Specification forming part of Letters Patent No. 35,607, dated June 17,-l862.

To aZZ whom it, may concern.-

Be it knownthat I, R. T. HATHAWAY, of .New'Bedford, in the county of Bristol and State of Massachusetts, have invented a new and ImprovediMachine for Raising and Transporting Stones; and I] do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of.

this specification, in which Figure 1 is a side .view of my invention; Fig. 2, aplan ortop view of the same; Fig. 3, a front view .of a portion of the same.

Similar letters of reference indicate corresponding parts in the several figures.

' The object of this invention is to obtain .a machineby which stones may be raised from the earth and transported from place to place with great facility, and at the same time be perfectlystrong and durable, so as to resist the great strain to which it may be subjected in raising the stones, and to sustain them when raised.

, To enable thoseskilled in the art to fully understand and construct my invention, 1 will proceed, to describe it.

A represents a rectangular frame, which 'is mounted centrally on two wheels, B B, and provided witha draft-pole, C, at its front part.

To the back end of the frame A there are attached 'two short uprights, a a, the upper ends of which are connected by a cross-bar, b,

. and at the front end of the frame A there are two cross-bars, c c, with a space, d, between them to receive the tenons e'ot inclined struts ff, the lower ends of which aresecured firmly down on the cross-barsc c by keys 9, passin'g through the tenon's underneath the bars, as shown clearly in Fig. 1. Vertical keysh may also be driven down between the bars a c, the back parts of said keys being fittedin recesses i in the back bar a to prevent the outward lateral shifting of the struts." (See Fig. v2.) The lower ends of I the strutsare still further secured inposition by metal clips j, attached to. the front bar cand to the struts, as shown in all the figures. The upper ends of the struts ff areconnected to the upper ends of inclined struts k k by metal brackets 1, (shown in Fig; 1,) and the lower ends of the struts k k are connected centrally to the side pieces, at m, of the frame A, as follows: The armsnnof the wheels B Bpasshorizontally under the side pieces, m m, of thefram'e A, and are bent upward at their inner parts, as shown at 0, so as'to bear against theinuersides of the'struts k k, as shown in Fig. 3. The upper ends of the inner parts, 0, of the arms it pass through plates p, attached to the inner sides of the struts, and have screw-nuts g on them. At

the outer sides of the lower parts of thest-ruts there are vertical metal bars 1" r, the lower 'ends of which are perforated for the arms a n of the wheels to pass through, and the upper ends-of the barsr 1' pass through metal plates s ,3, attached to the outer sides of the strutsk, and have nutst on them. The back oriinner. parts, 0,-of thearms a a and the bars 1' r at the outer sidesof the struts are clamped firmly to the struts by clips D, which are each formed of two bars, a a. connected at their ends by screw-bolts o. By this arrangement the lower ends of the struts k k'are firmly attached to the side pieces, at m, of the frame A. The struts 7a 7a are supported at their'back sides by inclined struts w w, which are connected at their upper ends to the upper ends of the struts k k by metal brackets a a, the

lower ends of strntsiw being fittedton the cross;

bar b,and secured thereto by 'metal clips b.

This mode of constructing the framing of the ;machine renders it very strong and durable,

an essential feature'in a machine of this kind, where great strength is required with aslittlev weightas possible. The securing of the struts kit to the side pieces, mm, of the frame A, as shown, not Qn'ly fi'rmly connectssaid struts to the side pieces, m, but also secures the arms a to the framing and adds greatly tothestrength of the machine.

On the upper part of the framing there is placed a shaft, E, to which a hoisting-chain,

F, is attached, having hookso' at its lower end. The shaft E has a toothedwheel, d, at one end of it, and also a ratchet, e, the latter being in close contact with the former. The ratchet e, when the machine is at work, has a pawl, f, engaged with it. (See Fig. 1.)

G G are two shafts the bearings of which are attached, respectively, to the struts ff w 10. These shafts have each at one end a pinion, 9, on them, both of which gear into the wheel a. of shaft E. On the opposite ends of the shafts G G there are placed toothed wheels h, into which pinions t" on shafts H H may be made to gear when desired, or be thrown v out of gear by shoving the shafts H Hin their bearings, which are on the struts f w, The shafts H H are held in position to keep the wheels h by meansof buttons j, attached to the framing and bearing against collars It on the shafts H H. (See Fig. 2.) By this arrangement it will be seen that the shaft E may be operated from one or both shafts H H, ac cording to the power required to raise the stone. The chain Fis attached to the stone to be raised in any proper way, and when itis sufiiciently elevated it is'drawn to the spot where it is to be laid or deposited and lowered by disengaging the pawl f from the ratchet e,

the pawl being held in an outward position (Shown in Fig. 1.)

The struts 7a is, it will be seen, are directly over and in line with the arms n n, and the shaft E is in line with said struts, and the from the ratchet by means of a hook, l.

framing is designed to be balanced on the wheels, so that when the stone is elevated the team will not be subjected to any of its weight. pinions i both in gear or out of gear with the Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- I l. The combination of the bent wheel arms or axles n n and bars 1' r with the side pieces, on m, struts 70k, plates 83, and clips D D,'i'n the manner and for the purpose herein shown and described;

2. The arrangement together of the liftingshaft E and its gear-wheels in the center of the framing ff w 10 7c is, as herein shown and described, so that the gearing and the weight to be lifted will always be evenly balanced upon the wheels, asset forth.
