GAS OR LAMP BRACKET.

SPECIFICATION forming part of Letters Patent No. 403,508, dated May 21, 1889.

Application filed May 15, 1888.

To a 10700722, it may concern.-

Be it known that we, VILLIAM BOEKEL and JULIUS BOEKEL, citizens of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvementin Gas or Lamp Brackets, which improvement is fully set forth in the following specification and accompany ing drawings.

Our invention consists of a gas or lamp bracket provided with a frictionjoint and means for adjusting the same, as will. be hereinafterfully set forth and specifically claimed.

Figures 1 and 5 represent side elevations of gas or lamp brackets embodying our inve11- tion. Figs. 2 and 6 represent top or plan views thereof. Fig. 3 represents a vertical section on line 0;,Fig. 1, on an enlarged scale. Fig. at represents a vertical section on line y y, Fig. l, on an enlarged scale. Fig. 7 represents a vertical section on line 2, Fig. 5, on an en larged scale. Fig. 8 represents a vertical section on line a a, Fig. 5, on an enlarged scale. Fig. 9 represents a horizontal section on line b b, Fig. 5, on an enlarged scale.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A, Sheet 1, represents a gas-fixture, consisting of the pipes B O. The pipe B is connected with the vertical post D, which has a bore therein, and is jointed to the plug-containing branch E of the fixture, so as to rotate thereon. The pipe B is connected with the post D by a horizontal joint, it being evident that gas is adapted to flow through the branch E and enter the bore of the post D, and thus reach the pipe B. (See Fig. 3.) At the end of the pipe B opposite to the post I) is a vertical post, F, which has a bore therein, said end of the pipe B being connected with the post D by a horizontalj oint.

To the lower end of the post F is connected the pipe C, the joint of said post and pipe being vertical, whereby the pipe is capable of lateral motions, it being seen that after the gas leaves the pipe 13 it enters the bore of the post F and so reaches the pipe 0, as clearly illustrated in Fig. 4, it also being noticed that the posts D and F are parallel.

G represents an arm, rod, or bar, which is parallel with the pipe B and has one end jointed. to the post D. The other end of said $eria1No.273,933- (No model.)

bar is secured to or formed with a disk, H, which is in contact with a disk, J, secured to the inner faces of the disks being serrated, having packing K interposed between them and forming a friction-joint.

M represents a belt, which is passed through a jam-nut, N, which tightens against the bar G, and is adapted to clamp the disks against each other.

It will be seen that the pipes 13 C may be and the burner directed in corresponding dircction.

By loosening the nut N the pipe 13 may be raised and lowered on its axis or joint on the and thereby vertically adjusting the burner. The nut is now tightened, whereby the disks H J are clamped together, thus preventing motion of the pipe B and connected parts,

In Sheet 2 the bar, rod, or arm B is substituted for the pipe 13. The pipe C may be a rod, if so desired, and is adapted for support ing a lamp at its outer end.

bracket E, and the pipe 0 is mounted on the center of the post F, said post F and the upper bar, G, being connected by a friction-joint formed by the disks H J, bolt M, and nut N,

that of the parts described in Sheet 1.

A laryngoscope or other device for surgical or other purposes may be supported on the lamp or burner on the pipe O, the adjustment having a connecting-bar5 but we are not aware that the specific combination of parts herein described and claimed is old.

Having thus described our inventiomwhat ters Patent, is----- The improved lamp or gas bracket herein described, consisting of a branch with a hori zontal opening in the same, the vertical post or formed with the upper end of the post F,

the disks H J and packing K and screws into moved laterally, similar to gas fixtures in use,

post D, thus raising or lowering the pipe C,

and consequently firmly sustain in g the fixture.

The post D centrally supported in the the operation of the parts being similar to of the fixture adapting the light to be directed connected with upright posts, the said posts 5 we claim as new, and desire to secure by Let- IOO D, rotatably connected with said branch, the parts being combined substantially as devertical posts F, with serrated disk J at-its scribed.
