FRITZ MKURER, OF N'UREMBERG, GERMANY.

MACHINE FOR THE PRODUCTION OF STEREOTYPE-MATRIGES.

Patented Feb. 2, 1909.

Serial No. 355,038.

To all whom it may concern:

Be it known that I, FRITZ MAURER, whose ()SlJ-OfllOB address is No. 29 Ostendstrasse,

uremberg, Bavaria, in the Empire of Germany, have invented certain new and useful Improvements in Machines for the Production of Stereotype-Matrices; and I do hereby declare the followin to be a full, clear, and exact description 0 the invention, such as will enable others skilled in the art to which it a pertains to make and use the same.

T is invention relates to a machine for producing stereotype matrices in which the repared pa er is eaten into the type or die by means 0 a brush. In the mac ine the brush is given a vertical reciprocating movement by mechanical means and is ressed into the paper which is to be molde The annexed drawings illustrate forms of construction of the machine in which Figure 1 is a side elevatiofr of a second form of construction, Fig. 2 is a plan of the same part being omitted, Figs. 3 and 4 show on a lar or sea e individual parts of the machine 0 Figs. 1 and 2, Fig. 5 illustrates in cross-section a special form of raisin -crank pin of the machine of Fi s. 1 and 2, ig. 6 is a longitudinal section -0 the crank pin.

The form of construction of the machine shown in Fi s. 1 to 4 is on the same principle as describef, the brush being given a reciprocatin movement by mechanical means.

The eatures of the construction are as follows: The brush 1 is as before described fixed on a slide piece 2, which has reciprocating movement in a guide 3 of the arm 4 of the 'frame. The slide piece 2 is at its up er end provided with a frlction pulley 20 an is raised by an eccentric 21 which is rotated by a shaft 22. The brush 1 with the slide iece 2 is held downwards by a spring 23, which is attached at the one end to the guide 3 and at the other end to the slide iece 2, so that the brush is drawn towards t e matrix. Above the slide piece 2 is arranged a cylinder 24, in which a piston 25 moves, said piston is connected to the slide piece 2 by a rod 26. The cylinder 24 is open at its u per end and is rovided with a cock 27, y means of whlch the resistance of the air cushion in the cylinder, caused by the downward movement of brush and iston 25, can be re ulated. In the bed 0 the cylinder 24 an in ct valve 28 is provided which allows the air to be sucked in on the rising of piston. The air cushion in the cylinder 24 governed by the cock 27 allows the regulation of the stroke of the brush and also contributes to the resiliency of the stroke of the brush on the matrix.

On the main shaft 22 is seated a pulley wheel 29, which is connected to the shaft by a pin-coupling. By depressing the pedal lever 30 the rod 31 draws the pin 32 out of the cou ling and the shaft 22 is rotated by the pulley wheel 29 driven by means of a belt or the like so that the machine is set in action.

On the shaft 22 is wedged a crank disk 33, to which the crank rod 34 is displaceably fixed. The lower end of the rod 34 is connected to the axle 35 by a rotatable lever 36, which bears on the arm of a wheel 37. The wheel 37 is fixedly connected with a toothed wheel 39, which engages with a toothed wheel 41 loosely seated on a shaft 40.

The sliding rest for the matrix consists of a base late 42 movable in the longitudinal direction and a table 43 movable transversely thereto. For actuating the same the two plates 42 and 43 are provided each with a toothed rod 44 and 45, with which toothed wheels 46 and 47 engage. The toothed wheel 47 is seated non-rotatably on shaft 35 but is slidable thereon with the under table 42 and causes the transverse movement of the table 43. The toothed wheel 46 is rotated by means of beveled wheel gear 48 of the shaft 40 and operates the movement of both tables 42 and 43 in the longitudinal direction.

In order that the two shafts 35 and 40 can turn in both directions, couplings 49 and 50 are arranged, which can be engaged to the left or to the right with conical toothed wheels loosely seated on shaft 35. The engaging and disengaging of the couplings 49 and 50 is done by pivoted levers 51 and 52 which are connected by means of o crating rods 53 and 54 with the levers 55 an 56.

The work table is only moved during the upward movement of the brush.

In order to obtain elasticity in the stroke of the brush, the's ring 23 can be replaced by an air cushion i5. 4). The cylinder 24,

reviously describe as open at its u er end, is closed in this case and provided wit an inlet valve 57. By the upward movement of the piston 25 the air is compressed in the chamber 58 of the c linder so that after the release of the brush y the eccentric, the piston is moved downwards by the compressed air. The lower part of the cylinder allows also in this form of constructoin of regulating l the toothed rod 67 is drawn out by means of the force of the stroke.

Figs. 5 and 6 show a form of construction of the eccentric for raising the brush, in the machine shown in Figs. 1 to 4, and is for the purpose of allowing the stroke of the brush to be regulated by lengthening or shortening the eccentric.

The eccentric 21 of the shaft 22 is provided with a removable foot 59 in which are seated the screw-threaded ends 60 and 61 of guide pins 62 and 63. The pins slide in correspondmg bores of the eccentric 21. The in 63 is formed as a toothed rod, the teet 64 of which engage with a toothed wheel 65, carried by a spindle 66 mounted in the interior of the eccentric 21, the wheel also engages with a toothed rod 67 rectangularl arranged to the pin 63. Therod 67 can sli e in a passage parallel to the axisof the shaft 22 and is rovided at its outer end with a bent part 68 1n which is seated and connected by means of a screw 70 a button 69. The screw 70 engages for instance in an annular groove 71 of the button so that the same is free to turn. The bent portion 68 has the pur ose of keeping the button 69 on the axis 0 the shaft 22 of said button for facilitating the operation during the action of the machine.

At the position of the parts as illustrated in the drawlng, the inside of the foot 59 bears against the corresponding side of the part of the eccentric 21 and the stroke produced is the shortest. If the stroke is to be increased the button 69. By this means the wheel 65 is turned, and the pin 63 is moved. downwards so that the foot 59 is removed from the part 21, and the length of stroke is consequently increased.

It is evident that the alternation of the length of stroke can be done during the rev-.

would serve for operating the rotation of the same.

What I claim and desire to secure by Letters Patent is:

A matrix making machine comprising in combination, a support for the matrix, a reciprocating brush cooperating with said matrix, a sprmg effecting working reciprocation of said brush when released, a dashot acting in opposition to said means for imiting the speed of the working stroke of said brush, and a cam acting in opposition to said means for returning said brush to a starting position and releasing said brush at such position.

In testimony whereof I EtffiX my slgnature in presence of two witnesses.

FRITZ MAURER.
