APPARATUS FOR PRODUCING RULES ON LINOTYPE-SLUGS.

Application filed February 7, 1911.

To all whom it may concern.

Be it known that I, EVERETT M. Low, a citizen of the United States, and a resident of the borough of Brooklyn, in the c1ty of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Apparatus for Producing Rules on Linotype-Slugs, set forth in the following specification.

My invention relates to a device for producing the rule which prints the vertical lines in tabular work, though the same may be employed for various kinds of rule. Several methods have been in use for producing the vertical rule on linotype slugs necessary for tabular work, but they have proven only partially satisfactory, owing to the 1naccuracy of the work, the cost and labor 1n carrying out the methods, and the delicate and unsatisfactory character of the rule.

My invention covers a novel and simple machine whereby the chase may be placed in a holding frame and the large rule planed down to make the several sections thereof, and form a complete, even rule. This machine or apparatus permits corrections to be made in the slugs, either before or after planing the rule.

In the drawings forming a part of this application,

Figure 1 is a plan view of an apparatus embodying one branch of my invention,

Fig. 2 is a vertical section thereof, taken on the line 22 of Fig. 1,

Fig. 3 is a. side elevation thereof,

Fig. 1 is a cross section taken on the llne 4 at of Fig. 2,

Fig. 5 is a similar view taken on the line 55 of Fig. 2,

Fig. 6 is a section taken on the line 66 of Fig. 2, I

Fig. 7 is an elevation of a slug, showing the method of planing the rule,

Fig. 8 is a plan of Fig. 7,

Fig. 9 is an elevation of the planing knives.

In order to carry out a simple method I preferably employ the apparatus shown in the drawings, which is constructed and operated as follows;

The slugs as they are taken from the linotype machine are locked in the chase 12 in the usual way, and I have shown the slugs locked in the chase by means of furniture Specification of Letters Patent.

Patented Aug. 14:, 1917. Serial No. 607,025.

13, between which are forced the wedge blocks 14, but the slugs may be locked in the chase in any of the well known ways. The slugs can be thus locked in the chase before any corrections are made, and before the proof is struck off the chase can be mounted in my improved apparatus, for the purpose of planing the rule. The corrections on the slugs chase is mounted in my apparatus, however, but as my invention permits corrections being made in the slug without interfering with the previous planing of the rule, I will describe my device as used when the chase is placed therein before the corrections are made and I will describe how the rule is planed after corrections have been made, in a case where the rule was planed before the corrections had been made.v

The chase may be of the usual construction, except that I prefer to form the dovetail slots 15 on each side rail, for looking with the frame in which the chase is mounted for the planing operation. I have provided a frame or holding structure 16, in which the chase is mounted and held during the planing operation, and this frame is preferably rectangular in shape and provided with a depression 17 for the chase of sufficient size to allow the chase to be moved along the pocket and clamped in various positions, according to the location of the rule on the slugs in relation to the planing device, which latter I have arranged to operate at a definite position. I have provided a projecting rib 18, in the frame 16, which extends into the pocket 17 and this rib is received by one of the slots 15 on one side of the chase. Lying against the opposite side of the chase I have provided a locking bar 19, which has a rib 20, which is received by the slot 15 on the other side of the chase, similar to the rib 18 on the frame; and this locking bar is forced against the chase by means of the screws 21 which pass through one side of the frame 16 and against the locking bar. I provide a plate 22, which is screwed on the frame 16, over the locking bar, and the purpose of which is to hold the locking bar and the chase from displacement in the frame. The frame is thus firmly and accurately held in the frame 16, and

whenever it is to be moved along the pocket 17, the screws 21 are loosened and the chase can be made before the is moved longitudinally along the pocket to bring the rule in proper relation to the planing knives.

The slugs are disposed longitudinally when placed in the chase and they are therefore longitudinally disposed as regards the frame 16. This causes the rule to lie in a direction transverse of the frame 16. There may be one or more rules on the slugs, composed of the individual sections on each slug there being a plurality of rules shown in Fig. 1. lVhen the chase is mounted in the frame the rules will be in the condition shown in the right of Fig. 7, that is, they will be in their first condition, as they were originally cast the individual sections of the rule being of greater proportions than the finnished rule is to be.

Above the chase I have provided a stationary bar 24, which serves as a support for a gage 25 and also as a guide for the block -which carries the planing knives. The gage 25 straddles the bar 21 and is adapted to be moved along the latter and its pointer 26 is used to indicate the proper position at which the chase is to be placed in order to bring the rule of the slugs in proper position with relation to the planing knives; and when once the chaseis positioned with the use of the gage, the latter may be removed from the bar 21 or moved along out of the way of the planing knives, when the planing operation may be performed on the rule which has been brought into proper relation with the planing device.

I have provided a support for the planing device which consists of a standard 2?, bolted to the base or frame, and on the top of this standard is a cross beam 28, extending laterally across and above the frame 16, the web 29, serving to strengthen the beam 28. Upon this supporting structure I have mounted the movable arm for supporting and guiding the planing block, and the fulcrum block therefor, as well as other elements. On one end of the beam 28 and preferably beyond the frame 16, I have provided a block or frame 30, in which the fulcrum of a movable arm is mounted and I have shown this block or frame as cast integral with the beam 28, though it may be otherwise formed. There is a swinging arm 31 which carries and guides the planing block and this is mounted to lie in the direction of the planing, which will generally be transverse of the chase, and this arm fulcrums from the stud 32 which is fastened in an adjustable journal block 36. The block Orframe 30, comprises the upright web 33, and the upper and lower longitudinal webs 3a and 35, forming three sides of a pocket for the journal block 36, the other side being closed by a removable plate 37, which is bolted to the webs 3st and to inclose the block 36. The block 30 forms a pocket for the journal block larger its vertical dimensions so that the journal block may be adjusted vertically. The journal block 36 is held in position by means of the adjustable screws 38, at the top and bottom, which determine the position of the former, and by means of these screws the block 36 may be raised or lowered and the fulcrum of the arm 31 thus raised or lowered to move the cutting knives toward or from the plane of the rule of the slugs. This may be necessary in order to adjust the knives with relation to the rule, when the knives have become shortened by sharpening.

The arm 31 thus takes its fulcrum from tle stud 32 and it moves in the arc of a circle which is perpendicular to the plane of the slugs. On the opposite or free end of the beam 23 I have provided means for controlling the movement of the arm 31 by which the movement is limited. On the end of the beam 28 there is a pocketformed by the upright web 39 and the horizontal webs 10 and a1, the opposite side being closed by aremovable plate 1-2; and in this pocket moves a block 4:3, which is mounted on the free end of the arm 31. There are limiting screws 4:1 and 45, extending through the webs 10 and -11 respectively, and the extent of movement of the arm 31 is determined by the adjustment of these screws. Spring 16, interposed between the web 11 and the block 1-3, and surrounding the screw 15, tends to force the arm 31 upwardly as far as the position of the screw as will permit.

The planing block moves along the arm 31 during the planing operation and is preferably constructed as follows: i

There is a block 18 movable along the arm 31, and it is held on the arm 31 by the flanges 4:9 and 50 which partially surround the arm 31 and cause the block to be guided by the latter. The block is provided with a handle by which the block is moved across thearm forthe planing operation. The lower portion of-the block is provided with downwardly extending plates 51, 52, which straddle the bar 2% and thereby guide the block and prevent it tilting, making the work of the cutting: knives accurate. On the block as is mounted a. rocking planer which fulcrums at upon a stud secured to the block as and to the forward portion of this planer I have secured the planing knives. I have shown the planing knives 56, 57, and 58 bolted against the face of the planer 5 1, and I have ar'anged them one behind the other, the particular.relative arrangement being optional. I have shown the front knife 58, however, as having the flat cutting edge and adapted to plane the top of the rule down to the plane of the type faces and the top of all. the component sections of the rule. of the several slugs to than the latter in a common line; while the knife blades 56 and 57 are provided with angular cutting edges as clearly shown in Fig. 9, one being adapted to cut the right side of the top of the rule and the other the left, so that the combined cutting action of the three knives will plane the rule down to its ultimate pro-- portions and position. The knife for cutting the top surface may be dispensed with, but I prefer to employ the same.

The operation of my device when constructed in exact accordance with the drawings will be as follows:

The slugs having been cast with enlarged sections of the rule they are locked in the chase and though the rule on the several slugs may not perfectly aline, there will not be a great difference in alinement, though enough to make the printing from a rule in this condition irregular. The chase is then placed in the pocket 17 of the frame 16, and is moved therealong until the rule which is to be first planed is in proper relation to the knives. This position will be determined by comparing the rule with the gage. lVhile positioning the chase, the arm 31 is swung upwardly, by loosening the screw 4: 1, to move the knives above the face of the type. properly positioned for the planing operation, the screws 21 are tightened to force the locking bar 19 against the chase to hold the latter firmly in place.

The planing begins from the left side in v Figs. 1 and 2 and instead of planing the whole cut in one operation I prefer to plane the rule to a slight extent and then return and on the next movement forward cut deeper, etc., until the planer is finally moved down to cut to the desired depth. The arm 31, which fulcrums from the stud 32, is elevated at its free end by turning the screw 44, when the spring 46 will hold up the end of the arm in contact with the screw 1 1, and the lower screw 45 is so adjusted that it will stop the downward movement of arm 31 when the knives have completed the desired depth of cut. The handle 53 is clutched and the planer is moved along the arm, which will cause the knives to cut the rule in line therewith, in the manner shown in the left of Fig. 7; and after a partial cutting of the rule the planer is returned for a new stroke. lVhen the planer is thus returning the knife head 54 may swing on the stud 55 to prevent any injury to the rule during the return movement. Previous to another stroke with the planer the screw 44 is turned down, which will lower the arm 31 and also the planer, to cut deeper on the rule and these operations are repeated until the arm 31 strikes the screw 45, when the rule will have been cut to the proper line and itwill then appear as in the left in Fig. 7. If corrections to the When the chase has been composition were made previous to the planing operation the chase can now be removed and used for printing. But if corrections are to be made after the planing then the steps will be as follows:

The slugs which contain defects are marked for correction and if the form is in the press it is removed and the slugs containing errors are removed from the form and new slugs are cast in the linotype machine to take their place and these new slugs are made as previously described, with the rule sections cast on them. The corrected slugs and the ones which were removed from the form are locked in the chase and are set in my apparatus. To locate the chase for the planing, the chase is moved to a position which will bring the rule of the old slugs to the gage and the chase is then clamped. The planing then takes place as before and as the rule of the corrected slugs is planed in accordance with the rule of the slugs which they are to replace, the rule will accord with that of the slugs in the form, when the new slugs are locked in the form.

The object of locating the knives at different positions relative to the length of the rule to be operated on, is to avoid the collecting of the chips and their clogging the work and thus marring the face of the rule. It is necessary to have any two of the knives that act on contiguous surfaces of the rule spaced from each other relative to their direction of movement. The knives which operate on non-contiguous surfaces, where three knives are used, may be in the same transverse line, provided the other is in ad vance or in the rear thereof, but preferably they are all arranged in advance of each other, as shown in the drawing.

It will be apparent that under my invention a very durable rule is formed, and any irregularity which is present in the rule when locked up in the chase is overcome by the planing operation and a clear printing, regular rule, equal in height to the face of the type, is formed. Also the corrections may be made after the planing of the rule, without injuring, or changing the condition of, the planed rule.

Various changes may be made without departing from the scope of the claims.
