SPECIFICATION forming part of LettersPatent No. 524,853, dated August 1 21, 1894..

Application filed July 21, 1893- Serlal No. 481,141. (No model.) i

To all whom it may concern.-

Be it known thatI, WILLIAM G. HULLHORST,

of Toledo, county of Lucas, and State of Ohio, 1

have invented certain new and useful Improvements in Barbers Chairs; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of referencemarked thereon, which form part of this specification.

My invention relates to a barbers chair, and

has for its object to simplify the construction, I

cheapen the product, and produce a chair of greater convenience of manipulation than heretofore.

The invention consists in the parts and combination of parts hereinafter described, and pointed out in the claims.

In the drawings: Figure 1 is a side eleva tion of a complete chair. Fig.2, Sheet 2, is a longitudinal vertical section through the center of the chair. Fig. 3 is a detail view of a section of I the chair, showing, the automatic catch for supporting the head rest in adjusted position. Fig. 4 is a perspective view of the ratchet bar, showing the ratchet teeth and side flanges. Fig. 5 is a perspective of a section of the headrest, slide and pawl, showing the side plates which contact with the flanges. Fig. 6 is a detail front View of the chair showing the central slot in the standard, and the wood filling pieces.

1 designates the base, into. which a standard 2 is j ournaled, the upper portion of the standard being secured to a plate 3" in a manner to revolve with the plate.

Standard 2 comprises a plate 4, with a solid upper and lower end, and for lightness preferably having an opening 5 transversely of the plate, and of a thickness to allow of forming a recess 6 extending through the front portion to receive a quadrant shaped segment 7 which is pivotally secured therein, there be ing an upwardly projecting arm 8, the curved bar 9 of thesegment having a plurality of marginal holes 10 to receive a catch 11, secured in a bar 12 pivotally attached to plate 3, and actuated by means of a hand lift 13 within convenient reach of the operator.

and advanced by means of the depression of a foot lever 19, whereby the bolt impinges against the collar 20 which is secured to the base. 7

21 designates the seat secured upon plate 3 having sides 22 of anypreferred ornamentation, and a back 23 pivotally connected with the sides to allow the back to swing from a vertical to an inclined position.

Centrally of the width of the back there is formed a longitudinal recess 24 having a ratchet bar 25 with inwardly projecting teeth,

the inclination of which is. upwardly, and

which is an angular pawl 29, pivoted to the plates at the angle, in a position to rock thereon, when a pull is made upon the upper end and withdraw the pawl end from the teeth upon bar 25.

Pawl 29 isactuated by means of a lever 30 pivoted in the angled end 31 of the head rest slide 26, the inner end being connected with a rod 32 which passes through web 27 and is connected with the upper end of pawl 29, whereby when the outer end of the lever 30 is depressed, the pawl is rocked upon its pivot, and the pawl end is withdrawn from engagement with the ratchet bar, and when pressure upon lever 30 is withdrawn, the pawl is urged into engagement with the ratchet bar by means of a spring 33 coiled around the rod, with its upper end bearing against the web, and the lower end against the upper end of formed a segmental plate 34' having a plurality of notches or recesses 35 upon its edge to receive a catch upon a spring bar 36 secured upon a head rest 37 pivotally secured upon plate 34, whereby the head rest may be adjusted in any desired position by raising the spring bar and withdrawing. the catch from ably formed with an ornamental upper endv 39, which projects above the pivot 40, and is connected upon each side with the back by means of a bar 41, pivotally secured to the back and side bar, and serving not only as an arm rest when properly upholstered, but to cause the side bars to move in unison with the back as it is moved from a vertical to any desired inclination with 'relation to the seat.

Secured upon the lower ends of the side bars are bars 42 of the foot rest, having a roller 43 journaled between the same, and articulated to fold inwardly for the purpose of transportation or cleaning around the chair.

The back and foot rest are locked in any desired adjustment by the engagement of catch 11 with segment 7 through the medium of the rod 44: connecting the arm 8 of the segment and the cross bars 45 secured between .the side bars of the foot rest.

In operation, to revolve the chair, the operator throws lever 19 toward the back of the chair, the lower end contacting with a pin 19' to limit its movement, and the bolt 16 is retracted from the collar, allowing the same to turn in the base. When the chair has been revolved the proper distance, the operator throws thelever 19 forward (which may be done with the foot) and the bolt 16 is advanced to engage with the collar 20. The

back and foot rest are adjusted in any desired adjustment by pulling upon hand lift 13, and withdrawing catch 11 from engagement with the segment 7, when, upon movingv the back, a corresponding movement is given to the foot rest, whereby the back may be readily moved to a vertical position, thereby throwing the foot rest to its lowest point to render it convenient for a person to enter the chair (rod 44 contacting with a projection 44: to limit the movement) and when seated, a pull upon the back to a desired inclination will adjust the foot rest accordingly, the hand lift being released, catch 11 engages with the teeth of segment 7,1ocking the back and foot rest in position, and since the weight of the person is borne upon the seat, this operation is accomplished without the necessity of carrying the weight of the occupant, and consequently without the necessity of exerting great force.

What I claim isr v 1. In a chair, a base, a standard revolubly mounted thereon, a seat carried by the standard, a foot rest pivoted to the frame work of the seat armrests pivotally connecting the back and an upper extensionof thefoot-rest, a longitudinal slot in the standard, a toothed segment pivoted therein at the-lower end, a rod pivotally connecting the segment to the foot rest a lug upon the standard above the segment, a catch for engagement with the segment secured in the lug, and a rod pivoted to the seat at one side and to a vertical hand-grip at the opposite side-of the seat, said-rod being connected to and operating the catch.

2. In a chair, a back formed with a central recess, and having a ratchet faced bar having'flanges upon each side of the ratchet, in combination with a tubular slide carrying a head rest and having an upper right angled end, and a lower squared end a pawl pivoted to the slide at the lower end of the same, a lever pivoted in the right angled end of the slide, and a rod connecting the pawl and lever and a spring upon the rod bearing against the end of the slide and one end of the pawl,

whereby the slide may be raised or lowered by grasping the right angled end'of the slide and depressing the lever.

In testimony that I claim the foregoing as my own I hereby affix my signature in presence of two witnesses.

WILLIAM G. HULLHORST.
