To all tf1/wm t waag concern.'

Be it known that I, Flinn rrenQUrs'rfa snbiect of the Kino of Sweden,'residinelat d D c:

W'orcester, in the county of l'lilorcester 'and State of lilalssachusetts, have invented anew and useful RuleFormll/fachine, of which the following is a specification. e j Y* This Vinvention relates to the slttin'g and grooving ofthe faces of c'astingmachine slugs or lines oftype for use in printing tabular work. `These slugsfare set up on a type casting machine in block, associated in snch manner 'as may be necessary to produce the particular form of tables desiied.y 'and then they are grooved transversely. In these grooves are inserted metallic rules, wires orstrips, the front edges or faces of which constitute printing surfaces for printing lines between thecolumns. Obviously these rules, and therefore the grooves, yhave to be spaced atdifferent distances apart fordifferent kinds of tabular work. All the above is well known.

The principal objects of this invention are to provide a machine` for performing this groovingoperation which will be very compact and yet will be especially efficient for the purpose intended and, `more speciiically, to provide an improved `'form of readily ad.- jnstable carriages forthe milling cutters and breaches andan improved and more cenvenie'nt method of driving the same in their different adjusted positions; to provide an accurate and efficient way for supporting the carriages independently of the arbor which rotates the milling cutters and for facilitating the spacing of the milling cutters and breaches the proper distances apart gl to provide for vertically adjusting the cutter arbor and carriage; to provide means connected therewith for widening the bottoms of the slots so that rules wider at the base than in ,the body can be inserted and thus there will be no danger of their displacement even after the type has been handled; and to provide an improved printing rule form from which the( rules cannot be removed by a .transverse motion. i: j e j j The invention also involves other improvements "and features of other parts of the machine as 1will appear.

I have shown the machine in a compact form in which it is mounted on a base or frame 10. The machine is run by a motor 11 mounted on a bracket 12 attached to the base. The bracket is adjustable on the base so as to keep the belt 13 driven from the motor sufficiently stretched. This belt drives a pulley 14 on the cutter arbor 15.

On the other end of the motor shaft 21 `is a worm 22, which drives a worm gear 23 attached to a vertical telescopingshaft 24. Unithe vertical shaft is a worm 25 drivinga 'ivorm gear 26 provided with a clutch 2T operated by a handle 29, to engage and disena feed gear shaft 2S. This is Vprovided with ' gears 33 and 35 engaging racks 36 on the table 37, which moves `very slowly. rllhe varbor 15 is mounted on ball 4bearings in adjustable slides 3&1 in the sides of the frame 10 and extends across it above. Said slides are made adjustable, through a cam shaft 31 operated by a hand wheel 32, and provided with set screws for locking it. A switch for the motor 4islocated in a convenient place in the side of the vframe with the wiring in the hollow of the base 10.

The table closes the top of the frame between the ways 38 on which the table 37 reciprocates, so that most of the mechanism is entirely enclosed. ltwill be apparent that which is provided with one stationary jaw l" tot are provided along their gripping surfaces with longitudinal grooves m 'the form of teeth running on an incline to the table.V

The loose jaw has pivots 43 on both ends. Said pivots fit in slots 44 in the end pieces of a frame and move parallel with the table. These grooves thereby prevent the slugs at the end of the series from rising and therefore tend to prevent the rest of the slugs from bulging or rising from the table when they are clamped between them. Y

The milling operation is performed by a series of thin milling cut/ters each having a flat hub 49 on each side to give it a good bearing on the arbor'. The adjustable slides 34 areV provided with bearings for the arbor 15 and with bosses 52 projecting therefrom on the opposite sides. Mounted in the bosses and extending parallel. with the arbor, and substantially at the level thereof, are two bars 53 which are shown as square. These barsare located in fixed position and constitute guides and measuring scales. For this purpose each bar is beveled off at 54 on the outer upper corner and this beveled surface is provided with V-shaped teeth 55. These teeth are spaced apart at any convenient distance, but for the purpose of ordinary tabular work in the art mentioned l' prefer to space them l of an inch from apex to apex. 0n the horizontal top of each bar is provided a scale having its division marks registering with the teeth. This is divided into picas, half-picas and two-points, picas with .the longest scale mark, half-picas with a shorter scale mark and two-point with the shortest scale mark.

On these two bars 53 are located a convenient number of cutter carriages 60. The bars therefore constitute supports and guides for these carriages, the carriages being in the form of comparatively thin strips of metal having square openings therethrough for tting the bars53. Each carriage is provided with a central vertical space 6l and with a central circular horizontal perforation 62. The arbor l5 passes through the central perforation freely and without bearing upon it. The' space 6l is for the recep# tion of one of the milling cutters 50. Each of these milling cutters is provided with a key slot and the shaft is provided with a longitudinal key 63 extending substantially all the way across from bearing to bearing. This key projects into the key slot and the perforation 62 is large enough to permit it to rotate thereinY without touching its edges.

. lt will be seen, therefore,` that the carriages i ea can be moved along their supporting bars 53 to any. desired position. At all points in which they are in operative location above they type they will be positively rotated by the arbor 15.

On each end of each carriage is a pivoted.

to throw back the lever 64 from the bar 53 when released by the cam 66. Y

The central space 6l is formed by notching out the main body of the carriage and the cutter is held in position, in the form shown, by a detachable plate 69 secured over this notchat one side.

Located at the back of it is a.,

Located at the Vrear of thecutter isa breach 70. This is secured to the carriage in alignment with the cutter centrally throughout most of its height but at the bottom is widened out as shown at 7l. The passage of the work under the cutter will result in providing a groove of uniform thicknessin the work and the breach 7l widens it out at the bottom slightly.. l'n this way an undercut groove is provided as indicated in Fig. l1. Y Y

The grooves are iilled by inserting brass strips or rules 72 in them. These have one or more edges 73 for printing single or double column marks. They also have widened bottoms at 74 fitting in the Vgrooves produced as above described. On account of this shape the rules cannot be dislodged readily and, in fact, cannot be dislodged at all except by longitudinal motion.

It will be seen that any desired number of these carriages can be employed and that they can be moved on the bars 53 readily and spaced at any desired distance apart, which will be shown on the scales., Their opposite ends can be spaced alike very easily by observing the scale. The mechanism shownwill result in producing any desired number of undercut grooves throughout the block of slugs or lines of type carried by the frame. Y

Another feature of the invention, which is of importance in practical use, is that if the machine is kept running it will carry the carriage to one end until the racks 36 move out of mesh with the gears 33 and 35 and no damage will be done ifthe rest of the machine continues to run. Furthermore, by throwing out the clutch 27 the operator can move the carriage back'and forth by hand along its ways. This is a matter of convenience to the operator. Y

In o} 3eration,^the type, whether it is for printing characters or blanks, is set Vup in the frame as it will be needed for the printing operation just as it would be in the press. The cutter carriages are spaced the proper distances apart to provide the grooves in the right places and all the handles 67 set to hold the levers 64 in position to` keep the carriages properly located. The

Lac/aaai cording` to the convenience or the operator, but the handle 2O is kept in position to adjust the clutch rIhe frame l0 at this time is on the table 3T and the operator simply moves it up toward the arbor 15 until the racks 36 engage at their forward ends with the gears 33 and 35. Then he pushes in the handle 29 and the carriage is moved by power-throughout the length of the machine in one direction to produce the desired grooves in the type. The operator then disconnects the clutch and draws the table back by hand and then takes out the type and replaces it by a new set.
