EoEE 0E WIEE CABLE LADDER.
Patented May 18, 1886.
(No Model.)
UNTTED STATES PATENT OFFICE.
CONRAD -JOSIJPII HEIDMEYER, OF ALLEGHENY, PENNSYLVANIA.
ROPE OR WIRE CABLE LADDER.
Application tiled July 20, 1885.
.To all whom, t may concern:
Be it known that I, CONRAD JOSEPH HEID- MEYER, of the city of Allegheny, county of Alleghen y, State of Pennsylvania, have invented new and useful Improvements in Flexible Ladders; and I do hereby declare that the following is a full,clear,and exact description ofthe same, reference heilig had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.
Figures l, 2, 3, and L are sectional views of the detached rope ladder.
This invention consists in the novel way to securely fasten a rundle or step to the upright ropes or wire cables that form the sides of a ladder.
The process of manufacture is as follows: 1 is an ordinary rope or wire cable of any desired thickness, depending on the strength of the ladder to be manufactured.
2 is a mal leableiron casting, commonly called a T, the opening for the rope in the same cast to iit any desired size of rope or wire cable, the connecting opening or outlet having a right-hand thread tapped thereinto correspond with the thread cut on the end ofthe rundle or step ofthe ladder, the cylindrical part of this casting directly back of the outlet being eut away, leaving a ring extending around the top and bottom toclasp the rope or wire cable, the part eut away being for the purpose of giving the rope or wire cable room to expand on being forced apart by the tapered pointed rundle, also to give free access of air to the same in case the rope should get wet, also to keep t-he rope exposed to View, thereby preventing any accident which might result from the rope becoming worn out inside of a T having no part of it cutaway, where a rope, should it become worn out, would be unseen and unknown to the person operating or using the ladder.
4 is a casting similar' to 2, having a lefthaud thread tapped in the outlet to correspond with a left-hand thread eut on one end of the rundle or step of the ladder.
FICATON forming part of Letters Patent No. 342,204, dated May 18, 1886.
Serial No. 172,167. (No model.)
3 is the rundle or step of the ladder, and is an ordinary piece of iron pipe, usually about one-half inch in diameter and about fourteen inches long, having the ends plugged and welded with a short piece of iron to lill the openings.V The ends are then tapered down, each end having a smooth tapered point with the extreme end slightly rounded, so it may not cut the fibers of a rope when it enters the same. In addition to having each endtapered to a point each lend has a thread cut thereon to correspond with the threads tapped in the outlets of 2 and 4, pipe being used instead of solid round bar-iron ou account of it being much lighter and lnaking the ladder when finished more portable.
To forni the ladder have two ropes ot' any desired length, pa-ss the T having a right-hand thread tapped in the outlet over one rope, pass the T having a left -hand thread tapped in the outlet over the other rope, screw in the rundle or step, starting both threads on or about the saine time, and so continue on until any desired length of ladder is finished.
Having described this invention, what I claim, and desire to secu re by Letters Patent, 1s-
l. A ladder rundle orstep madeofsolid iron or a hollow piece of iron pipe having a right and left thread cut on opposite ends, each end heilig provided with a smooth tapered point, said ends being tapered for the purpose of entering between the strands of a rope or a wire cable, substantially as specified.
v 2. A malleable T-shaped irou with the cylyndrieal part back of the outlet cut away, leaving` a ring or band extending around the top and bottom, substantially as specified.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
CONRAD JOSEPH HEIIhllEYER.
