SIDE GAUGE PiN FOR PLATEN PRESSES Filed Oct. 8, 1930.
Inventor F235" Thomas Nels n,
A Home y Patented Mar. 15, 1932 THOMAS NELSON, OF JUNCTION CITY, OREGON SIDE GAUGE PIN FOR PLATEN PRESSES Application filed October 8, 1930. Serial No. 487,337.
This invention relates to certain new and useful improvements in'gauge pins, and has more particular reference to a type of gauge pin known in the art as a side gauge pin for use in conjunction with platen presses.
A primary object of this invention is to provide a gauge pin which may be stamped froma single blank of metal, and which may be used in conjunction with the grippers with which the press is usually equipped, whereby the grippers may be utilized for forcing the spring fingers of the pin into gripping engagement with the sheet to be printed.
A still further object of the invention is to provide a gauge pin of the character above mentioned, which is comparatively simple in construction, of greater strength and durability than pins heretofore used for this purpose, and which is otherwise fully adapted for the purpose designed.
Other objects and advantages of the invention will become apparent during a study of the following description, taken in connection with the accompanying drawings.
Figure l is a top plan view of the pin, the same being shown as applied in position on the press.
Figure 2 is a side edge elevational view Figure 3 is an end elevational View thereof.
Figure 4 is a longitudinal sectional view taken substantially on the line 4-4 of Figure 1.
Figure 5 is a top plan view of the pin per se.
lVith reference more in detail to the drawings, it will be seen that the pin, as comprehended by the present invention is formed from a single blank of metal including a body portion 1 that is slit longitudinally on two from the free ends of the spring fingers 3 is transversely of the body inwardly from the free ends of the fingers 3. lVhen in position,
the stop 4 isadapted to abut the adjacent edge of the sheet S.
Adjacent the upstanding stop 4, a portion of the material is bent downwardly in an opposite direction to the member 4 whereby to provide, adjacent opposite ends of the member 4, penetrating prongs 5 that are adapted to penetrate the usual tympan sheet'T.
The body 1 is also slit on two parallel longitudinally extending lines 6 extending inwardly of the body 1 remote from the stop 4 whereby to provide a relatively narrow elongated spring prong 7 that at its free end terminatesin a sharpened point 8 which projects beyond the corresponding end of the body 1.
hen the pin is in position on the press, the spring prong 7 is passed through the tympan sheet T in a manner clearly suggested inFigure 1 whereby the sharpened end 8 of the prong will rest flatly on the top face of saidv tympan sheet.
When the pin is secured on the tympan sheet, by reason of the spring prong 7 passed through the sheet, the sheet S upon which the matter is to be printed, may then be placed on the tympansheet T so that an edge portion of the sheet S will pass under the freeend portions of the spring fingers 8 whereby said edge of the sheet S will contact the stop 4.
The arrangement of parts thus being completed as suggested, the gripper with which the press is usually equipped, may then be brought into operation whereby to extend transversely of the pin so that the free ends of the spring fingers 3 will be urged into close contact with the sheet S and the penetrating points or prongs 5 pressed into the tympan' sheet T under the weight and pressure of the said gripper, (the gripper not being shown).
As is well known in the art, on platen presses there are two grippers which clasp the sheet being printed on either side of the sheet to hold it in position while the impression is being completed. With the usual gauge pins now on the market, it is impossible to use the left hand gripper if a side gauge pin is used. With the pin contemplated by the present invention, the gripper is set just to the left of the upright or projection or stop t and will firmly press the prongs 5 of the pin into the sheet and hold it more firmly than would be accomplished by the gripper itself. This permits of the use of the left hand gripper together with the gauge pin and also permits of the gauge pin serving the purposeof lower teed pins also used in conjunction with platen presses.
It is thoughtthat the construction, advantage and utility of an invention of this character will be had by those skilled in the art without a more detailed description.
Even though I have herein shown and described the preferred embodiment of my invention, it is to be understood that the same is susceptible to changes fully comprehended by the spirit of the invention as herein described, and the scope of the appended claims.
Having thus described my invention what- I wish to claim is:
l. A side gauge pin for platen presses comprising a relatively fiat body portion, a pair of spring fingers integral with said body and projecting beyond one end of said body adjacent opposite sides of said body, a stop integral with said body and extending at right angles thereto between said fingers, and a spring prong integral with said body and having its free end projecting beyond that end of said body remote from the free end of said fingers.
2. A side gauge pin for platen presses comprising a relatively fiat body portion, a pair of spring fingers integral with said body and projecting beyond one end of said body ad jacent opposite sides of said body, a stop integral with said body and extending at right angles thereto between said fingers, aspring prong integral with said body and having its free end projecting beyond that end of said body remote from the free end of said fingers, and penetrating prongs integral with said body adjacent said stop.
3. A side gauge pin for platen presses comprising a relatively flat body slit longitudinally adjacent opposite side edges thereof whereby to provide a pair of spring fingers the free ends of which are adapted to overlie and engage the sheet to be printed upon, said body inwardly from the ends of said fingers being bent on a transverse line to provide an upstanding projection constituting a stop for engagement with the adjacent edge of said sheet, said body being further slit longitudinally whereby to provide an integral prong bendable relative to said body, said prong having one end thereof projecting beyond that end of said body remote from said stop, and adapted to be passed through the tympan sheetof the press.
l. A side gauge pin for platen presses comprising a relatively flat body slit longitudinally adjacent opposite side edges thereof whereby to provide a pair of spring fingers the free ends of which are adapted to overlie and engage the sheet to beprinted upon, said body inwardly from the ends of said fingers being bent on a transverse line to provide an upstanding projection constituting a stop for engagement with the adjacent edge of said sheet, said body being further slit longitudinally whereby to provide an integral prong bendable relative to said body, said prong having one end thereof projecting beyond that end of said body remote from said stop and adapted to be passed through the tympan sheet of the press, and said body at said transverse line of bend adjacent opposite ends of said stop being bent in a direction opposite to said stop whereby to provide a pair of penetrating points adapted to be forced into said tympan sheet under pressure of the gripper member of the platen press.
In testimony whereof I afiix my signature.
THOMAS NELSON.
