JACOB KIEFER, OF BRIDGEPORT, CONNECTICUT.

i SPECIFICATION forming part 'of Letters Patent No. 418,522, dated December 31, 1,889.

Appncaipn'filea July 9, '1889.

Be it known that'I, JACOB KIEFER, apc-itizen of the UnitedStates, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in vType-Vriter Cabinets; `and I do herebykdeclare 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 appertains to make andy use the same.

vM y invention has for its writer cabinet which` shall be simple and inexpensive to produce, durable, easily operated, dust-proof, and `adapted to any ofv the various machines now inI use. Various styles of these cabinets have heretofore been placed upon the market. So far as I am aware, however, the low-priced cabinets have not proved satisfactory in use, while the complicated mechanism and great expense of others have prevented them` from going into general use. I have aimed to produce a cabinet which will obj ect a typeoccupy but little space, in which the Vnumber of parts and the cost of production shall-be reduced to the minimum, which will stand which will not tilt the machine suiiciently toany reasonable amount of hard vusage, and

\ cause the slightest displacement of parts when moved to the closed position., v

vI/Vith these ends in View I have devised the novel Vconstruction of which the'following description, in .connection with the accompanying drawings, is a specification, numbers being usedto denote the several parts.

vFigure l is a perspective illustrating my invention as applied to a double desk, the

type-writer .cabinet beingin the open position and the typewriter-removed; and Figs.

2 and 3 are transverse sections of a desk illustrating my novel mechanism, respectively, in the closed and open positions, the position of the type-writer being indicated by dotted lines.

l denotes a desk, which may be of any ordinary or preferred construction, and single or double, as preferred, the only requirement being a compartment closed at the sides. This compartment I have denoted by 2. At the front.

of the compartment is a support or supports 3 for the table, which may or may not extend entirelyacross the front of the desk,it being quite sentira. 316,929. mamada.)

sufficient to give the table a irm'bearing at both edges, although the desk maybe considerably braced and strengthened by extending the support entirely across. The typewriter is carried by table 4, which is provided with holes 5 tol receive the legs. is hinged at'the back to an intermediate connection, which in turn is hinged in any suitclearly shown in Figs. 1 and 2. p

It will of course be apparent that hinged the-desk instead of 4the swing-board shown. `In practice, however, I preferably use a swingback of the compartment will be always ,closed whether the desk is Ain the open or closed position. I also in practice cover the under side of the joint between the table and drop-leaf" by astrip 7, of felt orleatheiytherelby making the compartment perfectly dustproof in the closed position. The upper face of the support over which the table slides is preferably rounded and coveredwith a strip S, of felt or leather.

The' operation of Amy invention will' be clearly understood from Figs. l and 2.' The type-writer `is of course placed near the forllifted to its open position, as in Fig. 3, the

i. e., the turning-point--so that it will be impossible forV it to move to the closed position unless it is intentionally moved-to that position, as in Fig. 2, by lifting of the table and pushing it back.

9` denotes stops, ordinarily'made of rubber, which limit the upward movement of the rear end of the table, thereby preventing the possibility of the table and type-writer tipping forward. y

In order to overcome the inertia of the machine, and to assist in raising the table with the machine thereon to the open position, as

10, which are coiled about stumps 1l, said stumps being rigidly secured to the walls of the compartment. springs bear against the back of the desk, and the forward ends are extended to form arms 12,Which are attached to the connection This tablev center of `gravity of the type-writer will be' The rear ends of-thesel able manner to the back of the desk, as is -leversmay be used to connect the table with board, as shown in the drawings, so that the ward edge of the table, andwhen the table is forward of the inner edge of-the support,Y y

the forward edgeV in Figs. .l and 3, I ordinarily provide springs 6, near its forward edge. I have shown the forward ends of the arms as connected to the drop-leaf by links 13, engaging eyes in the leaf. The tendency of the spring is to raise the table from the position shown in Fig. 2 to that shown in Fig. Vhen a type-writer is on the table, its weight of course acts to retain it in the position shown in Fig. 2; but as soon as the operator takes hold of the table and draws it forward the spring acts to raise the connection and the rear end of the table, at the saine time sliding the table forward over the support. lt will thus be seen that the Weight of the machine when thetable is drawn forward over the support acts to retain the parts in the open position, and that when the table is pushed backward and allowed to swing downward over the rear edge of the support the type-writer overcomes the power of the spring and retains it in that position.

14 denotes the cover, and 15 a folding leaf, which closes the front of the compartment when the cover is let down, as is clearly shown in Fig. 2.

1G denotes guides at the sides of the compartment at the front over which connection G passes in closing, and which y hold it in position, as clearly shown in Fig. 2, preventing it from being swung inward until the leaf has been raised above the guides.

It will of course be apparent that the details of construction may be varied within reasonable limits without departing from the principle of my invention.

1. A desk having a compartment with a support at the front, in combination with a table, and a swingboard hinged to the rear end of the table and to the back of the desk, so that the hack of the compartment will be closed whether the desk is in the open or closed position.

2. A desk having a compartment and a support at the front, in combination with a table adapted to carry a type-writer, and a swing-board hinged to the rear end of the table and to the back of the desk, said table being adapted to slide forward over the support, so that both table and type-writer will be supported thereby in the open position, and to move inward and swing down back of the support inthe closed position, substantially as shown and described.

3. A desk having a compartment with a support at the front, in combination with a table resting upon said support, an intermediate connection hinged to the back of the table and to the back of the desk, and a spring acting to raise the forward end of the connection and the rear end of the table, thereby moving the latter forward over the support to the open position.

4. ln a desk, the combination, with the table, the support upon which it rests, anda connection hinged to the table and to the desk, of springs secured to the desk above the connection and loosely attached thereto, so as to raise the connection upward, carrying the table with it and sliding the latter forward over the support.

In testimony whereof l affix my signatu re in presence of two Witnesses.

JACOB KIEFER.
