JOSEPH W. HEJDA, OF VIRGINIA, MINNESOTA.
DEVICE FOR FREEING- POINTS OF A PERFORATING- RULE FROM PAPER OR ANY MATERIAL BEING PERFORATED.
Application filed May 14, 1920. Serial No. 381,458.
To all whom it may concern:
Be it known that I, Josnrn W. HEJDA, a citizen of the United States, residing at Virginia, in the county of St. Louis and State of Minnesota, have invented a new and useful Device for Freeing Points of a Perforating Rule from Paper or Any Material Being Perforated, of which the following is a specification.
This invention relates to a device which looks in any ordinary printers chase, together with an ordinary perforating rule making it possible to run jobs of perforating on standard job platen presses as rapidly and as conveniently as an ordinary job of printing.
It positively frees the paper or material being perforated, from the points of the per forating rule without the use of grippers, rubber bands, strings, brass rule bent around gripper, gripper fingers, etc. It saves time of operator in make ready on press and leaves the material which is being perforated smooth and unwrinkled. The device is simple, substantial, compact, non-encumbering and inexpensive in construction, as well as being convenient, serviceable, and practical in use.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.
The device may be made of metal or other suitable material. Flat springs might be used instead of coiled springs. The invention canbe made in units of any convenient size, but I prefer to make them in lengths according to printers scale like 15 ems, 10 ems, 5 ems, etc, and a convenient width is 3 ems, which is equal to inch. Thus the units will easily fit in the chase and lock together with printers standard furniture.
The invention is illustrated in the accompanying drawing, wherein:
Figure 1 is a plan view of the device.
Figure 2 is a side view of the device.
Figure 3 is an end View of the device.
Figure t is a plan view of an ordinary printers chase showing a number of units of the invention locked in along side of a number of ordinary perforating rules all set up ready for operation in a platen press.
Figure 5 is a cross section of the chase along line AA showing the position of the top bar of the invention in relation to the teeth of a perforating rule.
Similar numbers in the different views refer to the same parts.
The device consists of a base 1, with a counter bore 2 near each end which contains the spring 3, said spring fastened to base by means of a small pin 4: passing through it. The top bar 5 is slightly smaller than the base so as not to interfere with the tops of other units placed along side of it and also to prevent same'from rubbing against the perforating rule when in operation. The top part also contains a shallow counter bore 6 near each end into which one end of the spring fastens by soldering or it may also be fastened by means of a pin passing through it.
In Figures 1- and 5, numbers 7, 8, 9, and 10 represent ordinary perforating rules with units of this invention ll, 12, 13, 14, 15, 16, placed along side of said erforating rules and all looked together in t e printers chase 17 by means of ordinary printers furniture 18.
In practice the top bar of the invention projects a little above the teeth of perforating rule, when in an idle position and when in operation the springs compress, forcing the top bar of the device below the teeth of the perforating rule just as the teeth enter the paper or stock to be perforated and upon retracting, the top comes up again releasing the paper or stock from the points of the perforating rule and leaving the said paper or stock flat and unwrinkled.
Having thus described the invention, What for holding the springs in place, said bars 10 I claim as new is zadapted to be placed on each side of the rule A perforated attachment for printing in such a manner that When the pressure of presses, in combination with an ordinary the press is applied, the compressing of the 5 perforated rule, a device comprising a base, device permits the perforated rule to pera top. bar, each having aligned counterbores, forate the paper, and immediately on releas- 15 springs interposed between the two and exing the pressure push the paper from the erting pressure outwardly, pins running perforated rule. transversely of the counterbore of the base JOSEPH W. HEJDA.
