1'0 (Libra/tom, it may concern:

Be it known that 1, JOHN GRAMELSPACHER, a citizen of the United States, residing at Jasper, in the county of Dubois and State of Indiana, have invented a new and useful Combined Desk and Type Writer Cabinet, of which the following is a specification.

This invention relates to combined desks and type-writer'cabinets; and the object of the invention is to produce an article of office furniture of this class which shall be simple in construction and not liable to get out of' working order, in-wi1ich the type-writer when not in use shall be held in a position where it will not obstruct the use of the desk for ordinarywritingpurposes;"toprovidean'improved and simple mechanism 'for holding the typewriter table at any desired elevation while in use and to provide for its convenient release when not in use, so thatit maybe restored; to the cabinet provided for its reception; to provide an improved construction ofa combined means for operating the lock whereby the type-writertable-is retained in position. when not in use and the mechanism whereby. the said table is supported while in use, and: to provide an improved means for locking the folding part of the fiat top of the desk in posi tion when used in conjunction with a roller top or curtain.

With these and other objects in view my invention consists in theimproved construction, arrangement, and combination of work.- ing parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings, Figure lis a perspective viewshowing a roller-top desk; equipped with my improved type-writer cabi. net, the type-writer table being shown ele-' vated into position for use. Fig. 2 is a bot--v tom plan view showing the type-writer cabinet and adjacent parts of the'desk, thetypewriter table being shown in the, position which it occupies when elevated for use. Fig. 3 is a vertical sectional view taken longitudinally through the type-writer cabinet and showing the table elevated, adjacent parts of the desk having also been shown. Fig. 4 is a front view of the device as seen in Fig. 3. Fig. 5 is a detailed view partly in section, showing the auxiliary locking device for locking the desk-fiapwhen the roller curtain ot' the desk to which-the device is applied is lowered. Fig. 6 is an enlarged sectional view showing the device for locking the type-writer table in. its lowered position.

Corresponding parts of the several figures are indicated by like characters of reference.

1 designates the desk-frame, which may be of any suitable well-known construction. In the drawings an ordinary roll-top desk has 'been shown,comprising'the outer sides 2 2 and the inner sides 3 3, said outer and inner sides forming receptacles ordrawers 4. The top is composed of sides 5 and'back 6 and is .providedwith the roller-curtain 7, all of which are of ordinary construction.

My improved type-writer cabinet is located between the inner desk sides 3 3, to which the side pieces .8 870i said cabinet are suitably secured. It will be understood, however, that these sidepieces might be omitted and the 1 when the latter is placed in the cabinet and which forms practically a dust-proofcover for the same. The bottom of the cabinet proper is formed by the swinging table 11, which is supported at each end by a pair of links 12, the upper ends of which are connectedpivotally with lugs or ears 13 upon the under side'of the top 14 of the cabinet, whichisarranged a short distance below the desk-top proper, andjthe lower ends of which have pivotal connection with similar ears or lugs 15, secured upon the upper side of the table 11. The rearmost pair of. links 12 are connected by means of stoutsprings 16 with the sides of the cabinet near the front edges of the same, the said springs serving in part to support the weight of the table. and the machine which is in practice to be placed thereon, so as to assist in lifting the weight thereof when being raised to an operative position and likewise to restrain its fall when being lowered out of the way.

The table proper, 11, is provided on its updesk. 'I have therefore provided an automatic locking device, which is necessary to the successful operation of this invention and which I shall now proceed to describe.

The hinged flap 43 of the desk-top is provided at or near its front edge with a depending transverse strip 47, in rear of which and closely adjacent to the edges of the folding flap 43 are pivoted bell-crank levers 48, the vertical arms of which are provided at their lower ends with beveled catches 49, adapted to engage recesses or sockets 50, which are formed for their reception in the inner sides of the side walls of the cabinet. These bellcrank levers may be pivoted directly to the rear side of the strip 47, or they may, as shown in the drawings, be mounted in lugs or ears 51, suitably secured to the under side of the folding desk-flap 43. Upon the rear side of the strip 47 are secured brackets 52, between which and the horizontal arms of the bell crank levers 48 springs 53 are interposed to force the said horizontal arms in an upward direction, thus throwing the catches at the lower ends of the vertical arms of said bellcrank levers normally out of engagement with the recesses or sockets 50. The brackets 52 are preferably socketed for the reception of the lower ends of the springs 53, as has been indicated in the detail view, Fig. 8 of the drawings, at 54, thus preventing said springs from being accidentally displaced. The desk-flap 43 is provided directly above the free ends of the horizontal arms or levers 48 with vertical perforations 55, in which are seated cylindrical slides 56, impinging upon the free ends of the horizontal arms of said levers. The said slides 56 are made of such a length that their upper ends shall normally be flush with the top of the desk-flap 43. Suitable means, such as transverse pins 57, engaging recesses 58 in the sides of the slides 56, may be employed to retain the latter in position in the perforations 55 and to prevent them from dropping out when the desk-flap 43 is being thrown open.

The bottom cleat 59 of the roller-curtain 46 of the desk-top is provided on its under side with downwardlyprojecting pins or dowels 60, which are so arranged as to register with the slides 56. When the roller-curtain is lowered for the purpose of closing the desk, the said pins 60 will impinge upon the upper ends of the slides 56, forcing the latter downwardly and causing them in turn to opcrate the bell-crank levers 48 against the tension of the springs 53, thus throwing the catches 49 at the lower ends of the vertical arms of said bell-crank levers into engagement with their recesses or sockets 50. At

the same time the ordinary desk-lock with which the roller-curtain is provided comes into engagement with its mortise or socket in the upper side and near the edge of the folding flap 43. The latter being now held securely by means of the catches 49 of the levers 48 engaging the sockets 50, the desk will ble in operative position at various eleva-' tions. In type-writer cabinets as ordinarily constructed the table may be raised to and supported at a single predetermined elevation only. It has therefore been necessary for the operator in a great many cases to adjust his or her seat to the proper height in order to be able to operate the type-writer conveniently and with the best results. I am of course aware that vertically-adjustable sup ports have been heretofore made and used; but I am not aware that a link-supported table forming the bottom of a cabinet when the latter is closed has been heretofore made in such a manner as to be capable of vertical adjustment in its operative position. Another and not unimportant advantage is the equipment of the table with an auxiliary table or slide which may be drawn forward, as shown in Fig. 3, thus enabling the operator to adjust the type-writer in the most convenient and comfortable position. The desk-room is usually so fully occupied that when a typewriter cabinet is I added to the desk the position of the operator is frequently uncomfortably cramped. This auxiliary table or slide enables the operator to move the type-writer forward or outward, so that ample room for the limbs will be had under the table.

It will be seen from the foregoing that my invention provides a type-writer cabinet which is capable of being applied to almost any desk of ordinary construction, whether it be provided with a roller-top or with the ordinary fiat top only. It is obvious that in the latter case the auxiliary locking device is dispensed with. I would also have it understood that I consider myself to be entitled to any modifications in the construction and arrangement of parts which may be resorted to without departing from the spirit of myinvention. Thus, for instance, the side walls ofthetype-writing cabinet need not be attached to the desk-walls 3 3, but may be located at a distance from the same, which may be found desirable when the latter are located at a considerable distance apart.

Having thus described my invention, I claim and desire to secure by Letters Patent of the Unit-ed States 1. In a device of the class specified, a cabinet having side walls, keepers carried bysaid side walls, an adjustable table adapted to su pport a type-writing machine, links for guiding the movement of said table, and lockingbolts disposed at opposite sides of the table at points near the front edge of the latter and adapted to engage said keepers, to thereby net having side walls, segmental ratchetsmounted upon said walls, a link-supported table forming the bottom of the cabinet when lowered and adapted for the support of a type-writing machine, and spring-actuated pawls carried by said table at a point near the front of the table and adapted to engage said ratchets to thereby afford a rigid'snpport for the table and the weight of the type-writing machine.
