' IMPROVEMENT IN OFFICE AND CUNTlNG-HOUSE STOOLS.

Specification forming part of Letters Patent No. 14,441, dated November 11, 1873; application filed August 21, 1873.

To all whom fit may concern:

Be :it known that I, ALFRED DEEoREsT OARTWRIGHT, of Oakland, Alameda county, State of California, have invented an Oice and Counting-House Stool; and I do hereby declare the following description and accompanying drawing are sufficient to enable any person skilled in the art or scienceto which it most nearly appertains to make and use in'y said invention without further invention or eX- peifiinent.

My invention relates to certain improvements in that class of stools which are employed for oftice and counting-house purposes; and has for its object constructing the seat that, while it is still allowed to turn about its axis, the level of the seat can be changed at ple a so as to stand at dierent angles with the horizontal plane and in reference to the position of the desk, for the purpose of relieving the occupant.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure l is a perspective view of my stool. Fig. 2 is a sectional elevation.

A A are the legs of an office-stool united in the ordinary manner, and having a stationary top or seat, B, which is perforated to allow the spindle C to pass through. This spindle is ordinarily supported in a central step upon the cross-bar D, and has the rotary seatE secured to its upper end. In order to make this seat adjustable to different angles, and thus rest the occupant, I secure a disk, F, to the crossbar D, and a ,number of holes, G, are drilled around the circumference of this disk, into any one of which the foot of the spindle C may be stepped, and this will give the seat E an inclination to the horizon. This inclination will ordinarily be made toward the desk, and it serves a two-fold purpose: First, to rest the body by a change inits position; and, secondly, to take the pressure oif the lower part of the thighs, and consequently relieve the muscles and blood-vessels oi' the compression conse quent upon the resting of the thighs across the angular edge of the stool. In order to give the feet a support, and thus still further obviate this difficulty, I make a footfrest, which consists of the foot-board H, secured in a suitable manner to the lower ends of the bars I. These bars are hinged to a cross-rod, or one of the connecting-rounds J of the stool, and they may be made to lengthen or shorten, if desired. These bars turn about the axis J, so as to adjust the foot-board to or from the stool, and staples K are xed in their sides. Hooks L of different lengths are secured to the sides of the legs of the stool, and may be,` inserted in-to the staples to hold 4the foot-board at any desired point or angle.

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

The disk F with its perforations or step Gr, in combination with the spindle O of the seat E, substantially as and for the purpose described.

In witness whereof I hereunto set my hand and seal.
