MACHINE FOR ERECTING FRAME STRUCTURES.

sPnorFIcATIoN forming part of Letters fatent No. 530,028, dated November 27, 1 894. Application filed September 13, 1894. Serial No. 522,911. (No model.)

To all whom it may concern..-

Be it known that LJOSIAH FAIRBANK, a citizen of the United States of America, residing at Helena,in the county of Sandusky and State of Ohio,have invented certain new and useful Improvements in Machines for Erecting Frame Structures; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of my invention is to provide a cheap and effective apparatus for erecting the frames and boots of structures in place of the usual method of raising them by the ordinary cranes and tackle; and it consists in providing an upright which is so connected to the base frame that the angle thereof may be changed, a Windlass which is adjustable upon the base frame and extension rods, as will be hereinafter fully set forth and particularly pointed out in the claim.

In the accompanying drawings forming part of this specification, Figure 1 is a perspective view showing a machine for erecting frame structures as arranged for use in hoisting or positioning the beams or uprights of a frame building. Fig. 2 is a sectional view, and Fig. 3-is 'a detail view of the upper end of the uprights showing the arrangement of the pulleys thereon. Y

A designates the base frame to which the frame B is adapted to be secured by means of bolts and nuts I) as shown. The frame B consists of two longitudinal beams which are suitably connected to .each other by crossbeams, and near the forward end of the frame are attached upwardly-projecting plates B to which the side pieces of the upright O are pivotally connected. The side pieces of the upright are connected to each other by crosspieces as shown and at their upper ends are provided supports for pulleys c and o, the support for the pulleys 0 being braced by a plate 0 which depends from the upper crosspiece. Near the upper end of one of the side pieces of the upright is attached an eye 0 and at a suitable distance below this eye is secured a cleat 0 for the purpose hereinafter set forth.

D D designate brace-rods which are attached at one end to the rear end of the frame B and at the other to the upper ends of the upright O, as shown in Fig. 1, said brace-rods being extended to position the upright at a different inclination by interposing short sections D between the upper ends of said rods and the upright, as shown in Fig. 2.

The brace rods D I) which are removably connected to the pivoted upright and to the frame B can not only be varied as to length but may be dispensed with when the device is used for certain purposes. For instance it may be desirable to let the upper end of the pivoted bars bear against a structure when it is desired to elevate beams, &c., to a part of the structure which is less than its height.

E designates the frame of a Windlass which is mounted on the frame B so that it can be 7 adjusted longitudinally thereon,- the said frame being provided with a threaded bolte with which a nut e engages for clamping the frame E in an adjusted position upon the frame B, the Windlass being longitudinally .adj ustable to change the position of the same as the inclination of the upright is varied. In lifting heavy weights, and when the upright 0 is in nearly a vertical position, it is desirable to secure the Windlass to the frame B adjacent to the plates B or foot of the upright so that the rope which passes to the Windlass will not have a tendency to pull upon the upright so as to shift its position, and the greater the inclination of the upright the farther from the foot of the same the Windlass should be placed. From the shaft or drum of the Windlass extends a rope F which passes therefrom over the pulley c to and around one of the pulleys of a triple sheave G, from said sheave to and around one of the pulleys of back to the sheave around the center pulley therein to the other pulley 0 extending again to the sheave around the remaining pulley therein from which it extends to and through the eye 0 to the cleat c. The sheave G is provided with a suitable eye or ring to which the beam or bent is made fast in any suitable manner. The end of the beam is adapted to abut against the frameA in raising it from a horizontal to a vertical position.

In erecting the bouts of frame buildings two of the machines hereinbefore described are used.

The machine when not in use may be folded for convenience in transportation.

In use the machine is set either upon the ground, a sill of the building or upon the frame where the building has been partially erected, and it will be noted that the angle of the upright may be varied so that when the machine rests upon the beam, plates may be elevated without the use of other attachments.

I am aware that prior to my invention a patent was issued to Summit R. King, No. 207,746, dated September 3, 1878, for a machine which is designed to be used for the same purpose as this invention, but the construction of that device is radicallydifferent from mine, and I make no claim upon what is shown therein.

In a machine for use in erecting" the frames of buildings, the combination, of a base frame A and frame B connected thereto, an upright O pivotally connected to the frame B and having pulleys c and c c journaled in the upper end thereof, brace-rods D connected to the frame B and upright and having extensions D, an eye a and a cleat a secured to one of the side pieces of the upright, together with a Windlass E mounted on the frame B and means for adjusting said Windlass lengthwise of the frame, and a rope F which extends from the Windlass around the pulleys c and c and around a sheave through the eye 0 to the cleat c described and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOSIAH FAIRBANK.
