.SPECIFICAIION forming part of Letters Patent No. 690,142, dated December 31, 1901.

Application filed September 8,1900. Serial No. 29,437. [No model.

To all whom, it may concern:

Be it known that 1. WILLIAM ll. GOLDING, a citizen of the United States, residing at Boston, in the county of Suffolk, State of Massachusetts, have invented certain new and usefullmprovements in Type-Cases, of which the following is a specification, reference being had therein to the accompanying drawlngs.

This invention has relation to type-cases; and its principal object is the provision of means which shall permit of contraction and expansion occasioned by either the natural seasoning of the wood, of which the bottom and other portions of the case are constructed, or by changes in atmospheric conditions, such as dampness and dryness, to which a typecase is subjected.

Another object of the invention is to so construct a case that in the retention of the bottom in the case the least number of nails possible are required.

A further object is to so construct the case that the bottom thereof may be formed in sections, thereby permitting expansion and contraction of individual portions of the bottom independently of other portions thereof, whereby undue warping and distorting strains upon the framework of the case are avoided.

It is well known that it is desirable a typecase should be constructed of material in as small dimensions in cross-section as permissible, in view of the comparatively excessive weight of material which the case is designed to contain. In attaining this object-to wit, lightness of structurethere naturally follows a greater liability of warping, and to overcome this tendency a construction of framework should be provided which will permit of the contraction and expansion of the bottom without undue pressure, strain, or distortion upon the framework.

Other objects and advantages of the invention will hereinafter appear in the following description, and the novel features thereof will be particularly pointed out in the appended claim.

Referring to the drawings, Figure 1 is a partial plan. Fig. 2 is a vertical cross-section on the line 2 2 of Fig. 1. Fig. 3 is a perspective of the central rail of the framework. Figs. 4. and 5 are modifications of the central rail. Fig. 6 is a bottom plan of a complete typecase constructed in accordance with my invention; and Fig. 7 is a vertical section through the rear rail, bottom, and securing device.

Like letters of reference indicate like parts throughout the several figures ofthe drawings.

A represents the front rail; B B, the side rails; C, the rear rail; D, the central rail, and E the bottom of the type-case. The side and central rails B B D, respectively, are inset, as at B D and doweled, as at B 13 and D, into the inner face of the front rail, while the back or rear rail is flush-jointed and doweled into the side rails B, as shown at O by dotted lines. (See Fig. 6.) The bottom is preferably formed of two sections E E, and the main object of the invention is to connect said bottom with the framework proper of the case in such a manner as to permit of contraction and expansion of either the bottom or the framework without distorting the case and so as to at the same time maintain the necessary strength to support a heavy load and the necessary closeness of all joints existing between the frame and the bottom to prevent admixture of the type within the several partitions of the case. These objects are accomplished by means of the following construction: Each of the rails of the case, with the exception of the rear rail, is provided with a groove D as shown clearly in Fig. 3 and as indicated by dotted lines in each of the rails shown in Fig. 6, and in these grooves the front and side edges of the bottom or of each section thereof rest, while the rear edge or end of the bottom rests beneath and is secured to the under face of the rear rail, the upper surface of which is flush with the upper wall of the said grooves. By this construction a single nail F or otheranalogous securing means is all that is required to retain the bottom within the frame.

Now it will be noted that freedom of movement exists within the bottom or bottom-sections in all directions except at its rear end, where it is nailed to the rear rail. As contraction and expansion occur across the grain of the wood of which the bottom is composed tween the edge of the bottom or a section thereof and the inner wall of the groove in which said edge rests.

In constructing a frame embodying my invention the central rail D is preferably formed of one piece of material grooved near its bottom upon opposite sides, forming a neck D with a head D This rail may be cheaply made'by existing forms of Woodworking machinery in long lengths, cut off to the desired length for a type-case, and bored at its ends for the reception of the dowels D. It is apparent that the central rail D may be formed with the neck B only, and a head D formed of a separate simple strip, may be secured to the neck by nails D or other securing devices, or the neck D and head I) may be formed integral and secured in like manner to the main portion of the central rail, as shown in Fig. 5. Various other subordinate deviations in the construction of the central rail itself and in the manner of connecting the same with the front and rear rails and of connecting the front and rear rails may be substituted without a material variation from my invention as disclosed herein. Furthermore, as is usual, a lining of paper or other suitable material may be secured to the upper surface of the bottom or bottom-sections before it is applied to the case.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

A type-case comprising side, front and central rails, each provided with a groove near its bottom ,a grooveless rear rail having its bottom flush with the upper walls of the grooves of the adjacent rails, wooden bottom-sections of less dimension than the distance between the vertical walls of opposing grooves in the side rails, and a securing device passing through each bottom-section and into said grooveless rail for securing the bottom against movement laterally of the IGEtll'tll; substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.

WILLIAM H. GOLDING.
