Application: October 16, 1947, Serial No; 780,219

The present invention. relates to new and useful improvements in barber's chairs and more particularly to an auxiliary seat adapted for attaching to the chair and on which the barber may be seated while working on a customer occupying the chair whereby to relieve the barber of the strain and discomfort of standing while performing his work.

An important object of the invention is to provide an auxiliary seat of this character which is swingably mounted on the seat of a barbers chair for movement independently of the chair and also to provide a foldable auxiliary seat embodying novel means for locking the seat in a raised'position.

Another object is to provide vertical adjusting means for'the auxiliary seat.

A still further object is to provide an attachment of this character of simple and practical construction, which is strong and durable,- efficient and reliable in use, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like'numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational View showing the auxiliary seat attached to a barbers chair;

Figure 2 is an enlarged vertical sectional view, partly in side elevation, of the vertically adjustable post for the seat and showing the locking pin for holding the seat in a raised position,

the section being taken on the line 22 of Figure 3;

Figure 3 is a sectional View taken on a line 3--3 of Figure 2 and showing the seat locked in a raised position;

Figure 4 is a similar view showing the locking pin in its releasing position for lowering the seat;

Figure 5 is an enlarged group perspective view of the locking pin and stop pin therefor, and;

Figure 6 is a view in transverse section taken on the line t-6 of Figure 3.

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of my invention, the numeral 5 designates a conventional barbers chair to the underside of which is secured a horizontal plate 6 by means of bolts or the like i.

The plate includes an extension 8 cast therewith or otherwise suitably attached thereto and through which a vertical pin 9 extends and on 5- Ciaims; (Cl; -450) 2 which is journaled a hub I!) for rotation on the pin. An .arm I l extends horizontally from the hub and is formed at its outerend with an upstanding'tub'e or socket l2.

A post [3 is rotatably and vertically adjustable in the socket l2 and is formed with a plurality of vertically spaced apart annular grooves I 3 for selectively receiving a locking" ball I5 therein, the ball being. positioned in an opening It in the socket and held in lockingengagement in one of the grooves by a collar I'I' slidable on the socket. The collar is formed. in its lower portion with an internal annular chamber 18 in which the ball enters to free the ball from the grooves l4 for.verticallyadjustingv the post it in the socket [2 when the collar IT is raised. The lowering movement of the collarforces' the ball into one of the grooves t'olock the post in its vertically adjusted position.

The upper end of the post 13 is reduced as shown at l9 and is tightly fitted in a recess 20 in the underside of a block 21 to rigidly'mount the block on the post. The underside of the block at its rear edge is formed with a slot 22 in which a pivot pin 23 extends transversely of the slot and on which is pivotally mounted an arm 24 extending outwardlyfrom the front edge of an auxiliary seat 25 for vertically swinging movement of the seat from a lbweredfolded'posi tion, as shown by the dotted lines in Figure 1, to a raised horizontal position, as shown by the full lines.

The lower front edge of the arm 24 is formed with a forwardly protruding lip 26 having an inwardly curved upper edge 21 in which is seated a locking pin 28 slidably mounted in the block 2! transversely thereof and having its ends projecting from opposite sides of the block. The locking pin 28 is formed with a longitudinal slot 29 in which a stop pin 38 is received to limit opposite sliding movement of the locking pin, the stop pin being carried by the block.

The locking pin 28 is also formed with a notch 3| adjacent one end to receive the lip 26 therein upon a sliding movement of the locking pin in one direction.

In the operation of the device, the post I3 is locked in its vertically adjusted position by the ball i5 and collar I! which forces the ball into one of the grooves 14 to thus support the post in the socket !2 for free rotary movement of the post whereby the auxiliary seat 25 is free to swing horizontally.

By sliding the locking pin 28 in one direction in the block 2| to register the notch 3| with the lip 28 of arm 24, the auxiliary seat 25 is free to swing vertically on pivot pin 23 to raise or lower the seat.

After the seat has been raised the same is locked in its raised horizontal position by sliding the locking pin 28 in an opposite direction to move the notch 3i out of registry with the lip 26 whereupon the lip will engage the lower side of the locking pin and thus hold the seat in its raised position.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believ'ed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A foldable seat comprising a supporting member, an arm pivoted to said member and having a seat supported thereon, said arm being provided with an inwardly curved edge and a locking pin slidably carried by said supporting member for movement transversely of the arm into and out of locking engagement with said edge of said arm to lock said seat when unfolded and unlock the same for folding.

2. A foldable seat comprising a supporting member, an arm pivoted to said member and supporting a seat, a projection on the outer end of the arm and having an inwardly curved edge, and a locking pin slidably carried by said supporting member for movement transversely of the arm into and out of locking engagement with said edge of said projection to lock said seat when unfolded and unlock the same for folding.

3. A foldable seat comprising a supporting member, an arm pivoted to said member and supporting a seat, a lip on the edge of said arm at its pivoted end, and a locking pin slidably carried by the supporting member for movement transversely of the pivoted end of the arm and overlying said lip to hold the seat in a raised horizontal position, said pin having a notch therein to release the arm for downward swinging movement upon a movement of the pin to align the notch with the lip.

4. A foldable seat including means at one edge of the seat pivotally supporting the same to a supporting structure for vertical swinging movement, a curved lip at the pivoted edge of the seat, and locking means carried by the supporting structure for movement into and out of the path of an upward movement of said lip, said locking means comprising a slidable pin having a notch therein to release the lip when moved into registry therewith.

5. A foldable seat including means at one edge of the seat pivotally supporting the same to a supporting structure for vertical swinging movement, a curved lip at the pivoted edge of the seat, and locking means carried by the supporting structure for movement into and out of the path of an upward movement of said lip, said locking means comprising a slidable pin in said structure having a notch therein to release the lip when moved into registry therewith, and a stop pin in said structure for the locking pin to limit locking and unlocking movement thereof, said locking pin having a slot therein into which said stop pin projects.
