specification.

My invention relates to improvements in Vises and is particularly adapted for use in connection with machines for cutting lino typeslugs and other material used in the printing art.

My invention is preferably used in connection with devices for cutting linotype slugs. \Associated with such a device is a gage for positioning the work with respect to the cutting and trimming device and my 'vise is particularly. adapted to cooperate with this gage to securely hold the work in position during the cutting operation.

The various objects and advantages of my invention will appear more fully hereinafter in the specification and claims.

For the purpose of illustrating my invention,Ihave shown one form thereofand one application thereof in the accompanying drawing. y

Fig. -18 is asection taken on the line view of a detachable face piece for the gage, andFig. 20 is a plan view showing a secondary work-holding vise.

In the construction illustrated, .I provide a table 20,having asliding work supporting section 21. This table is mounted on. a suitable standard on which is also mounted a rotating shaft 22, carrying at one end a rotary cutting tool 23 and at the other end a grinding wheel 24. The cutting tool 23 com prises a combined saw and trimmer, the saw being mounted ona head 25 and having an opening or openings therein, through which project trimmer knives 26 mountedin the ead 25 and removably secured in position by screws or other securing means 27.

Onthe front part of the table is a gage mechanism by which the material to be cut and trimmed may be properly positioned relatively to the cutting tool. This gage comprises a gage plate 28, which has extending therethrough a follower pin 29 having an are shaped extension rigid relative to the gage plate and adapted to extend into an 1818 of Fig. 17. Fig. 19 is a perspective arc-shaped groove 30' formed in the table, I

this groove being so arranged that when the gage plateis swung around, it will be moved in the arc of a circle having its center on the line dent of the cutting tool 23. A lockmg pin 31, inserted through the gage plate,

ts in openings on the sliding table to lock the gage plate in the position to which it may be moved. The movable member of the gage comprises an arm 32, having-a straight edge" which extends at an angle to t'he straight; edge of the gage-plate 28 and is provided with a bracket 33, carrying a screw member 34. This screw removably engages the teeth of a rack- 35 formed on the upper face of the gage plate, and by rotating the screw the work is properly positioned with respect-to the cutting tool. A suitable slot 36 is formed on the upper face of the gage plate and in this slot 1s adapted to fit a'rib member extending downwardly from the bracket 33 whereby the arm 32 is slidably the under side'of the casing at its forward eled as at 55 and from the v1se bar 38v and is "to engage the rear of t supported on the gage plate 28. The threads of the rack 35 and the threads of the screw 34 are cut to have a pitch based on a point as a unit of measurement whereby the movable member 32 may be adjusted accurately relatively to the cutting tool by units of measurement used in the printing art. The trimmer knives 26 being adjustable, they may be set with reference to the gage arm thereby insuring accuracy under all conditions. 1

For holding the material to be cut in the gage, I provide a suitable vise, which is removably fastened on-the sliding table and lies parallel with the cutting tool 23. This vise comprises a casing 37, a movable vise bar 38, a stop member or ratchet bar 39, and

mechanism for connecting the movable mem her with the ratchet bar. The forward end of the casing has secured therein a guide 40, which is sufficiently spaced from the back of the casing to permit the vise member to move between said casing and the guide, and is recessed on its upper side to receive the forward end of the ratchet bar 39. On

end is provided a locking pin 41, which is adapted to fit in anflopening formed in the table to hold thp vise in position. The rear end of the casing is also provided with a guide block 42, suitably spaced from the back of the casing to permit the vise bar 38 to slide therebetween, and is recessed on its upper side to W ratchet bar. Extending laterally from the guide block 42 is a bifurcated foot 43 arranged to be engaged by, a clamping screw 44 to hold the rear end of the vise in position. Extending rearwardly from the guide block42 is a spring housing 45, in which is arranged a'coil spring 46, adapted to fit over the end of the ratchet bar 39. It will be noted that the end of the ratchet bar is provided with a reduced end portion 47, over which the coil spring is adapted to fit. By this arrangement, the spring is properly centered and any tendency on the part of the spring to bind against the sides of its housing is prevented. The rear end of the housing is closed by a screw 48, by which the tension of the spring may be adjusted. The vise bar 38 is connected to the ratchet bar 39 by a pawl 49 which is. ivoted upon a pin 50, extending laterally romone end of a lever head '51. This lever head is pivotally mounted upon a stud 52,-extending laterally rovidedwith an inwardly extending stop pin 53, ada ted to operate in an opening 54 formed in t e vise bar. The pawl 49 on its under side is beva flat spring 56 having one end engaging the pin 53 and passing over the stud 52, has its 0 posite end arranged e pawl, flat spring 56 engaging the bevel face 55 of the pawl or receive the rear end of the the straight rear edge of the pawl will maintain the pawl in the two positions in which it may be moved. On the under side of the pawl, near its outer end, is provided a downwardly extending pin 57 adapted to throw the pawl upwardly when the front end of the lever head is thrown up. In Fig. 2 in full lines the pawl is shown out of its locked position. Assuming that it is desired to release the material the outer end of the lever or handle 59 is raised. This lowers the pawl out of engagement with the rack and due to the engagement of the spring 56 with the beveled edge of the pawl, the awl will move with the lever head. In raising the lever 59, however, it is not raised sufiiciently to cause the pin 57 to engage the bottom of the casing. In order to cause the pawl to again engage the rack in position to place the spring '46 under tension, the lever is raised far enough to cause the pin 57 to engage the bottom of the casing. This moves the front end of the pawl upwardly, and after the beveled edge 55 has passed oif the spring 56, the pawl willbe snapped up wardly into an engaging position by the action of the spring. The upper end of the lever head is provided with a'socket 58, in

which is fastened a lever or handle 59.

Describing the operation of the apparatusthus far described, it will be assumed that it is desired to out a number of linotype ing the point as a unit of measurement. Under these conditions,the.movable member 32 of the gage is advanced by turning the screw 34 until the proper length is reached, as indicated by indicating marks on the upper face of the rack 35 and by graduated marks on the bracket 33 and screw 34. The slugs are then placed in position in the gage as shown in Fig. 1 and the handle 59 is pulled forward by the operator. Thismoves the vise bar 38 forward until'its front edge engages the slugs. The operator then moves the handle downward, which tilts the lever head, throwing the pawl 49 upward and into engagement with the rack on the ratchet bar 39. The pawl in connection with'the lever. head new forms a toggle havingone end in engagement with the ratchet bar 39 and the other end connected on the stud 52. The throwing of the center of the toggle thus formed, upwardly advances the visebar38 hard against the slugs and the rest of the movement of the toggle is taken up by a rearward movement of the ratchet bar 39' against the spring 46. When the center of the toggle asses the line extending from the point 0? engagement of the pawl with the ratchet to thestud 52, the vise bar will 'be securely locked 1against rearward move-' ment and will be d in resilient engageslugs down to a predetermined length, havreeured, irrespective of the rying with it the slugs, which will be cut and trimmed by the cutting tool '23. When it is desired to move the work from the vise, the handle 59 is raised, thereby throwing the center of the toggle downward and disconnecting the pawl from the ratchet 39.

In Figs. '-7 and 8, I have illustrated a means for cut-ting a miter on the end of the slug. This is particularly advantageous Where the slug is adapted to be used for corners or the like and it is desired to get an accurate, fit. In Fig. 7, I have shown the gage swung around until the straight edge of the member 32 extends substantially at an angle of 45 with respect to the line of cut. Under these conditions, the vise bar engaging the slug or slugs might tend to force the same slightly out of position, thereby spoiling the accuracy of the cut. I have, therefore provided a holdin block 60, which may be inserted between t e vise bar and the material to be cut. This block has its front end beveled so that it can be placed in close proximity to the cut and is provided with a notch 61, having one face thereof so arranged that it will present a flat surface to be engaged by the vise bar 38. The rear end of the block is rovided with a downwardly, extending pm 62 adapted to fit in suitably spaced openings 64 in the top of the table. These openings are so spaced that Itheblock'will be spaced :1. given distance from the edge of the plate 28, this distance being based on the point as a unit of measurement. It will be noted that when the work to be held in position is placed along the strai ht edge of the plate 28 of the gage and the hlockplaced in the opening nearest the work to be cut, the vise member can now be moved forward and the block will-be. 'firmly forced against the work to be out. This is particularly advanta eous when two mitered, sides are to be use and the cut is to be made with absolute accuracy.

In Figs. 8 and 10, I have illustrated a different form of holding block. This block may be used in the same connection as the block. illustrated in Fig. 7, butais particu larly. adapted where the angle of the cut is greater or less than 45. Under these circumstances, when it is desired to get a wide bearing surface against the work, a triangular block such as 65 maybe used. This block is provided with a tongue 66, adapted to slide in a correspondingly shaped slot 67 formed in the top of the table. Blocks simi-' lar to 65, having different angles, may be providedso that a'flatengagement may be angle to which. the gage is moved.

In Fig. 11, I have illustrated Sana.

' other form of holding block, which may be attached directly to the end of the vise bar. In this instance, the block consists of astraight edge. 68, havingaslo'ttherein to fit otter the is illustrat end of the vise bar 38 and provided with a screw 69 for fastening the same in position. This block may be." used when it is desired to get a wide bearing surface against the material to be cut and'the material to be cut isf adapted to lie at right angles to the line 0 cute In Figs,--17, 18 and 19, I have illustrated an arrangement whereby very short pieces of material may be cut, and the gage used for measuring these'short pieces. It will be noted that the bearing face of the movable member of the gage cannot be moved up to the line of out due to the position of the vise on the table. In order that the gage may be moved closer to the line ofcut, the face of the straight edge may be formed 'with a recess 70 and the side of the vise bar formed with recsses' 71 and a projection or rib 7 2, the recesses 71 receiving the ribs on the, frontface of the movable member 32 and the projection 72 being adapted to fit into the recess 70 formed on the front face of the movable member32. By this arrangement, the gage may be moved very close to the line of cut as illustrated in Fig. 17.

In Fig. 19, I have illustrated a detachable front face for the movable member. 32. It is frequently for certain purposes desired that the straight edge of-themovable member 32 be made perfectly fiat, therefore, in order that very short lengths of material may be cut and at the same time measured by the gage, I have provided this removable face 73, illustrated in Fig. ,19. In practice, the space between the line of cut and the face of the movable member of the gage is two picas. In order that a slug less than two picas may be measured and cut, I provide this detachable face member 73, which has asliding engagement with the vise bar 38 and'is exactly two picas wide and recessed to the depth of one pica. By this arrangement, the movable member 32 with the removable face may combine to give an exact measurement down to one pica on the work to be cut. member may take most any shape but is preferably constructed as illustrated in the This removable face 1 mental vise member. It will be note by reference to Fig. 7 or 8 that when a mitered or beveled cutis being -made, there is quite a portion of the slug which extends beyond the inside end of the plate 28. It sometimes occurs, due to the fact-that this end is not 'rigidly supported or. backed up, that the I cutting: device will throw a slight bur on -the material, thereby decreasing the absolute accuracy of the work turned out by the machine. In order to overcome this, "I provide the su plemental vise member which ed in Fig. 20. This vise member,

it will be noted, comprises a block 74 which is held in position on the slidin section 21 of the table by a bolt 75, extending into the groove 30 and by a small dowel pin 76, adapted to fit in a suitable opening or hole in the top of the table. The movable vise member 77 of the sup lemental vise comprises a triangular bloc as shown having a rearwardly extending pin 78 adapted to fit in an opening formed in the block 74 and this movable member is actuated by a screw 79. In operation in order to back the material up, the slug is inserted in position just as is shown in Fig. 7, the second iece of work 80 is inserted in position as in Fig. 20, and the movable member of the vise is then screwed tight to hold the work in position. The sliding table 21 may now be moved for ward and the cut made by the cutting tool. It will be noted that when the out ismade, not only is the slug cut, but the second piece of work 80 is'also cut. The slug is thus supported or reinforced at the cutting edge and a fin or bur is prevented.

While I have shown and described certain constructions in the drawings and specification, it will be understood that various modifications and chan es may be, made therein without departing roin the spirit of my invention, as set forth in the appended claims.
