AUTOMATIC GAGE.

Application filed June 4,

automatic gages, nd more particularly to gages designed to be used on linotype saws, an object of the invention being to eliminate as far as possible the necessity of handwork in spacing matter to fit ruled book headings and the like.

A further object is to provide a gage of the character stated which can be used in connection with any ordinary type of linotype saw and which will operate to hold the slugs in position for cutting off the ends of the slugs so that the matter set up will he in exact conformity in size and in spaced relation to the headings desired without the necessity ofmeasuring with a rule the exact distances and proportions in picas and points.

A further object is to provide improvements of the character stated which result in an economy of time and labor and give more accurate results than possible under ordinary methods.

l/Vith these and other objects in view the invention consists in certain novel features of. construction, and combinations and ar-' rangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings Figure 1 is a view in front elevation illustrating my improvements in connection with a well-known type of saw trimmer in general use.

2 is secured by means of screws 3 or other approved attaching means. 011 the plate 2 I provide a pair of standards 4 and 5 in which the reduced'ends 6' of an adjusting shaft 7 have rotary mounting, the standards operating to hold the shaft against longitudinal movement. A finger hold or hand wheel 7 is secured on one end 6 to facilitate theturning of the shaft.

This shaft 7 is in reality an adjusting screw and is provided at one end with screw threads 8 and at its other end with screw threads 9. These screw threads are of different pitch, the threads 8 being of exactly twice the pitch of the threads 9, or,in' other words, there are twice as many threads 9 to the inch as there are threads 8 for a purpose which will hereinafter appear.

The threaded portions 8 and 9 project through internally screw threaded burs or H riders 10 and 11 respectively. These burs Or riders have dove tailed grooves 12 in their lower faces receiving dove tailed tenons 13 on blocks 14 and 15 respectively. The burs and the blocks are coupled against accidental movement by means of removable pins '16 which project through the burs and into the blocks as. shown clearly 'in Fig. 4, so that the blocks are moved by the turning movement of the screws.

These blocks 14 and 15 are provided with laterally projecting arms 17 and 18 respec 'tively and said arms 17 and 18 are made with alined circular openings 19 to receive and support a rod 20, the latter having at its forward end a T-head 21. A dog 22 is pivotally connected to the arm 17 as shown at 23, and'is pressed downwardly against the rod 20 by means of a spring 24.

The rod 20 at one end is made with a flattened portion 25 WhlCl1,'Lt its point of juncture with the circular or cylindrical portion of the rod, forms a shoulder 26 for a purpose which will hereinafter appear.

A stationary'spring pressed gage plate 27 is supported on mod 28 mounted in brackets 29 on the plate 2 and at its free edge is downwardly pressed by means of a spring 30 on one end ofthe rodand a finger hold 31v is provided on the extreme end of the rod to permit the gageplate 27 to be elevated This spool 32 is adapted to support'a copy' strip 35 which we will assume contains the column headings desired to be set up, and this copy strip 35 is fed under the gage plate 27.

A second and movable gage plate 36 is mounted in upright 37 on a platform 38 which constitutes an integral part of the block 14'. This gage plate 36 is operatively connected to a supporting rod 37, the latter provided with a spring 39 to press the free edge of the gage plate downwardly and a finger hold or knob l0 is provided on the rod to adjust or move the gage plate vertically. The copy strip 35 is positioned under this gage plate 36 and the inner or adjacent edges of the gage plates 27 and 36 are adapted to register with the sides of the column to be set up as will be explained.

I have illustrated at 41 a rotary saw such as commonly employed, but have not at tempted to illustrate the particular manner of operating the saw or moving the same toward the plate'2 or the latter toward the saw as may be desired, but it is to be understood that these parts operate in the ordinary way with machines of the same general type in use.

I have illustrated in Fig. 1 in side elevation an ordinary form of saw trimmer for the purpose of locating my improved mechanism thereon, but as the details of this trimmer form no part of my invention, it is not necessary to describe the same in detail.

42 represents linotype slugs which are adapted to be placed beside a guide plate 43 at one edge of the plate 2 and supported upon an extension 44 for the cutting operation, as will now be described.

The copy strip 35 is projected under the gage plate 27 and also under the gage plate 36; the rig being in normal position, the gage plate 36 and bur 10 and projecting arm 1'? appear one inch farther to the right than shown in Fig. 2, and line up against and with the inside edge of gage plate 27; bur 11 and projecting arm 18 being one hall inch farther to the right than shown in Fig. 2, bringing bur 11 up flush against the inside edge of a standard 5; T-head 21 resting against projecting arm 18 (as shown in Fig. 2) would then be one-half inch farther to the right, also, than is shown in Fig. 2. Now. by drawing T-head 21 to right until dog 22 engages flattened portion 25 of rod 20 and rod 20 is held inwardly until the dog 22 engages the left shoulder 26 on the rod 20, the right hand face of T-head 21 will register flush with saw trimmer line. Let us understand that inside edge of gage plate 36 is now clamped in register with the left hand side of column on copy strip 35. Tension gage plate 27 is released and shaft 7 is now turned to move the gage plate 36 with the copy strip 35 to the left until the right hand side vertical ruling of columns on copy strip 35 appears in register with inside edge of gage plate 27 as is shown in Fig. 2. At this juncture gage plate 36, bur 10 and projecting arm 19, and bur 11 and projecting arm 18, will be exactly in position shown in Fig. 2.

In turning the shaft 7 the burs or riders 10 and 11 are caused to move longitudinally, but due to the different pitch and number oi teeth on the sections 8 and 9, the bur 10 will be moved exactly twice the distance or the movement of the bur 11, as shown in Fig. 2. In placing the slugs 42 to be sawed, the dog 22 is held in an elevated position; slugs e2 placed against T-head and pressed inwardly, causing a longitudinal movement of that portion of rod 20 bearing shoulder 26 to pass free to left under dog 22 until T-head is stopped in contact with the projecting arm 18, as shown in Fig. 2, leaving the slugs projected beyond the edge of plate 2 to be sawed exactly one-half the distance from the center of the slugs tov the saw trimmer line of the distance of the movement imparted to the bur 10 in order to register the right-hand side of the column on copy strip 35 with gage plate 27. The slugs are then in the position for cutting off the metal at one end thereof, and this operation is carried out by means of the saw 41. The slugs are then reversed in position and the T-head 21 drawn outwardly until the dog 22 engages the flat portion 25 of the rod 20 when the rod 20 is moved inwardly until the dog 22 engages the shoulder 26 on the rod 20, and when in this'position, the T- head 21 will hold the slugs projected a dis tance exactly equal to the distance they were projected before so that the opposite ends of the slugs can be cut off and the lengths of the slugs left will be in exact accordance with'thc width of the column on the copy strip.

It is therefore apparent that with my invention it is not necessary to calculate in picas and points the particular measurements needed for cutting oil the ends of the slug as the movement of the plate 36 will be equal to the complete length of slug to be cut oil, but this length is equally proportioned between the ends of the slugs by reason of the operation above described.

l' w hen it is desired to adjust the parts, the pins 16 can be removed and the blocks 14 and 15 moved transversely of the plate to disconnect them from the burs so that the burs can be quickly moved by turning the screw and the blocks replaced in operative position thereto at any desired starting point of the operation.

Various slight changes might be made in the general form and arrangement of parts described without departing from the invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changesand rod, and movable coupling means connectalterations as fairly fall within the spirit and scope of the appended claims.
