FEED-GAGE FOR PRlNTlNG-PRESSES.
SPECIFICATION forming part of Letters Patent No. 571,782, dated November 24:, 1896.
Application filed February 10,1896. erm-1N0. 578,728. (No model.)
To (0M whom, it 72mg con-corn:
Be it known that I, EDWARD L. MEGILL, a citizen of the United States, residing at Brooklyn, Kings countygllew York, have invented certain new and useful Improvements in Feed-Gages for Printing-Presses, of which the following is a specification.
This invention relates to a feed-gage for application to the platen of a printing press or machine, and more particularly to the class known as pin-gages.
One feature of the invention is the device whereby the pin is clamped to the paper to prevent it from slippingafter the adjustment shall have been effected, and another feature relates to the construction. whereby the gagehead is secured to the pin. The construction permits the use of sheet metal for the gage-head and round wire for the pin.
The accompanying drawings illustrate several embodiments of the invention.
In the drawings, Figure 1 is a plan of the gage. Fig. 2 is arear elevation thereof. Fig. 3 is a longitudinal vertical axial section thereof. Fig. i is a plan showing the gage set in the platen-sheet. Fig. 5 is a view of the sheet-metal blank from which the gage is constructed. Fig. 6 is a plan view of the gage without the looking or binding dog. Fig. 7 is a plan, and Fig. 8 a longitudinal vertical section, of a gage with a flat pin provided with my improvements. Fig. 9 is a View of the pin-wire. These views are drawn toa somewhat exaggerated scale in order to better illustrate the construction.
The gage as illustrated in the first four figures of the drawings comprises a broad head 1, two lateral supports 2 2, extending back from the head, a pin 3, of round wire, secured at its front end to the head and situated between the supports 2, a strippingfinger i, secured to the head and projecting therefrom in the usual way, and a looking or binding dog 5, which is pirotally mounted on the gage and adapted to swing horizontally about its pivot.
erture 1, leaving alittle space, however, between the two plies. The supports 2 are now formed by bending back the ends of the blank, these supports being brought in the bending rather near together, as shown in the plan.
The pin 3 is now formed by pointing the end of a piece of round wire and flattening a portion thereof, as indicated at 8 in Fig. 9.
The sheet-metal blank is first bent up to shape and the flattened portion of the pinwire is then passed up between the two plies of the gage-head and through the aperture 1', and two bends are made in the wire, one to place the pin substantially at right angles to the face of the gage-head and the other to place the stripping-finger 4 in alike position, but projecting forward. The wing or plate 1 may now be pressed up more closely to the head, so as to cause it to bind the flattened portion of the pin-wire the more closely. The object of this construction may be here explained. It is desirable to employ a slender pin of round wire on a gage of this character, as such a pin cuts the platen-paper less than a flat pin, and thus permits the pin to be inserted quite close to a hole already made in the paper, so as to effect a close ad j ustmcnt; but it has been found difficult to secure a round wire pin to a suitable sheet-metal gagepin. It maybe secured by solder, but this mode of fastening is found to be-Yery insecure, as the pin so secured will break away under a very slight strain. The means of fastening illustrated and described herein provide a construction substantially as strong as though the parts were in one piece or integral.
It is desirable for purposes of adjustment that after the pin is inserted and the gage set and properly adjusted the platen-paper (a; in Fig. 4) over the pin shall be clamped down forcibly on the top of the pin, and this is effected by means of the locking or binding dog 5, before mentioned. On the blank seen in Fig. 5 will be observed an apertured projection 1'. Then the blank is bent to shape, this projecting part is bent so as to bridge over the space between the supports 2 and rest thereon and to form a bearing to which will be pivotally attached the dog 5. This dog will be of sheet metal bent down at seen 1n 131g. at the edge of the same which its free end, as seen in Fig. 3 and rounded at s corners, as seen in Fig. 2. The spring of the parts is such that when the pin is inserted and the dog 5 turned to the position rests on the paper presses the paper down forcibly on the pin 3 and clamps it to the pin.
Figs. 7 and 8 illustrate a gage having a flat pin formed integrally with the flap or ply 1 of the head and extending rearwardly from the lower edge of the same. The lip 1, to which the dog- 5 is pivotally connected, is also formed integrally from the plate or sheet in forming the aperture 1. The stripperfinger 4 is not in this construction integral with the pin It will be noted that the pivot-ingstud of the dog 5 is substantially perpendicular to the base of the gage, and that the pendent operative edge of the dog is rounded at one or both corners, so that the said edge may be made to ride over the pin readily by a lateral movement of the dog about its pivot.
As herein shown, the lip l is represented as taking over the hinging-lug on the dog, but it is not material which piece is underneath.
By bending the blank to form the rearwardly-extending supports 2 and bringing these latter in quite close to the pin the supports are placed edgewise to the paper, so as to be stiff and bind the paper over the pin, and the breadth is at the same time given to the gage-head.
IIavin g thus described my invention, -I claim 1. A pin feed-gage having a dog 5, pivoted to the gage and adapted to swing laterally over the pin at the rear of the gage and press the overlying platen-paper down tightly thereon, substantially as set forth. I
2. A pin feed-gage having lateral supports 2,2,e'xtending rearwardly from the gage-head, a bridge-piece 1 on said supports, and a dog 5, pivoted at its front end to said bridgepiece and its free end adapted to take over the rearwardly-proj ectin pin of the gage and press the platen-paper down forcibly thereon,
substantially as set forth.
. 3. In a feed-gage having a gage-head and rearWardly-projecting pin to pierce the platen-paper, the combination of the said head provided with means for pivotally connecting the dog thereto, and the said pin, of the said dog, 5, pivoted on an upright stud and adapted to swinglaterally, said dog having at its free end a lip adapted to bear on the platen-paper and press the latter down upon the inserted pin, substantially as set forth.
4. A pin feed-gage having a sheet-metal gage-head 1, with an integral folded flap 1 and an aperture 1 at the fold of the flap, and having a round pin, 3, with a flattened portion, said flattened portion being bent upwardly and embraced between the plies of the head and extending through said aperture 1, substantially as set forth.
5. A pin feed-gage having a sheetmetal gage-head formed of two plies, as described, and having a pin 3 and stripping-finger 4, formed integrally, a portion between said pin and finger being tightly embraced between the plies of the gage-head, substantially as set forth.
6. A feed-gage comprising a head formed of two integral plies of sheet metal and having lateral supports integral with the head and extending rearwardly therefrom, and a round wire pin having a portion flattened and tightly embraced between the plies of the gage-head, said pin being bent substantially at right angles to the face of the gagehead and extending rearwardly therefrom between said supports, substantially as set forth.
In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
EDlVARD L. MEGILL.
