LEAD AND RULE HOLDER.

SPECIFICATION forming part of Letters Patent No. 383,962, dated June 5, 1888.

Application filed January 28, 1887. Serial No. 225,780.

To aZZ whomit may concern.-

Be it known that l, A. AUGUSTUS LOW, a citizen of the United States, residing in the city of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Lead and Rule Holders for Oompositors Use, of which the following is a'speeifieation sufiicient to enable others skilled in the art to which the invention appertains to make and use the same.

My invention relates to the class of rule and lead holding and presenting compartments heretofore originated by me, and for which I have obtained Letters Patent No. 356,845, dated February 1, 1887, in which the lowest leads or rules in a line'or column are successively removed through lateral openings at the frontor delivery ends of the compartments, the descent of the line or column of leads or rules being rendered automatic by reason of the inclination imparted thereto by various means heretofore set forth in said prior applications.

My present improvements relate, generally, to the features of special construction of parts herein shown and described, among the more important of which is the peculiar formation of the front edges of both the right and left hand side walls of the compartment, whereby, without resort to any, preparatory adjustment, as has been necessary heretofore, the operator may readily remove one, two, or three leads or rules, as he may elect. This is an advantage of considerable importance, especially in connection with the composition of job or other matter of a mixed nature, where variable numbers of leads or rules are required from time to time.

' This result. is effected, essentially, by forming the front edge of the right-hand side at an inclination which is steeper than the inclination imparted to the leads or rules, so that at the (NomodclJ the middle of the length of the leads or rules only two leads or rules will be started, and if the pressure is applied at the upper end only a single lead or rule will be severed from the line. i

In order to gage and render definite the respective positions at which the prescribed number of leads or rules may be removed, the front edge of the left-hand-side wall is formed upon the same general angle as that of the corresponding edge of the right-handside wall, but with offsets respectively corresponding to the thickness of one, two, and three leads or rules. Thus upon the left-hand side only the edge of the upper portion of one lead or rule is exposed, while the middle portions of two are exposed midway, and the lower portions of three are exposed below. Substantially the same result may be attained by making the front edge of the lel'thandside wall parallel 'with that of the right; but I prefer the use of the offsets mentioned as affording a means of 7 more readily locating the required position either to sight or touch.

The front edges of the side walls are beveled to facilitate the removal of the lowest leads or rules, as hereinafter described, For instance, the distance between the front end rests and the inner side of the right-hand wall is thus rendered slightly greater than the distance between the said front end rests and the extreme edge of the outer surface of the said wall, so that any slight variation in the thickness or inclination of the lowest leads or rules will be compensated for by such interior bevel.

Another notable feature of my invention consists in providing for the regulation or adjustment of the inclination of the leads orrules within the compartment by means of a mov able end linebearing-surfiice hinged to the upper part of the slug or follower, and resting 5 against an adjustable screw passing longitudinally through the body of the slug. By this means the inclination of the leads or rules may be adjusted with accuracy with relation to the fixed front edges of the side walls and varia- IOO tions in size or thicknesses thereby be compensated for.

In this connection my invention also includes the forming of the lower front end line support of a screw countersunk or inclosed in the forward part of the floor of the com sufficiently above the upper surface of the floor to act as an adjustable stop or rest for the heel of the lowest lead or rule in a line.

In my present construction the front end of the cover, which acts as the upper end linesupport, is hinged to a rear portion, which latter overlaps the side walls upon either side. The rear wall of the compartmentis also hinged so as to swing backward and constitute an extension of the floor of the compartment upon which the end line support or follower may be run out, when desired, in order to give access to the compartmeht'TrOm the rear, as

for purposes of filling, &c. This back or extension is formed with a shallow groove corresponding in width to that of the antifriction roller in the follower, and with a depression into which thelowerpart of the periphery of said rollerdrops when theslugis withdrawn to the proper extent, both the groove and the recess being employed for the purpose of stead y ing and retaining the said follower in position.

In the accompanying drawings, Figure l is an elevation of the right-hand side of my improved lead and rule-holding compartment; Fig. 2, an elevation of theleft-hand-side front end of the same; Fig. 3, a front end elevation; Fig. 4, a transverse section upon plane of line as m, Fig. 1; Fig. 5, a top view of the compartment, the cover being removed and the back lowered; Fig. 6, a longitudinal section of the compartment, showing the back lowered and the position ofthe rearend line-supportthereon in dotted lines. Fig. 7 is a longitudinal section of the front end of the compartment and the rear end line-support, the parts being inclined as in use; Fig. 8, an isometrical perspective of the front end of the compartment, and Fig. 9 a diagram showing the relative shapes of the front edges of the right and left hand side walls. Fig. 10is a longitudinal sec tion through the holder upon a plane parallel to the floor.

The holder consists of the usual elongated compartment, A, which in use is inclined at a suitable angle by being placed upon an inclined rest or seat, as in my last application, or by resort to any of the means heretofore described by me. The cover is formed with the flaps I) b, which overlap the upper side walls of the compartment; and it is made in two sections, the main portion 13 being retained upon the compartment by the engagement of its interior of the grooves b b with the exteriorof the heads a a upon the side walls, while the front section, B is hinged to the rear section, B, in such manner that it may be swung upward and back, so as to give access to the forward end of the compartment when re-, quired. The front section of the cover B is represented as raised by the dotted lines in Fig. 1. Its lower front edge, I)", when lowcred, rests against the upper end of the last lead or rule in the line, and is shaped substantially as shown in Figs. 3 and 8.

Thelower front end line-rest, 0, consists of partment, the head of which screw projects the perimeter of the head of the screw 0, which engages with a female screw-thread, 0', formed in the end of the channel floor or spine, the extreme front end of the latter being formed with the recess 0 within which the main portion of the screw-head G is inclosed. It will be seen that the floor of the channel is con tinued upon both sides of the slot or recess a", so as to afford support to theheels of the lowest types when the screw is adjusted outward. By thus in closing the screw it is also protected against accidental interference when adjusted in a prescribed manner. The rear end of the line of leads or rules is supported within the compartment, as heretofore, by a follower, D, which is provided with an anti-friction roller, d, similar to the manner provided for in my last application for patent; but instead of the front line end bearing-surface, (1, being permanent in inclination, as heretofore, I in the present case make it in the form ofa plate, d, which is hinged at the top of the follower- D, and extends downward in front thereof. The inclination of the bearing-plate d is increased or diminished as required by means of a screw, d passing longitudinally through the body of the follower and impinging against its' under side, as will be readily understood by reference to Fig. 7.

The degree of inclination to be imparted to the leads or rules may thus be regulated with accuracy, and this feature is of especial importance in view of the method herein employed by me in effecting the simultaneous removal of two or three'leads or rules, as may be required. To render possible the latter result without resorting to special adjustments of the lower side walls or bearings, as heretofore, I form the front edge of the righthantlside wall at a steeper inclination than that at which the leads or rules are to be controlled. The result of this, as illustrated in Fig. 1, is that when the lower end line-rest, O, is properly adjusted the lowest lead or rule will be entirely exposed upon the right-hand side, while the greater portion of the one next succeeding and only the lower portion of the third will extend beyond the front edge of the said righthandside wall.

'[tis obvious that if the thumb or finger be pressed against the left-hand edges of the lowest rules at or near their upper ends only the first orlowest lead or rule will be started toward'the right, since the upper front edge of the right-hand-side wall at that point will hold back the next succeeding leads or rules. In like manner, if the pressure he applied to the left-hand edges of the leads or rules midway of their length, the difference in inclination between the front edge of the right-handside wall and that of the leads or rules will permit of the starting forward of the lower portions of the two lowest leads or rules in the line, but will restrain the third. By applying a like pressure at or near the heels or the lower portions of the leads or rules the three lowest may be removed simultaneously.

In the case of the leads or rules thus started at or below the middle the heels thus firstprojecting beyond the front edge of the righthand wall insures the withdrawal of the middle and upper portions.

It is obvious thatin carrying outthis method of removing the leads or rules the front edge of the left-handside wall, a, may be made parallel to that of the right-hand wall above described; but in order to render more certain the respective operations of removing one, two, or three leads or rules, as required, I form the said front edge of the left-handside wall with three parallel edges, 1, 2, and 3, which respectively coincide with the inner side of the first, second, and third lowest leads or rules in the line when the latter are in position.

By reference to Figs. 2 and 9 the relative arrangement of the front edges of the right and left hand side walls will be readily understood, and as the positions of the three lowest leads or rules are indicated, it will be seen how the succeeding offsets 2 and 3 each expose an additional lead or rule to the action of the thumb or fingers upon the left-hand side.

The rear wall, E, of the compartment is hinged to the floor or spine in such manner that it may be swung down so as to constitute a rear extension of the floor, as shown in Figs. 5 and 6.

The inner surface of the wall or extension E is formed with a longitudinal groove, 6, which is of a width equal to the thickness of the anttfriction roller (I, mounted in the un der side ofthe follower D. This groove serves to maintain the alignment of the follower when the latter is run out upon the extension E. The extension E is also formed with a recess or depression, e, into which the roller (1 upon the follower D may be dropped in order to hold the follower when withdrawn, as indicated by dotted lines .in Fig. 6, against longitudinal. movement.

The front edges, a a of the side walls are preferably beveled, as indicated in Fig. 5, to facilitate the withdrawal of theleads or rules.
