No. 567.320. Patented Sept. 8, 1896.




SPECIFICATION forming part of Letters Patent No. 567,320, dated. September 8, 1896. Application 1115a 0655b 8,1895. Serial No. 555,095. (No 155551.)

To all whom it may concern.-

Be it known that I, ALBERT R. MILNER, a citizen of the United States, residing at Can- 'ton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Automatic-Acting Stools; and

I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings,

' making a part of this specification, and to the letters of reference marked thereon, in which I Figure 1 is a perspective view showing the stool in its normal position. Fig. 2 is a vertical section of the base, showing the bottom or lower end of the leg properly attached with reference to the base. Fig. 3 is a view showing the top or upper end of the leg and illustrating the seat-connecting plate properly attached thereto. Fig. 4 is an edge view of the base and seat, showing the seat in its normal position. Fig. 5 is a perspective view of the stool, showing it placed in proper position for use. Fig. 6 is. a detached view of the seat- 2 5 spring.

Similar letters of reference indicate corresponding parts in all the figures of the drawlngs.

' The present invention has relation to an- 0 tomatic-acting stools 5' and it consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the claim.

In the accompanying drawings, A repre- 5 sents the base, which may be of the form shown, or it may be of any other desired form, reference being had to properly attaching the leg B, as hereinafter described. The top or upper part of the base A is provided with the 40 opening a, which opening is for the purpose of receiving the bottom or lower end of the leg B, substantially as illustrated in the drawings. The bottom or lower end of the leg B is pivotally attached to the base A by 5 means of the cross-pin b, which cross-pin is formed of a length greater than the width of the base, and is so formed for the purpose of attaching the spring 0 by means of the loops 0 formed in said spring. The spring 0 is ex- 5o tended upward a short distance above the base A and engages the leg 13, substantially as shown in Figs. 1 and 5. The object and purpose of the spring 0 is to throw the leg B forward when it has become freed, as hereinafter described. To the top or upper end of the leg B is pivotally attached the connecting-plate D, which connecting-plate may be of the form illustrated in thedrawings, and as shown it is provided with the flanges d and d. The flanges d are for the purpose of providing means for pivotally connecting the plate D to the leg B, and the flanges d are for the purpose of forming stops to. hold the plate D, together with its seat D, in a horizontal position, as illustrated in Fig. 5. For the purpose of automatically tilting the plate D and its seat Dinto substantiallya vertical position, as illustrated in' Fig. 4, the springs 'E are provided, which springs are provided with the tangs f and f, one set of which tangs are designed to rest in the groove g and the 1 other tangs in the groove 9, the groove 9 being formed in the leg 13 and the groove g in the plate D, said grooves being for the purpose of holding the tangs in proper position and at the same time providing suitable casings or receptacles for said tan gs. In use the base A is securely attached .to the floor by means of suitable screws or other equivalents, said base being located at a point with refer 8o en'ce to the use to which the seat or stool is to be used, so as to bring the stool proper out of the Way When not in use,

When it is desired to place the stool in position for use, the leg Bis brought in the position illustrated in Fig. 6 and the seat D turned so as to bring it into the position illus trated in said Fig. 6. It will beunderstood that when the seat D has become freed or out of use the spring 0 will automatically 9o elevate or throw the leg B into the position illustrated in Fig. 1, and the spring E will automatically tilt the seat D into the position illustrated in Fig. 4, thereby bringing the stool out of the way. In use the seat D may be securely attached to the top or upper end of the leg B, the said seat carried back and forth with the movements of said leg, without changing the position of the seat with reference to the leg itself, it being un-- :00

derstood that the angularities of the seat Will correspond with the different angles or positions of the leg.

It will be understood that by my peculiar construction I am enabled to produce a perfect automatic-acting stool Without any additional or auxiliary attachments to produce the desired and above-described results.

I do not desire to be limited to the particular construction shown for automatically moving the leg B, as it is evident that many other Ways and means may be employed to produce the same result Without departing from the nature of my invention, the main object being an independent-acting stool or seat. 7

Having fully described my invention, What ALBERT R. MILNER.
