FEED GAUGE FOR PRINTING PRESSES Filed Dec. 28, 1936 v Eu eve. Pa 176" F1 10 Fly. 8 9 I VENTOR BYMM Womiw .9 9 ATTORNEY Patented Dec. 21, 1937 UNITED STATE 2,102,910 FEED GAUGE FOR PRINTING PRESS ES Eugene Payne, Chattanooga, Tenn. Application December 28, 1936, Serial No. 117,731

6 Claims.

My invention relates to gauges and more particularly to gauges for positioning the stock on printing presses.

It has been the practice in the prior art of what 5 is known as job printing which consists of printing circulars, letter heads, labels, and forms of various kinds to use what is commonly called a job press having a draw sheet of appropriate thickness upon which is mounted gauges for positioning and carrying the stock to be printed into and out of engagement with the type form.

In the prior art considerable diiiiculty has been encountered with these gauges. A consideration of some of the various forms of gauges will serve to illustrate the problems solved by applicant.

In the general form of the present feed gauge a prong or blade is locked to, by piercing, the draw sheet or tympan sheet. "This blade is secured at one end thereof to a head which has legs or wings integral therewith and extending 'rearwardly thereof. and which rest on the face of the draw sheet. A pin or tongue is adjustably secured to the wings and extends through a slot in the head. Teeth for seating in the draw sheet are secured to the head and are intended to position it along such sheet to accommodate changing sizes of stock.

It is necessary to employ wax for sealing the pinto the draw sheet, and as inadequate means isernployed for anchoring, there is always the chance of accidental displacement by striking, and even where light stock is fed to the press it is also necessary to employ wax for precision work. For close register work it is necessary to move the pin down in the slot in the head towards 'the draw sheet, and insert a sharpened wooden wedge to maintain it in position. This is very inconvenient, requires a great deal of delay and provides no satisfactory holding means. And finally the use of sealing wax. retards or prevents adjustment of the tongue along the legs or wings over which it must travel.

.Applicant with a knowledge of all of these objections to and defects in the prior art has for an object of his invention provided a. gauge having a body portion including the conventional head and a wedge shaped tail, a prong or blade secured to that head and rows of onset teeth formed on the tail resulting in a large moment arm between the points of contact of theiteeth with the draw sheet and giving a maximum resisting effect against rotation caused by engagement with stock and other objects and eliminating the necessity for the use of wax which prevents further adjustment as w unclean material.

Applicant has as a isten 5 PATENT OFFICE ell as introducessticky and further object the provision of a number of anchoring teeth which will resist to a maximum degree any tendency for relative movement.

Applicanthas'for a of three sets of teeth employed to anchor the further object the provision which may be successively gauge to the draw sheet,

permitting of slight adjustment without producing large holes in anchoring effect.

Applicant has as the sheet which destroy the a still further object of his invention the provision of a gauge having aslotted body portion cooperating with portions of an adjustable pin or tongue permitting its movement with respect thereto ment and locking such tongue or but resisting such movepin so that it may not be separated from the body portion except at one position,

therebygiving an adjustable tongue which will retain its position when being so adjusted.

Applicant has as a s vention the provision a plurality of openings in receiving the pin or tongue it for close gauge or till further object of his'inof a feed gauge employing the head for successively to positively position otherwise and eliminating the necessity for use of sharpened wooden wedges for this purpose.

Other objects and advantages of my invention will appear in the the novel features of ticularly pointed out in following specification, and

my invention will be parthe annexed claims.

Figure 5 is a modification oi the same Figure 6 is an end view side elevation of gauge from the bottom. of the head of my gauge.

Figure '7 is a cross-section of a detail of my pin securing means.

Figure 8 is plan view of my pin.

Figure 9 is a side elevation of my improved pin. Figure 10 is an end view of the same pin.

Referring to the drawing in detail, It] designates a resilient pin or with H which cooperates tongue carried by a body projections l5, l5 overlapping the outer surface of the body and an arched central portion slot H to interlock the body walls defining the 23 which under hangs the and pin together as in Figure '7. Adjacent one end of slot H is an enlarged portion l4 permitting the disengagement body portion. Projections l2,

serve to guide the sto of the pin from the i2 on the head ck into position.

Secured to the head is a prong or blade I6 and on the paper engaging portion are teeth I I, I I. The tail or rear portion of the body is formed in wedge shape having sets of anchoring teeth on'the draw sheet engaging'face. The first set of teeth I8, I8 are most widely spaced and form the most extreme points on the wedge. The next set to the rearwardly are IS, IS which are offset from the first set and spaced more closely together. The last set is located-at the extreme rear and are on the point of the wedge, being oiT-set longitudinally and laterally from the other sets, are most closely related and are designated by 20, 20.

In the modification of Figure 5 a double blade or prong 25, 26 is employed to secure the gauge to the draw sheet.

In the head is formed a plurality of slots 2|, 22

through which the tongue I 0 may be successively extended. For other than close gauge Work the tongue ordinarily extends through slot 22. In this way the necessity for a wooden or other wedge inserted behind the tongue to force it down into close gauge position is entirely eliminated, and the tongue is always positively positioned at the desired location.

The gauge is sheet on the press with the prong or blade point I6, running the point I6 along the inner surface of the sheet for some distance, then piercing it again, thereby locking the gauge to the draw sheet. When the head of the gauge I I has reached the correct position for the particular stock'to be printed, and if the stock is thin, the teeth I1, I! on the head are forced and anchored in the draw sheet. After this the end of tongue I0 is inserted through the slot 2I or slot 22, depending upon whether the work is to be close gauge or not. Portion 23 and projections I5, I5 are moved along slot II until tongue II) has reached its appropriate position. As the stock varies or changes it is necessary to disengage teeth I'I, I1 and slide the gauge bodily up or down until the proper position is reached, but this movement is very slight. The gauge, after this adjustment, must again ,be anchored, and this time it will be by teeth I8, I9, 20 on one side of the wedge shape tail. When the wedge and body are again adjusted it will be'an chored by teeth I8, I9, 20 on the other side of the wedge shape tail. In other words only one of each set of teeth on the tail will engage and anchor into the draw sheet at a time. In this manner the draw sheet is only punctured by each set of teeth on every third adjustment so that the openings formed are not so close together that they join each other and form large holes in the draw sheet destroying the anchoring eifect.

Where heavy stock requiring little adjustment is to be printed, but which would apply so much forceto the gauge that teeth H, H, on the head would not anchor it, or where great precision is necessary on light stock, movement of the gauge may be prevented and anchoring successfully attained by forcing all of the teeth IT, IT, I8, IS, IS, I9, 29 and 20 into the draw sheet and an choring all of them. In this manner staggering or oiT-setting the teeth I8, I8, I9, I9, 2i], 20 to form a wedge shape tail, and providing a moment arm of maximum length between anchoring points, with a minimum of'material, results in tions I5, I5 and the been adjusted.

positioned by piercing the draw resisting to a maximum degree all attempts to rotate or pivot the gauge. The use of sealing wax is not necessary when this gauge is employed and results in an easily removable and adjustable gauge. It saves much of the printers time and eliminates the sticky and undesirable effect of such wax which penetrates the drawsheet and gauge and destroys adjustment of the tongue 01 pill.

The body portion lIof-the gauge is of curved formation lengthwise, and the resilient tongue I0 conforms to this curvature. The resilient projecportion 23. tend to move toward each other producing a tight frictional engagement with the body II of the gauge, maintaining the tongue in the position where it has Tongues or pins of varying lengths may be employed to accommodate the various types of stock printed.
