consequently the form when locked up is very heavy. By means of my improved furniture I can greatly reduce the quantity and weight of such blank filling material, thus lightening the form and reducing the labor and expense involved in getting the form ready for use.

A valuable feature of my invention is the ease with which the printer can arrange a filling for substantial size of blank space without using material enough to completely cover said space. My invention also lends itself to the production of fillers to fit rectangular spaces of various dimensions, particularly with the 30 em dimensions of the usual full length linotype slug.

My invention consists in the provision of hollow frames made up of four slugs, one at each side and interlocked at their ends in a simple manner so that when locked in a form the frames will retain their rectangular shape.

These slugs are readily cast on a linotype machine by means of a slug mold such as disclosed in my U. S. Patent No. 1,260,828, issued March 26, 1918. Such cast slugs are usually cast the full length of themold, that is, 30 ems long. They are usually made hollow to lighten them. By means of a slight modification of the usual slug mold I can cast the improved furniture slugs of my present invention.

My invention will be more readily understood by reference to the accompanying drawings forming part of this specification and in which Fig. 1 is a top plan view of a square hollow blank filler made up of slugs made in accordance with my invention; Fig. Qis a bottom plan view of a rectangular hollow blank filler similarly made; Fig. 3 is a perspective view of one of the in'lproved furniture slugs;

Fig. {is a fragmentary,vertical, sectional. view on the line l4- of Fig. 1; and

F 5 is a. fragmentary, horizontal, sectional view on the line 55 of Fig. l.

In said drawings 10 illustrates one of my "improved slugs. As shown, it is rectangular in cross-section, the one shownbeing about half an inch wide, 30 ems long and turniture height, that is, low enough-not to print when used in a form.' Preferably, though not nece'ssarily, such a slug is'hollow,as shown, to make it lighter in weight than if it were solid, also for the purpose of using less metal in its production. One end 11. of the slug 10 is square and the opposite end 12 is cut away at one side torfo m avertical notch 13' having awidth longitudinally of the slug, equal to the width of the slug and half the depth of the slug transversely thereof. This provides I a half width projection 14 on the notched end of the slug. This permits the placement of the square end of a second slug in the notch, the two slugs arranged to form a right angle and with the outer side surface of the second slug flush with the outer end surface of the projection 14. Aseach slug has one end square and the other end notched, as described, four identical slugs, as shown in Fig. 1, can be arranged in the form of a hollow square and each slug is held against compressive force applied to the outer surfaces of the square frame. In other words, I have provided a filling of minimum. weight for its size and one which will properly withstand the pressure of locking up without being distorted. It will be seen that the several slugs forming the hollow square frame shown in Fig. 1 are identical and that each one is held against inward movement at one end by the square end of the adjacent slug and at the opposite end by the shoulder 15 formed 1 on the adjacent slug at that end by its notch As one end of each slug is square the slugs can be readily shortened by sawing ofi' portions of their square ends and a hollow filling of smaller dimensions made as well illustrated by Fig. 2.

In order to lighten the projections 1 1 they may each be provided with a vertical groove or notch 16 at their inner sides, but this notch does not affect the function of the slugs to serve as furniture or in the makin of the hollow frames for fitting large blanh spaces in printing forms.

As many modifications of my invention will readily suggest themselves to one skilled in the art, I do not limit or confine my invention to the specific details of construction herein shown and described.

I claim:

The herein described improvement in the printing art comprising hollow type metal bars adapted to be cast on a linotype machine and of full 30 ems length, each bar being substantially one-half inch thick on its face and of type furniture height, each bar formed with a notch at an end and flat at the oppo- L site end, the notch having a width longitudi nally of the bar equal to the Width of the bars and having a depth transversely of the bars equal to one-half the width of the bars, the

bars being such that any desired hollow rectangular type furniture structure less in either dimension than that produced by the association of four such bars can be produced by merely cutting off the unnotched ends of the bars by a straight transverse cut normal to the length; of the bars.

In testimony whereof, I have hereunto set my hand this 18th day of September, 1928. ASHTON G. STEVENSON.
