SPECIFICATION forming part of Letters Patent No. 478,594, dated July 12, 1892.

Application filed April 24, i891. Serial No. 390,233'.` (No model.)

To a/ZZ whom it may con/cern: 1

Be it known that I, MAGNUs J. HAFeAR,a citizen ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Desks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Myinvention relates to office-desks, and its object is to provide new and improved means for carrying a swinging and sliding cabinet having pigeon-holes, book-racks, (ttc.

In-the accompanying drawings, 4Figure@ shows a frontrelevation of a desk. Fig. 2, is a front elevation of aportion of the same desk, showing the cabinet open, a portion of the desk being broken away to reveal someof the mechanism. Fig. 3 is a plan view of a portion of the desk with the cabinet open, a part of the top of the desk beingbroken away to show the internal construction. Fig. 4 is a bottom i plan view of thedesk with the cabinet open.

Fig. 5 is a transverse section on the' line 5 5, Fig. 2. Fig. 6 is a vertical section on the line 6 6, Fig. 4. Fig. 7 is a plan section on the line 7 7, Fig. 1. Figs. 8 to 13 are details of various portions of thev mechanism.

My invention consists of improvements in the mea-ns of carrying the cabinet, so as to adapt it for use in small and low-priced desks.

Iny the drawings, A represents a table-desk of ordinary form, having drawers in one of its upright portions C and a swingingcabinet B at the opposite end. The cabinetB is of such size as to fit within the standard of the desk and when closed forms the front and a portion of the side wall'of the standard, as more plainly shown in Fig. 7.

The cabinet B is supported by a caster K, carried by the pintle h', fixed in the plate h, which is attached to the floor of the cabinet. The caster K rides'upon the floor of the desk, which is provided with a metal plate L for that purpose. Sliding hinge-plates H and H are fitted between guide-rails a at the top and bottom, respectively, of the standard a. The cabinet B is hinged to the plate H by means ofthe pintlesf, g,'and h, iixed in the plate h at the bottom of the cabinet, and to the plate H by means of similar pintles f and g, fixed in the plate h .upon the top 'of the cabinet. Said pintles are located upon a 1ongitudinal line of the cabinet. Plates H and I-I are each provided with a quadrant slot d, crossing the inner rear corner `oroluarter of the plate, and also witha diagonal slot e between the front and outer corner of the plate and the curved slot d for the accommodation, respectively, of the pintles fand g. The distance between the inner'end of the slot e and i either end of the slot d or between the outer end ofthe slot e and the nearest point of the slot cl must not be less than the distance between theipintles f g.

In opening the cabinet B it is first drawn directly forward until the front ends of the plates'II and H come in contact with the front cross-bars of the standard a. The cabinet is then swung outwardly from the center of the desk, and by this operation the pintle g is carried from the inner to the outer end of the slot e and the pintle f is carried in the slot d to a point directly opposite the slot e.

As the cabinet is continued in its movement and the pintle f passes and recedes fromthe slot e the'pintleg lis .brought back tothe in- -n er end of the said slot.

The movement'of the cabinet, as abovedescribed, will cause' the caster K,-Which isv located forward'of the pintles f andy, to move in the form of a parabola, and I therefore locate a sloti of this form in the plate H` for Athe accommodation of the'pintle h'.

To insure the turning of the caster K, so that it will roll inthe direction in which the cabinet is moving, a longitudinal guide-flange Z is located upon the plate L adjacent to the line of movement of the caster K anda guidetlange j is placed upon the plate H adjacent to the inner side of the slott'.

For the purpose of preventing the cabinet from being easily displaced when open I provide devices for locking the plates H and H when they are brought to the forward end of the standard a and the cabinet is swung. The locking device for the plate H consists of a weighted pawl P, pivoted to the rearward end of said plate and adapted to engage inasuite able aperture in the guide-rail a. A strikerlplate p is fixed upon the inner end. ofthe cabinet, so as to` come in contact withthe weighted end of the paWl P when the cabinet is in line with the standard, thus throwing the pawl out of the aperture and unlocking the plate. The device for locking the plate H consists of a bolt N, carried in suitable eyelets fixed to the plate and adapt-ed to be thrownV into an aperture in one of the guides rails a. The bolt N is provided with a lateral lug n, having one of its edges beveled and extending across the inner end of thaslot A springO is secured to the plate I-I by the pino in such position as to engage the lug n, so as to throw the bolt outwardly. When the desk is inline with the standard a, thepintle f forces the i bolt N back and unlocks the plate Il. W'hen the cabinet, isv swirng, the bolt is rel-'eased andthe plate is locked. A caster-W is placed at the forward outer corner of the desk to support the. cabinet andy relieve the fric-tion. The innerr or rearward end of the cabinet is necessarily narrower than the forward end. Shoulderpieces b are placed' at the forward' end of the narrower part ot the cabinet, so as to abut. against thef side wall of the; standard' when: the cabinet is: closed, thereby preventing in a. measure lateral move-ment of the cabinet. Lateral movement of the cabine-t is entirely prevented by mea-nst of the hook o", attached to the standard a, so asl engage the socketR on the oufter'end ot` the front of the cabinet when the latter ifs closed.

I am aware that; al swinging cabin-et having projecting arms carrying hinge-.pins hasbeenl used with fixed plates, havingv segmental and s diagonal slots', and I do. not claim such construction.,
