ARM-REST.

SPECIFICATION forming part of Letters Patent No. 744,287, dated November 17, 1903.

Application {iled February 19. 1903. Serial No. 144,140. (No model.)

To all whom t may concern:

Be it known that I, ROYAL HINDS BRASEL, a citizen of the United States, residing at Muskogee, Creek Nation, Indian Territory, have invented a new and useful Arm-Rest, of which the following is a specication.

My invention is an improvement in armrests; and the object of the device is to produce a rest especially adapted for the use of writers using a surface gradually decreasing in height relative to the surface of the table or desk on which the Writing material is placed.

vThe device is adapted not only for use of express, money-order, and other clerks using pads of considerable thickness and which thickness decreases as the sheets are gradually used and torn from the pad, but can also be used by bookkeepers using heavy books,

which books are often made up of a great' many pages, and when writing adjacent the bottom of the page the hand cannot rest on the page, and the leaf is often too far above the desk on which the book rests to permit the hand to be steadied on the desk while writing.

The special object of my device, therefore, is to produce an arm-rest the upper surface of which will be approximately in the plane of the surface being written on.

In the accompanying drawings, Figure 1 is a perspective view showing my device in p0- sition for use. Fig. 2 is a detail view of the several sections comprising the device, each section being shown detached. Fig. 3 is a detail perspective view showing the manner of securing the sections together, one end being partly broken away. Fig. 4 is a side elevation of a slightly-modified form.

In carrying out my improvement I employ a plurality of preferably rectangular plates A, each detachable from the other and each, with the exception of the bottom plate, being The uppermost lplate has a smooth upper surface, and the bottom or base plate has a smooth under surface. For convenience of description the intermediate plates will be designated by the numerals l, 2, and 3, though it is of course understood that any desired number of plates can be used. The under surface of the top plate carries adjacent each end a downwardly-projecting doWel-pin B, which is adapted to fit in perforations or sockets B',

formed in plate l. The under surface of this plate carries dowel-pins C, arranged adjacent diagonally opposite corners of the plate. Plate 2 has perforations C', adapted to aline with the pins O, and on its under surface in the non-perforated corners are the pins D. Perforations D in plate 3 are adapted to receive the pins D, and on its under surface this .plate carries the pins E, adapted to fitin the perforations E' ofthe base-plate.

In the drawings, F represents the surface to be written upon, and the various plates secured together arev placed adjacent this surface. As the height of the writing-surface above the desk decreases the height of the arm-rest is decreased by removing the surface-plate A, and the arm or hand rests on plate I; and as the thickness of the pad is further reduced plate l is removed and plate 2 becomes temporarily the top plate, and so on untila new pad is substituted, when the rest is again built up. The rest can also be adjusted for use with any book by using the proper number of plates.

While I prefer to make the plates of hard wood, they may be made of any desired material and of any size.

In Fig. 4. a slight modification is shown, the top plate A and plates l 2 3 being the same shown in Fig. 2; but the bottom plate is lengthened, as shown at A', and extends beneath the pad, and the part A' can also be inserted beneath or between the leaves, as may be most convenient.

As previously stated, any number of plates can be used in building up my rest.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. An arm-rest comprising base and t`opi plates, removable intermediate plates, and means carried Vby the top and intermediate plates for locking them to the plate immediately beneath.

2. An arm-rest comprising a base-plate having sockets therein, a top plate having a smooth unbroken upper surface, perforated ROYAL HINDs BEASEL.
