FRANCIS E. TOTTEN, OF NEWARK, NEW JERSEY.

UNIVERSAL FRICTIONAL HINGE.

SPECIFICATION forming part of Letters Patent No. 763,220, dated June 21, 1904.

Application filed April 19, 1904.

To all whom it may concern:

Be it known that I, FRANCIs E. TOTTEN, a citizen of the United States, residing at N ewark, in the county of Essex and State of New Jersey, have invented certain new and useful Im provements in Universal Frictional Hinges; and I do hereby 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, reference being had to the accompanying drawings, and to numerals ofreference marked thereon, which form a part of this specification.

The objects of this invention are to secure a positive movement of parts in frictional relation in adjustable fixturessuch as mirrors, towel racks or bars, adjustable shelves, robehooks, brackets, and similar articles adapted to be secured upon the wall of a room or other fixture; to enable the desired adjustments of parts in frictional contact to be maintained with greater certainty and with such a friction as will hold the movable parts positively in position after adjustment; to avoid all use of set-screws or other hand-operable fixing devices such as will tend to impair the appearance of the device and render it more expensive, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved adjustable bracket or support for mirrors or other articles and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like numerals of reference indicate cor- .responding parts in each of the several figures,

. tion of the parts to any desired extent. said inner friction-tube 7 is preferably split,

Serial No. 203,842. (No model.)

has at its front two tubes or hollow cylinders 6 6, rigidly fixed thereon in axial alinement, but a little apart from one another, the said cylinders having therein a friction-tube 7, which extends from one fixed tube to the other, as shown in Fig. 2. Said friction-tube is at its opposite ends provided interiorly with threads 8, adapted to receive tapering or conical screws 10. Into the opposite ends of the friction-tube 7 are inserted the said conical screws 10, and when the latter are turned inward the ends of the friction-tube are forced into frictional contact with their respective outer cylinders 6, the screws expanding the saidends of the tube and increasing the fric- The as at 11, only part way'through its length and is rigidly fastened to the projecting head 12 of the bracket. The said projecting head is horizontally bored and through the boring is inserted the tube 7, the same being fastened intermediate of its split ends to said head by means of the pin or screw 13, which latter is inserted in the head and friction-tube provided with female threads for the purpose. Thus thehead and friction-tube work together and the friction-tube cannot move longitudinally except when the screw 13 is removed.

The forward end of the head 12, which is enlarged for the purpose, is vertically perforated, as at 1 1, to receive a friction-piece 15, which is split where it enters said head and is soldered or otherwise secured within the arm 16, to which a mirror-plate 17 or a shelf or other article or device is held in frictional contact. Said friction-piece 15 is fitted within the tubular arm 16 and soldered or similarly secured therein, and the split portion 18 is somewhat enlarged, so as to form a shoulder 19 to receive the end of the tube; but said end of the tube projects beyond said shoulder 19 to form a second shoulder 20 to engage the head 12. The arm 16 is thus in pivotal relation to the head, so as turn horizontally therein, and its pivotal movements are made easy or less easy by turning the conical screw 21 within the said threaded friction-piece. The

mirror-plate 17 is also provided with a head 24, vertically perforated to receive the vertical free extremity of the arm 16, which arm is preferably S shape, the said arm being provided at said free extremity with another split friction-piece 25 and conical screw 26 similar to those already described.

the construction described the mirror or the plate 17 can be turned vertically or horizontally, and the horizontal movements can be either on the center 25 or on the center 15. Should there be any undue looseness because of wear, such looseness can be readily taken up by means of the

screws

10, 22, or 26.

I am aware that various modifications of construction may be employed without departing from the spirit or scope of the invention, and I do not wish to be understood as limiting my self by the various descriptive terms hereinbefore employed, excepting as the state of the art may require. 7

Having thus described the invention, what I claim as new is- 1. The improved bracket or adjustable fixture herein described, the joints of which are provided with split friction-tubes in which are inserted conical screws adapted to expand the said friction-tubes to increase the friction, substantially as set forth.

2. The combination with a plate having two hollow cylinders fixed thereto in alinement, said cylinders being arranged apart, and having a projecting perforated head between, a friction-tube extending through said head and into said cylinders and conical screws extending oppositely into the opposite ends of said friction-piece, said head being perforated vertically at its projecting end, an arm having a split friction-piece lying in the vertical perforation and a conical screw holding it therein, and a plate pivoted at the free end of said arm, substantially as set forth.

3. The combination, in abracket, of a plate having two hollow cylinders in alinement with a space between, a friction-tube split at opposite ends and at its split ends lying in said hollow cylinders, and a head arranged between said cylinders on said arm, a screw holding said friction-tube in fixed relation to said head, said head serving as a support for an arm or other attachment, substantially as set forth.

4. The combination, in a bracket, of a plate having two hollow cylinders in'alinement with a space between, a friction-tube split at opposite ends and at its split ends lying in said cylinders, and a head arranged between said cylinders on said arm, a screw extending through the head into the friction-tube, the plate between said cylinders being open to permit the insertion and removal of said screw, said screw holding said friction-tube in fixed relation to said head, and said head serving as a support for an arm or other attachment, substantially as set forth.

In testimony that 1 claim the foregoing I have hereunto set my hand this 8th day of April, 1904:.

FRANCIS E. TOTTEN.
