1 Claim.

The present invention relates to new and useful improvements in twisting machines, and has for its primary object to provide, in a manner as hereinafter set forth, an apparatus of this character comprising a novel construction, combination and arrangement for separating the strands of a rope and twisting all of the separated strands simultaneously.

Another very important object of the invention is to provide a twisting machine of the aforementioned character which embodies unique means for maintaining the proper tension on the rope.

Other objects of the invention are to provide a twisting machine of the character described which will be comparatively simple in construction, strong, durable, highly efficient and reliale in use, and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanyingdrawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure l is a view in side elevation of a twisting apparatus constructed in accordance with the present invention.

Figure 2 is a view in front elevation of the twisting unit.

Figure 3 is a top plan view of the apparatus.

Figures 4 and 5 are cross sectional views, taken substantially on the line 44 and 55 of Figure 1.

Figure 6 is a view in longitudinal section, taken substantially on the line 66 of Figure 3.

Figure 7 is a view in longitudinal section, taken substantially on the line 1-1 of Figure 3.

Figure 8 is a view in vertical section through the twisting unit, taken substantially on the'line 8-5 of Figure 1.

Figure 9 is a View in horizontal section through the rope anchoring swivel.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises an elongated base which is designated generally by refprises an upstanding housing 23 havingjournaled therein'a main shaft 24 and a plurality-of erence numeral l. The base i includes a pair of v spaced, parallel side bars 2 of suitable material Blocks 6 and l are operable longitudinally in the base I between the side bars 2, said blockscomprising, respectively, side flanges or tongues 8 and 9 which are slidably engaged in the channels or grooves 3. Rising from the block 6 is a pin or the like It to which a swivel H is connected. The swivel ll constitutes means for anchoring one end of a length of rope, as at IE, to the block 6. A cable l3 has one end secured to the block 6. The cable is is trained around pulleys i l on the members and 5 and has suspended from its other end a weight I 5 for moving the slidable block 6 in a direction. to tension the rope l2.

Rising from the slidable block I is a forkdd which is engageable between thestrands I? of the rope l2 for separating said strands. l8 has one end connected to the block I. The cable I8 is trained around pulleys l9'which are provided therefor on the base I and the member 5 and has its other end connected to a weight 28 which is slidably mounted on an inclined rail 2| which extends between said member 5 and said base i. The cable i8 passes under the block 6.

Positioned adjacent the rear end of the base I is atwisting unit 22. The twisting unit 22 comationthereby. Hooks 3%! are fixed on the forward ends of the shafts 24 and for connecting the strands ll of the rope l2 to said shafts.

It is thought that the operation of the appa-" ratus will be readily apparent from a consideration of the foregoing. Briefly, one end of the rope l2 is connected to the swivel H on the block 6 and the strands I! are separated at the other end of said rope and secured to the hooks so. The fork it is then engaged between the separated rope strands. The shafts 24 and 25 are then rotated to twist the rope strands ll. As the strands H are twisted, the fork is is pulled toward the end of the rope l2 which is anchored to the blockli for progressively separating said strands. As hereinbefore explained, the weight I5 maintains the proper tension on the rope I2.

It is believed that the many advantages. of a twisting machine constructed in accordance with A cable A drive shaft 21from' the present invention will be readily understood, and although a preferred embodiment of the apparatus is as illustrated and described, it is to be understood that changes in the detail of construction and in the combination and arrangement of parts may be resorted to which will fall 7 within the scope of the invention as claimed.

What is claimed is:

A twisting machine of the character described comprising an elongated base including a pair of spaced, parallel side bars having longitudinal channels in their opposed sides, a pair of blocks operable between the side bars, said blocks including tongues slidablyengaged in the chan-- nels, means for connecting one end of a rope to one of the blocks, a fork on the other block engageable between the strands of the rope for separating said strands, a weight connected to said one block for tensioning the rope, a weight connected to said other block for moving the fork toward said one end of the rope for separating the strands, a housing, a plurality of shafts journaled in said housing, hooks on the shafts for connection with the rope strands for twisting same, and means for rotating the shafts.
