CHAIR ATTACHM ENT.

SPECIFICATION forming part of Letters Patent No. 560,044, dated May 12, 1896.

Application filed December 30,1895. Serial No. 573,780. (No modelf) To all 20700711/ t may concern-.-

Be it known that I, Enom I. NICHOLS, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Chair Attachments; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and t'o the letters of reference marked thereon, which form a part of this specification.

My invention is an attachment for chairs, and is also intended to be used and operated in other places. It is designed to -furnish a moving part carrying and displaying any desired pictures, notices, or advertisements, which are thus better adapted to attract the attention than a stationary picture, notice, or advertisement. These movable pictures, notices, or advertisements are well known, and my purpose is to provide a cheap and eiective mechanism and combination by means of which they may be exhibited in hotels, resorts, and other public places.

My invention consists of a chair or an attachment provided with an endless movable part or parts carrying pictures, notices, or advertisements, and with mechanism for moving the said part or parts.

My invention is illustrated in the accompanying drawings, in which- Figure 1 represents a perspective view of a rocking-chair with a portable attachment secured thereto. Figs. 2 and 3 show an edge and front view of a sectional carrier, also the strengthening-pieces on part of the carriers. Fig. 4 shows a modified form of connecting the sections of the carrier. Fig. 5 shows the sections of the carrier secured to the side of a sprocket or driving chain. Fig. 6 represents a vertical section of a rocking-chair, taken from front to rear, showing a recess formed in the back of the chair for the carriers. Fig. 7 shows a front view of the upper part of the back of a chair. Figs. 8 and 9 are iront and side views of a portable attachment. Figs. 10 and 11 are front and side views of the top of a portable attachment, showing three open or clear spaces for exposing the notices. Fig. 12 represents a vertical section of a chair and a side view of a portable attachment. Fig. 13 shows a front view of the operatin g mechanism with the cover removed. Fig. 14 shows a partial horizontal sectional view of the operating mechanism. Fig. 15 shows a modification of the operating mechanism with the cover removed. Fig. 1G is a modication of the carrier, showing an angular link chain for attaching flexible cards o r a continuous flexible sheet.

In the drawings I have shown at A the back of the chair, and in Figs. l and 12 I have shown at B an attachment secured to the back A, as in this form the notices, which for convenience I will call notices', are displayed in the front and rear of the chair. The said attachment B or the back A, as shown in Fig. 6, is made sufliciently high to allow the notices to appear above the head of the occupant of the chair in or upon the said attachment or the chair-back. I arrange in the attachment B or in the chair-back A the movable part or parts on which the notices are carried, and for convenience I will call these the carriers C. I have shown these carriers in the form of cards or plates loosely joined together, forming an endless chain, band, or web adapted to be moved past an open or clear space on their edges, eXposin g the notices on their sides, and these carriers may be of any desired shape and of any suitable material, such as cloth, paper, wood, or metal. The upper end of this carrier is supported by the sprocket wheel or roll a, which is journaled in the up per end of the attachment or the chair-back. The lower end of the carrier passes around the driving sprocket wheel or roll b, which is secured to the shaft c of the operating mechanism D, all of which is secured to the end of the attachment B or the chair-back A,the sprocket wheels or rolls a and h, as shown in the drawings, have four sides; but they may have any number of sides or may be round, but I prefer them as shown, as this gives a larger surface of the cards or plates exposed to view.

As shown in Figs. 1, 8, 9, 10, 11, and 12, the chain or carrier is inclosed in an independent casing made of any suitable material. In Fig. 6 I have shown a recess formed in the back of the chair for the reception of the carrier but it is operated the same as in the inde- IOO pendent casing. I prefer to make this an independent casing or attachment, so the same may be attached to most any chair now in use, 0r may be used independent of a chair, if so desired.

The moving of the carrier may be effected by any turning mechanism adapted to bear on the Hoor, base, or under the chair-seat and to be rendered operative by the rocking, the weight, or other movements of the occupant of the chair or other suitable means for giving the required movement to the carrier for exhibiting the notices, and as a convenient form of such operating mechanism I have shown in the drawings a device for moving the carriers and giving them an intermittent or continuous movement, but I do not confine myself to this. It is easy to devise or adopt some other mechanism for moving the carriers and giving them the required movement,whether directly or indirectly connected therewith.

In Figs. I3 and 14 I have shown an operating device in the form of a casing E with a shaft c journaled therein. On the outer end of this shaft is secured the sprocket or roll l). On the inside of the casing is the disk F, secured to the shaft c. Pivoted on the side of this disk is the pawl e, bearing at its outer end upon the inner periphery of the casingE and against the abutment f, being held toits work by the projection g on its inner end, which travels in the groove h on one side of the disk G. The disk G is loosely journaled on the shaft c and, as shown in Figs. I3 and 14, is rotated by the movement of the arm H. The inner end of this arm is pivoted on the shaft e, and the outer end engages with a pin j, as shown. Secured to the upright rod I in a recess or pocket formed in the arm H is the ball 7e, that bears against the outer periphery of the smaller diameter of the disk G and the wedge-shaped side of the pocket in the arm H. In a recess or pocket formed in the casing E is the ball Z, that bears against the outer periphery of the larger diameter of the disk G and the wedge-shaped side of the pocket. This ball serves as a check as the arm His making its downward movement. One end of the spring a, as shown by dotted lines in Figs. 13 and 15, is secured to the disk F and the other end is secured to the disk G. The operating-rod I, as shown, has an abutment 0. Between this abutment and the casing is the spring K. The reverse action of the rod I is caused by this spring, which holds the rod I to the iioor, when used as shown in Figs. l and 6, where the pressure comes on the lower end of rod I, but when used as in Fig. 12 or any place where the pressure comes on the upper end of rod I to operate the device the spring K is placed below the abutment o.

In Fig. l5 I have shown a dierent form of rotating the disk G. In this form I do'not use the arm H or the balls k and Z, but, as shown, the disk G is rotated by the pawl p,

and b. This gives a large number of cards or' plates for exhibiting notices in a small space, and also when it is desired to change a notice it can be quickly accomplished by removing the card containing such notice and substituting another therefor. I have also shown in Fig. 3, at s, a reinforcement or strengthening-piece secured to or connected with the cards or plates for taking part of the strain of the cards or plates when the cards or plates are made of paper or other light material. This strengthening-piece may be of paper or other light material secured to thc side or sides of said cards or plates.

In Figs. 10 and 11 I have shown the upper part of an attachment or chair-back designed to have two carriers, and, as shown, has three open or clear spaces L for exhibiting the notices, but may be operated by one operating mechanism. v

In Fig. l2 I have shown a chair with an attachment secured thereto, with the end of the operating-rod I bearing up under the seat of the chair, and is operated by the weight of the occupant of the chair.

I have illustrated in several of the views a convenient arrangement for exposing the notices, as shown at L, which is xed on the cards or plates of the carrier, and is carried thereon intermittently by the moving mechanism to the apertures L in the attachment or the chair-back, where it is exposed to view for a while and then moved on, and another takes its place. Thus in succession by the movement of the occupant of the chair the whole series, which may cover the surface of the cards or plates of the carrier, is brought into view, every one moving into and out of view, attracting attention by their motion, and eX- posing several notices in the space necessary for only one.

The intermittent movement of the carrier is accomplished by the operating mechanism, as follows: By the upward and downward movement of the rod I the disk G is rotated a given amount, or until the abutment w in 1 ment f. This rotates the sprocket or roll Z2 one-fourth of a turn and brings the next no- IOO IIO

tice to view. This forward movement of the disk F is caused by the spring n being secured at one end to the disk G and the other end being secured to the disk F.

I have shown the attachment secured to the back of a chair, but it may also be attached to the side of the chair or under the arm or arms of the chair.

I do not confine myself to this form of a carrier, as shown operated in a recess in the back of a ch'air. The carrier may be made in many different forms and operated on or in a chair-back.
