Specification of Letters Patent. (application filed March 1,

. I :1 W4 To (all whom, it nanny concern:

Be it known that I, Gnomes M. DURELL, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Ga re Attachments for Lead-Cutters, &c.; an 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 appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to adjustable age attachments for use on lead-cutters or t c class of trimmers and rotary saws employed by printers for the accurate trimming or cutting of leads, cuts, rules, or the like.

The object of my invention is to provide an attachment of this class that is simple and efiicient in its construction and operation and has its gage adapted for quick adIKu'stment over wide spaces and also adjustab e to points.

A further object of my invention is the provision of a gage attachment having its uiding member adjustable longitudinally o the bed of the machine to permit an adjustment of the graduation-scale with res ect to the cutting element to compehsate or wear or springing of the shearing parts and also to permit the capacity of the machine to be doubled.

The invention is fully described in the following specification and shown in the accompanying drawings, in which Figure 1 is a plan view of the bed of a cutter with one form of my attachment mounted thereon. Figs. 2 and 3 are sectional views taken, res ectively, on the dotted lines a: a: and y y in i i 1 Fig. 4 is a side elevation of the cam-locking lever. Fig. 5 is a plan view of the cutter-bed with the gage attachment removed. Fig. 6 is an end View of the cam- Fi 7 is a rear end elevation of the gage-block s own in Fig. 1. Fig. 8 is a crosssection taken on the dotted line m a in Fig. 7. Fig. 9 is a modification oi the ga eblock, the same being provided with m ependent point-adjusting means. Fig. ll) is a plan of a lead-cutter with the uide and gage extended longitudinally of itsied. F' s. 11 and 12 are details of one form of point-a just- Patented March 6, 1906. 1905.

ing Wheel of my invention. Fig. 13 is a rear end view of Figs. 15 and 16. Fig. 14 is a crosssection taken on the dotted line 1; y in Fig. 16; and Fig. 15 is a plan view, and Fig. 16 a central longitudinal section, of a modified form of my invention with point-adjusting attachment.

Referring to the several figures oi the drawings, 1 represents the bed of a cutting or trimming device to which my invention is adapted to be attached, the right-hand edge thereof being the point from which measurement is taken. Provided longitudinally of the bed is a groove or guideway 2 for receiving the guide bar or strip 3 of my invention and in which it is lon itudinally adjustable, as hereinafter describe T heforward movement of the guide-strip 3 is limited by an end- Wise-abutting portion 4, which is formed at the extreme forward end of the bed in the path of the groove 2, as shown.

In Figs. 1, 2, and 3 the guide-strip 3 is shown as being provided on each side near its upper edges with a groove 5, extending throughout its length, and on its upper surface with equidistant notches 6, which are preferably spaced one nonpareil apart. Scale-numerals are placed at one side of the notches 6, as shown, to assist in the ready finding of the roper length of adjustment of the gagebloc Mounted to slide longitudinally on the guide-strip 3 is the gage-block 7, which has its under surface grooved or slotted to seat over the guide-strip 3 and the walls of such grooved or slotted portion formed with tongues or ribs 7 for operating within the grooves 5 of the guide-strip. The gage-block 7 has its base in engagement with the surface of the bed 1 and is formed on its upper surface bearing-lugs 8, which are positioned directly over the guide-strip 3 and have the cam-lever 9 pivotally mounted therein. The forward bearing-lug acts as the pointer for the gagehlock and is formed a distance back from the forward edge of the base of the block 7 equal to the distance of the first graduatio11mark from the front or shearin edge of the bed 1, thus adapting the forwari edge of said lug to re ister with the first point on the face of the uide-strip 3 when the forward edge of the base of the gage is laced flush with the edge of the bed. In or er to lock the age-block in adjusted position, the cam-s11 ace of the lever is formed with teeth, as shown at 9,

with the two vertical transversely-disposed for meshing with the graduation-notches 6 when the lever-handle is pressed down, thus enabling the gagc-block 7 to be quickly moved over a wide s ace on the guide-strip 3 and then locked in ad j usted position by a ma nipulation of the lever 9. The guide-strip 3 is provided on its under surface with the clongated lugs 10, which are adapted to pr'oject within the elongated slots 10 formed through the bottom of'the groove 2 of the bed and to have a limited longitudinal movement therein to permit of a slight longitudinal adjustment of the guide-strip 3 when it is desired to readjust the point of commencement of the graduation-marks on said strip with respect to the shearing edge of the bed, thus compensating for any wear on the parts and springing of the knife and permitting accurate measurement at all times. This adjustment is aided by a bolt 11, which is threaded in the rear of the bed 1 and has its inner end in engagement with the rear lug 10 of the guide-strip. The strip 3 is rigidly retained in adjusted position by means of a stem 10", projecting downwardly from each of the lugs 10 and having a flanged nut or a nut and washer threaded to its end for engaging the outer edges of the slot 10*. If it is desired to use a micrometer-gage on this construction of my invention, the gage-block shown in Fig. 9 may be substituted for the gage-block above described. In this figure, 12 represents the base ortion of the gage-block, and 13 three space bearing-lugs, which have the spindle or stem 14 mounted therein. Mounted on the spindle or stem 14 between the bearing-lugs 13 are the cam'lever 15 for engaging the guide-strip 3 and locking the gageblock against movement thereon and the micrometer or point-adjusting wheel 16, which is threaded to the stem and adapted to impart a longitudinal movement thereto when turned. At the forward end of the gageblock is disposed the separately-movable piece 17, which is secured in suitable manner to the projecting end of the stem 14 and adapted to receive a movement independent of the block 12 when the oint-wheel 16 is turned. The purpose of t e micrometer or oint-wheel is to permit the gage edge of the lilock 12 to be adjusted to a fraction of one of the points marked on the guide-strip 3, as the movable piece 17 may be adjusted by a turning of the wheel 16 to register the de sired fraction of the space between two of the notches on the guide-strip, thus permitting accurate adjustment of the gage, which is very important in the use of such machines. The surface of the point-wheel may be graduated to indicate the degree of adjustment.

In the remaining figures of the drawings are shown different views of a modification of the pointadjusting means. In this construction the guide-strip for the gage-block,

1, com rises the base-piece a, and the indepen ently-movable cappin -stri b. The base-piece is mounted on an mar e longitudinally adjustable of the bed 1 in the same manner as the guidestrip 3 and is shown as having its upper surface longitudinally grooved for receiving the tongue or rib a, formed on the under surface of the strip 1). The strip b is suitably grooved on its sides to receive the tongues or ribs 7 of the gageblock and has its upper surface graduated in a manner similar to the guide-strip 3. At the rear end of the base-piece a is secured or formed the vertical transversely-disposed bearing-lugs d, which are suitably apertured to receive the stem e, projecting longitudinally from the rear end of the top strip 6. Threaded to the stem 6 between the lugs d is a micrometer or point-wheel f, which has its surface provided with six marks or graduations to designate the six points of a nonpariel should a nonpareil graduation be employed on the guide-strip. It will thus be seen that when the gage-block has been adjusted to the desired number of nonpareils or other width of graduations on the guide-strip it may quickly be moved to the desired point of intermediate adjustment by turning the point-wheel f to indicate the point desired, thus imparting the required movement to the gage-block, which is locked to the top strip b.

in either construction of my invention the capacity of the machine to which it is attached may be doubled by removing the guide-strip from the [positions shown in Figs. 1, 3, 15, and 16 an securely fastening the forward lug 10 thereof within the rear slot 10 of the bed 1, as shown in Fig. 10. When the guide-strip is thus extended, the front end thereof may be made to register with a point say fortynonpareilsfrom the forward end of the bed 1, as shown in Fig. 10, and the gradu ation on the strip continued from such point. It will thus be seen that the gage-block of my invention may be quickly moved over wide spaces and then rigidly locked in adjusted. position to the guide-strip, that the micrometer attachment enables it to be accurately adjusted to points intermediate of the graduations on the uide-stri that the guide-strip is longitudina ly mova le to permit its position with respect to the cutting element to be changed to compensate for wear on the shearing parts or a springin of the knife, thus permitting accurate wor on old cutters, and that the uide-strip and age-block may be extendedTongitudinally of the bed of the machine to double or increase the capacity thereof.

It is obvious that such changes in the form, proportion, and minor details of construction of the parts as fairl fall within the scope of my invention may he made without de arting from the spirit or sacrificing any 0 the the form of which latter is the same as in Fig. l advantages thereof.

Having thus described my invention, What 1 claim as new, and desire to secure by Letters Patent, is-
