PHOTOGRAPHER S CHAIR.

To all whom t may concern:

Be it known that l, CLIFTON E. HERMAN, a citizen o-f the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in a Photographers Chair; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

rllhis invention relates to improvements in j hotographei"s chairs.

The objectof the invention is to provide a chair of this character having' an improved construction and arrangement of adjustable ba-ck and head rest, and means whereby said parts are supported to permit the same to be swung' aroundto the different positions on the seat or body portion of the chair.

Vith this and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be more fully de scribed and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1, is a side view constructed in accordance with my invention and showing in full lines one position of the chair back and head rest, and in dotted lines, showing the same parts adjusted to a different position. Fig. 2, is a plan view of the same, showing the back supporting mechanism and back rest in full lines in one position and in dotted lines showing the same swung around to another position. Fig. 3, is a perspective view of the pivotally mounted bracket for the back restsupporting bar. Fig. el, is a rear view of the adjustable back and head rest arranged thereon. Fig. 5, is an enlarged detail view of the clamping device for adjustably securing the head rest to the supporting bar. Fig. 6, is a detail view of the head rest and the upper end of its supporting rod; and, Fig. 7, is a detail fragmentary view of a portion of the back supporting bracket and the back rest bar, showing the manner in which the bar is raised and lowered in said bracket.

Referring more particularly to the drawings, 1, denotes the body or seat portion of the chair, said seat portion comprising supporting' legs 2, connected together by suitable braces 3, and arranged on a base or Specification of Letters Patent.

platform L1, having a foot rest 5, and being provided with suitable rollers G, whereby the chair may be readily pushed from one place to another.

Pivotally mounted in suitable cross braces 7, of the seat frame is a backsupporting bracket 8, said bracket comprising a pivot bar 9, the upper and lower ends of which are pivotally mounted in the cross braces 7, as shown. On the pivot bar 9, adjacent to its opposite ends are rigidly secured rearwardly projecting right angular formed arms or bars 10 and 11. The bars 10 and 11 are secured together by a brace bar 12. On the outer end of the bar 10 is arranged a bifurcated rack 13, on the outer end of which is formed a guide loop 14:, whichpconnects the outer ends of the bifurcated rack 13, and is provided for a purpose hereinafter described. On the outeil end of the lower bar 11, is formed a forked extension 15, in which is arranged a cross bar 16.

Arranged in the bifurcated rack 13, on the outer end of the bar 10, and engaged with the extension 15, on the bar 11, is a back rest supporting bar 17, said bar having a forked or bifurcated lower end 18, which is adapted to slidably engage the cross bar 16, in the extension 15, whereby the lower end of the bar is held in position. On the bar 17, is formed a series of laterally projecting supporting' pins 19, which are adapted to be engaged with the teeth of the rack 13, to hold the back supporting bar 17, at the desired elevation and angle. Then it is desired to raise or lower the bar 17 in the rack 13, said bar is raised slidably until the pin which enw gages the rack isclear of the teeth thereon after which the bar is swung back into the guide loop 141, at which time the bar may be readily lifted to the desired elevation and again swung over to permit the proper pins to engage the teeth of the rack. The guide loop 14, being of greater width than the space between the forked members of the rack will permit the pins on the bar to readily pass through the loop, as shown in Fig. 7 of the drawings. On the upper end of the bar 17, are formed apertured lugs 20, between which is pivotally mounted the shank 21, of a back rest 22, said rest being rigidly clamped at the desired angle by a clamping nut 23, which is screwed on at the threaded end of the pivot bolt which secures the shank 21, to the lugs 20.- In the upper portion of the bar 17, is formed a vertically disposed slot 24, in which is adjustably secured the lower end of a head rest supporting bar 25, on the upper end of which is arranged a head rest 26, said rest being provided with a rearwardly projecting apertured shank 27, which is pivotally mounted on the apertured upper end of the bar 25, by a pivot bolt 28, on which is arranged a clamping nut 29, whereby the head rest 26, is secured in adjusted positions on its supporting bar.

The lower end of the head rest supporting bar 25, is provided with a right-angularly disposed attaching and clamping device 30, comprising a stationary clamping plate 31, a connecting bolt 32, adapted to be inserted through the slot 24, of the supporting bar 25, and having a threaded outer end. On the bolt 32, is arranged an adjustable clamping plate 33, and on the threaded outer end of the bolt 32, is arranged a clamping nut 34, adapted to be screwed up into engagement with the clamping plate 33, whereby the latter is forced intotight engagement with the side of the supporting bar 25, thus securing the head rest in its adjusted position on the supporting bar.

By pivotally connecting the supporting bracket 8, to the cross bars 7, of the frame 2, said bracket may be swung laterally in one direction or the other at the back of the chair seat, thereby bringin the back and head rest to the desired posltion when the bracket has been thus swung in any suitable manner.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as defined in the appended claims.

Having thus described my invention, what I claim is:

l. In a chair of the character described, a seat supporting frame, a seat arranged thereon, a back supporting bracket pivotally mounted in said seat supporting frame, said bracket having a back adjusting rack and a forked extension, a back supporting bar having arranged therein a series of supporting pins to engage said rack, and a bifurcated lower end to engage the forked extension of said bracket.

2. In a photographers chair, the wheeled base, a seat supporting frame arranged thereon, a seat secured to said frame, a back supporting bracket pivotally mounted in said frame, said bracket having upper and lower rearwardly projecting supporting bars, a bifurcated rack on the outer end of said upper bar, a forked extension ou the outer end of said lower bar, said extension having a cross bar arranged therein, a back supporting bar slidably mounted in said bifurcated rack and having a bifurcated lower end to slidably engage the cross bar of the forked extension of said lower supporting bar, a series of supporting pins arranged on said supporting bar and adapted .to be engaged with said rack to hold the bar in its adjusted positions, means on said rack to permit the bar to be raised and lowered therein, a back rest and a head rest adj uslably secured to said back supporting bar.

3. In a photographers chair, a base, a seat supporting frame mounted thereon, a back supporting bracket pivotally mounted in said frame, said bracket having upper and lower rearwardly projecting supporting members, a bifurcated rack on the outer end of the upper supporting member of said bracket, a forked extension on the outer end of the lower member of the bracket, a cross bar or pin in the forked extension, a back supporting bar slidably mounted in said bifurcated rack and having a slotted lower end to slidably engage the cross bar or pin of said forked extension, a series of supporting pins arranged on said seat supporting bar and adapted to be engaged with said rack, whereby said bar may be held at the proper vertical adjustment and inclination, and a back rest pivoted to the upper end of said back supporting bar.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

CLIFTON E. HERMAN.
