TO `ALL WHOM I'l MAY CONCERN: i V

Be itvknown that I, JOHN S. HALL, of Jeieisonville, Clarke county, State of Indiana, have invented certain new and useful Improvements in Machines or Apparatus for 'Bending Cradle and Scythe-Smiths and other articles bent tortuouslyand I do hereby declare the following description and accompanying drawings are suicient to enable any person skilled in the artnr science to which it most nearly appertains to make and use my said invention or improvements without further invention or experiment.

l The nature of my' invention and improvements consists in a lexible strap, of a` peculiar construction, prov vided with sockets, and used in combination with a mould or former for bending cradle and Scythe-smiths, and in providing the sockets in the straps with latches.

In the accompanying drawings- Figure 1 is a plan of a strap with my improvements.

Figure 2 is an edge view of the strap applied to a stick ready for bending.

Figure 3 is a'. mould to bend the stick on.

Figure 4 shows the stick and strap on the mould bent in a proper form fora cradle or Scythe-snath.

AIn these drawings, A A are the centre links of thestrap, made of plate or sheet metal, and connected by the rivet B, with their extremities fastenedto the sockets C and D, which sockets are made of thick sheet metal, in the form shown, or in such other form as will answer'. the purpose, and fastened to the links A A by rivets.

n The space in the socket C is made large enugh to receive the snath'E, and provided with alatch, F, which swings on a rivet in the socket and catches under the head of the screw .Gr in the pposite end of the socket, whenfthe latch is swung over the snath to hold it in the socket.

' The link-H is fastened to the socket C, and connected to the link Hlby the rivet H?, forming a hinge betweeii the links, to permit the strap tobend edgewise when desired; and the endvoiI link Hl is fastened to the hook I, which is made in the form shown, to receive the large end of the snath to be bent, and may be provided with a screw, to act against the end ofthe sncth, if desired.

' The socket D is made to receive the snath, and provided with a latch, J, which swings across the socket the snath, to hold it in, and latches under the screw J in the socket, to hold the snath in while it is being bent. The socket D has the link K fastened to it, which is connected to the link K1 by the rivet K2, so that the strap may bend edgewise as well as ilatwisc. The link K1 has the hook L fastened to it, to receive the small end of the snath, and hold it while itis being'bent.

s This hook may also l-be provided with a screw, to act against the end of thc wood, if preferred that way.

The mould or formP, iig. 3, may be made ot' wrought or east iron, in the form shown, with two iianges at the large end, a flange, M, on one'side in the centre, and a flange, N, near the small end.

The snath-sticksfare turned the form and size required, and steamed, and the straps applied to them, when they are bent to the mould by means oi` a rope, crank, and levers, and a clamp, applied to the small end to hold it te the mould until it is cooled and dried or set, when it may be released, and another putin its place.

Instead of sockets with latches, rings may be used by pushing the snaths inendways, and removing them inthe same way. I 'Having described my improvements in apparatus for. bending cradle and Scythe-snaths, I claim- The iexible strap, provided with sockets C and D, in c'ombination with the mould or former P, constructed and arranged to operateas set forth. 4

JOHN S. HALL.
