MACHINE FOR PERFORATING STRIPS FOR. SINGLE-TYPE-CASTING MACHINES.

Specification of Iietters Patent.

Application filed June 3D, 1915. Serial No. 37,404.

To all whom it may concern.

Be it known that I, Gnono AMRHEIN, citizen of Germany, residing at Munich, Bavaria, Germany, have invented certain new and useful Improvements in Machines for Perforating Strips for Single-Type- Casting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap-pertains to make and use the same.

The present invention relates to the manufacture of perforated strips for single-typecasting machines.

The present invention consists of a device for manufacturing such perforated strips and is mainly characterized by the fact that the marginal perforations are made by means of the pin wheels of the feed mechanism, advancing the paper strips and in one operation with the keys. For this purpose the unperforated paper strip is guided over a loosely revolving roller, which presses the paper strip against the teeth of the said pin wheels.

In order to render the present invention more easily intelligible reference is had to the accompanying drawings.

Figure 1 shows diagrammatically partly in section and partly in side view an apparatus, according to this present invention, while Fig. 2 is a section on line AB of Fig. 1.

Referring to the drawing a. is the standard carrying the apparatus. 12 is a supply roll and d an unperforated paper strip, wound off the said supply roll I) and e is a winding spool, upon which the paper strip cl is wound again after it is perforated. f are jaws, attached to the sides of the standard a and g are the pinwheels of the feed mechanism, said pin wheels being loosely rotatable and mounted on either of the said jaws f, and advancing with their teeth the paper strip as soon as it is perforated. Between the pin wheels 9 there is provided a die cylinder h, which is stationary and open at the top. This die cylinder 72. serves for the letter perforation and receives the waste material from the paper strip being pushed through by the punch 11. In front of the pin wheels 9 a sleeve 70 is loosely located, which in the path of the pin wheels 9 is provided with circumferential apertures 1, in which the teeth of the pin wheels engage in such a manner that the said pin wheelsg and the sleeve .70 form, so to say, a gear, between Patented Nov. 2, 1915.

which the unperforated paper strip (Z, which extends over the width of the sleeve, is

ipassed. The sleeve is is loosely rotatable aroundan axle m, which is providedat its two ends with collars n, which in the path of the apertures 1 contain each acircular groove 0, which is so deep that no resistance is offered to the pin wheels g. The collars 12 may be arranged more toward the middle so that};1 then the grooves 0 may be dispensed wit The sleeve is and its bearing are preferably detachable and the sleeve 70 may be spring pressed so that it may be yieldingly forced against the pin wheels. For this purpose the axle m is journaled in two plates 79 arranged sidewise of the jaws 7, preferably in rearwardly open slots 7". The plates 12 are loosely suspended on a cross bar 8, so

that when the plates 79 are turned forward. the sleeve is is moved away from the pin wheels 9 and maybe removed. t are adjustable springs, which act against the plates 79 and the other end of which is attached to the standard a, so that the suspended parts 79, is may be pressed against the pin wheels.

In front of the sleeve 70 there is preferably provided a guiding roller a, which is positioned in the plates 79 and by means of slantingly upwardly directed slots o, is rendered capable of rotation and of being lifted.

The unperforated strip (Z, being wound off the roller 1) is passed over the under side of the roller to, over the upper side of the sleeve k, between the latter and the pin wheels 9 and finally to the winding spool e. As soon as the feeler apparatus is set into operation the teeth of the pin wheels 9, engaging the aperture 1 of the sleeve 70, are forced into the unperforated paper strip and impress the two rows of holes, which are situated near the edges of the paper strip. Those teeth of the pin wheels, which are in front of the teeth effecting the perforation, at once enter the holes to and advance thanbefore, And-"thisfor the reasonthat the teeth of the pin wheels 9 do not cut holes, allowing more or less play, but such holes, which exactly correspond to the form of the teeth, and. which fit exactly the teeth of the ratchet-wheels. of the casting machine.

Should any jerking advancing movement occur when winding off the paper strip, or should the latter be stopped or hemmed this will be compensated by the yieldingly posithe paper strip (Z, (Z is always somewhat lifted, falls down again in the slots 2; and

."thus draws the paper strip from the sup- 20' plyroll 7).

Paper waste and the like may be removed from the circular grooves 0 by raising the 'sleeve'ic away from the pin wheels 9- and then brushing such waste into the interior,

m, of the sleeve is or into a separate receptacle, as desired.

I claim as my 1nvent1on:

-1. In apparatus for the purpose set forth,

the combination of a supply roll adapted to support areel of imperforated material, we. winding spool adapted toreceive'said material'after perforation thereof, pin wheels arranged between said roll and said spool,

and a sleeve adjacent to said pin Wheels, said sleeve havlng perforations into which the teeth of said pin wheels enter, whereby said pin wheels are adapted to simultaneously feed said material and perforate the "advanceof said sleeve; 1 e In testimony whereof I hereunto affix my Vitnesses "same in its passages-0m? the fksupply roll to the winding spool.
