ROVING SEAT FOR BARBER AND SIMILAR CHAIRS Clarence M. Boles, Madera, Calif. Application January 5, 1946, Serial No. 639,321

3 Claims. (Cl. 155-81) The present invention relates to roving and travelling seats, stools and similar attachments such as are used in connection with chairs employed by barbers, dentists and the like, to provide a convenient and readily maneuverable seat for the user, whereby to reduce fatigue such as attends long standing periods.

It is evident from the introductory paragraph that I am sufficiently conversant with the state of the art to which the invention relates to realize and appreciate that attachments in the category stated are not in any sense of the word broadly new. As a matter of fact, there are quite a number of similar attachments already patented. It follows, therefore, that the purpose of the present invention is to generally, specifically and otherwise improve upon known patented and marketed roving style seats and stools.

In carrying out the principles of the present invention I contemplate the adoption and use of a sectional clamp to embrace the pedestal of the chair, said clamp serving to accommodate a hinge, and said hinge serving, in turn, to accommodate a horizontal leg and roller equipped carriage. The carriage serves as a support for the seat unit and the seat unit is adjustable in dependently of the swinging motion, whereby to make it possible for the occupant of the seat to not only move around in arcuate paths to take positions of vantage in relation to the occupant of the chair, but to independently shift the seat toward and from the chair occupant for best results.

In continuation of the above it will be observed, as the description proceeds, that the drawings disclose two embodiments of the invention and that the :preceding survey, structurally and functionally speaking, is generic to both forms. It is therefore an object of the invention to provide a so-called roving seat for barher and similar chairs which is capable of being reduced to practice and carried out in a number of diiferent ways while remaining within the realm and scope of the instant disclosures thereof.

More specifically stated, it is a further object of the invention to provide a new type of carriage, this being in the form of a horizontal tubular arm hingedly attached to the pedestal clamp by way of an appropriate hinge, said carriage being primarily characterized by a slotted tubular arm, the latter to receive a T-shaped unit of the jack assembly and the jack assembly including an adjustable seat Whose elevation may be raised and lowered to advantageously and comfortably accommodate the barber or other user. i

In addition to the above, a still furtherob'ject of the invention is to provide a form or version thereof in which an inverted channel iron is integrally connected with clamping means at tached to the pedestal said channel iron constituting a novel casing for an arrangement of parallel interiorly disposed tracks, said tracks serving to accommodate axles and rollers forming a truck-like adjuster, the standard. of the seat being attached to said adjuster and operating back and forth in a slot provided therefor in the web of the channel iron.

Other objects, features and advantages will become more readily apparent from the following description and the accompanying illustrational barber chair with the roving seat attach-v ment applied thereto ready for use.

Figure 2 is a horizontal section, slightly en-v larged, this on the plane of the horizontal line 22 of Figure 1, looking in the direction of the.-

arrows.

Figure 3 is an enlarged, in fact an exaggerated, cross-section taken on the plane of the line 3-3 of Figure 1 looking in the direction of the arrows.

Figure 4 is an elevational view showing a fragmentary portion of a pedestal, the clamp thereon and a modified version of the invention.

Figure 5 is a top plan view of the assembly as seen in Figure 4.

Figure 6 is an enlarged transverse or cross sectional view this taken on the plane of the line 6--6 of Figure 5. Figure '7 is a sectional view of a fragmentary type and with parts in elevation, showing details appearing on the vertical line SI-l of Figure 6.

Figure 8 is a sectional view of a detail along line 8-8 of Fig. 3.

Referring now to the drawings (Figures 1 to 3 only) by distinguishing reference characters, it will be seen that the barber chair is conventional, the same denoted at A and having the customary stand or pedestal B. It is to, the basal portion of the pedestal that the improved roving stool or seat invention is applicable. In fact, and as before explained, I properly accomplish this by adopting a suitable two-part or sectional clamp taken 4. This is made up of duplicate half-sections 5 which are bolted together as at 6. The end portions 1 on the rear side of the clamp serve to accommodate a heavy duty or sturdy hinge. The hinge is indicated at 8 and one leaf is secured by the bolts 6 between the clamp-ends I and the other leaf is bolted, as at '9, between furcations ID on the inner end of the carriage I l. The carriage is referred to as a unit and is characterized primarily by a horizontal tubular arm [2. The inner end of the arm, as before indicated, is bifurcated. The opposite end is provided with lateral branches 13 which are down bent to provide supporting legs. The legs are provided on their lower ends with suitable automatic swivelling casters 14. The upper half portion of said tubular arm is formed with anelongated slot 15 running between upstanding parallel guide flanges [6.

The seat means comprises an appropriate saddle or .seat I8 mounted atop a feed or jack screw l9. The screw threads down into the screw threaded bore of the standard portion 29 of the jack 2|. The lower end of the standard is provided with a right angularly disposed cylindrical head 22 and the two parts 28 and 22 form a sort of T-shaped stand. What is more, the outer ends of the head 22 are provided with ball bearings 23 held in place by retaining discs 24. The complete assembly provides a readily shiftable seat, that is, a seat which, as a unit, can be slid and moved back and forth in relation to the carriage while the carriage swings freely in arcuate paths and in a horizontal plane in relation to the barber chair.

Attention is now directed to the modified form or style of the invention depicted in Figures 4 to 7 inclusive. Referring to these figures it will be seen that the clamp on the pedestal B is denoted by the numeral 25 and comprises complemental bands or clamping half-sections 25. Coacting therewith is a double leaf hinge 2?, the leaf 28- being fixed between adjacent ends of the halfsections 26 indicated at points 29. The remaining leaf 3!] is bolted as at 3| between furcations 32 on a tapered adapter cap 33, the latter being connected, in any suitable manner, to the inner end of the carriage 34-. As before stated this carriage is primarily made up of an arm or casing of hollow or tubular form. More specifically as shown in Figure 6, it comprises an inverted channel iron whose web 35 is provided with an elongated slot 36-. The side walls are spaced and parallel as indicated at 31 and have. depending outer or free, end portions 38 which may be conveniently defined as a shield-like apron. A crosspiece 39 is arranged between these ears and provided with swivelly mounted casters or rollers 40 to render the unit 3 1 freely movable in an obvious manner.

Referring further to Figure 6 it will be seen that I provide a wheeled or roller equipped truck 4 embodying a pair of axles t2 with rollers 43 mounted on the outer ends thereof. These rollers operate in upper tracks M on the top wall of the channel and channel shaped tracks 45 arranged therebeneath. The standard or upright means 4-5 which serves to support the barbers chair is attached to a plate 47 which, in turn, is connected as at 48 with said axles. Thus, we have a chair on a small wheeled truck unit and the truck unit operating in the main channel 34 directly in the tracks 2-4 and 65 mounted in said channel. This provides the desired independent back and forth or sliding movement of the barbers stool in relation to the swingable arm or carriage 34.

In both forms of the invention we provide a carriage which is characterized by a horizontal member either a channel or a tubular member, whichever is desired, said member being horizontally arranged and at right angles to the pedestal and being wheel supported so that it works and rolls freely in relation to the floor and chair. Then a heavy duty hinge provides a connection between the inner end of this and the clamp means on the pedestal. Preferably the roller means for supporting the carriage is at the outer end thereof and suitably and swivelly constructed. In addition to the above there is the barbers stool or seat which has means whereby it is shiftably mounted on the carriage. The claims are to be read and interpreted accordingly.

It will be appreciated from the drawings and description that the attachment is unusually simple in construction, durable and eilicient and otherwise advantageous and I do not desire to restrict myself to any particular kind of a clamp nor to the type of pedestal equipped-chair with which the clamp is connected for anchoring the carriage.

It is evident too that the invention constitutes an auxiliary seat to support the barber while he is comfortably seated and appropriately engaged at work.

It is further evident that the invention fulfills the requirements of a chair, seat or stool of the roving type, and that all seemingly essential facilities have been adopted and brought into proper organization to achieve the desired ends.

I desire to stress the phases of the invention which permits the carriage, working on a vertical pivot to swing freely in a horizontal plane, the type of hinge and the clamping means provided, the adjustable T-shaped part 2i 0f the seat unit or jack, and the fact that this is ball bearing equipped and slips back and forth easily in relation to the slotted carriage arm to function properly while, at the same time, allowing the seat ill to be vertically adjusted.

A careful consideration of the foregoing description in conjunction with the invention as illustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty sufficient to clarify the construction of the invention as hereinafter claimed.

MinOr' changes in shape, size, materials and rearrangement of parts may be resorted to in actual practice so long as no-departu're is made from the'invention as claimed.

I claim:

1. In a structural assembly of the class described, in combination, a vertical pedestal for a barbers chair, clamp means embracing and clamped on said pedestal, a hinge connected with said clamp means, a cap connected with said hinge means, a roller supported carriage connected to said cap, a barbers seat, and means for adjustably mounting same on said carriage, said carriage being in the form of an inverted channel iron with its outer end downturned and provided with swivelly mounted casters, the web portion of said channel iron being slotted, said mounting means passing through said slot.
