Description

the edges of the individual links are supported to unload the hinged joints, the protrusions 64, 65 and the edges of the links are set in such a way that the branches of the cep D (Fig. 1) form slightly convex curves. The middle links 68 ((1) I1 16-1)) have a wedge-shaped form at the back for clamping P1) and work between the plates of the leading uiiauia 4 (Fig. 9, 10), are cleaned by aubes 70 and have lugs 65 for abutting the edges of adjacent edges links (I, 62. BisenbH 61, 62 connect 11111 in pairs by a protrusion 64, on which the edges of links 63 and are put on each other by divorced cutting teeth GI), 67 and clean teeth 68 and 69. Teeth 68 and 69 are supplied in clean end 70 teeth of the middle link 63 so that they form one tooth of the triple thick. Some of the middle links 71 do not have teeth at all. In the variant, the 68 teeth (Figs. 13-15 and 20-25) are provided with middle links 63 only.

The frame With cocTOip from tubular arc 7, the internal cavity of which, separated by part 51 (Fig. 1), serves as a reservoir of oil. The end of the frame 7 is connected to the supporting part 31, and is bred by the cup 52 (FIG. 33) with a hole 53 provided with a spring closure through which the internal cavity of the pipe 7 can be filled with oil. An emitted crane 55 (FIG. 5) with a flexible toe 56 passes lubricant to the chain. The other end of the frame is mounted on the protrusion 5 of the casting 1, which carries the pilpy pulley 4 (Fig. 10) and is connected to the casting using a wedge joint (Fig. 11).

The support part 1 also carries a support device, made in the form of a wedge-shaped plate 23 with a serrated part 24 (Fig. 1), for grasping the tree and supporting the machine during the entire passage of the saw in the trunk. To prevent the saw from clamping in a tree, an expanding wedge 26 is provided, which is placed on the same flange of the support part 1 of the saw plane, between its two branches and advancing along the saw with the saw. Casting 1 is associated with castings 9 with castings (Figs. 1, 2), which carry handles 20, 21, 22 for supporting machine parts with a motor beam 11.

for protection of the worker at a rupture of a chain, and also against winding of having interrupted-shsys tseni on a pulley. A stiffening link 13 is attached to this beam 11, suspended by the other end to the ram suspension 15 (Fig. 6 or 7). When the saw machine is operating in different positions of the nrsdlopsp, the Primamatichskiy tank 1, rasnololsenny on the beam 11 (Fig. 1.) for the nitrate carburetor; 4. At the bottom of the tank there is a casting 5, to which a regulating mechanism 6 with two chambers 11 and 19 connected by channels 23 and 12 with a shut-off valve 14 is bolted. The fuel from the main tank entering chamber 11 through hole 9 passes through channels 12 and 13 to the carburetor. The chamber 19 has an atmosphere with a tube 27 in the lid 20 and with a chamber 26 in the upper part of the tank using the tube 25 above the fuel level; When the level in chamber 19 falls below line A (Fig. 31), outside air must flow through pipes 27 and 25 into the tank and increase the flow of fuel. The action of the saw machine consists in placing it with the help of the handle 46, 20, 21 and 22 (Fig. 1) in the burn ;-( ontal position to the sawn trunk so that the wedge plate 23 with its serrated part touches the tree. After starting the engine, remove The chain D is also a tension tool B in the pulley 4, which achieves the movement of the saw and its operation. Then the saw is evenly distributed before the end of the cut so that the wedge plate 23 moves along the surface of the tree and the unclamping wedge enters the sawn. stop the chain.

The subject of the patent.

1. A motor machine with a chain saw consisting of a power unit driving a power unit associated with one of the parts connected to one another by an arcuate frame of parts supporting the saw pulleys, the other of which carries a device that is tensioned to the saw what is in it

The driving pulley 4 (Fig. 1, 2) is composed of two conical plates 28, 30 and 29, 30 (Fig. 9, 10), of which the plate 28, 30 is wedged on the motor shaft 3, and the plate 29, 30 and the gear it can be loosely II can have an axial movement, driven by a lash pulley 38 (fig. 1, 2, 3, 4), also made in the form of two conical plates, but with each other rigidly (fig. 3), worn j freely on an axis 37 skrenked with a toothed rack 41-42, moved, for the purpose of tensioning the saw, in the part 31 supporting for the pulley 38 by means of the toothed sector 43 and the lever 44 with a pinch lock.

2. Alteration of the machine described in paragraph 1, characterized in that, for tensioning the saw, instead of a rack transfer, a screw gear 41, 42 (Fig. 33, 34) is used, controlled by the handle 43.

3.B described in pp. 1 and 2 machine tools the use of a valuable saw (Fig. 16-19), composed of three groups of links, of which middle links 63 from the side, o, drawn to the pulleys, have, for the purpose of clamping, the work between the plates 28, 29 (Fng. 9, 10) of the driving pulley, a wedge-shaped form, is provided with 70 / l teeth provided with: on the sides of the projections 65 to rest the corresponding edges of the side groups of the links 61, 62, and on the ends of the edges, capable of leaning on the protrusions 64, connecting each pair of opposite links 61, 62, each provided respectively displaced with respect to other divorced cutting teeth 66, 67 and clean teeth 68, 69, which together with the same tooth 70 of the corresponding middle link are placed against each other, and some of the middle links 71 may not have teeth, but the projections 64, 65 and their corresponding edges on the links x are so outlined on the surfaces that are in contact with each other, so that the branches of the D chain (Fig. 1) form slightly convex curves, l

And, K.

4. Change of saw, characterized in n. 3, characterized in that the cleaning teeth 68 in. It (Figs. 13-15 and 20-28) are only on the bottom of the middle links.

5.B characterized p. 1 l 2 machine tools for changing the supporting equipment in the form of a parallel flat surface; nija spikes icji into the view of nlastlkp 28 (Fig.; 1, 2), Moiyincfl is equipped with; 1a;} wood and in contact with it all the time when feeding nila.

6.In described in p. 1 and 2 of the machine tool wedge 26 (fig. 1 and 2), the nominal between the saw in common with it is the average blade of the moving together with the saw in the blade.

7.B described in pp 1n 2 machines on the application.11 connection of on-line nonsupple pulleys of the arc-shaped frame C (fng. 1) in the form of a bent pipe 7, the cavity of which is used as a reservoir for oil supplied to the nile through associated with the pipe 7 oiler 52 (FNG. 4, 5).

8.In described in p. 1 and 2 machines on a nesui (she is the support of the support part for a leading jaw, filled with liquid fuel tank G (Fig. 1, 2, 29-32), equipped in the lower corner of the base with a tank with two chambers 11 and 19, The chamber 11, at the known position of the crane 14, can be communicated through the channels 12 and 13 with the carburetor for supplying fuel to it and simultaneously with the chamber 19. having a connection through the channel 2T with the atmosphere and equipped with a tube 25 opening into the chamber 26 (Fig. 2 and 32) in the upper part of the tank 1 above the level of the fuel filling it, What is the purpose of the tube 25 is to keep the fuel level in chamber 19 unaltered, and thereby regulate its supply to the carburetor.
