WELT-BEATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 598,727, dated February 8, 18 98.

Application filed April 28, 1896. Serial No. 589,369- (No model.) i

To all whom it may concern:

Be it known that we, ZAOHARY T. FRENCH and WILLIAM G. MEYER, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Welt-Beating Machines, of which the following description,

in connection with the accompanying drawings, is a specification,-like.letters on the drawings representing like parts.

This invention has for its object to improve the construction of machines forbeating out welts of welted boots and shoes; and it consists, essentially, in the combination of a weltbeating hammer, means for operating it, a table upon which the welt is placed, a movable support therefor, a movable abutment against which said support continuously rests and which acts to resist the blows of the hammer, a treadle, and a treadle-rodconnecting said treadle with said movable abutment. 7

The movable abutment is constructed and arranged to serve as an adjusting device by which the position of the table relative to the hammer may be varied, and as preferably constructed the said abutment has bearings which are at all times directly in the line of thrust of the table-support. As herein shown, the table-support is pivoted to the frame, and the abutment is likewise pivoted to the frame, thelatter consisting, essentially, of a cam of varying radius, so that as it is turned on its pivot it will vary the position of the tablesupport which rests upon it.

Figure 1 shows in side elevation a weltbeating machine embodying this invention; Fig. 2, an end view of the machine, the weltbeating hammer and welt-support or table being omitted; and Fig. 3, a plan view of the welt-support or table.

The welt-beating hammer a is secured to the lower end of a rod or bar a, having its hearings in projecting portions a a of the main framework A, said rod or bar a being movable vertically in its bearings. A sleeve 19 is placed upon or embraces the rod or bar a at a point more or less midway its length, it having a laterally-projecting stud b, and a main rotating shaft 0, having its bearings in the main frame A, has secured to it 'suit-' able driving-pulleys at one endand has projecting from its opposite end a crank-pin c, and a link 19 connects'said crank-pine with the laterally-projecting stud b on the sleeve 12, so that as the shaft 0 is rotated the sleeve 12 will be reciprocated. l

' In order that the reciprocating sleeve may "impart a corresponding movementto the rod orba'ra, we have secured to said rod or bar at a point just above the sleeve b a collar cl, against the lower end of which said sleeve 79 bears, and a strong spiral spring cl encircles said rod or bar a, the upper end of-which bears upon or against the sleeve 19 and the lower end of which bears upon or against adj usting-nuts d turned on a threaded portion of said rod or bar. As the shaft 0 rotates the sleeve b,'acting'upon the spring cl, depresses the welt-beating hammer,and then acting upon the fixed collar d raises said weltbeating hammer.

By connecting the rod or bar a with th means for operating it by means of the loose sleeve 6, fixed collar d, spring cl, and adj usting-nuts d it will be seen that an adj ustable yielding connection is provided whereby the welt-beating hammer will deliver a succession of yielding blows.

6 represents the table upon which the welt to be beaten out rests, and it is herein shown as having a tapering lip adapted to enter the crease or inseam or bear against the last at i the face side of the welt.

The table 6 isplaced upon or held by a supportc, pivoted at e to the main framework. The table-support e is formed with a recess for the table e, the top of the recess being provided with a tongue and the top of the inner end portion of the table being provided with a groove to receive said tongue, and a set-screw e is provided, which may be used to hold the table 6 fixed in any desired adjusted position, or the table 6 may be made movable in and out for a short distance, if

desired, in which case the set-screw 6 will 5 be loosened or omitted and a spring or (see dottedlines, Fig. 1) will be provided, hear ing against a pin n on the table-support e and againstthe table a, the action of which is to move the table out, and pins n pass up through webs or projections on the tablesupport and enter slots or grooves formed in the under side of the table, said slots or grooves being of such length as to limit the forward movement of the table, its rearward movement being limited by the inner end of the table bottoming in the recess. The table 6, thus yieldingly supported, may be moved in and out in order that the welt-beatin g hammer may act upon the welt more or less distant from the edge.

It is obvious that the table e may be made integral with the support 6; but by making it separate it may be adjusted in and out or caused to yield.

The pivoted table-support e rests upon or against a cam f, which serves as an abutment for it, and said cam f is pivoted to the frame atf. The cam f, which thus serves as an abutment for thetable, has its curved surface made of gradually-increasing radius from end to end, so that when the cam is in one position, as represented by dotted lines, Fig. 1, its point of shortest radius is in contact or engagement with the table-support, and consequently the table 6 is more or less removed from its normal elevated position, and when the cam f is moved into its opposite extreme position, as represented by full lines, Fig. 1, its point of longest radius is in contact or engagement with the table-support, and as a consequence the table 6 is held in its most elevated position. By holding the cam f at different intermediate points or positions the normal elevated position of the table a may be varied.

As a simple way of limiting the movement of the cam f in one directionrl. 6., in a direction to raise the table ean adjusting-screw 0 f passes through a projection f on the cam and is adapted to strike against a fixed point or stop f on the frame. The cam has attached to it a treadle rod or chain g, which may be connected with any suitable treadle for the purpose of depressing it or moving it in a direction to lift the table, and a strong spring g is attached at one end to the cam f and at the other end to the table-support, which acts to move the cam fin the opposite direction.

This construction of adjusting and operating device for adjusting and operating the table 6 may be changed in many ways without departing from the spirit and scope of the invention, but the particular construction shownviz., the cam fenables the table to be adjusted and held in different planes or elevations and also to be freely moved to facilitate admitting the work and also provides a good and efficient abutment to oppose or resist the force of the welt-beating hammer.

The table-support 6 has a tendency to turn on its pivot when its table 6 is receiving upon it the repeated blows of the hammer, and said support bears against the cam f continuously, the thrust being in a direction toward the pivots or bearings f of said cam, such direc tion of thrust continuing notwithstanding movements of the cam f to vary the position of the table.

The front end of the table is made as a stationary nose but it is obvious that a loose roll may be provided without departing from the spirit and scope of the invention.
