PATENT oFFlCE SIDNEY STERLING, OF LOS ANGELES, CALIFORNIA.

PORTABLE BARBER S CHAIR.

Application led November l80, 1925. Serial No. 72,322.

My invention relates generally to chairs, and particularly, although not necessarily, to barbers chairs.

Itis a purpose of my invention to rovide 6 a relatively simple, inexpensive and u rable barbers chair which is particularly designed `for use in hotels, clubhouses and the like, in that it is capable of being readily rolled over the floor to permit of its being moved to the room of the customer, yet when occupied to be incapable of movement and to support the occupant in any posltion 1n which the conventional stationary barbers chair is capable of supporting an occupant. It is also a purpose of my invention. to provide a portable barbers chair .having back and leg supporting means adJustable to support anv occupant in various recllned positions, and the two means bem'g oper- N atively connected so that when one or the other is adjusted a corresponding adjustment of the other means is concurrently effected. Y

I will describe only one form of barbers IS chair embodying my invention and will then point out the novel features thereof 1n the claim.

ln the drawings Figure 1 is a view showing in vertical section, and artly in elevation, one form of portable bar ers chair embodying my invention;

Figure 2 is a fragmentary vertical sectional view of the leg and foot supporting :5 members showing the other postion of the foot supporting means which means is capable of occupying;

Fioure 3 is a view similar to Figure 1, showing the chair in folded position;

Figure 4 is a horizontal sectional view taken on the line 4 4 of Figure 1;

Figures 5 and 6 are fragmentary views showing in side elevation one of the legs of the chair shown in the preceding views, the two positions which it is capable of occupying and the wheel supporting axle in section and in the two 'corresponding positions which it occupies;

Figure 7 is a detail perspective view of one of the leg sleeves shown in Figures 5 and 6;

Figures 8 and 9 are fragmentary views showing in rear elevation the two rear legs of the chair, the wheels, and the two positions which the wheels occupy to elevate orv .upper frame18. The upper frame serves to support a seat cushion 19, and the

legs

15 and 16 extend above the frame 18 to provide supports for arm rests 20.

vSecured on the lower ends of the two rear legs 16 are metallic sleeves 21 having their confronting sides formed with J-shaped slots 22 in which work the ends of an axle 23 on which latter are supported a pair oi:

wheels 24, preferably provided with rubber tires 25.v By reference to Figures 5, 6, 8 and 9, it will be seen that the axle 23 is capable of occupying the two extreme positions, one in which it is elevated to the upper ends of the slots 22, as in Figure 5, and the other in which its ends are disposed in the lower ends of the slots 22, as shown in Figure 6. In the rst extreme position of the axle the wheels 24 are elevated so as to allow the lower ends of the legs 16 to have contact with the floor and to thus co-operate with the front legs 15 in supporting the chair as a unit against movement on the Hoor. In the other extreme position the wheels 24 are lowered so that their peripheries are disposed below the lower ends of the legs 16, thereby operating to elevate the legs and support such legs for rolling movement. It is to be noted that with the wheels in lowered position the ends of the axle 23 are retained against accidental displacement from the lower end of the slots 22 by virtue of the abrupt curvature of the slots. With the wheels in lowered position, it will be manifest that by tilting theA chair so that the front legs are lifted out of contact with the licor, the entire chair can be easily rolled from place to place. To lower the legs 16 into contact with the ioor, when desiring to render the chair stationary, it is only necessary to kick the wheels downwardly and rearwardly, so as to remove the ends of the rest 28. A pair of bars 29 are secured to the moved to an inner sides of the

legs

15 and 16 so as to occupy inclined positions, and with their rear ends projecting from the rear legs 16 and providlng a pivotal mountingfor a pair of arms 30 secured tothe back 26 and constituting the back frame. These .arms 30 are fulcrumed on the bars 29 at the points indicated at 31 so that the back rest can be inclined position. The back carries an a justable head rest 32 mounted to swing on ears 33, as will `be understood.

The leg rest 27 is secured to a pair of arms 34 which constitute the leg rest frame, and such arms are pivoted at the oints indicated at 35 to the forward ends o the bars 29 so as to permit of the desired adjustment of the leg rest. A pair of relatively long links 36 are pivoted at their forward ends to the arms34 as indicated at 37, while at their rear ends they are `pivotally connected to the lower ends of the arms 30 at the points indicated at 38. These links 36 function to provide an operative connection between the ack rest and leg rest so that when one le frame or back frame is moved the other wi l be moved in the o posite direction. For example, whenthe sack frame is moved from the osition. shown in Figure 1 to that shown in igure 3, the leg frame will be swung downwardly from the position shown in Figure 1 to that shown in Figure 3. It will thus be seen that through the medium of the links 36 the back and leg frames are operatively connected to occupy the correct respectivepositions when either frame is adusted so that an occupant of the chair will e properly supported in reclining or upright positlon.

To secure the back and leg frames in adjusted position a pair of levers 38 are pivoted to the bars 29 at the points indicated at 40 and rigidly connected at their lower ends by means of a rod 41. The lower portions of the levers 39 are notched at intervals, as indicated at 42, for engagement with a rod 43 secured to and rigidly connecting the arms 30. The levers 39 are capable of being elevated to disengage the rod 43 or lowered to `engage the same by the manual manipulation of a crank 44 (Figure 4) secured to the end of a shaft 45 rotatably mounted in the arms 29. Fixed to the shaft 45, medially of its ends, is an 'arm 47 connected to a rod 48 through a link 49. The rod rigidly -connects the two levers 39, and it will be understood that by rotation of the shaft 45 through the medium of the crank 44 the two levers 39 can be lowered of elevated to engage or disengage the rod 43.

In the elevated position of the levers 39 the back and leg frames are free to be moved to any adjusted position, but when the levers are lowered so that the 'rod 43 engages within one of the notches 42 the arms 30 are locked against pivotal movement, thereby locking the arms 34 against similar movement and thereby securing the back and leg rests in adjusted position. j As shown in Figures 1 and 2, the arms 34 converge-toward their forward ends and provide means for pivotally supporting the 'foot rest 28. This foot rest 28 is of L- shaped form and is provided with a pair of L-shaped brackets 50 connecting reversely disposed '

lips

51 and 52. Thebrackets 50 are pivoted on the arms 34 at the point indicated at 53 so that they may be swung from the position shown in Figure 1 to that shown in Figure 2. In the first position ofthe brackets the lips 51 engage the upper edges of the arms to support the foot rest in horizontal position, while inthe second position the lips 52 engage the lower edges of the arms 34 and thus support the foot rest in vertical position. In the horizontal position of the foot rest the short arm is disposed in a right angular position with respect to the leg rest, while in the vertical position of the vfoot rest the other arm thereof isdisposed in right angularl position with respect to the leg rest. By virtue of the mounting of the` foot rest, it will be manifest that in the position-shown in Figure 1 it co-operates with the leg rest to accommodate legs of greater length than when in the position shown in Figure 2 so that it may be said that the foot rest is ad'ustable to accommodate and support legs o different lengths. This function is true of the foot rest when in horizontal or vertical position. v

In the horizontal position of the foot rest, it is secured against moving to vertical position by the provision of a latch 54 carried by the foot rest 28 and engaging the leg rest 27.

From the foregoing description, taken inconjunction with the accompanying drawings, it will be manifest that I have provided a barbers chair capable of accommodating and supporting persons in upright position or rcclnin g position as effectively as the conventional barber chair, and when the chair is not in use it can be readily moved from lace to place through the medium of the w eels 24. My invention is admirably adapted for use in hotels and clubhouses where it is highly desirable that the tonsorial operations be performed in the privacy of a customers room.

Although I` have herein shown and described onlyA one form of barbers chair emtov los

CFI

hodying my invention, it is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention and within the spirit and scope of the appended Claim.

I claim:

A. barbers chair comprising a chair body, bars secured to the body, a back rest frame fulcrumed on the bars, a leg rest frame pivoted on the bars, links pivotally connecting the two frames at the same side of their mountings, notched levers pivoted on the bars, a tie rod on the backrest frame, adaptkdisengage the rod,

ed'to engage within any one of the notches of said levers to secure the back rest frame in adjusted position, and manually operable means for moving the levers to engage or said manually operable means comprising a shaft, a crank on one end of the shaft, an arm fixed on the shaft, a tie rod connecting the levers, and a link connecting the tie rod and arm whereby, when the shaft is rotated, the two levers can be elevated and lowered to engage or disengage the rst rod.
