JAMES SPRUCE, OF WATERBURY, CONNECTICUT, ASSIGNOR TO THE SCOVILL MANUFACTURING COMPANY, OF SAME PLACE.

CURTAIN-POLE JOINT.

SPECIFICATION forming part of Letters Patent No. 327,834, dated October 6,1885.

Application filed Jnly27, 1885.

To aZZ whom it may concern:

Be it known that I, JAMES SPRUCE, of \Vaterbury, in the county of New Haven and State of Connecticut, have invented a new Improvement in Curtain-Pole Joints; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure l, a top view showing the two shanks screw-threaded and standing in diametrically opposite positions, broken lines at the right indicating different angles to which the shanks may be turned with relation to each other; Fig. 2, a side view of the same; Fig. 8, a horizontal section of the same; Fig. 4, a vertical central section of the opposite sides of the joints; Fig. 5, a modification of the construction of the outer shell.

This invention relates to an improvement in the connection between the parts of the pole employed over windows, from which curtains are suspended. The object of the joint is that a bend may be madein the pole-as for bay-windows or other points where the pole is required to be turned away from a direct line. To cut the pole and abut the joint, so as to make a good finish, is avery difficult and expensive operation. Again, such a cutting and fitting requires the work of a skilled mechanic, which in many places it is inconvenient to obtain. To overcome these difficulties a joint something in the character of a hinge has been provided, one part attached to one end of one part of the pole and the other part of the joint attached to the corresponding end of the adjacent part, and so that one part may be turned to any desirable angle to the other. This enables the cutting of the ends of the pole substantially square, and avoids the fitting and expensive work necessary to attain a good angle. It is to this peculiarity of joint that the invention particularly relates; and it consists in a shell, substantially circular in horizontal section, having a screw fixed at one pointlprojeoting radially therefrom, and in the said horizontal plane, and also constructed with a horizontal slot extending par- Serial No. 172,772. (No model.)

tially around the said shell opposite the said fixed screw, combined with a ring within said shell, having a second screw rigidly fixed to it and projecting radially therefrom through said horizontal slot, and in the same plane as the screw fixed to the shell, as more fully hereinafter described.

In the construction of the joint I prefer to make the shell in spherical form. A repre sents one part, and B the other part, of the shell; and I prefer to make the shell in three parts, C being the third part. This third part, C, is in the form of a ring, and the parts A B are attached to each edge of the ring, so that the three parts together form substantially a sphere, as seen in Fig. 2.

From the ring C a screw or equivalent shank, D, extends radially and in the diametrical plane of the ring or sphere. The screw is rigidly fixed to the ring, so that it becomes a permanent part of it. This may be done by inserting the screw through the ring and riveting it thereon, as indicated in Fig. 3; or it may be soldered or brazed thereto.

In the ring opposite the screw D a slot, E, is formed circumferentially, and in the same plane as the screw D, and it extends preferably about one-third of the circumference of the ring. Inside this ring or shell a ring, F, is arranged, so as to fit closely upon the inside of the shell, and guided thereby is permitted to rotate within the shell. To this shell a screw, G, is rigidly fixed, in like manner as is the screw D to the outer shell, the screw G extending radially from its ring and through the slot E in the shell or outer ring, and so that the two screws stand in the same plane, as seen in Fig. 2, the two screws being at right angles to the axis, about which the shell or ring may turn, the one upon the other. Preferably I make the inner ring complete,- and that it may not interfere with the inner end of the screw D, fixed in the shell, I construct the inner ring with a slot, H, in the same plane as the slot E in the outer shell, and so that in the movement of the shell upon the ring, or vice versa, the inner end of the screw will not interfere with the inner ring. This inner ring, however, need not extend entirely around the inside of the shell, it only eing necessary that it shall take a bearing ufficient in extent to support the ring against .iametrical thrust upon the screw G, fixed to t, or upon the screw D, fixed to the outer shell.

In the construction, as illustrated inFigs. 2, 3, and 4, the central portion, 0, has its .pper and lower edge turned outward, and

he corresponding edge of the parts A B are urned, respectively, over the projecting edge.

o the ring by soldering or otherwise. The

arts A B serve only as ornamental portions, s the outer ring, 0, and the inner ring, F, vith their respective fixed screws, make the onnection between the two parts of the pole.

The central portion, and to which the one crew D is fixed, may be made integral with be part A, as seen in Fig. 5, so that the shell omplete will be formed in two parts, instead f three, as before described; but I prefer to nake the central portion irrtwo rings, both lotted, the outer ring having the screw rigdly fixed to it, and the inner ring having a crewrigidly fixed to it, to work through the lot in the outer ring. By this construction he two screws are maintained in the same ilane.

In applying the joint, the screw or shank D 3 introduced into the end of one part of the ole and the screw G into the corresponding nd of the other part,- then the one part may be urned upon the other in either direction, as :rdicated in broken lines, Fig. 1, to bring it a the required angle.

The two parts A B, which practically form overs to close the ring, may be made of any esirable style or shape, giving to the joint more or less ornamentation according to the amount of work applied.

It will be understood from the foregoing that I do not claim, broadly, the ball-like joint between adjacent ends of the parts of a curtain-pole; but

What I do claim is 1. The Zherein-described joint for curtainpole, consisting of the outer ring or shell having a shank, D, rigidly fixed thereto and extending therefrom in a radial direction and in a horizontal plane, the shell constructed with a slot, E, opposite the fixed shank and in the same horizontal plane, combined with a ring, F, arranged within the shell and in the plane of the before-mentioned slot, the said inner ring having a shank, G, rigidly fixed thereto and extending radially therefrom through the said slot E in the outer shell, and in substanstantially the same plane as the shank- D of the shell, substantially as described.

2. The ring O,constructed with a rigid shank, D, projecting radially therefrom, the said ring constructed with a slot, E, opposite the said shank and in the plane of the ring, a ring, F, arranged within said ring 0, and adapted to freely turn therein in the plane of the ring, the said ring F, constructed with a rigid shank, G, projecting radially therefrom and through the said slot E in the ring 0, the two parts A B, attached to the respective edges of the ring 0 to substantially close the ring, substantially as described.
