ROPE GRIP Filed July 15, 1926 W/ VHO all Patented June 7, 1927.
UNITED STATES ANDREW LUOIBELLO, OF NEW HAVEN, CONNECTICUT.
ROPE
Application filed July 15,
Fig. 1 is a side view of a rope clamp constructed in accordance with my invention; and i Fig. 2 is an edge view ofthe same.
This invention relates to improvement n rope-grips particularly adapted for use 111 connection with scaft'oldings or tackles gen erally, where it is desirable to have means to hold the rope against movement 1n one direction, but free to move in the opposite direction, the object being to provide means by which the rope will be firmly gripped and readily released, and the invention consists in the construction as hereinafter described and particularly recited in the clalm.
In carrying out my invention, I employ a cross-piece 5 formed at opposite ends Wl'tll eyes 6 and 7, through which a rope may pass. Extending upward from the crosspiece is a longitudinally-slotted post 8 formed near its upper end with a stop9, and at its upper end with an eye 10. Mounted in the post, betweenthesides thereof, upon pin 11, is a three-armed rope-gu1de 12, and also pivotally mounted in the post, 111st below the stop 9 upon a pivot 13, 1s a latch let formed at its lower end with a block arranged to enter between two or the arms of the rope'guide 12, but free to swing clear of it.
The ends of the arms of the guide are grooved to receive the rope, and this guide turns as the rope is moved and the rope is gripped by direct pressure between one of the arms and the latch and the use of roll ers in the guide is avoided.
At the upper end the latch 14; is formed with a stop-shoulder 16 to engage with the stop 9 and with an outwardly-projecting releasing-arm 17, to which a cord 18 is attached. The latch is drawn to its locking position by a spring 19, one end of which is fixed to the latch and the other end to a pin 20 extending between two lugs 21 and 22 extending outward from the sides of thepost The cross-piece 5 may also be provided on its underside with a downwardly-extending eye 23, to which one end of a rope may be attached. A rope 24: extends upward through the eye 7 over the arms of the rope-guide 12 and downward through the eye 6, and in the normal position, the block 15 of the latch will stand between two of the GRIP.

arms, and tension upon the end 25 of the rope will cause one of the arms 26 to clamp the rope between that arm and the block 15.
The end 27 of the rope, however, can be pulled down, and in so pulling the block 15 is moved forward, as shown in broken lines in Fig. 1, and the rope is free to travel, and in traveling turns the rope-clamp. As soon as downward pull upon the end 27 is released, one of the arms will again clamp the rope between that, arm and the block. Should it bedesired to move the rope in the opposite direction, that is, to let the end 25 down, a pull upon the cord 18 will move the latch 14 out or. engagement with the rope, so that the rope will then be free to travel in either direction.
One advantage of using a three-armed rope-guide is that sufiicient space is provided between the arms to permit the use of a single device with varying sizes of rope, and the advantage of providing a crosspiece with eyes through which the rope passes is to always maintain the rope in line with the three-armed ropeguide. If these eyes are not present, the rope is quite liable to swing out of line with the arms and consequently become ammed.
I thus provide, in a very simple way, a rope-clamp which is positively effective in gripping a rope to prevent its moving in one direction, but leaving it perfectly free to be moved in the opposite direction.
I claim:
A rope-clamp, comprising a cross-arm formed at opposite ends with eyes, through which the rope passes, a slotted post extending. upward from said cross-arm and provided at its upper end with an eye and with a stop, a three-armed rope-guide rotatably mounted in said post, theends of the arms formed with notches, a latch mounted in said post above said guide and provided at its lower end with a block extending into the path of the arms of the guide, said latch formed at its upper end with a stop and with a releasing-arm extending outward therefrom, and a spring tending to draw the latch into the path of movement of one of the arms of the said guide.
In testimony whereof, I have signed this specification.
ANDREW LUOIBELLO.
