IMPROVED MACHINE FOR. RAISING AND TRANSPORTING STONES: p

Specification forming part of Letters Patent No. 12,666, dated April 10, 1855; Reissue No. 1,0770, dated November 6, 1860.

ing them; and I do hereby declare the samev to befully described in the following specification, and illustrated in the accompanying drawings, of which- Figure 1 is a perspective view of it. Fig. 2 is an elevation of its derrick, and exhibits the two separate wheel journals or axles and a section of the bed-frame upon which the derrick is supported. Fig. 3 is a top view of the said bed-frame and the auxiliary windlass Fig. 4 is a top view of the derrick braces or struts and the main windlass applied thereto. Fig. 5 is a front view of one of the iron or metallic braces by which the derrick, the bed-frame, and wheel axle or journal are secured together. Fig. 6 is an under-side view of one of the said journals or axles. i

The nature of my invention consists in an improved arrangement of derrick, open bedframe, and two separate wheel axles or journals also, in a combination and arrangement of an auxiliary windlass and its line pawl and ratchet, or mechanical equivalents therefor, with themain windlass, the crank-shaft, and their operating-gears.

In the drawings, A is the bed-frame, which consists of a strong rectangular frame constructed of two side timbers, a af, and three connecting-timbers, b c d," arranged as shown in Fig. 3, such frame being provided with a Itongue or pole, B, for the application of a span ofk horses or yoke of oxen to the machine.

A derrick, C, is elevated directly over the middle of the open space E, which is between the timbers c and d, the two posts or inclined timbers e e of such derrick, being stepped, respectively, in .the side timbers, a a', of the bed-frame.

Two wheel axles or journals, F F, are so arranged as to project in opposite directions from the bedframe in manner as shown in the drawings, their axes being in a vertical plane passing transversely across the bed-frame and through the middle of the derrick. Each of these' axles or journals receives one of two wheels, G G, such wheels being arranged with respect to the hedframe as shown in Fig. l.

The derrick is further supported on the bedframe by two struts or braces, H H, which` extend from the cross bar or timber b to the head or upper end of the derrick, and serve to support the boxes ff of the journals of the shaft of a windlass, I, below which `an auxiliary windlass, K, is arranged, the shaft L of the said auxiliary windlass being supported in boxes q g, bolted to and resting on the bedfram e. The auxiliary windlass revolves loosely on its shaft, and is provided with a pawl or click, h, which is extended from the bed-frame and plays into a ratchet, i, fixed on the end of the said windlass. A rope or line, l, is attached at one of its ends to the windlass, and after being wound several times around it is led forward along the tongue B, and thence downward through it at or near its front end, the said rope iu its passage through the tongue being supported against two sheaves or rollers, m n, arranged on the tongue. The rope, on being led from the tongue, may, when the machine is in use, have one or more draft-animals applied to it for the purpose of eiecting. draft on such rope in order to cause the auxiliary windlass to be rotated by the rope.

Besides two cranks, o o, affixed to its opposite ends, (see Fig. 3,) the shaft L carries a circular wheel or head, p, which is placed against one end of the auxiliary windlass. A bolt or pin, q, extends through the head p and into the windlass, and may be withdrawn from the two, as occasion may require. While in place, as described, such pin serves to so lock the windlass to the head p as to enable the former to be revolved by the shaft L, in order to wind the rope on the windlass. 4The ratchet i and pawl h are to prevent the rope from being unwound from the auxiliary windlass while the shaft L may be in the act of being revolved by men or operators acting on either or both of its cranks. L has a pinion-gear, s, affixed to it, such pinion being made to engage with a larger gear, f, fixed on the shaft of the main windlass I. A ratchet, u, is xed to the side of the gear t, and receives a pawl, e, extended from a pin, w, that projects from and extends through one Furthermore, the shaft f lass.

of the` Vstruts of the derrick. From the Win11-,

` in opposite sides of the stone.

rEhe arrangement of the dcrriok, the open bed-frame, and the two separate shafts or journals of the Wheels is peculiarly favorable for enabling the great strain or weight of a stone to besustained in a vertical plane passing directly through the middle of the derriek and the axes of the Wheels. Furthermore, the derrick constitutes an arch to brace the bedframe under the pressure of a load While the said frame is upheld by the Wheels and axles. The axles are separate, so that there is a clear space between them, they not being connected by any bar extending across the frame and directly under the derrick.

In operating with the machine, after it may have been brought over a stone and had its chain alixed thereto, Workmen are to lay hold of and turn the cranks of the auxiliary Wind- At the same time, if oxen or draft-animals are caused to draw on the line of such windlass, We thus, by such means, Will be enabled to exert in conjunction with the manual power, and for effecting the rotation of the main Windlass, an additional and superior force, the machine, by its peculiar construction, being able to raise out of theground or` from it a very massive stone, and subsequently to transport such stone to any required distance and deposit it in a Wall, or where it may be required to be placed.

After the stone may have been Yraised from its bed the rope may be 11e-coiled around the auxiliary Windlass.k n essary to unlock the Windlass from iis shaft and revolve such windlass by manual power.

I claiml.V My improved stone-carriage or arrangement of derrick C, open bed-frame A, and" two separate or disconnected Wheel axles or journals, substantially as specified.
