T 0 all whom it may concern:

Be it known that we, FRED L. ELLIOTT and GEORGE E. ECKERSTROM, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Printers Lead and Rule Gutters; and we do 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.

This invention relates to improvements in printers? lead and rule cutters.

One object of the invention is to provide a machine of this character having an improved construction of adjustable gage adapted to be set for gaging leads, rules, slugs and the like of any desired length.

Another object is to provide a lead and rule cutter having means whereby thin material will be securely held and prevented from curling up while being out.

With the foregoing and other objects in view, the invention consists of certain novel features of construction combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a side view of a rule and lead cutting machine constructed in accordance with the invention; Fig. 2 is a top plan view of the same; Fig. 3 is an end view thereof; Fig. 4: is a vertical longitudinal section on the line 1-4: of Fig. 2; Fig. 5 is a vertical section on the line 5-5 of Fig. 2; Fig. 6 is an enlarged vertical sectional view of the adjustable stop for holding the material at the desired position for being out; Fig. 7 is a detail perspective view of the plate for making point adjustments.

In the embodiment of the invention we provide a supporting frame 1 having at its opposite ends suitable supporting legs 2 whereby the same may be secured to a bench or other support. On one end of the frame is secured a stationary material supporting table 3 while on the opposite end of the frame is mounted a spring cutting table 4, said table being pivotally or hingedly connected at its outer end to the adjacent end of the table and is provided on its opposite side edges adjacent to'its inner end with laterally projecting supporting lugs 5 which are slidably engaged with slots formed in the inner sides of spring sockets 6 arranged on opposite sides of the frame 1 as shown. In the sockets 6 are arranged coiled springs 7 with the upper ends of which are engaged the lugs 5 whereby the inner end of the table is yieldingly supported and held in position to receive the material from the stationary table 8. In the upper ends of the sockets 6 are arranged screw plugs 8 which prevent the lugs from being disengaged from the upper ends of the socket.

On the lower portion of the frame 1 is arranged a longitudinally disposed rack bar 9 the notches in which represent half pica lengths. Slidably engaged with the rack bar 9 is an adjustable stop block 10 the upper end of which projects through a longitudinally disposed slot 11 formed in the table 4t and extending throughout the length of the same. The stop block 10 is provided with a toothed pawl 12 which is held in operative engagement with the rack bar 9 by a suitable spring 13. Pivotally connected to the opposite sides of the block 10 below the table 4 is the bifurcated lower end of a pawl releasing lever 15, the upper or handle end of which projects through the slot 11 and is provided with a thumb piece whereby said lever may be depressed thereby rocking the pawl 12 and disengaging the teeth thereof from the teeth of the rack bar. When the pawl is thus disengaged from the rack bar the stop block may be adjusted longitudinally in the frame to provide a stop which will enable the material to be out off at any desired length. a

The upper portion 16 of the stop block or the portion engaged by the material to be cut is separate from the lower portion of the block and is adjust-ably secured to said lower portion by a set screw 17, which is en-' gaged with a slot invsaid upper portion 16 of the block. By thus connecting the upper portion 16 of the block to the lower portion, said upper portion may be adjusted longitudinally to provide for the more accurate cutting of the rules or leads in the desired lengths.

In order that the materialv may be out into lengths known as points we provide an adjustable point marking plate 18, said plate being preferably constructed in the form of a cross or provided with radially projecting lugs a, b, c and cl. The plate 18 is revolubly mounted in a slot 19 formed in the forward upper portion of the stop block and is adapted to be turned in said slot to bring different lugs into operative posit-ion with respect to the end of the block, so that said ends may be lengthened or shortened thus enabling point length adjustments to be made by the block 10. As is well known in the printing art, twelve points represent one pica, it should be desired to cut a rule often points length or be set to the one pica position on the rack bar and table after which the plate 18 would be adjusted in the block to bring the lug 0 into operative projects beyond the distance of a space of ten the end of the stop block to two points thereby forming this length. In the same manner if an eight point lead or rule was desired the plate would be revolved to lug will project four blade and the end not desired to use the plate 18 the latter is turned to bring the lug marked cl into position, said lug edge of the stop thereby making said plate ineffective.

bracket secured to one side as shown.

of a stop block The table 4 is provided on its upper side adjacent one edge of the slot 11 formed therein with a pica scale of measurement reading from one pica to forty-two picas. The rack bar 9 corresponds in length to the length of said pica scale and the stop block 10 is adapted to be adjusted on said rack bar to the distance of forty-two picas. Should it be desired to cut leads or rules of greater length than forty-two picas, the length of said rules or leads will be measured by a supplemental gage bar 22 which is slidably mounted in a suitable guide bracket 23 arranged on the lower side of the frame adj acent to its outer end as shown. The gage bar 22 is provided on its outer end with an upwardly and inwardly projecting stop arm 24 the inner end of which is provided with a head25 having a square inner face adapted to receive the end of the rule or lead to be out. In one side of the gage bar 22 is formed a series of notches which are spaced apart at full pica lengths. The bar 22 is rigidly secured in its adjusted position by a locking pawl 26 which is pivotally conso that, for instance, if-

spaces, the stop block wouldposition wherein the same points in length with which the rule or lead is engaged for being out to;

bring the lug Z) into operative position, in which position said points beyond the end; of the stop block thereby forming a space of eight points in length between the cutting of the lug b. When it is;

being of such length that the outer edge thereof is flush with the outer,

The plate 18 is fastened in its; adjusted position by a set screw 20 which; has a screw threaded engagement with a The set screw is provided witha reduced inner end which is adapted to be nected to the outer end of the frame and is provided with a notched inner end adapted to be brought into engagement with the notches in the adjusting bar whereby the latter will be securely held against longitudinal movement in either direction.

The cutting mechanism of the machine comprises a blade carrying arm 27 one end of which is pivotally mounted on a bearing stud 28 formed on the rear side of one end of the frame as shown. The arm 27 has secured thereto a downwardly projecting cutting blade 29 which is adapted to be brought into engagement with the material to be cut when the arm 27 is swung clownwardly. The blade carrying arm is operated by a raising and lowering lever 30. The lever 30 is fixedly mounted on one end of a rock shaft 31 which is journaled in suitable bearings in the opposite side of the frame over the stud 28 on which the arm 27 is mounted. The shaft 31 projects through a guide slot formed in the adjacent end of the blade carrying arm 27 whereby said arm is guided in its movement and on the adjacent end of said shaft is secured a cam head 32 which is adapted to work in an oval shaped recess 33 formed in the adjacent end of the arm 27 whereby when said shaft and cam head are turned in one direction by the lever 30, the arm 27 will be raised or lowered thereby bringing the edge of the blade into engagement with the strip of material for cutting off leads or rules of the desired length. The arm 27 is limited in its downward movement by a stop lug 34 arranged on one side of the shaft bearing of the supporting frame as shown.

The table 3 of the machine is provided on its lower edge with a supporting flange 35 while thespring table 4 is provided with work or material receiving lugs 36 having dovetail shaped lower edges which are adapted to slidably engage a dovetail shaped groove or channel 37 formed in the lower portion of the table 4 whereby said lugs 36 are held in adjustable engagement with the table and in line with the flange 35 on the table 34. By means of the lugs 36 the end of the strip ofmaterial will be held square while being cut. By hingedly connecting the cutting table 4 and yieldably supporting the inner end thereof, said end will move down under the pressure of the blade when the strip is cutthereby holding the end of the strip and preventing the same from curling up while being cut.

'From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.
