Referring in detail to `the drawings, the numeral 10 designates a hollow base which can be made of any suitable material, such as metal, and a yieldable or rubber pad 11 is mounted on the lower edge of the base 10, Figure 1. Positioned within the base 10 is` anoutlet box 12 which is adapted to be connected to a suitable e source of electrical energy by means of a wire or cord 114. Alsoarranged within the base 10 is a platform 15 which is supported by a bolt and nut assembly `16,` and the platform 15 provides a support for an electric motor 15 lywto a chair for `use `in barber shops, beauty parlors and `17. Driven by the motor 17 is a shaft 18 which has a gear 19 mounted thereon, and the gear 19 meshes with e a gear 20 which is mounted on an end of a shaft 21. A

worm 22 is'also arranged on the shaft 21, and the worm 22 meshes with teeth 23, Figure 5. Arranged within the upper portion of the base 10 is a casing 24 which includes a lower section 25 and an upper section 26, and these sections maybe detachably connected together by means of bolt and nut assemblies 27. The interior of the casing 24 is hollowed out to provide a chamber or compartment 28 in which is mounted a gear member 29, and the gear member 29 has the teeth` 23 thereon which mesh with the worm 22. The casing 24 depends n from a hub 30which may be formed integral with the upper portion of the base, Figure 4. A rst sleeve 31. of hollow cylindrical construction extends upwardly from the hub 30 and threadedly engages the hub for a purpose to be later described. A -vertically disposed screw member 32 extends through the sleeve 31 and the screw mem ber 32includes a threaded portion 33 which `threadedly engages `the gear `29 so that as the gear 29 is rotated,

`the screw member 32 will move vertically :along its axis.

Depending from the gear member 29 and secured thereto or formed integral therewith is a stem 34 which 31to limit upward movement of the sleeve 44.

`includes a lower `threaded portion 35, Figure 4. A nut 36-is arranged in` threaded engagement with. the.portion 35, and an arm 37 extends outwardly from the nut 36, there being a collar 38"mounted on the 'arm 37. A lug or ngerextends outwardly from the collar 38,`and a guide rod 39 depends from the casing24 and projects through the collar 38.` The lug 40 is mounted for "Inovement into and out of engagement with `a pair of screw fmembers141 and 42,! and the screw members 41 and -42 lead fromand serve to actuate or energize a conventional limit switch 43.

Telescopically or slidably mounted in the rst sleeve 31 is a second sleeve 44 which has a `shoulder `45on`its lower end for coaction `with a shoulder 51 on the sleeve A shoulder 46 projects inwardly from the upperf endof lthe sleeve 44,: and the shoulder 46 is adapted to -be abutted by a shoulder 48 on the lower end of` a sleeve 47 so `as `to limit upward movement of the sleeve 47. e A rod or pin 49 is positioned within the sleeve 47 and is secured thereto byl means of a key or pin 50, and the rod 49 is mounted onor formed integral with the upper end of the screwmember 32. t.

Rotatably mounted on the sleeve 31 is a sleeve 52, and extending outwardly and upwardly from the sleeve e 52 is a pair of angularly arranged arms 53, there being y 3 l rumposed on the pin 57, an 'W th'ecoil'spring 58"1 ris between the'pair ofears 56, Figure 7.

Thus, by placing one hand on th'eiontrol l f levr 163 and moving this lever 63,'l the bai- 62 canbe used to raise the pin 57 against the tension of.the'fcoi1"spring 7() `58 so that theV bottom of the pin 57 fwill clear the teeth 60 to permit rotation of the sleeve .52 lto the desiredposi- JlQtion.

Hmovement of the lifting screw 32 in the pinion 29 while t 1 this pinion'29 is stationary but this is of no consequence` "since the` screw 32 has more threads than actually required for the amount of adjustment necessary for the `seat and` this screw also has more threads which extend beyond the point at which the limit switch 43 cuts ot the @power to the driving motor 17 so that one` rotation of j the entire chair will not place the mechanism out of time.

This causes vertical j VConsidering nextthe tilting of the back rest 88. Assuming the back rest to be tilted fully back as indicated in Figure 4, one hand may be placed near the top quarter of the back rest` 88"and pressure applied forward while theother hand is placed on the handle of the back rest tilting lever 100 and force applied downward. This `automatically unlocks the backrest tilt controland permits the customer to be raised to an upright sitting posi- .tion. Conversely, pressure appliedupward on the handle j j r1000i? the tilting control lever will permit the customer `to lean back. This action is dampened andperfect control of thespeed of tilt can be regulated by the back rest tilt locking device shownin Figures 8-12.

. When the customer leans back against the back rest l pressure is applied-backward or counterclockwise on the supports or channels 89 by means of the brackets 90 "and therefore appliesa counterclockwise torque on the ferrule 111, and the ferrule 111 is solidly connected to l the adjacent channel 89. This lcounterclockwise torque ffcauses the spring 101 to wind` and since the spring 101 has been constructed to tit snugly to the shaft 54, it will f lockon the shaft, and since the spring 101 has an end seated snugly in the slot 102 inthe ferrule 111, the following'will occur. `It is to be further noted that the` shaft j" "54 is pinned to a collar shaped projection 112 by means of a` pin 113, Figure 3, so that the back rest 88 cannot be forced back by the customer.` Now, if pressureis applied Conversely, pressure from the hand applied downto the adjacent channel 89 and this causes the spring 101 to unwind or release its hold on the shaft 54 to cause the back'rest 88 to tilt forwardly. This procedure permits perfect control so that the operator can control the movements of the customer and the customer will not be moved too fast so that he will not be injured ormade uncomfortable.` y j Tilting of the back rest 88 will produce a longitudinal 1 motion to the connecting bars 80 which have the` arm ,res`t`s181 secured thereto so that the arm rests will move back and forth as shown by broken lines and solid lines j in Figure 1. The bars 76and 83 are pivotally connected to the bar 80 bythe bolts 79 and 84 and these bars are also pivotally connected to the lugs 75` at the bottom of `"the `seat 74 by means of bolts 78 and 85. Thus, the members 80 will move in a line parallel to the axis of 1the seat base.

` The levers or support members 76 extend downwardly and are curved so that their lower ends terminate at a point to receive or have connected thereto the foot rest 77, and the foot rest 77 may be covered with a suitable covering to prevent slippage of the feet of the occupant of the chair.

The head rest 93 is` connectedto the upper end of a bar 92 which is adjustably mounted in a bracket V94 and this head rest can be removed when the faerso `is tte- `ceive a shampoo, rinse or the like. t i Theswitch 95 can be operated by the foot desired.

In the present invention the seat adjusts independently of the back. While the `drawings illustrate `the`use of gears being driven bythe motor 17, itis to be understood that other types of drive can be utilized, as for example a V-belt, friction drive or chain and` sprocket drive can be used. `The motor is preferably a series wound with reverse polarity winding in the eld coils, `but any type of motor that will work can be used. The seat can be raised and lowered without changing the adjusted position of the back rest. The lever 63 controls rotation of Thus, the back 88 will remain immobile in its adjusted positions while the seat raises and lowers regardless of the angle ofthe back. The arm rests`81 always remain level and the rollers 72 travelin the rails 73.

It is to be understood that with the present invention the seat `can be elevated and lowered at an angle parallel to the back rest and at `any angle that the back rest may be positioned at the time of adjusting the seat. After the customer is seated on thecushion 74, and work is to be done which requires the customer to remain in an upright position, the operator places a hand on the handle 104 and forces the same downward. to cause the shoulder of the crescent shaped opening inthe bearing of the lever 100 to engage with the lug which lprojects and j depends from `the ferrule 111 to cause the ferrule 111 to rotate." This ferrule" 111 depends fromr and `is secured 4to the pillow block shaped plate which is bolted or welded to the tubular back rest support 89. Thus, downward l wardly on the operatinglever 100 will cause pressure to be applied to the ferrule 111 which is connected solidly Now, if a` customer wishes a facial or similar work performed, the operator merely places a hand on the control knob 67 and applies downward pressure on the knob while placing the other hand in a different position on" the chair so as to rotate the chair to a position away from the rinse basin and to a position convenient to the operator and adjoining work tables. `The pressure applied to the knob` 67 `causes thelever 63 to rock on the bolt 66 to apply an upward movement to the bolt 64 to lift the L-shaped t member 62 which lifts the lock pin 57 and overcomes` the t head rest 93 to rotate as a unit.

`spring 58 to cause the pin 57 to disengage fromthe openings in the locking ring 59. This permits the seat 74, as well as the back rest 88, foot rest 77, arm rests 81` and Now, reversing the procedure, pressure is applied upward on the handle 104 and this causes the lever 100 to raise. 'This rotates the ferrule 99 which depends from the lever 100 and this unwinds the spring 101 which is j wound tight on the fixed shaft `54. This permits the ferj tomer, to thereby prevent accidents caused by too rapid reclining or falling back and striking the head on rinse basins and the like. j

l To reposition the customer from this position to the rinse basin for shampoo and the like, the above procedure is reversed, whereby the customer is re-erected which also causes the arm rest 81 to move forward and upward but parallel to the seat 74, the arm rest 81 being pivotally mounted as at 83; The foot rest support 76 causes the foot rest 77 to retract and lower to a comfortable position while sittingerect. Conversely, when the backrest 88 is reclined,` the foot rest 77 is extended forward Iand to said back rest, connecting means mounted in said back rest, linkage means connecting the means in said back rest to said seat, an electric motor mounted in said base and connected to said second shaft for the rotation of said second shaft for raising and lowering said seat along a path parallel to the back rest and parallel to any plane in which the back rest may be positioned in at the time of adjusting the seat, and manually operable means for rotating said seat and back rest.
