal-j oint connection the shaft E, before referred to, the latter shaft at its forward end being provided with a scouring tool or wheel, E, if the heels are to be first trimmed and then scoured and thereafter breasted.

The universal-joint connection between the shaft E and E is just the same as described between the shafts B and D, and in practice the shaft E is extended through a slot in a gear, E, mounted upon a suitable stud on the upright A the hub of the said gear having an attached forked arm or yoke, E in which slides a box or bearing, E acted upon by a spiral or other spring, as E", the function and purpose of which are to keep the said shaft against the pattern-plate or former E so that as the said shaft with the scouring-wheel E attached is rotated it is also carried about the said former and about the heel from breast to breast, it scouring the heel of one shoe while the cutting-tool before described is trimming the heel of another shoe, or it may be trimming and welting the heel of another shoe. The power-shaft B also has fast upon it a small pulley, F, which, by a belt, F, eX- tended over a larger pulley, as F fast on a shaft, F rotates the said shaft, it sustaining a toothed gear, as E, which constitutes the driving-gear .for the series of gears to be described, which rotates the two gears D and E, before described.

The toothed driving-gear F", referred to, engages an intermediate gear, (Z, loose on a stud, (Z, secured to the upright A, the said stud at the rear of the loose gear (1, supporting a sleeve, (1 having an arm or arms, (1 upon which are pivoted two gears, as (1 (I the loose gear (1 engaging and driving positively the gear (1 the gear (Z in turn engaging and r0 tating the gear (1", the gear (Z rotating in one and the gear (1" rotating in the other direction at the same speed.

Between the slotted gears D and E is an intermediate gear, (1, mounted upon a stud, (F, the gear (1 being in turn engaged by an intermediate gear, (i loose on astud, disapported in a bracket, (1 attached to the uprightA. The sleeve (1' has at one end an arm, (l/ provided with a toe, d This arm is jointed to a link, (1 carried upward and connected to an elbow-lever, (1, pivoted at d, the upper end of the lever being extended up within the range of movement of the slotted arm or yoke I). link (1 is connected by rod ewith a treadle, e.

The screw (Z serving as a fulcrum for the elbow-lever, (1, also supports an elbow-lever,

6 one end of which is turned upward and also left in the range of movement of the slotted arm or yoke D, the said end being bent in a direction opposite to that of the end of the lever (1, so that when the slotted arm or yoke moves in one direction, as indicated by arrow 25, Fig. (1;, it at the end of its stroke meets the upper end of the lever e and at the end of its stroke in the opposite direction the upper end of the lever d.

The lower end or arm, e, of the lever c has two notches, (see Fi (3,) number one of which engages the toe (Z of the arm (Z when neither of the two gears or d is to engage the intermediate gear, 11*. The second notch in the arm a engages the toe (7 when the gear d is to engage the intermediate gear, d, and rotate the slotted gears in one direction, as to the right, the treadle at such time being depressed.

Fig. (1 of the drawings shows the parts in the position they will assume just after the slotted arm D has been lin-ougl'ltinto position to act upon the upper end of the elbow-lever e and move it sufficiently to release its notched arm 6 from the toe of the arm (Z this occurring when the stroke of the tools has been completed in one direction. As soon as the disengagement has been effected, the spring f, attached to a stud, f, and also to the end of the lever d, acting through the link (1, referred to, lifts the end of the arm d of the sleeve and immediately throws the gear (1" into engagement with the intermediate gear, (1, as in Fig. 6, when, during the further rotation of the main shaft E the reversal of the gears I) and 11. will be instantly commenced, carrying the tools in the opposite direction around the heel to the starting-poiut, when the slotted arm or yoke 1) acts upon the upper end of the lever (i and pushes it down against the stress of the spring f, and through the link (7 forces the toe (1 down into engagement with the notch number one in the lower end or arm, e, of the elbow-lever e'*, the said lever thereafter acting to again holdthe sleeve (I? and the gears d (1", carried by it, each out of engagement with the intermediate gear, (Z The gears (1 61 the arm cl,

The lower end of the and sleeve (Z to carry them, and the two levers (l e constitute the main parts of whatl shall call the reversing mechanism. The slotted gear E engages a toothed gear, g, fast on a shaft, g, having a toothed wheel, g which engages a larger toothed wheel, g, fast on the cam-shaft C, before described. This cam-shaft at its front end is provided with a cam-hub, G which acts upon a roller or other stud, g, carried at the upper end of a lever, g, to which is jointed the rear end of a carrier, 7L, fitted to slide in suitable guideways, 7b, of a bracket, 71 to the upright A", the said carrier having :nljustably attached to it by a suitable screw, as 10, a breasting-knife, 7L3, the said breasting-knife deriving its movement from the cam-hub (1 the roller 9 being normally kept against the said cam-hub by aspiral or other spring, as 7r.

In. order that the operation of my improved machine may be clearly understood, let it be supposed that the jacks occupy the position shown in Figs. 3 and l and are e1npty-that is, without boots or shoes. The operator now applies a boot or shoe to the jack 1), and when properly fixed on said jack lifts the lever I) from the shaft b and slides or draws the shaft toward the end of the machine-that is, in the direction indicated by arrow 20, Fig. 3until the disk or wheel 11" has been disengaged from the rod or pin 1). The operator now gives the shaft a quarter-turn in the direction of arrow 21, Fig. +L, an d then moves it back into its normal position, (shown in Fig. 3,) thus placing the heel of the bootor shoe on the jack 1) in position to be acted upon. by the trimming and welt-ing tool D and when in this position the shaft is locked or prevented fromrotating by the lever Z), which is turned by the operator to engage the said shaft. The machine is now started and the trinuning and welting of the shoe on the jack b are accomplished, and. while the shoe on the jack 1) is being trim med and welted the operator applies an untreated boot or shoe to the jack b which by the partial rotation of the shaft has been brought into the position previously occupied by the jack 1). \V hen the boot or shoe on the jack 1) has been trimmed and welled, the shaft is given another quarter-turn, as described, thus bringing the boot or shoe on the jack 1: in position to be acted on by the scouring-tool E, while the boot or shoe on the jack If isin position to be acted upon by the trimming and welti n g tool,the said tools being removed from operative position while the shaft is being rotated by the elbow-lever 0 as described. While the boots or shoes on the jacksb Z) are being respectively secured and trimmed and \velted the o 1 )erator applies a boot or shoe to the jack 1), and when the scouring and trimming have been completed the sl'iaft is given another (piarterturn to brin the boot or shoe on the jack b,whieh is now trimmed, welted, and scoured, in position to be acted on by the breasting-kn ife It, the boot or shoe on the jack b which has been trimmed and welted being IIO brought into position to be acted upon by the scouring-tool, and the boot or shoe on the jack 12 being moved into position to be trimmed and welted. While the boots or shoes on the jacks b b b are being respectively breasted, scoured, and trimmed and welted, the operator applies a boot or shoe to the jack 1). \Vhen the operations of breasting, scouring, and trimming and welting have been accomplished on the shoes held by the respective jacks b b 17 the shaft is given a quarter-turn and the boot on the jack b brought into position to be trimmed and welted, that on the jack b to be breasted, and that on the jack 1), which has been successively trimmed and welted, scoured, and breasted, into position to be removed from the machine and an untreated boot or shoe placed on the jack 1/.

The boot or shoe which has passed through the respective operations described may then be placed 011 another machine and burnished and beaded; or the burnishing and beading tools may be substituted for the trimming and scouring tools on the present machine, or the trimming and welting and scouring may be effected on one machine and the burnishing, beading, and breasting accomplished on a11- other machine.
