Other .objects of the invention are to provide 10 an adjustable piano bench of the aforementioned character which will be comparatively simple in construction, strong, durable, highly e?icient and reliable in use, compact, light in weight, attrac~ tive in appearance and which may be manufac 15 tured at low cost. ‘ All of the foregoing and still further objects and advantages will become apparent from a study of the following speci?cation, taken in con nection with the accompanying drawings where in like characters of reference designate corre 'Ifhesupporting structure ‘I vincludes legs 2‘ be tween'which ‘a plurality of braces'3 extend. The reference numeral 5 designates blocks of suitable material which are hingedly mounted on the upper end portions of the legs 2, as at 6. 5 As illustrated to advantage inFig. 7, of the draw ings, the blocks 5 are adapted to be swung up ’ Wardly on’ the upper ends of the legs 2 in a man ner to constitute vertical extensions on said legs. The blocks on the front and rear legs 2 are con- 10 nected by rods 1 for operation in unison. Removably mounted on the supporting struc ture I is a. substantially rectangular seat which is designated generally by the reference numeral 8. The seat 8, it will be observed, comprises a 15 frame 9, a top [0 and an apron ll. Mounted for sliding movement beneath the longitudinal mem bers of the frame 9 are substantially ‘U-shaped members l2. The leg portions of the substan tially U-'-shaped slidable members l2 have formed 20 sponding parts throughout the several views, and ‘ therein slots l3 which accommodate headed ele- I wherein: Figure 1 is a top plan view of an embodiment of the invention. Figure 2 is a front elevation thereof. Figure 3 is a vertical, longitudinal sectional View, taken substantially on the line 3--3 of Fig. 1, the lower portions of the legs being broken away. Figure 4 is a view in end elevation of the inven tion with the seat omitted. Figure 5 is a view in front elevation thereof. Figure 6 is a vertical sectional view through an the members I2 being‘in ‘inoperative position. '0 The next adjustment is made by sliding the upper portion of the device, taken substantially members I2 outwardly from the position shown in Fig. 8 of the drawings to that illustrated in Fig. 9, thus permitting the end portions of said on the line 6—6 of Fig. 5. members I2 to rest on the upper ends of the legs 35 > Figure 7 is a vertical. sectional view, taken sub stantially on the line ‘|--1 of Fig. 6 but showing the seat supporting blocks in raised or operative position. 40 ments I4 for mounting said members. [2 beneath the frame 9. The construction and. arrangement is such that four vertical adjustments of the removable seat 25 8 may be made. The lowest adjustment is shown to advantage in Fig. 3 of the drawings wherein the frame 9 of the seat 8 is resting directly on the upper ends of the legs 2, the blocks 9 and Figure 8 is a bottom plan view of the remov- _ able seat. Figure 9 is a bottom plan view of a corner por tion of the removable seat, showing the slidably mounted adjusting members in operative posi 45 tion. . ‘ ' Figure 10 is a vertical sectional view through an end portion of the seat, taken substantially on the line Ill—l0 of Fig. 9. Referring now to the drawings in detail, it 50 will be seen that the embodiment of the invention which has been illustrated comprises what may be referred to as a supporting unit or structure of suitable material, preferably wood, which is 55 designated generally by the reference numeral I. 2. Of course, to make these adjustments the seat 8 is removed from thesupporting structure I. The next adjustment of the seat 8 is accom plished by retracting the members I2 and swing ing the blocks 5 upwardly to operative position 40 > on the upper ends of the legs 2, as shown in Fig. 7 of the drawings. The seat 8, when replaced, rests on the blocks 5. Then, the last and high est adjustment is. made ,by sliding the members I 2 outwardly for engagement on the blocks 5. It is believed that the many advantages of an adjustable piano bench constructed in accord ance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it 50 is to be understood that changes in the details of construction and in the combination and ar rangement of parts may be resorted to which will fall within the scope of the invention as claimed. ‘6 2, 2,136,325 What is claimed is:— 1. A piano bench comprising a plurality of legs, a seat removably mounted on said legs, and mem bers slidably mounted on the seat and engageable with the upper ends of the legs for supporting said seat in elevated position thereon. 2. A piano bench comprising, in combination, a plurality of legs, a removable seat adapted to be mounted on said legs, blocks hingedly mounted 10 on the legs and engageable with the upper ends 4. A piano bench of the class described com prising a supporting structure including a plu rality of legs, braces extending between said legs, a seat adapted to be removably mounted on the legs, said seat including a frame, a top on said frame and an apron depending from the frame, blocks hingedly mounted on the upper portions of the legs and engageable on the upper ends thereof for supporting the seat in elevated position thereon, rods connecting certain of the blocks for operation in unison, substantially U shaped members slidably mounted beneath the and engageable selectively with the blocks able with the blocks for supporting the seat inv ,_ frame ‘ thereof for elevating the seat, and members slidably mounted beneath said seat and engage 15 " ~ or with the legs for supporting the seat in ele elevated position on said blocks. 3. A piano bench comprising a plurality of ‘ vated position thereon, the leg portions of said legs, a seat adapted to be removably mounted on. said legs, said seat including a frame, a top mounted on said frame and an apron depending from the frame, and a pair of substantially U shaped members slidably mounted beneath the ' frame and engageable on the upper, ends of the legs for supporting the seat in elevated position thereon.» substantially U-shaped members having slots therein, and headed elements mounted in the 1 frame and passing through the slots for slidably securing said members to said frame.
