SPECIFICATION forming part of Letters Patent No. 333,760, dated January 5, 1886.
Serial No. 173,834. (No model.)
T @ZZ whom it 711/01/ concern:
Be itknown that I, CHRIS LARSON, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvementsin Desks, of which thefollowing is a specification, reference being had to the drawings accompanying the same,and forming a part thereof.
My invention relates to an improvement in desks of that kind in which the pigeonholes upon one or both sides can be drawn forward and then swung around at right angles, so as to stand in a line, or nearly so, with the front of the desk; and the present invention is an improvement upon the invention made by lne and described and set out in Letters Patent No. 278,152, dated May 22, 1883, and granted me;
and my invention consists in the combi- 2O nation of the bottom of the desk, having suitable grooves formed therein, with the bottom of the pigeon-holes provided with studs or projections which catch in the grooves, guiding the pigeon-holes, so as to allow them to first be drawn forward, and then swung around at right angles, as is hereinafter more fully described and claimed.
The weight of the pigeon-holes need not necessarily rest upon the stud or projection herein O described; but instead thereof casters may be placed upon the bottoni of said pigeon-holes, rolling upon the upper surface of the bottom of the desk, in the ordinary manner in which such casters are used.
By the constructionherein specifically described,frictionthe main obstacle to be overcome in devices of this nature-is reduced in a very great measure, the construction simplified, and the certainty of a uniform' characo ter in the operation of the device secured in a much greater degree than in any of the devices of this kind heretofore in use.
Figure l is a side elevation of one end of a desk embodying my invention. Fig. 2 is a plan View of the bottom of the desk, showing the grooves. Fig. 3 is a view of the bottom of the pigeonholes, having the studs or projections on the under side thereof indicated by dotted circles. Fig. 4 is a plan view of the two parts, 5o showing the bottom of the pigeon-holes and the bottom of the 'desk in their relative positions when the pigeon-holes are closed. Fig.
5 is a similar view showing the same parts in their relative positions when the pigeon-holes are drawn outward and turned around at right angles.
Like letters refer to like parts throughout the several views.
A is the bottom of the desk.
B is a long curved groove in the top of bot- 6o tom A. Y
C and D are short curved grooves passing outward from groove B, also in the bottom of the desk A. These grooves may be formed in a casting which is inserted in the top of the bottom A; or said grooves may be cut in said bottom and lined with metal.
B', C', and D are studs or projections projecting from the under side of the bottom of the pigeon-holes.
E is the bottom of the pigeon-holes.
When the pigeon-holes are closed, pins C', D', and B are all in groove B, as is illustrated in Fig. 4. Then the pigeon-holes are drawn out, pins B', C', and D all follow or are guided 75 by curve B, andthe pigeon-holes may be drawn out until pin B' is at the end of curved groove B, and when in this position studs C and D' are respectively opposite to curved groovesC and D from said curved groove B, and the pigcon-holes may then be turned or swung around upon pin or stud B', studs or pins C and D entering into and being guided by curved grooves C and D, respectively, and the pigeonholes will thus assume the position illustrated in Fig. 5, the studs or projections B', D', and C' being in the position there indicated.
Curved groove B, cast in iron or other metal, may be placed in the frame-work of the desk over the top of the pigeon-holes, and a 9G stud or prQjection,B',is placed in the top of the pigeon-holes and projecting above said top, enteringinto said lastfnamed curved groove B.
The groove B, placed, as last described, in the frame-work of the desk over the pigeonholes, is the precise duplicate of groove B as ill nstrated in Fig. 2, and is placed immediately or vertically above said groove B. Pin B', placed in the top of the pigeon-holes, is placed over pin B in or stud or projection as said B.
The casters, hereinbefore referred to, set in illustrated in Fig. 3, and is a like 10o that the said pins must also be placed at threeV points in the arc of the saine circle. Itis also evident that pin D', being the middle of the three points on said arc, serves no other or different purpose than the steadying of the pigeon-holes, guided by said pins in said arc; and, further, that the grooves C D are also true arcs ofa circle having a radius equal to the 2o distance from the point of divergence of said grooves G D from the end of groove B, around which projections C D rotate when said pigeon-holes are turned upon projection B', the said groove D and pin D serving thus only to steady, as above stated, the said pigeon-holes, and may therefore be omitted, if desired, Without materially altering my invention.
Having thus described my invention, I claim- In a desk, the bottom having the curved groove B and the two concentric grooves C D, connecting With the same on the opter side thereof, in combination with pigeon-hole case E provided with studs fitting into said grooves, substantially as set forth.
CHRIS LARSON.
