CASPER L. REDFIELD, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE CHICAGO MATRIX MACHINE COMPANY.
TYPE-DIE HOLDER FOR MATRIX-MAKING MACHINES.
SPECIFICATION forming part of Letters Patent No. 428,138, dated May 20, 1890.
Application filed March 25, 1889. Serial No. 304,676. (No model.)
To aZZ whom. it may concern.-
Be it knownthat I, CASPER L. REDFIELD, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Type-Die Holders for Matrix-Making Machines, of which the following is a specification.
My invention relates to the class of machines in which an oscillating sliding lever is used for carrying type-dies and presenting them successively to an impression device to be pressed into a matrix-body.
The object of the invention is to lessen the weightrequired to be carried by the lever, and to provide suitable holders for the dies and means for readily removing them from their holders; and, generally stated, the invention consists in bushings in the holes in the lever in which the dies are supported and slide, and in which they are locked by means of slots and studs.
My improvements are illustrated in the accompanying drawings, in which- Figure 1 is a side view, partly sectional, of the lever, its guide, and the die-holders. Fig. 2 is a plan View of the same. Figs. 3 and 4 are details of the holders and dies. 5 is a vertical section of Fig. 3 on the line 00 0c, and Figs. 6 and 7 show slightly-modified constructions of the same.
In said drawings, 1 designates a portion of themachine-frame; 2,aguide; 3,across-head therein, on which the lever is pivoted; 4, the oscillating sliding lever fulcrumed to the cross-head by a pivot-pin 5.
In suitably-arranged holes in the widened end of the lever are bushings 6, having flanges 7 at the under side, by means of which they may be brazed or otherwise fastened to the under side of the lever. In these bushings are guided the type-dies 8,Which are supported by spiral springs 9, having their lower portions around the bushings and resting on the face of the lever and their upper ends attached to the upper portions of the dies. In the bushings are slots 11, in which keys 10 on the dies lit. The dies are thus guided and permitted vertical movement in the bushings, and any lateral turningis prevented. To remove the dies, it is only necessary to free the upper end of the springs, when the dies may be made to slide out downward, the keys 10 passing out of the slots 11.
In the modified construction shown in Figs. 5 and 6 a shoulder 12 is provided on the upper end of the die, against which the spring (the upper portion of which only is shown in the drawings) presses, the lower end resting on the lever and a bayonet-joint is made by means of an angular slot 13 in the bushing, into which is passed the stud 14, carried by the die. By these means the double frame is dispensed with and the weight to be carried by the lever is much lessened, while the dies are still properly guided and are rendered easily removable.
I make no claim herein other than to the die-holding devices, the die-carrying lever itself being the subject-matter of an application for patent filed by me on the 20th day of February, 1889, and seriallynumbered 300,536.
Having described my invention, what I claim, and desire to secure by Letters Patent, 1s
1. In combination with the perforated supporting and carrying plate, a tubular guide provided with a flange, said guide being projected through the opening in the plate with its flange abutting the face thereof, and the typedie fitted to reciprocate in said tubular guide and provided with a spline engaging the walls of a slot, substantially as set forth.
2. The combination, with the perforated plate, of a flanged socket inserted through said plate and secured thereto, a type-die fitted to reciprocate in said socket, and a retracting-spring engaging the upper end of the type-die, substantially as set forth.
CASPER L. REDFIELD. Witnesses:
