To (LZZ whmn it may concern;

Be it known that 1, AUGUST PERREY, a citizen of the United States, residing at Crook, in the county of Osage and State of Missouri, have invented certain new and useful 1mprovements in Machines for Felling Trees, of which the following is a specification.

This invention provides a machine having for its primary intent to fell trees and raze stumps by cutting them with a sawing action, the machine being of such formation as to admit of the saw being fed as the work progresses.

In its organization the machine comprises a guide-frame. which is relatively fixed, a sec ond frame vertically adjustable on the guideframe and directed in its movements thereby and provided with the cutting mechanism, a saw, means for feeding the saw to the work, and actuating mechanism for imparting movement to the saw and feed mechanism, said actuating mechanism being of such construction as to admit of the movable frame being readily adjusted to effect cutting of the trees, stumps, and the like at any elevation.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

Vhile the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which"- Figure 1 is a perspective view of the invention, showing it applied. Fig. 2 is a front elevation thereof. Fig. 3 is a section on the line a: m of Fig. 2.. Fig. 1 is a section on the line 4 1 of Fig. 2. Fig. 5 is a detail perspective view of the saw and connections, the

parts being separated. Fig. 6 is a detail perspective view of the saw and its advancing mechanism.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Inasmuchas the mechanism is intended for use in the field and is designed to be operated by means of a traction-engine, it is shown in this connection in the accompanying drawings. It is to be understood, however, that within the purview of the invention the mechand supported anism may be mounted in any manner and I operated in any convenient way.

The main or guide frame comprises uprights 1, braces 2, and connecting-bars 3. A shaft 4 is journaled at or near its ends in the uprights 1 and is provided with spur-wheels 5 for cooperation with rack-bars 6 to effect vertical adjustment of the movable frame provided with cutting mechanism. The shaft 4 may be operated in any manner and for convenience is shown provided with a crank 7 A framework projects outward from the upper portion of the guide-frame and comprises beams 8 and timbers 9, the latter extending parallel with the uppermost connecting-bar 3 upon an end portion of the beams 8.. A shaft 10 is journaled in bearings attached to the outer ends of the beams 8 and is adapted to receive the power expended for operating the mechanism and for this purpose is provided at one end with a band-pulley 11, which is connected by drive-belt 12 with a convenient portion of the traction-engine or other source of power. A bevel-gear 13 is fast to one end of the power-driven shaft 10 and is in mesh with a companion bevel-gear 14, journaled to an end portion of the overhanging framework. A vertical shaft 15 is slidable in the bevel-gear 1 1 and serves to transmit motion to the cutting mechanism mounted upon the movable frame. Stays 16 connect the beams 8 with the lowest bar 3 and serve to brace the stationary framework.

The movable frame comprises a vertical portion 17, horizontal beams 18, a guideframe 19, supported at or near its ends by the horizontal beams 18, and a structure at one end of. the guide-frame supporting a crank-shaft 20 and lever 21, the latter being connected by pitman 22 with the crank-shaft 20. The movable frame is directed in its vertical adjustments and held in place by means of the uprights 1, suitable interlocking means being provided between said uprights and the corresponding vertical members of the part 17. The rack-bars 6 are attached at their lower ends to the vertical portion 17 and mesh with the spur-wheels 5, fast to the shaft 4., and upon turning said shaft 4: the movable frame may be adjusted to the desired elevation. The usual ratchet-and-pawl mechanism cooperates with the shaft a to hold it and the movable frame in the required position. Braces 23 connect the vertical portion 17 with the guide-frame 19 and materially strengthen the movable frame.

A slide 24 is mounted in the guide-frame 19 and receives a rectilinear reciprocating movement and has link orpitman connection with the lower end of the lever21. Arms 25 project outward from the slide 24 and pass through slots 26 in the outer side of the guide-frame 19. The arms 25 support the reciprocating saw 27, which is provided at its ends with clamps 28, loosely mounted upon the arms 25 and having oppositely-extended guide-rods 29, mounted in bearing-blocks 30, slidably mounted in the horizontal beams 18. The bearing-blocks are held to the horizontal beam 18 in a n'lanner to admit of their free movement, yet prevent casual displacement. As shown, the horizontal beams 18 are grooved or channeled in their upper sides, said groove or channel being of wedge form in cross-section, and each of the bearing-blocks is provided with a dovetailed projection snugly titting said groove. Threaded rods or shafts 31, mounted upon the horizontal beams 18, have screw-thread connection with the respective bearing-blocks 30 and serve in the operation of the machine to advance said blocks and the saw to the work. ing-shaft 32, located adjacent to the foot of the vertical portion 17, is geared at or near each end to the respective threaded rods or shafts 31 to effect simultaneous rotation thereof. Bevel-gears 33, fast to the operating-shaft 32, are in mesh with companion bevel-gears 34, fast to the inner ends of the rods or shafts 31. The operating-shaft 32 may be actuated in any determined way so as to effect a positive feed of the saw when the machine is in operation. A spur-wheel 35, constituting adrive, is mounted upon the hori zontal portion of the movable frame and is in mesh with a spur-wheel 36, fast to the operating-shaft 32. Power may be applied to the spur-wheel 35 in any manner, and, as shown, a handle is fitted thereto to admit of imparting motion thereto by hand.

A mechanism constructed substantially as herein set forth may be mounted in any convenient way for operation in the field, and, as shown, it is attached to a traction-engine of usual type. hen it is required to fell a tree or raze a stump, the traction-engine is moved to a position to bring the saw in operative position with reference to the tree or stump to be cut. By operating the shaft f the rackbars 6 may be run up more or less so as to adjust the movable frame vertically to bring the saw 27 to the required elevation. Upon imparting movement to the shaft 10 the saw 27 will have imparted thereto a reciprocating movement. This is effected by means of the vertical shaft 15, which receives motion from An operat' the bevel-gear 1% and transmits the same to the crank-shaft 20 by means of bevel- gears 37 and 38, the former being fast to a projecting end of the crank-shaft 20. The shaft 15 moves vertically with the frame carrying the cutting mechanism and has motion imparted thereto at all positions by reason of its slidable interlocking connection with the bevelgear 14:. The shaft 15 is angular in cross-section and snugly [its within an opening of corresponding shape formed in the bevel-gear 14, whereby the two are caused to rotate together, while at the same time the shaft 15 is enabled to play freely through the bevel-gear in the vertical adjustment of the movable frame carrying the cutting mechanism. W'hile the saw is in operation, it may be advanced to the work by operating the shaft 32, which turns the threaded rods or shafts 31 constituting the feed members, whereby the bearing-blocks 30 are moved upon the beams 18 and advance the saw 27.

Having thus described the invention, what is claimed as new is 1. In combination, a reciprocating slide, arms projected therefrom, a cutter loosely mounted upon said arms and having oppositelyextended guides, bearings receiving said guides, and means for adjusting said bearings to effect positive feed of the cutter to its work.

2. In combination, a guide-frame having longitudinal slots, a slide mounted in said frame, arms projected from the slide and passing through the longitudinal slots of the guideframe, a cutter loosely mounted upon said arms, guides projected outward from the cutter, bearing-blocks receiving said guides, and supporting means and feed mechanism for the bearing-blocks, substantially as set forth.

3. In combination, a guide-frame, a movable frame, cooperating means between the two frames to effect vertical adjustment of the movable frame, a reciprocating slide, driving mechanism mounted upon the guide-frame, means for transmitting motion from the driving mechanism to said slide at all adjustments of the movable frame, a cutter movable with said slide, bearing-blocks, guides cooperating with the bearing-blocks and projected from opposite ends of the cutter, and a feed mechanism mounted upon the movable frame for advancing said bearing-blocks to positively feed the cutter to its work.

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