3 Claims.

This invention relates to barbers chairs and has for its general object an auxiliary seat for the barber which is revolvable substantially around the customers chair so that the barber can readily move to any position without getting off the seat. The principal object of the invention is to provide such an auxiliary seat arrangement which provides a seat supporting bar pivotally connected with the customers chair and rollably supported for movement thereabout, while providing a seat intermediate the roller support and the chair connection, and which seat is freely slidable back and forth on the supporting bar without the necessity of the barber substantially arising from the seat, or dragging the roller support back and forth with the seat movement. v

Another feature of the invention is the provision of a simplified structure of the character described, and which may be swung around the barbers chair without swivelling about its base. Also such a device in which the seat may be raised and lowered while the operator is straddling the same. Also such a device in which the main supporting bar may be Very quickly attached or detached from its connection with the barbers chair.

Other features of advantage will appear in the following description and accompanying drawing.

In the drawing:

Figure 1 is a side elevation of a barbers chair with my improved auxiliary seat for the operator shown in position.

Figure 2 is a plan View of the rollers and bracket which support the rear end of the `horizontally extending seat supporting bar as seen from the line 2 2 of Figure 1.

Figure 5 is a plan view of the clamping strap and bracket which secures to the base of the barber chair and to which the horizontally extending seat supporting bar is pivoted.

Figure 6 is an enlarged View of the forward end of the seat supporting bar showing its downwardly extending pivot which pivotally engages the bracket strapped to the base of the barber chair.

Figure 7 is a top view of the seat post plate as seen from the line l-'I of Figure 1.

Figure 8 is a side elevation, partly in section, of the sliding seat block showing one of the antifriction rollers.

The barbers chair may be of any conventional type and is indicated in the drawing at I, and provided with afloor base 2 with respect to which it may be raised and lowered in the usual manner. The base 2 is generally formed with an upwardly extending cylindrical portion, and to which is secured an arcuate cast bracket 3 which is held in place by means of a strap 4 and bolts 5 as best shown in Figure 5 of the drawing. The bracket has a rearwardly extending lug 6 `formed with a vertical hole I. Extending horizontally from the chair is a substantial steel bar 8 which turns upwardly at 9 and again horizontally at Ill, and engaging the rear end of which is a tting II provided with a downwardly extending hub l2 in which is secured a downwardly extending pipe I3, and to the lower end of which pipe is secured the hub I4 of a bracket I5 carrying at opposite ends a roller I6. The seat supporting bar 8, 9 and I0 is of a rectangular section preferably about ,-56 inch by 11/2 inches deep in cross section, and it is preferably bent hot to the form shown. At the forward end of this bar is a round pin Il slotted to extend upwardly against both sides of the bar and welded on both sides as at I8, as clearly shown in Figure 6. The forward end of the bar 8 projects forwardly beyond the vertical pin I'I as indicated at 8 so that when the pin I'I is projected downwardly through the hole 'l' of the lug 6, the projection 8' will lie upon the top of the lug as indicated in Figure 1. To prevent the pin from being accidentally lifted out of the socket thus formed, a washer I9 is placed across the lower end of the pin and secured in place as by a small cap screw 20 which threadedly extends into the lower end of the pin.

Fitting I I is secured to the rear end of portion I0 of the bar as by a set screw 2|. Pipe I3 is permanently pinned to litting II as at 22, and also to hub I4 as at 23.

Bracket I5 is formed as shown in Figure 2 to hold rollers I6 along an arc struck from a radius R which extends from the vertical center line 24 of socket pin Il. The rollers are preferably felt or rubber-tired as indicated.

Arranged on the horizontal section I0 of the supporting bar is a sliding block 25 (best shown in Figure 4). This block has a rectangular opening 26 through which to freely receive the bar I so that it may be easily slid back and forth Without effort and is tted with a pair of antifriction rollers 4| to roll on the upper edge of bar section I0. These rollers are held in place by pivot pins 52. Also passing through the block is a vertical rectangular opening 21 to receive a fiat bar or seat post 28, conveniently about 1A inch thick by one inch wide. This seat post is providedv with spaced holes 29, and its upper end is provided with a seat receiving plate 36, and to which an ordinary bicycle seat 3l is secured as by screws 32. To provide for angular adjustment of the seat, plate 3l) is provided with a depending portion 43 pivoted at 44 to seat post and secured at any point of adjustment by a bolt 45 passing through a slot 46.

The seat 3| may be adjusted up and down through the block 25 and held at any position desired by means of a latch pin 33 which is pivotally mounted at 3d between bosses 35 projecting laterally from the block as best shown in Figure 4. This latch 33 is normally forced inwardly to engage any of the holes 29 in the post by a compression spring positioned under the handle 31 of the latch.

To lower the seat the handle 31 of the latch is pushed in toward the seat post until the upper end clears the seat post 28, but the seat may be raised by simply lifting it and the latch will snap into the desired hole to lock it in place.

By the arrangement described, it will be seen that an operator seated on the seat Vcannot swing entirely around the chair I, but can swing to the limit shown by the dotted lines 4i) of Figure 5, and which is sufhcient for all purposes, especia'lly'since he'may if he wishes also swing the customer around on the vertical axis of the chair, though this is not necessary as all barbering operations can be easily accomplished without it under the circular swinging movement provided by the auxiliary seat as explained.

In carrying out his tonsorial operations, it is necessary for a'barber to constantly move nearer or further from the person being worked upon, and this he is able to do with the 'greatest ease with the construction shown, as the seat is adjusted to such a heightthat the barbers feet are always kept upon the oor so that he can move the seat with its sliding or rolling block 25 vfreely back and forth along the bar I0 by simply moving his body. This is of the utmost importance and the one thing which has been lacking heretofore in such auxiliary seats as havel been proposed, but which have never come into use', and it isthought principally through lack of this feature.-

Also' in order to adjust the seat vertically the barber need only pull the seat. up with one hand, or lowering the seat by pressing the lever or handle 31, without getting off, it being merely necessary for him to take his weight off of it for the moment in adjusting the seat vertically.

To disconnect the apparatus from the chair the' nut 2D is simply unscrewed (or may be omitted entirely) and the bar 8 is lifted out of the socket.

I am aware that prior patentees have tried to provide auxiliary seats for the same purpose. Also these seats have included means for swivelling the device around the barbers chair and arcuately disposed supporting rollers in the outer end. However, in any of the prior designs with which I am familiar, the barber could not adjust his position in and out from the chair without dragging the floor rollers with him, and which manifestly developed so much friction that he would have to get off the seat to do it. Other devices of this kind lacked any outboard roller support and therefore made it impossible to slide a seat back and forth on their extension on account of the great friction set up. One of the most important features of the present construction is the perfectly free slidable or rollable seat block 25 in combination with the rigid horizontally extending bar I0 firmly supported at both inner and outer ends by means of its connection to the chair at one end, and the post I3 and rollers at the other end, so that there is no binding action of any kind on the block and the barber is always free to slide back and forth by simple body movement.

Having thus described my invention and its advantages, what I claim is:
