Letters Patent No. 90,834, dated June 1, 1869.
IMPROVEMENT IN.APPARATUS FOR FELLING- TREES.
The Schedule referred to in these Letters Patent and making part of the same.
To all lwhom/ tt may conce/11a:v`
Be it known that I, M. R. FORY, of the city, county,
ing upon a carriage, which is rendered adjustable in respect to a tree, as fullydescribed hereafter', so that the angers may be caused to penetrate the tree at any desired angle or point, with but little labor on the part of the operaton In order to enable others skilled in the art to make and use my invention, I will now proceed to describe its vconstruction and operation, reference being had to the accompanying drawing, which forms a part of this specication, and in which- Figure l is a sectional elevation of my improved tree-felling apparatus, and
Figure 2, a plan view.
A is a frame, of wood or iron, at the rear side of which, near the ends, are projections a a, with rounded faces, and, from the front edges of the iiame, project sh`tarp-pointed pins b b, for a purpose described hereat er.
'I hrongh openings in the frame, and in the projections a a, extend bars, or arms B B, the outer ends of which are bent inward, and sharpened; and on the inner endof each arm turns a nut, c, which bears against the rounded face of the adjacent projection a.
To the upper side of the frame A is secured a plate, C', whichr is adjustable on a bolt, e, extending from the frame into. a slot, 11in the plate; and, through lugs j f, on the plate C, extend guides, or bars D D, on the' inner end of each of which turns a nut, g.
On the guides D slides freely a carriage, E, in bearings on which turn a driving-shaft, F, and a series of spindles, G` G, the latter being parallel to the guides D, and provided with pinions t', which gear into each other.
To the spindles nearest the ends of the carriage are secured bevel-wheels h, which gear with similar wheels h on the driving-shaft F, the latter, in the present instance, being provided'with a crank-handle, m.
To the outer end of each guide D is connected an arm, I, which extends forward beyond the frame A, the end of each arm adjacent to the frame being bent inward, and sharpened.
In the inner end of each spindle C is a socket, for the reception of the shank of an auger, J.-
When a tree, x, is to be felled, the frame A is placed against the trunk, its`pins b b piercing the same, as shown in tig. 1, and the sharpened hooked ends of the arms B B I I are driven into the tree, so as to hold the frame and the guides D D irmly in their positions, the plate C being parallelto the edge of the frame A, and the carriage E being drawn back to the outer ends of the guides.
A rotary motion is now imparted to the shaft F, and the carriage is pushed forward, so as to bring the angers against the tree, which they will perforate, borl ing a series of .parallel openings.
After the angers have passed through the tree, the carriage is drawn back, and the plate O is moved laterally until the angers are opposite `uncut portions of the tree, when the carriage is again moved forward, and another series of holes are bored, parallel to and between those first ont.
The 'apparatus is then detached, whena few blows 4 the angers, at the second operation, to penetrate the tree at an angle to the openings first made. j
Owing to the manner in which the angers are geared together, the adjaent angers' revolve in opposite direotions, and a straight cnt is thus insured, the angers of course being twisted to the right or to the left, according to the direction in which they turn.
Should the apparatus become unsteady from any cause, it may be secured firmly in its position by turning the nuts c g, and it will be seen that, inasmuch as the faces of the projections a u are rounded, the nuts c will have lirm bearings, whatever may be the position to which the arms B B are turned.
In order to guide the angers near theirffront ends,
they may be passed loosely through openings in a strip,
Y, arranged adjacentto thetree, to which it may be n secured temporarily.
In place of the arms B B, a chain, or yoke, extending round the tree, and attached to the frame A,l so as to be tightened at pleasure, may be used, andthe outer ends of the guides D may be secured to a frame adjustable upon a standard resting on the ground'.
A handle may be secured to eachend of the shaft F, or a .driving-pulley may be substituted for the han.- dle when steam or other power is used for 'operating the apparatus.
Without confining myself to the precise construction and arrangement of parts shown anddescribed, or to the use of angers of any special number, or size,
I claim as my invention, and desire to secure by Letters Patent-A 1. The combination and arrangement of the frame y A, guides D D, and carriage F, holding a series vof angers, all as and for the purpose specified.
2..'lhe arrangement of the adjustable arms I I, having hooked ends, and hung to the guides D D, as and for the purpose specified.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
M. It. FORY.

A. FRANKLIN, OWEN DOUGHERTY..
