IMPROVEMENT IN SOAP-FRAMES.

Specification forming part of LettersPatent No. 178,394, dated June 6, 1876; application filed 1 October 16, 1875.

To all whom it may concern:

Be it known that I, DANIEL WHITAKER, of Boston Highlands, Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Soap-Frame, of which the following is a specification:

Figure 1 is a top view of my improved soapframe, partly in section, and part being broken away to show the construction. Fig. 2 is a side view of the same, partly in section, through the line atm, Fig. 1. Fig. 3 is a cross-section of the same, taken through the line 3 3 Fig. 2.

Similar letters of reference indicate corresponding parts.

The objectof this invention is to furnish to manufacturers a soap-frame which, although simple in construction, shall be adapted to be more conveniently set up and taken down, and its side and end plates or pieces more firmly connected or locked together, than others of its class.

To these ends the base of the frame is made in three parts, secured to each other by transverse screw bolts or rods, whereby. they are adapted to clamp the bottom edgesof the sides of the frame; secondly, the bottom edges of the end portions of the frame are adapted to enter grooves in the base of the frame, and are attached thereto by hooks and staples in such a manner as to permit their convenient detachment; thirdly, the end portions of the frame have clamping-bars attached, whereby they may be locked to the sides, in such a manner as to hold the ends vertical, and form a tight joint between them and the sides; and, lastly, the side portions of the frame are provided with truss-like braces, whereby they are .prevented from buckling, warping, 850.

The frame is mounted upon a small truck, A, for convenience in moving it from place to place. Bis the base of the frame, which is made in three parts or piecesa wide center piece and two narrow side pieceswhich are held together by two or more bolts, 0, which are passed throughfthem transversely, and have hand-nuts G screwed upon their ends. D are the side'iplates, which are made ofplateiron, and the lower edges of which are inserted between the parts of the base B, where they are clamped by the bolts 0. The upper edges employ them in practice, principally for the reason that they cover less of the surface of the side plates D, and the radiation of heat is hence facilitated, which is a matter of considerable practical importance in respect to the cooling and solidifying of the plastic mass contained in the frame. These truss-braces D are a material improvement upon the wooden and metal bars heretofore employed, since the former of these are liable to become warped or bent, besides being cumbrous and otherwise objectionable, while cast-metal barssuch, for example, as shown in Patent No. 63,898-'-have proved too heavy and expensive to meet with other than local adoption and use. My improved braces combine strength, lightness, and cheapuess in a high degree, and.have hence proved superior in practice.

The end edges of the side plates E are bent inward at right angles to overlap the end boards G, the lower ends of which are inserted in cross-grooves formed in the middle part of the base B. The inner edges of the lower ends of the end boards G are rounded off, as shown in Fig. 2, so that their upper ends may be swung outward and the boards removed without marrin g the block of soap; The end boards G are held down by hooks H, attached to their lower parts, and which hook into eyes or staples I, attached to the middle parts of the base B. The end boards G and the side plates D are drawn and clamped together by the bars J, which turn in keepers attached to the end boards G, and the ends of which are bent near- 1y at right angles, to overlap the end parts of the side plates D, to draw them snugly against the side edges of the end boards G, and hold them securely in place. The said bars likewise draw the end boards G firmly against the flanges of the side plates D, by reason of being secured by keepers, as above stated. The said end boards are thereby held vertical, and

a tight joint formed between them and the' to each other by bolts and nuts 0 c, to adapt them to serve as clamps for securing the lower edges of the side plates D, substantially as herein shown and described.

2. The end boards G, having their lower ends rounded off upon the inner edge, and secured in cross-grooves in the middle part of described.

the base B by hooks H andeyes or staples I,

substantially as herein shown and described.

' 3. The combination, with the end boards G and side plates D, having inward flanges formed on their ends, of the clamp-bars J, the same being attached to said end boards by -means of 'ke'epers, as shown and described.

4. The combination, with side plates D, of metal braces or trusses E, riveted thereto at their ends, the blocks or filling F, and screwbolts, having their heads countersunk on the inner side of said plates, all as shown, and
