ADJUSTABLE BARBER-CHAIR SEAT Filed July 9, 1950 2 Sheets-Sheet l Invcnlor A ilomey ADJUSTABLE BARBER CHAIR SEAT Filed July 9, 1930 2 Sheets-Sheet 2 Invenlor A llomey Patented Dec. 27, 1932 UNETED STATES PATENT OFFICE RUDOLPH NAGEL, OF MIAMI OKLAHOMA ADJUSTABLE BARBER- CHAIR SEAT- Application filed July 9, 1930. Serial No; 466,851.

provide a seat and actuating means therefor whereby the seat may be adjusted to an elevated position with ease and with quickness of execution.

These and numerous other important objects and advantages of the invention will readily become apparent to the reader of the following specification and claim.

In the drawings Figure 1 represents a side elevational view of a barber chair with the seat raised to an elevated position by the novel adjusting means.

Fig. 2 represents a horizontal sectional view through the chair construction beneath the seat to disclose the construction of the raising mechanism.

Fig. 3 represents an elevational view of the seat engaging bar.

Fig. 4 represents a fragmentary elevational view of the usual hydraulic control lever which is employed for actuating the raising mechanism.

Fig. 5 represents the handle for moving the engaging bar to an inoperative position.

Fig. 6 represents a fragmentary sectional view disclosing the manner of connecting the foot member to the shaft.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 represents the usual pedestal within which the piston 6 slides and supports the seat base 7, upon which the seat 8 normally rests.

In the present case, the seat 8 has a plurality of guide rods 9 extending therefrom and slidable through openings in the seat base 7 which keeps the seat from tipping when in elevated position.

Numeral 10 represents the usual arm rest while numeral 11 represents the back of the chair.

Numeral 12 represents the usual hand lever for controlling the hydraulic mechanism of the chair, and in the present instance, the

shaft 13 to which this hand lever connects, is equipped with a cam: member 14.

As is clearly shown in Fig. 2, the seat base 7 slidab'iy supports the shaft 15 in a pair of bearings 1616, this shaft 15 being reduced from one end as at 17 for disposition within the openings at one end of the foot member 18. A set screw 19 serves to secure this arouate shaped foot member 18 to the shaft 15.

A suitably formed handle 20 extends from the free end of the foot member 18 in a position accessible to the barber.

A bar 21 is connected to the shaft 15 by the connector 22, so that the bar 21 will swing with the shaft 15.

t can now be seen that the shaft 15 is both slidable and rotatable and by pulling or pushing on the handle 20, this shaft 15 can be moved inwardly or outwardly for disposition over or out of the path of the cam 14. Due

to the vertical disposition of the cam 14, when the seat is in elevated position, and the offset engagement of the foot 18 against the same, the bar 21 will be maintained elevated to sustain the weight of a person on the seat.

(See Fig. 1.) The handle 20 may be swingably connected to said foot 18, so that the same can be swung to avoid the lever 12 when the latter is being operated. This cam is a conventional part of the usual hydraulic mechanism of a barbers chair, the cam serving for engaging the usual release valve for permitting descent of the chair.

When the foot 18 is out of the path of the cam 14, the lever 12 may be operated without any effect on the seat raising mechanism. However, when the handle 20 is operated to place the foot 18 above and in the path of the cam 14, an upward movement of the handle 12 will result in the locking of the shaft 9O 15 and a consequential pressure of the bar 21 against the underside of the seat 8 so as to elevate the seat to the position shown in Fig. 1.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having thus described my invention, what I claim as new is In a barber chair having a seat and including a chair elevating control hand lever and a cam operated by said lever, a seat elevating mechanism comprising a shaft on the chair, an oflset cranked foot member carried by the shaft, a bar for engagement against the bottom side of the seat, and means rigidly con necting the bar and the shaft and means rotatably and slidably mounting said shaft on the chair whereby said shaft may be moved to dispose the foot in the path of the cam, and be thereby rotated to tilt said bar about the shaft as an axis and raise the seat vertically. In testimony whereof I afiiX my signature.

' V RUDOLPH NAGEL.
