This invention relates to a barber chair and particularly for means for elevating the seat with respect to the rest of the chair.

In barbering operations it is customary to provide an adjustable seat in which the customer may be seated and elevated to the proper height for the barber to do the proper operations on the customer. For very short or juvenile customers it is customary to provide an adjustable seat which brings the head of the customer above the back of the chair so that the barber may conveniently perform the operation necessary thereon. While such an adjustable seat is satisfactory for small infants or younger children it is too high for most of the older children and they must sit on the seat, in which event the head of the customer may be below the back of the chair so that it is very inconvenient for the barber to perform the necessary tonsorial operation thereon.

This invention provides an adjustable seat which is adjustable with respect to the rest of the chair so that a customer of any size may be properly elevated with respect to the back of the chair so that the barber may conveniently perform the necessary operation thereon.

According to this invention this is accomplished by providing an elevating system adapted to be connected to the seat of the chair and provided with a base member for elevating the seat with respect to the frame of the chair.

It is accordingly an object of this invention to provide an improved barber chair.

It is a further object of this invention to provide an apparatus for elevating the seat of a barber chair with respect to the frame of the chair,

It is a further object of this invention to provide an automatic device for elevating the seat of a barber chair.

Other objects and many of the attendant advantages of this invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings in which:

In the exemplary embodiment of the invention, a barber chair has a base Ill in which is telescopically mounted an extensible standard [2 on which is mounted a chair frame I having a seat H5 and a back It. The back It is fixedly arranged on the frame Hi. Provided in what is known as an elevator chair, the standard l2 may be telescoped with respect to the base It by means of a suitable apparatus, usually a hydraulic jack having the usual operating handle I I.

In order to adjust the seat It with respect to the back I8 and the frame It, I have provided a pair of side bars 26 and 22 which are rigidly anchored on the chair frame M. Any suitable anchoring means of sufilcient rigidity may be utilized, however, I prefer to use a clamp and bolt arrangement 24 and 2%- usually clamped on to a portion of the frame it. The side bars 251 and 22 may extend completely across the front and back of the frame I 4 or if the frame It has sufficient reenforcement adjacent the center thereof the bars 26 and 22 may terminate short of the front edge of the seat as illustrated in this particular embodiment. Each of the side bars 20 and 22 is provided with a pair of tubular guides 30 and 32 which may conveniently be constructed as a portion of a pipe nipple which is reamed out to a sufficient inside diameter and has lock nuts 34 and 36 to properly fasten the guides into the side bars 20 and 22.

slidably mounted in each of the guides are extension rods 40 on the top of which is rigidly mounted the seat I6. Most of the barber chairs with which I am familiar are provided with a frame work on the bottom of the seat I6 and it is only necessary to provide openings therein and insert the tops of the rods 40 and provide lock nuts on each side of the frame 42 of the seat I6 to properly secure the seat to the tops of the rods 40. However, it may be possible that there are seats without such frame work in which case it would be necessary to provide a suitable frame for attachment to the rods 40.

The bottom ends of the rods 40 are likewise threaded and each pair of rods 40 is provided with a shoe 44 which is conveniently constructed a a loop of flat spring material. The shoes are provided with suitable openings and have inserted therein the lower ends of the rods 40 which are held in place by means of lock nuts 46 and 48,

A base collar 50 is mounted on the top of the base I and is rotatably mounted around the standard I2. The base collar 50 is of greater length than width so thatit can be'rotated in one direction so that it will fit between the pairs of shoes 44 and rotated in the other direction it will extend transversely across the path of motion of the shoes 44 so that when the chair is elevated the collar 50 may be rotated to pass under the shoes 44. When the collar 50 is rotated so as to intercept the path of travel of the shoes 44, the chair frame l4 may be lowered by means of the column I2. The extension rods 40 will slide in the guides and 32 so that the seat I6 will remain stationary while the frame I4 is lowered.

While this provides sufficient adjustment between the back of the chair it is frequently desirable to elevate the entire chair to perform certain operations during the hair cutting or other tonsorial operation. Accordingly a locking means has been provided for securing the seat I6 in an elevated relation to the frame I4. The locking device comprises a pair of locking bars 52 and 54 which are overlying the side bars 20 and 22 and are longitudinally slidable with respect thereto.

The locking bars 52 and 54 are connected to the side bars 20 and 22 by means of bolts 56 rigidly connected to the side bars 20 and 22 and slidably connected to the lock bars by mean of the slots 58. The lock bars 52 and 54 are provided with a pair of key hole slots 60 and 62 having the large ends of sullicient size to slidably engage the extension rods 40. The extension rods are provided with reduced sections 64 which are receivable in reduced portion 66 and the key hole slots 60 firmly anchor the rods 40 with respect to the lock bars 52 and 54. The lock bars are arranged for automatic operation by means of resilient devices such as spring 10 connected to an opening "I2 in the locking bars and anchored in any convenient place on the frame I 4 such as the lock bar I4. The lock bar I4 is conveniently attached to the side rods by means of the lock nut 36 on the guide 30. A pin I6 may be inserted in the lock bar 14 to prevent its rotation about the guide 30. The locking bars 52 and 54 may be returned to the unlocked position by means of a suitable manually controlled handle 80.

In operation of the device the chair is elevated to a maximum elevation by means of a hydraulic jack after which the collar is turned to intercept the path of travel of the shoes 44. The chair is then allowed to return to its lowered position at which time the shoes will be intercepted by means of the collar 50 and raise the seat with respect to the frame I4 and the rods 40 slide through the key hole slots 60 until the reduced portions 64 of the rods 40 will make contact with the reduced portion 66 of the key hole slots and the spring I0 will urge the locking bars into locking position so that the seat I6 is an chored with respect to the locking bars 52 and 54. After the seat I6 has been anchored with respect to the frame I4 the hydraulic jack may be used to raise the frame I4 together with the seat I6 so that the chair may be operated at any desired height.

Instead of the sprin shoes 44 it is sometimes desirable to use a straight bar shoe connected to the lower end of the rods 40 by means of connectors 92 having bi-furcated ends embracing the bar 90 and connected thereto by means of suitable fasteners such as rivet 94.

In barbering operations on people of les than normal stature it is frequently desirable to be able to adjust the seat at various heights with respect to the back. Accordingly, in the modification shown in Figures 8 and 9 an arrangement has been made which may be adjusted so that the seat I6 may take any desired height relation with respect to the back I 8. According to this modification a seat frame I00 is provided with side bars I02 and I04 which are rigidly attached to a portion of the frame I00 by means of a clamp bar I06. The seat I6 is then mounted on the top of extension rods I08 substantially similar to the extension rods 40. However, the extension rods I00 are completely smooth and the locking arrangement is provided by means of locking bars I I0 and I I2 which extend igidly between the shoes I I4 and I I6 and the seat I 6. The bars IIO and H2 are provided with a plurality of openings I20 for engagement with the locking mechanism. The locking mechanism provides a base plate I22 extending across the side bars I02 and I04 substantially intermediate the extension rods I08. The latch mechanism comprises a rectangular frame I24 slidably mounted on the member I22. The frame I24 i provided with cross members I26 and I28 to which is rigidly attached keeper bars I 30 and I32. Keeper bar I30 is slidably engaged in a guide I34 while the keeper I32 is slidably engaged in a guide I36. A spring I38 is connected to the plate I22 and to the rectangular sliding frame I24 so that the frame I24 is resiliently biased into locking position.

In the operation of this modification the frame I24 is moved backward against the influence of the spring I38 and locked in position by means of a latch I40 mounted on the frame I24 and engaging a detent I42, the latch I40 having a cutout portion I44 for engaging the detent I42. The chair is then raised and the base collar rotated so that it is under the shoes H4 and I I6 after which the frame is lowered to any desired height then the latch I40 is raised so that the spring will bring the keepers I30 and I 32 into contact with the bars I I0 and I I2 so that they will engage one of the openings I20 therein. It will thus be seen that the chair seat can be adjusted to any desired position by means of the detents I30 and I32 engaging the openings I20 of the bars H0 and H2.

In the modification according to Figures 10' and 11 a locking mechanism is provided in the form of a sliding bar I50 mounted on brackets I52 attached to the side bars I02 and I04 preferably by means of the lock nuts I54 which secure tubular guides I56 in the side bars I02 and I04. The bar I50 is slidable on the brackets I52 by means of the slot I58 and is provided with key hole slots :ltii which selectively engage any of the reduced portions ifir. of the locking bar its.

Gbviously the extension rods 188 could be replaced by slide rods He having a plurality of reducedpcrtions It while locking bars [it simi lar to the locking bars 52 can be used to selectively lock the extension rods its at any desired height, as shown in Figure 12.

An improved base collar indicated generally at iilil may be constructed by two pairs of angle irons secured together. A pair of long irons 82 and HM are arranged in substantially fixed relation with a pair of short angle irons 536 and its. Preferably they are arranged in rectangular formation and held in adjusted position by means of bolts Isl! and 1&2. Obviously, this improved base plate may be turned so that the ends of the long angles extend transversely to the paths of travel in the path of travel of the shoes lit. Likewise, it can be rotated so that the short members are in the direction of travel so that the shoes lid may travel past the base collar.

While for the purposes of exempliflcation particular embodiments of the invention have been shown and described according to the best present understanding thereof, it will be apparent that changes and modifications can be made therein without departing from the true spirit of the invention.
