To alt whom it may concern:

Be 1t known that we, WILLIAM Hear and JOHN T. BRAUND, subjects of the Queen of Great Britain, and residents of Muskegon, in the county of lliiuskcgon and State of Michigan, in the United States of America, have invented certain new and useful Improvements in Piano or other Stools, of which the following is so full, clear, and exact a description as will enable others skilled in the art to which our invention appertains to make and use the same, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of our improved piano-stool, showing the tongues or keys, by means of which the supporting-feet and the standard are secured together, as formed integral with said standard and running from top to bottom thereof. 2 is a top plan of the same in section and shown as having three supporting-feet. Fig. 3 is a similar view shown as having four supporting-feet. Fig. 4 is likewise a similar view showing a different form of the keys or tongues and the grooves, by means of which the combined feet and standard are secured together. Fig. 5 is a side sectional view showing the mechanism for permitting the adjustment of the seat. Fig. 6 is a plan of the washer. Fig. 7 is a plan view showing outline shape of plate and top view of perpendicular hooked rods and turningcam. Figs. 8, 9, and 10 are views showing different devices for disengaging the forked rods from their bearing.

Like letters of reference designate corresponding parts in the several views.

The object of our invention is to provide a piano or organ stool or a like article of furniture which shall be simple and cheap in con struction and of great durability.

Another object of ourinvcntion is to provide mechanism whereby the seat may be raised or lowered to any desired height; and to these ends our invention consists in certain peculiarities in the construction, arrangement, and

combination of the various parts, substantially as will be hereinafter fully described, and then more particularly pointed out in the appended claims.

In the accompanying drawings, A represents a hollow standard, which may have a screw threaded interior adapted to receive a screw, a, which carries the seat I), and by means of which the said seat is raised or lowered, when desired, in the same manner as in the ordinary 5 5 devices of this class. This standard A is upheld and supported by any desired number of feet, B, which are preferably formed integral therewith and secured together in the manner hereinafter described but the said feet may be formed with a central perforation adapted to receive astandard, instead of being formed integral therewith. In the construction of a piano or other stool having four supportingfeet (shown in Figs. 3 and 4) the said feet are formed with longitudinal grooves and mortises running through their entire length, which re ceive keys or tongues 0, running from one of the said feet to another, as shown, and which keys are secured within the grooves by gluing or otherwise.

Obviously the keys or tongues O and the grooves may be made in various ways and of various forms. They may be made, if desired, of a greater width toward their eXtremi- 7 5 ties, and they can be undercut, so as to form dovetails, as shown in Fig. 4, or they may be made perfectly straight, as shown in Figs. 2 and 3 but we prefer the first-mentioned form,

as it makes a more rigid joint and prevents the possibility of the parting of the supporting'feet, and thereby insures greater strength and durability.

Fig. 2 shows the stool as having but three supportingfect secured together and adapted 8 5 proved piano or other stool together we pro- 5 ceed as follows: As before stated, each foot is preferably so formed as to make a portion of the standard, and they may be of a great va riety of designs. Having cut out and prepared the pieces B, and the edges meeting in I00 taneously by the cog-wheels 17 17.

the center having been jointed, grooved, and shaped, and slots for the keys C having been made, also keys prepared, one of the slots is glued and into it is driven one of the keys. The slot in the next piece is then glued and it is driven onto the key. This is repeated until all the pieces l5 have been brought together. The two remaining; slots are then glued and the last key driven down lengthwise. The whole are then clamped home and after hardening a most solid and durable structure is formed.

When the feet and standard are made separately, the edges of the said feet will be so formed that when put together it will form a receptacle for the said standard, which may be of any desired form.

In order to adjust the seat of the piano or other stool to any desired height, we may employ the ordinary screw, or we may use the device shown in Figs. 5 to 10, inclusive. In these figures, 1 1 represent perpendicularrods having a series of notches, 9, forming hooks. These rods 1 1 are pivoted to a washer, 2, situd ated at its lowermost extremity, and which is so shaped as to give plenty of side hearing, so as not to cut away the wood and to keep it in a firm position. These rods 1 1. are also pivoted to a top plate, 3, to which is secured the seat proper. Cast or otherwise formed upon the upper ends of the rods 1. 1 is a finger, 4, above which rises the pivot of the said rods 1. 5 represents a cam pivoted to the top plate, 3, at 6, and which meshes with the finger 4-. Screwed to the top of the standard is a plate, 7, having an inwardly-turned flange, S, preferably made in the form shown, upon which the notches 9 upon the perpendicular rods 1 are adapted to rest. Numerous ways or devices besides the cam 5, meshing with the fingers 4. 4, can be employed for turning the rods 1 1 inward, so as to clear the lug or projection 8 and allow the seat to be adjusted as required. For example, in Fig. 8 the perpendicular rods 1 1 are shaped slightly different from that shown in Fig. (3; but they still have the hooks to catch upon lugs or projections 8, and these rods can be turned inward to clear the lugs 8 simultaneously by the two ways shown in Figs. 9 and 10, in Fig. 9 the disks 1.5 taking the place of the finger in Fig. 7, 16 being strong wire fastened to the disks 15, as shown, but working pivotally. In Fig. 10 the disks 15 have cogs and are turned inward simul- The cam is preferably provided with a rod, 18, having a' handle, 19, connected to it loosely, and a spring, 20, as shown, which mechanism may obviously be used, whether the cam 5 or any of the plans delineated in Figs. 8, 9, or 1.0 are adopted. The manner of operating is as follows: \Vhen it is desired to adjust the stool or chair to any height, the user grasps the under side of the seat, when the fingers come in contact with the handle 19, upon pressing which the cam 5 (if this plan is adopted) turns upon its pivot,which of course turns the rods 1 1 inward toward the center, so that the interlocking teeth or hooks will clear the lugs 8, allowing the seat to be raised or lowered at will. .Vhen the pressure is removed from the handle,the springs 20 will immediately cause the cam to return to its normal position, and the hooks 9 of rod] will again interlock with lugs 8.

The hooks 9 are so shaped that when resting upon the iuwardly-turned flange 8 of the plate 7 they form a solid bearing for the seat proper, so that it can be revolved at pleasure without altering the height of the device.

Although we have described our inventiom as being applied to a piano or organ stool, it may he obviously applied to a center-table, ofilce or other chair, and, in fact, to any of the various articles of furniture having a central standard to which are secured supporting-feet.

Obviously the parts of which our stool is composed may be made in quantity and kept in stock and the stool formed in a very few minutes after an order is given. Furthermore, it will be seen that the cost of mannfactu re of the stool will be reduced to a minimum. Furthermore, it will be readily seen that round,

square, or other shaped mortises for the reception of such nuts, screws, or other shaped irons as it may be necessary to place within the standard can be more easily formed in this improved structure before the parts are put together than they can be bored or worked out in a solid standard, and this obviates the necessity of especially-skilled workmen.

Having now set forth the objects, uses, and advantages of our device, and having described a preferred manner of carrying the same into practice, what we believe to be new, and desire to secure by Letters Patent, and what we therefore claim, is

1. The stool-pedestal having'three or more legs radiating from a center and having grooves in their sides at the exterior angles formed by the intersections of the legs, in combination with a series of keys extending across said angles and engaging said grooves for securing the legs together, substantially as shown and described.

2. In a piano or other steel, the combination, with the supporting-feet and the seat proper, of a plate secured to the top of the said feet and formed with an inwardly-turned flange, and the forked rods engaging with the said flange, together with means for disengaging the rods from the flanges to allow the seat to be adjusted vorticall y, substantially as described. 3. The C0llJbiU1biOll,Wii)il thesupporting-feet and seat proper, the plate secured to the top of the said feet and formed with an inwardlyturned flange, of the pivoted forked rod adapted toengage with the said flange, and means for disengaging them by causing the said rod to turn on its pivot, substantially as shown and described.

4:. In a piano or other stool, the combination, with the supporting-feet and seat proper and a plate secured to the top of the said foot, formed with an inwardly-turned flange, of pivoted forked rods engaging with the said flange, together with means for disengaging them, consisting of a cam meshing with fingers secured to the said forked rods, and means for operating the cam, substantially as shown, and for the purpose herein described.

5. In a piano or other stool, the combination, with the supporting-feet and seatproper and a plate secured to the top of the said feet, formed with an inwardly-turned flange, of pivoted forked rods engaging with the said flange, together with means for disengaging the forked rods from the flange, consisting of a cam meshing with fingers secured to the said forked rods, and a rod secured to the said cam and provided with a handle and a spring, all combined and arranged to operate in a manner and for the purpose substantially as shown and described.

6. In a piano or other stool,-the combination, with the supporting-feet constructed in such a manner, as described, that when secured together they will form combined feet and standard, the seat proper, and a plate secured to the top of the said feet formed with an inwardly-turned flange, of the forked rods engaging with the said flange and pivoted to a top plate and to a washer, as shown, and means for disengaging the forked rods from the flange, consisting of a cam meshing with fingers secured to the said forked rods, and a rod secured to the said cam and provided with a handle and a spring, all combined and arranged to operate in the manner and for the purpose substantially, as shown.

7. In a piano or other stool, the stool-pedestal consisting of three or more legs radiating from a center and having grooves in their sides at the exterior angles formed by the intersection of the legs, keys extending across said angles and engaging with the grooves for securing the legs together, in combination with the seat and the devices for raising and lowering said seat, substantially as shown and de scribed.

In testimony that we claim the above as our invention we hereunto set our hands.
