SPECIFICATION forming part of Letters Patent No. 536,352, dated March 26, 1895.

Application filed-January 3 1 8 95 To all whom, it may concern:

Be it known that we, EDWARD C. J'UDD, of Boston, in the county of Suffolk, and ABNER O. PAUL, of Lynn, in the county of Essex, 5 State of Massachusetts, have invented certain new and useful Improvements in Sole-Laying Machines, of which the following is a specification.

This invention relates to machines for apxo plying pressure to a sole laid upon the portions of the upper of a boot or shoe that project over the bottom portion of the last, and maintaining such pressure while the cement which has been applied to the contacting surfaces of the sole and upper is setting or hardening, the object being to temporarily secure the sole to the upper preparatory to the permanent attachment of said parts by stitches or other fastenings.

The invention has for its object to provide an improved construction of the platen or presserwhich bears upon the outer surface of the sole during the pressing operation and co-operates with the jack which supports the lasted upper in securing the desired intimate contact between theinner surface of the sole and the upper.

The invention also has for its object to provide improved means in a power-operated 3o machine for bringing the upper and sole into contact with each other before the power of the machine is applied to complete the pressure.

yTo these ends, the invention consists in the improvements which we will now proceed to describe and claim. l

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a vertical central section of a machine em- 4o bodyingourimprovements. Fig.2represents a section on the planeof line 2 2 of Fig. l,

and a plan view of portions of the mechanism below said line. Fig. 3 representsA an elevation of a part 0f the jack-raising mechanism shown in Fig. 1. Fig. 4 represents a perspective view of a portion of the jack. Fig. 5

represents a sectionaly view of a portion of` the machine on a largerrscale than shown in Fig. l. Fig. 6 represents an enlargement of 5o a portion of Fig. 5. Figs. 7 and 8 are diagrams showing the foot-power actuated means Serial No. 533,767. (No model.) l A' for raising the jack into contact with the presser or platen. Fig. 9 represents a sectional view showing a different construction of the means for supporting the presser or platen.-

The same letters of reference indicate the same parts in all the figures. y In the drawings, a represents the supporting standard or pedestal of the machine, upon 6o which is mounted to rotate horizontally a, frame carrying the sole-pressing and shoesupporting devices hereinafter described, said frame comprising a vertical tubular portion b, a base portion b,and a top portion or head 65 b2. The rotary frame is provided with a plurality of jacks which support the lasted uppers of a series of boots or shoes, and with a plurality of sole pressers or platens which co-operate with the jacksand the lasts thereon 7o in pressing the cement-coated soles against the cement-coated uppers; and as all the jacks and pressers or platens are alike, we will describe the construction and mode of operation of one jack, and the accompanying presser or platen.

The head b2 is provided with a springv pressed coupling or joint member c, which'is movable vertically in a guide or socket b3 forming a part of said head, and is pressed 8o downwardly by a spring c bearing at its upper end on a shoulder in the socket b3 and at its lower end on the coupling member c.- The under side of the coupling member is concave, and constitutes a seat upon which bears a coupling or joint member d formed on the `platen or presser, said coupling member d being convex and constituting with the coupling member c the equivalent of a ball-andsocket joint which permits a free oscillating go movement of the sole-presser or platen not p only lengthwise but crosswise. 1n other words, the said presser or platen has a universal tip- Y infr motion. Y

The presser or platen is composed of a holder d upon which the coupling-member CZ is formed, a sole-pressing pad d2, and a heelpressing pad d3 affixed respectively to rigid back-pieces d4 d5 which have dovetailribs d, by means of which they are detachably afroo fixed tothe holder. The rib d6 of the heelpressing pad d3 is engaged with a dovetail groove formed in the holder d', while the rib of the sole-pressing pad is engaged with a dovetail groove formed in an arm C27 which is adjustably connected to the holder, in order that the sole pressing pad may be given various inclinations although at all times rigidly connected with the holder, said arm d? being pivoted at d to the holder and engaged at its outer end by a ball-andsocket joint with a screw-threaded adjusting-rod al which works in a spherical nut d10 contained in a socket d12 formed on the holder d. By rotating said rod d, the outer end of the solepressing pad cl2 may be raised or lowered, as the ease may be, and said pad thus adjusted to the curvature of the toe portion of the last, the toe being higher in some lasts than in others. Vile do not limit ourselves to the employment of an adjustable sole-pressing pad, however, and may attach the said pad to the holder in the same manner that the heelpressing pad d3 is attached, the two pads being in all cases rigidly attached to the holder and incapable of independent yieldingr or selfadjusting movement excepting such movement as may be due to the elasticity of the pads themselves, the latter being preferably comparatively thick blocks or pieces ot' rubber fixed to the backs d4 d5.

It will be seen that the spring c exerts a downward yielding pressure upon the coupling-member c, and through the latter upon the presser or platen, the latter being therefore adapted to yield bodily to the pressure exerted against it by the jack, as hereinafter described, this yielding movement of the presser or platen enabling it to conform to the thickness of the sole and the size ot' the last interposed between it and the jack.

To limit the yielding movement imparted to the presser or platen bythe spring c', We provide a stop e, which, in the construction shown in Figs. l and 5 is a collar having a` convex upper surface tting the concave under side of the coupling-member d. Said collar e is provided with a tubular stem or shank e,which extends upwardly through the socket b3 and constitutes aconnection between the stop e and the head b2 which rigidly supports the stop and causes it to support the presser or platen against the downward pressure of the spring c', said stop permitting the yielding movement of the presser or platen. We prefer to make the connection between the stop and the supporting-frame adjustable, so that the stop may be depressed `or raised to Vary the initial position of the presser or platen from which its yielding movement commences. To this end, we have shown in Figs. l, 5,and 6, an internally screwthreaded nut or bushing e2 fitted to rotate in a socket formed in the head b2 and engaged with an external thread formed on the tubular stem e', said bushing c2 being provided with a hand-wheel e8 by which it may be rotated to raise or depress the tubular stem c and stop c. YVhen the said stem and stop are depressed, the spring c forces the presser or platen downward, so that its normal position is lower than before; and when the stop is raised, it raises the presser or platen with it, the spring c' yielding, so that the normal position of the presser or platen is higher than before.

The holder d is formed so that the sole and heel pressing pads are separated from each other by an intervening space ot" snliicient width to receive a shank-presser, which is composed of a rigid holderf and a pad or stripf aflixed thereto and formed to bear upon the shank portion of the sole. The shank-presser is supported by a rod or stern f2 the lower end of which is affixed to a block or head f3 to which the holderfof the shankpresser is connected by a segmental ribf4 tixed to said holder and entering a segmental groove formed in the head f3, said rib and groove being arranged to permit the shankpresser to tip or rock erosswise ofthe sole. The shank-presser does not partake of the oscillating movements of the sole and heelpressing platen above described, but is adjustable vertically independently of said platen, soA that it can be depressed to any desired distance below the surfaces of the sole and heel pads, and thus act to confine the shank portion of the sole against the corresponding portion of the upper before the pads d2 and dis act on the fore-part and heel portions of the sole. The shank-presser and its rod f2 are subjected to the downward pressure of a springf5 which bears upon an adjusting nut f which is engaged with a screw-thread on the upper portion of the rod f2, said spring being supported by a yoke or framef7 secured to a suitable support such as a handwheel c3. The spring f5 holds the adjusting nut]c6 against a suitable support or bearing, which as here shown is the upper end ofthe bushing e2 above described.

The adjusting nut uf has a hand-wheel]ES by which it may be rotated to raise or depress the rod f2 and the shank-presser. The shank-presser can therefore be adjusted vertically independently of the sole and heel pressing platen, and is at all times yieldingly support-ed, the yielding support being due to the spring f5 when the shank-presser is adjusted, so that its head j"3 is separated from the stop e. Vhen said head f3 is brought in contact with the stop c bythe yielding of the spring f5, the shank-presser partakes with the sole-pressing platen of the yielding movement permitted by the spring c and the sliding coupling-member c.

It will be seen that the presser composed of the heel and fore-part pads affixed to an oscillating holder common to them both, said holder having also a yielding `movement, and the shank-presser adjustable independently of the heel and fore-part presser and having an independent yielding movement as well as a yielding movement in common with that of the heel and fore-part presser, constitutes ICO TIO

a simple and eective means for co-operating with a jack in pressing a sole against the lasted upper and maintaining the pressure while the cement is setting or hardening.

We do not limit ourselves to the details of construction above described, and may modify the same without departing from the spirit of our invention.

In Fig. 9,/we show a modification in which the coupling-member on the holder d is a socket du, and the spring-pressed couplingmember is a ball dw, the adjustable stop which limits the downward movementl caused by the depressing spring d17 being a sleeve C118 having a flange at its lower end adapted to support the sliding part C119 on which the ball dl is formed. The sleeve du is adjusted by means of a nut d10 engaged with a screwthread on the exterior of said sleeve.

The jack comprises a base portion h having a telescopic standard h provided with a toe-rest h2, and a slide h3 having a standard h4 provided with a spindle h5 formed to enter the socket in the heel portion of the last, vthe slide h3 being adjustable by means of a screw h6. The jack is suitably engaged with a jackcarrier fi, which is vertically movable on the supporting frame, and is moved vertically to apply and remove pressure by means of a power mechanism which comprises togglelinks j j connected respectively to the jackcarrier and to a power-driven gear-wheel k which rotates with the supporting-frame on the standard a, and a cam m affixed to the standard a and formed to be engaged by an ove'rhanging trundle-roll t7'2 connected with the meeting ends of the linksjj. The trundle-rollj2 is mounted on a frame or holderj3 which is connected with the linksjj and is provided with a trundle-roll j* bearing on the outer surface of the cam m, the trundle-roll .i2 bearing on the inner surface of said cam.

The cam is formed to simultaneously hold the links'of all the toggle-joints in alignment with each other, thus elevating the jack-carriers excepting at one point, where the meet ing ends of the links are thrown inward, thus depressing the jack-carrier and jack, as shown at the right in Fig. 1, so that the jack-carriers and jacks are elevated at all points excepting at one side of the machine, each jack-carrier and jack being depressed when it reaches said point, which is the operators station. vided with two cams n n aftixed to a rockshaft njournaled in bearings in the jack-car- Eachjack-carrier is pro-` nary upward movement, so that the operators hands are left free to attend to the other parts of the mechanism.

o represents a vertical rod located in the standard a and connected at its lower end to a treadle by the loperation of which the rod may be depressed, the rod being normally raised by means of a spring o. On the upper end of the rod is formed an arm or hook o2 which is in position to engage a lug p' formed on a slide p2 which is movable in a slot p3 formed in the tubular portion'b of the supporting frame. The slidep2 is connected by means of a link p4 with an arm'ns affixed tothe rock-shaft n. When the jack is depressed and the cams heldy by the weight'of the jack in a depressed position, the slide p2 is elevated by the `connection betweenit and the cams, and is in position to engage thc hook o2, so that when the `said hook is depressed by a movement of the treadle, the rock-shaft 'n' and cams 'n will be turned to raise the jack independently of the jack-carrier. A segmental ratchet q is affixed to the jack-carrier in position to engage a springpawl q on the arm ns, said ratchet and pawl locking the cam inl its jack-raising position, as shown in Figs. 3 and 4.

1t will be understood that as the supporting frame rotates on the standard a, the slide p2 connected with each jack carrier is raised when the jack-carrier is permitted to drop by the action of the cam mand the toggle-links, as above described, so that said slide is in -position to be engaged by the hook o2 and operated to raise the jack after the operator has removed the completed shoe and applied an-A other to the jack. I.The operator is therefore enabled to change the position of the jack by foot-power.

The diagram shown in Fig. 7 shows the positions of the slide, cam, andv treadle before the jack has been raised by the depression of thetreadle; and the diagram shown in Fig.v

8 shows the position of said parts after the jack has been raised by the depression ofthe treadle. f
