SUSPENSION-DESKJ SPECIFICATION forming part of Letters Patent N 0. 575,269, dated January 12, 1897. Application filed March 21,1896. Serial No. 584,230. (No model.)

To all whom it may concern:

Be it known that we, JUSTIN E. PAGE, a resident of Independence, inthe county of Jackson, and MILES A. STAFFORD, a resident 5 of Springfield, in the county of Greene, State of Missouri, citizens ofthe United States, have invented certain new and useful Improvements in Suspension-Desks; and we do declare the following to be a full, clear, and I exact description of the invention,'such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked there- I on, which form a part of this specification.

Figure 1 illustrates our invention in side elevation as applied to a'railroad-car, the desk being in position for reading. Fig. 2 is an enlarged View of the desk and its attachments in side elevation with the book-holder ex tended. Fig. 3 is a front view of the desk with its attachments and the receptacle therefor, its position in said receptacle when not in use being shown in dotted lines. Fig. 4 is a central longitudinal section through the desk and its attachments, the desk being shown in horizontal position and the bookholder out of use. Fig. 5 is an end View of the roller E, showing its ratchet and pawl de- 0 vices. Figs. 6 and 8 are detail views of the bracket I and its arm. Fig. 7 is a perspective view of the book-holder detached.

This invention has relation to suspension reading and writing desks; and it consists in 5 the novel construction and combination of parts, all as hereinafter described, and pointed out in the appended claims.

The invention,wl1ile well adapted for use in the home or oflice, is more especially designed 0 for use on railway-trains or on steam or other boats where the jar or motion is such that the operation of reading or writing is attended with great difficulty, if not rendered impossible; and to this end the invention is designed 5 to provide means whereby the desk may be suspended in such a manner that it will not be subjectto motion or jar of the car or boat. The invention is also designed to provide a convenient desk or book-holder of novel character.

In the accompanying drawings we have shown the invention as applied to a railway car, but its application to other vehicles or to the house will be readily understood.

In the drawings the letter A designates the 5 5 frame of the desk, which is preferably of 0b long rectangular form, which is shown as being constructed of a piece of heavy wire or of rods, although any suitable material may be employed.

B designates the table of the desk, which is shown as being secured within the said frame by means of lugs orloops b.

C designates a supporting-bail whose lateral arms are loosely connected to opposite sides of the desk at points a short distance above its center. The transverse arm of this bail has an upwardly projecting arm C, around which is placeda loose tubular-casing C the upper end of said arm 0 being connected to the casing C by means of a spring 0 which is seated upon a flange at the lower end of the casing. Connected to the upper end of said casing is a strong elastic cord D, whose upper end portion is attached to a spring-roller E, which is journaled in suitable bracket-bearings secured to the roof of the car. This roller is similar in its action to a shade-roller, but it is provided with a much stronger spring. The journals of this roller, or one of them, is usually provided with a ratchet-and-pawl device 6, whereby it may be prevented from rotating under the action of its spring, if desired.

F is an adj usting-bail the upper end portions of whose lateral arms are loosely connected to the transverse arm of the bail C and whose horizontal arms are arranged to slide back and forth in slots or guideways F at the upper lateral portions of the deskframe A. Said slots or guideways are each formed intermediately with downwardly offsets or notches f.

When the desk is to be suspended in horizontal or nearly horizontal position, as when 5 used for writing, the bail-arm F is engaged with these oifsets or notches, as in Fig. 4; but when the desk is to be inclined to support a book said bail is moved to the upper ends of the slots or guideways, as in Fig. 2.

- from sliding down or out.

G designates a paper-holding roll which is journaled in lugs g, which depend from the under side of the table B. One of said lugs is of spring character, in order that it may be spread laterally sufficiently to permit the roll G to be removed from its bearings when its paper is exhausted and a new roll slipped in place. The paper (indicated at 'P, Figs. 3 and 4) of this roll is led down along the under side of the table to the lower or front end thereof, thence up through a slot g and along the upper side of the table, upon which it may be held by an elastic guard g G is a hood or guard for the paper-roll, and which is slotted, as indicated at g to permit the paper to be drawn off the roll onto the table, as above. described. The paper can be readily drawn off from the roll as fast as it is required for use. Attached to the corner portions of the frame A at the under side are two diagonally-extending intercrossing elastic cords H, on which is placed a loose ring H.

I is an arm which is hinged to a bracket 1, rigidly secured to the lower portion of the side wall of the car between two adjacent seats. Said arm has a hook i at its outer end which is designed to engage the ring H, above described. \Vhen not in use, said arm hangs down against the side of the car. To prevent rattle, the inner end of the arm is slitted to form a spring-tongue i, which engages the pin or pivot of the joint. A stop 2' on said bracket prevents the arm from being raised above horizontal position.

K designates an extension book holder, which consists of a bail-shaped frame which is arranged to slide on the side arms of the frame A. The transverse arm of this frame is normally adjacent to and just below the lower transverse arm of the frame A, as shown in Figs. 2 and 4E.

The side arms of the frame K are each formed with a downward bend or depression. and with an adjacent upward bend 70. When the frame K is not in use, the bends 71; engage the rear side of the lower arm of the frame A and prevent the book-holding frame WVhen said frame is to be used, its lower or outer end is raised and drawn forward, the bends in passing the lower bar of the frame A, while the bends 713 are engaged with said bar. The lower arm of the frame K is then held in raised position, as shown in Fig. 2, and forms an abutment for the lower edge of the book. The frame K may, as shown, Figs. 2 and 4, have two of the bends 70 at each side, in order that said frame may be extended to different positions to suit different sizes of books.

At the upper end of the desk, above the table B, the desk may be provided with a receptacle L for postal cards or stamped envelops. When the desk is used in a public place, this receptacle may be provided with one of the well-known nickel-in-the-slot mechanisms, so that by the insertion of a coin of the proper denomination a postal card or stamped envelop may be obtained. Above this receptacle is a pocket M for cards, envelops, telegraph-blanks, or the like.

When not in use, the arm I is disengaged from the ring H, which allows the roller E to wind the cord D thereon, and raises the desk to the upper portion of the car. To receive the desk when in this position, a pocket or holder N is provided. This pocket or holder is placed between two of the hatracks P with which railway-cars are usually provided, and is loosely sleeved upon a rod P, which connects said racks. Attached to the pocket or holder is a spring N, whose tension is such as to normally hold the pocket or holder in its upward and backward position. Attached to the pocket or holder N is a projecting arm R, having at its outer end an eye or guide opening through which passes the cord D.

Whenthe desk is raised as above described, the pocket or holder N is pulled downward and forward with the hand, against the tension of the spring N, and the desk is placed therein. The spring N then throws it upwardly and backwardly.

If desired, the upper end of the cord D may be attached directly to the arm R and the spring-roller E be omitted.

When the invention is used in a house or office, the pocket or holder N may be dispensed with, since, being free from motion, the desk will hang safe from the spring-roller when the cord D is wound thereon.

\Vhen it is desired to use the device, it is drawn down and the hook-arm I is raised and engaged with the ring II, the adjusting-bail F is placed in the properposition for reading or writing, and the book-holder, if it is to be used, is properly adjusted.

Inasmuch as the upper or farther end of the desk-frame is liable to come into contact with the back of the car-seat immediately in front it is usually covered or upholstered, as indicated at S.

Inasmuch as the connections which suspend and steady the desk are of elastic character, both above and below, it is designed to be rendered entirely free from jar or vibrations, and by its use reading or writing can be carried on without difficulty. The arm 0 and casing (3 give the suspension devices sufficient rigidity to prevent the desk from tipping from side to side.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is
