LEATHER-GLASSING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 672,903, dated April 30, 1901.

Application filed December 8, 1900. Serial No. 38,386. (No'modeh) The objects of the present invention in-' clude improvements in various features of construction and arrangement whereby an apparatus is produced which has proved in practice to be better able to withstand the severe strains of constant use and on account of its superiority of structure producing much less.

noise than usual and being at once more durable and economical in operation, as will appear from the following description and the accompanying drawings, in which Figure 1 is a vertical side elevation. 2 is an end View thereof.

In the drawings, A is a strong wooden beam constituting the base or sill. of the base a are strongly secured two uprights B O, which extend upward therefrom in par- Fig.

allel forwardly-inclined positions and are se-- cured at their upper ends to opposite sides of the front end of whatI have termed the headboard D. Near the forward end of the base A are secured a second pair of uprights E F, which are similarly secured on opposite sides of the rear end of the head-board D. The two sets of uprights intersect, forming an exceedingly strong and rigid X-frame sustained upon the base A and supporting the head-board D. The said uprights B (J EB are desirably secured together at the points of intersection, and it is furthermore pointed out that the frame is not quite symmetrical, since the feet of the forward uprights E F are set some dis tance back of the front end of the sill A,

which carries the work-bed, while the upward ends of the opposite set of uprights extend At the rear end forward and connect with the forward end of the head-board D'at a point beyond the support"of the working tool, which travels over the bed, as will appear, the object being to afford sufficient space for the work-bed and tool and to efficientl'y support the tool-carrying mechanism suspended from the front end of, the said head-board D.

At the forward end of the sill A is located the work-bed G. This bed is constructed in the usual well-known manner and is suspended upon a wooden spring 6, the opposite ends of which are supported upon adj ustingscrews ff, which are sustained in the baseblocks 0 0 mounted upon the forward portion of the base A. Upon and over the bed G moves the glassing-tool g, which is reciprocated back and forth upon the surface of the leather placed upon the bed G. The glassingetool g is supported by the rocker H, connected therewith through a vertical member h, extending downward from the middle of the rocker, said member It being strengthened by front and rear diagonal braces h M, extending from the under side of opposite ends of the rocker H and secured to the vertical connecting-bar h. The rocker is adapted to be held up against and move upon a rockertread I,which is removably secured to the under side. of the head-board D, so that it may be readily renewed when worn. The head-board D is stationary, being secured between the upper portions of the four uprights. Above the rear portion of the headboard D is secured a spring-board d, which is most conveniently pivoted upon a bolt J, between the upward extensions E F of. the upright braces E F, although separate supports upon the rear end of the head-board D would answer the same purpose. The springboard (1 extends parallel with the-head-board D to a point beyond the vertical support of the rocker H, with which it is connected by bars or straps K L, which are connected above the spring-board by bolt is and extend down and through suitable slots or openings (not shown) in the head-board D to and are pivotally connected with the center of the rocker H by a through-bolt M. This connection sustains the rocker vertically and the spring-board d will yield to permit movement of the rocker. Springs, preferably coil-springs 70 Z, are intel-posed between the under side of the springboard d and the upper side of the head-board D, said springs being of a tension designed to carry the weight of the rocker and attached parts without unduly impeding their movement. In order to keep the rocker in position and prevent longitudinal movement thereof as a whole, the longitudinal stays O P are provided in the form of narrow bars of metal, which are pivoted at their forward ends upon the bolt Mthat is, upon the same axis as the vertical supports K L-and are similarly secured at their rear ends by a bolt on passing through a block m, secured under the rear end of the head-board, or by a bolt passing through the rear uprights E F, so that said stays have suificient length to permit cramping, are parallel and horizontal, and cooperate with the vertical straps K L. This is a valuable feature of improvement, as the tendency of the rocker to creep along its tread is continuous and powerful and is effectually prevented by means of this construction, which is simple and eEective.

The tool 9 is carried in a suitable head N, which is pivotally secured at the lower end of the vertical bar 71, depending from the rocker. The head N is joined to the drivingwheel Q by connecting-rod n, which at its rear is journaled upon a crank-pin q. The driving-wheel Q is sustained upon shaft R, which is mounted in asuitable journal secured to the cross-pieces at one side of the machine and extending laterally therefrom to a suitable rigid support S, mounted upon separate base a, and the said shaft is provided with the usual fast and loose pulleys r s.

In order to readily compensate for wear on the surface of the rocker against its tread I, the latter is removably attached to the under side of the head-board and may be made of a strip of the most suitable wood for the purpose and may be dilferent in that respect from the head-board.

Having specifically described my improved machine and the construction and arrangement thereof, it will be apparent that minor changes and modifications may be made by any one skilled in the art without the exercise of invention.

Having described my invention, what I claim is 1. In a glassing-machine, the combination with the base, work-bed on forward end thereof, a head-board extending over the base and bed, and supporting a rocker near its front end and over the work-bed, two sets of inclined uprights, the rear end of one set exrear of the work-bed and to the rear end of the headboard.

2. In a glassing-machine, the combination with the base, work-bed on forward end thereof, a head-board extending over the base and bed and supporting a rocker near its front end and over the work-bed, two sets of inclined uprights, the rear end of one set extending from the rear of the base tothe front end of the head-board beyond the center of movement of the rocker and vertically over the bed, the other set extending from the base at the rear of the Work-bed and to the rear end of the head-board.

3. In a glassing-machine,'the combination with the base, work-bed, sustaining-frame, and the rigidly-supported head-board, of a spring-board spring sustained above the headboard, a rocker suspended below the headboard, and vertical and lateral stays therefor, having their downward ends united upon the axis upon which the rocker is suspended.

4. In a glassing-machine, the combination with a base, a work-bed on the front end thereof, a head-board extending over said workbed, cross-pieces connecting same, a rocker depending from the head-board, a springboard over the work-bed, springs between the board and the bed, a pair of suspensionstraps connected to the spring and .pivotally connected to the rocker below the head-board, and a pair of longitudinal stays arranged one on each side of the rocker and pivotally connected thereto on the same axis as the supporting-straps and suitably secured at their rear ends.

5. In a glassing-machine, the combination with a base, work-bed, head-board extending over the bed, a pair of inclined uprights secured to and extending from the rear end of the base to and secured to the front end of the head-board, a second pair of uprights secured to the base near the rear of the workbed and extending up to and secured to the rear end of the work-bed and having extensions, a spring-board pivoted at its rear end to the extensions of the uprights, a rockerframe and polishing mechanism, springs between the pivoted spring-board and a stationary head-board, a pair of straps extending from the spring-board downwardly and pivotally attached to the rocker for suspending thesame and a pair of longitudinal stays pivoted upon theaxis of the vertical straps and extending rearward to and secured to a part connected to the rear end of the head-board.

6. In a glassing-machine, the combination with the base, the work-bed on the forward end thereof, of a head-board suspended so as to extend over the work-bed, a rocker-frame, glassing-tool, and driving connections ar ranged between the front end of the headboard and the work-bed, two sets of inclined uprights, the rear end of one set secured to and extending from the rear of the base and secured to the front end of the head-board, said uprights arranged one on each side of the rocker and attached mechanism, the other set secured to the base near the rear of the work-bed and extending up to and secured to the rear of the head-board, the two sets of uprights intersecting and forming an open framework within which the operating mechanism is free to move.
