DAVID MAXWELL, OF PARIS, ONTARIO, CANADA.

HARVESTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 256,151, dated April 11, 1882.

Application filed August 29, 1881.

To all whom it may concern:

Be it known that I, DAVID MAXWELL, of the town of Paris, in the county of Brant, in the Province of Ontario, Canada, have invented new and useful Improvements in Harvestin g-Machines, of which the following is a specification.

The object of the invention is to brace the finger-beam on its top side at, the point where the rake-standard is carried; and it consists essentially of a bar or red attached at one end to the fingerbeam, near'the post or inner end of the beam, and at its other endto a bracket situated upon and attached to the finger-beam at a point near the rake-standard, the said rod being provided with suitable adjusting mechanism arranged to exert through the rod a pushing strain upon the two points connecting it to the finger-beam, substantially as hereinafter explained.

The drawings represent a sectional elevation of a portion of the finger-beam, showing the rake-standard and the post for connecting the beam to the main frame of the machine.

Figure 1 shows the bracing-rod connected at one end to the finger-beam by a bolt passing therethrough, from whence the brace extends obliquelyin an upward direction,through a passage-way made in the rake-standard, to a bracket bolted on the fingerbeam outside of the rake-standard. Fig. 2 is a similar view, showing the bracing-rod connected at one end on the bottom end of the post, below the fingerbeam, and extending obliquely in an upward direction to a bracket situated on the outside of the rake-standard. Fig. 3 shows two rods, one on each side of the rake-standard, running parallel with the finger-beam and connected'at either end to brackets, one situated near the inner end of the finger-beam and the other outside of the rake-standard.

I have shown my brace applied in three different ways. There are, of course, other ways of attaching the brace for accomplishing the same purpose; but the plans illustrated will be sufficient to explain the invention. The important point to be observed in arranging the brace is to see that the inner end of the rod is situated above the finger-beam.

Heretofore it has been customary to brace the finger-beam by a brace extending along its (No model.)

bottom. This brace is not only constantly vin the way, comingin contact with obstructions on the ground, but it does not effectually support the finger-beam at the point where it usually sags-viz., at the point where the rakestandard is situated.

A is the finger-beam; B, the post for connecting the beam to the main frame of the machine. O is the brace for staying the post B. D is the rakestandard. E is the bar or red forming my brace. F is a bracket situated outside of the rake-standard and provided with a socket, a, into which the end of the brace fits. G is a bolt passing through the finger-beam for securing the bracing-rod when arranged as shown in Fig. 1. H is a bracket situated on the inside of the finger-beam when the brace is to be arranged as shown in Fig. 3. I is a nut screwed upon the end of the brace E at the point-where it enters the bracket F.

When the bracing-rodE is placed in position the nut I is screwed against the bracket F, proor their exact location, except that the end of the bracing-rod near the rake-standard shall be above the fin ger-bcam.

I may also state that while it will be necessary, inorder to secure the full benefit of my invention, that the outer end of the rod E shall be connected to the finger-beam at a point outsideof the rake-standard,the same eifect would, in a measure, be secured by connecting it close to the rake-standard, even if it did not extend beyond it.

In the foregoing description I have referred to the brace as designed to support the weight of the rake-standard. In addition to accomplishing this object, the same brace may be utilized to strengthen the finger-beam to resist an upward strain, which object may be effected by extending the end of the rod E through the bracket F and placing upon the rod, on the outside of the bracket, an additional nut, I, as shown in Fig. 2.

What I claim as my invention is 1. In a harvesting-machine, the combination, with the finger-beam, of a bar or rod connected at one end to the finger-beam, near the post or inner end of the beam, and at its other in an upward direction to a point above the fingerbeam and near the rake standard, at which point it is adjust-ably connected to the finger-beam, in combination with means, substantially as described, by which a pushing strain can be exerted through the rod upon the two points connecting it to the finger-beain for the purpose of bracing thelatter at the point where the rake-standard is carried.

3. In a harvesting-machine, in combination with the finger-beam, a bar or rod secured above said finger-beam, and means, substantially as described,for exerting a pushing strain on said bar or rod for the purpose of bracing the finger-beam, substantially as specified.

4. In a harvesting'machine, a bar or rod rigidly attached to the inner end of the fingerbeam, and extending therefrom to a bracket attached to the finger-beam outside of the rakestandard, in combination with nuts I and I, screwed upon the rod and arranged to jam against the bracket F, substantially as and for the purpose specified.

DAVID MAXWELL.
