Ueficd SW68 Pa TERMINAL, CORNER AND SPLICE CONNECTORS FOR ORNANIENTAL RAIL STRUCTURES This invention relates to new and useful improvements in terminal, corner, and splice connectors for use onornamental rail structures, and it is among the objects thereof to provide simple and efiicient connector means for joining flat, round and other shaped terminals to the end of hand rails and to splice such rails and corners with the fastening and splicing means that do not show after the parts have been assembled;

It is still a further object of the invention to provide simple and eflicient means for fastening balusters or rail posts to rails by such splice connectors.

It is still a further object of the invention to provide a simple means for splicing the rail sections, rail terminals, corner terminals and the like by the use of attaching means which operate to move and bias the fastened members into abutting engagement.

These and other objects of the invention will become more apparent from a' consideration of the accompany ing drawings constituting apart hereof in which like reference characters designate like parts, and in which:

In reference to Figures 1 to 3 of the drawing, the numeral 1 designates the end of an ornamental hand rail and 2, a rail terminal. The terminal 2 is provided with a T-shaped body portion 3 adapted to cooperate with the T slot 4 of the rail 1. The T-shaped body portion 3 may be integrally formed with or securely fastened to the terminal 2. The terminal is provided with drilled holes 5 for receiving pins 6 which are in alignment with and fit the drilled holes 5 in the rail 1. The T-shaped 2,873,095 ,Patented Feb. 10, 19 59 body portion} is provided with

tappedholes

8 and 9 which are at an angle, as shown, for receiving grub screws 10.

When'the terminal .2 is assembled with its T-shaped body portion 3 projected into the T slot 4 and the pins 6 in the openings 5, the screws 10 are threaded into

openings

8 and 9 and are. drawnup by means of a wrench or screwdriver, (not shown), the ends of thescrews having slots or recesses for receiving the bit of a screwdriver or anAllen'wren ch, by means ofwhich they are drawn tightin' theirlthreaded'bores and when they come through the top face ofthe T,-,shaped body portion 3, they will engage the upper wall of the T- slot 4 of the rail andeifect a displacement action cof the terminal 2 in the direction to produceclamping pressure on abutting faces 7 and 71; of; the rail 1 and terminal 2 to hold them securely-in their assembled position, as shown in Figura 2. INHH; Jay? I In the form'o f rail terminal shown in Figures 4 and :5, a round or tubular rail 11 having a split wall 12 is provided with a, 'fljslot 13 for receivinga T-shaped key 14, the latter being provided with ,a threaded hole 15 for receiving a setscrew '16. The railterminal 17 is provided with a segment-shaped tongue or projection 17a integral 1y formed with the terminal and fitted into the tubular chamber of the cylindrical rail'11 in the manner shown in Figure 5 of the drawing When the parts. are assembled, as shown in Figure 5,'the screw'16 is drawn up to effect displacement .ofl the, key, 14 with its fiange resting upon the shoulder of the split walllZ, as shown in Figure 5, and, with the. end of se tscr ew 16 engaging the segment-shaped tonguefpfltr the'terminal 17 and sere y 199 12 ea ii skzo Li I 1 v V In the matter of joining corners, as shown in Figure 10, rail portions 19 and 20 are mitered at 21 and 22 and are provided with T slots 4 for receiving T-shaped angles 23. The angles have threaded

screw holes

24 and 25 and 26 and 27, which screw holes are on a slant or angle in the manner of the

holes

8 and 9 of Figure l, the holes 24 and 25 being disposed at an angle to force the rail portion 20 upward, as viewed in the drawing, and the screw holes 26 and 27 being slanted at an angle like the

screw holes

8 and 9 in Figure l to force the rail portion 19 to the left, as viewed in the drawing. In this manner, the mitered ends 21 and 22 of the rails are forced into abutting engagement under pressure.

A splicing member and mounting bracket is shown in Figures 6, 7, 8 and 9, and consists of a one-piece T- shaped member 29 having projecting

ends

30 and 31, the member 29 being provided with a depending ear-shaped member 30a split by a saw cut, as shown at 32, the saw cut extending all the way down the ear 30a. By means of a setscrew 33, split portions of the car 3011 may be spread to form legs 34 of Figure 9.

The member 29 may be attached to the ends of rails (not shown) by inserting the T-shaped ends into T slots of the rails and may be secured thereto by means of screws 35 and 36, which are disposed at opposite angles to cause the spliced rail members to be biased towards each other in abutting engagement.

A curved end 37 of a baluster may be fastened to the legs 34 of the bracket by means of a threaded cap screw 38 extending through openings 39 of the legs 34 in the manner shown in Figure 8. j

Still another form of splicing and mounting bracket is shown in Figures ll, 12 and 13.

It consists of a T-shaped bar 40 having a slot 41 for receiving L -shaped members, the

legs

42 and 43 of which extend through the slots 41 and the L-

shaped ends

42a and 43a of which rest in a recessed portion 44 of the bar 40.

The bar 40 is provided with countersunk screw holes 3 45 and screw holes 46', the latter being slanted, as shown in Figure 13. Also, the bar 40 is preferably slit, as shown at 47, by means of a cutting saw to allow spreading of theTbar. g When assembled in the, manner shownin Figure 13, screws 48' and 49 are drawn up in the threaded openings 46 to cause the rail ends to draw together, as hereinbefore explained. Thefillister -headed sts'crews 50 are then extended through the countersunk holes 45 and exp'and the slitted portion of the rails. A baluster 51 may be attached to the L-

shaped rrrembers

42 and 43 in a manner similar to that shown iri'Fig'ure' 8 of the drawing.

It is evident from the description of Figures 6, 11' and 13 of the drawing, that the splice bars r'nay be split to yieldingly engage the T-s'l'ots' inlifh 'railpdrtions and increase the clamping action of the connector to produce a very secure splice withfthe abiiitting ends of the rails in clamping engagement; p i
