WORK GAGING AND HOLDING MEAN S.

Specification of Letters Patent.

Patented Apr. 16, 1912.

Application filed April 27, 1911. Serial No. 623,790.

To all whom it may concern:

Be it known that I, FREDERICK W. AL- BRECI-Il, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Work Gaging and Holding Means; and I do hereby declarethe 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 figures of reference marked thereon, which form a part of this specification.

My invention relates to means for gaging the position of and holding'materials preparatory to cutting or otherwise acting thereon, ence to use in printing olfices for use in connection with machines for the cutting and trimming of slugs, cuts or the like, it may be used in any other connection for which it may be adapted or appropriate.

The object of my invention is the provision in an apparatus ofthis character of simple and improved gage adjusting means for permitting an easy, quick and accurate adjustment of the gage-block as the measurement desired may require.

A further object of my invention is the provision of simple, improved and easily operated means for clamping the work to be acted on, whereby to enhance the practicability and commercial value of apparatus of this class.

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,-

Figure 1 is a plan view of an apparatus embodying my invention with parts of the same broken away. Fig. 2 is a front side view thereof. Fig. 3 is an end view thereof. Figs. 4, 5 and 6 are sections on the lines 4-4, 55 and 66, respectively, in Fig. 1.

Referring to the drawings, 1 designates a table, plate, or other suitable part, upon which the mechanism comprising my invention may be mounted. This table, if it is desired to move the work which is clamped thereto, as hereinafter described, to a saw,

and while it has particular refer-,

knife or other trimming member with which I it may be associated, may be suitably mounted for reciprocatory movements on the frame or top of a machine or other apparatus to which it may be attached. As the invention consists in the gage block adjusting feature and in the work clamping means for use in any connection for which they are adapted, they are not shown in connection with any particular machine.

Fixed to the top of the table 1, in the present instance transversely thereof, is a guide-bar 2 which is provided on its top longitudinally thereof with a series of diagonally disposed threads, 3, which, if the apparatus is to be used in a printing office in connection with the cutting of slugs, cuts or the like, preferably measure one pica from center to center thereof longitudinally of the guide-bar. The bar 2 is preferably graduated on its top adjacent one edge thereof to designate picas or other units of measurement, as indicated in Fig. 1.

The gage block 4 of the apparatus is provided on its under side with a transverse groove or recess 6 of suitable size to fit closely over the guide-bar 2 to permit the gage-block 4 to be moved longitudinally thereof or to be raised from engagement therewith, as desired. The head 5 of the gage-block is. provided in its top longitudinally of the block witha recess 7, which opens into the groove 6 of the block. Closing the end portions of'the recess 7 and rising above the top of the head 5 are bearing bosses 8 and 9 through which a micrometer adjusting screw 10 projects and has its bearings. The bearing opening in the boss 8 is of suitable size to receive acylindrical enlargement 11 at the head end of the screw 10, at the outer end of which enlargement is formed a screw head 12,

which is preferably knurled to facilitate a V turning of the same. In the bearing openend of the bushing 13 to cooperate with a shoulder 16 on the screw to prevent longitudinal movements of the screw within the bushing, while the other end of the pin 14 has a nut 17 threaded thereto without the headed end of the screw, as shown. The screw 10 is threaded through a nut 18, which fits within the recess 7 for longitudinal movements therein and has its under side provided with teeth 19 of suitable form for meshing with the teeth 3 on the guide bar 2. To adjust the screw 10 longitudinally within the boss bearings, it is only necessary to turn the bushing 13 for such purpose. It is apparent with this construction that a turning of the adjusting screw 10 will impart movement to the nut 18 transversely of the bar 2 and effect a consequent adjustment of the gage-block 4 relative to the bar 2, due to the cooperating action of the nut and bar teeth during such movement. The threads of the screw 10 are preferably of such pitch that a complete turn of the screw within the nut 18 will move the nut a suflicientdistance transversely of the bar 2 to move the gage-block a distance equal to one pica or other unit of measurement for which the threads may be adapted. The enlarged portion 11 of the screw is preferably provided therearound with a series of recesses 11 with which a spring pressed detent 20 which is mounted in a socket 21 in the gage-block is adapted to engage to yieldingly resist a turning of the screw at predetermined points in a revolution thereof to indicate nonpareils or other fractional points of adjustment of the units of measurement used. The enlargement 11 may also, if desired, be provided with graduations for registering with a fixed point on the boss 8 to indicate the degree of turning of the same.

With the gage adjusting mechanism above described a rapid and accurate adjustment of the gage-block is possible, as a quick movement of the block from one unit designation to another can be obtained by raising the block sufficiently to disengage the threads of the nut 18 from those of the guide-bar 2, after which the gageblock can be moved to any desired position of unit adjustment and then lowered to engage the nut threads with those of the bar. If it is then desired to secure an adjustment of the gage-block which is fractional to the unit designations, the adjusting screw 10 is turned until the inner edge of the gage block has reached, the desired position intermediate the unit designations. As, for instance, should it be desired to cut a piece into a length equal to 10 picas and 3 points, the gage-block is placed with its inner edge in register with either the 10 or the 11 pica mark and the screw 10 is then turned to move the nut 18 in the proper direction to place the gageblock edge at the desired position intermediate said pica marks, as is apparent.

The means employed for clamping the work while being cut or otherwise acted on comprises a clamping-block or finger 22, which is fixed to and movable with a longitudinally shiftable bar 23 one end portion of which is slidingly mounted in a block 24:, which is pivoted for vertical turning movements in a standard 25 rising from the table 1, while its other end is slidingly mounted in a standard 26 rising from the table 1. The block 22 and bar 23 are shown in the present instance as being prevented from turning by a bar 27 which projects loosely through a part of the clamping block 22, and has its ends secured in the block 24; and standard 26. The clamping block 22 is intended to act in opposition to the guide-bar 2 in clamping and holding a piece of work in position while being operated on, and is freely movable with the bar 23 toward or away from the guide-bar 2.

In order to secure the clamping-block 22 and its bar 23 in clamped position, the bar 23 is preferably serrated longitudinally on its under side for a portion of its length, and cooperating with such serrated portion is a serrated bar-holding member 28, which is mounted for vertical movements in a portion of the standard 26. The member 28 is carried by an eccentric portion 29 of a shaft 30 which is journaled in the standard 26 and has a lever arm 31 projecting from its outer end by means of which it is turned. It is apparent that a turning of the shaft 30 in one direction or the other will effect either a raisin of the member 28 in holding engagement with the bar 23 or a lowering of such member from bar holding position as desired. The shaft 30 is held within the standard 26 by a set-screw 32, the inner end of which fits within a peripheral groove in a portion of the shaft.

The standard 26 is shown as being clamped to the table 1 by the engagement of the head of a clamping screw 33 with a flange on said standard, said screw being threaded into the table 1 and having one side of its head cutaway to adapt the screw to release said flange when the cutaway portion of its head has been turned into register with the flange, as is apparent. The purpose of securing the standard 26 in this manner to the table 1 is to facilitate an easy disengagement of the same from the table to permit a raising of such standard, the clamping block 22, and the bars 23 and 27 with the block 24 as the pivot thereof, to placesaid parts out of work obstructing position when desired. In the clamping of work to the guide-bar 2, the bar 23 is moved longitudinally to place the block 22 in clamping engagement with the work in opposition to said guide-bar, after which the lever 31 is moved to effect a raising of the bar holding member 28 in looking engagement with the serrated surface of the bar 23. The work is now clamped in position to be sawed, trimmed or otherwise acted on.

I wish it understood that my invention is not limited to any specific construction or arrangement of the parts except in so far as limitations are specified in the claims.
