The sawing machine (Figs. 1 and 2) consists of a fixed quadrangular frame Ci, Cwi, € -2, Cg, on the horizontal parts of which the rollers p are reinforced, which serve to move the movable frame P along them, pivotally aligned in its upper beam the arm Pr, swivel mounted on bolt I in the vertex of a triangle formed by two inclined bars rigidly connected to the upper part of the fixed frame; The bolt g can be moved along the notch on the lever Pr under the influence of oscillatory forces applied to the upper end of the lever Pr, with fix and So cables and transmitted x. through the lower end of the same lever to the movable frame, thus receiving a reciprocating motion. The cable BI, which envelops the blocks Oj b, is connected to the end of the lever Pr2, which receives periodic oscillatory movements around the axis e under the influence of a series of kulaks l mounted on the impeller k, manually or in some other way driven.

The cable BZ, passing through block 62, is connected to the end of the lever Pr, also placed on the axis just next to the lever Pr2 and set in motion by another number of knobs l, on the impeller k. The saw ends are moving in the slots of the movable frame P 17, equipped with weights T, at which the entire saw can be lifted upward with a TS BRZ fastened in the middle of the saw. The log to be sawn is clamped by the spring compressions Szh and moves along the rollers Hk, fixed in the longitudinal bars of the RL, which are supported on. coasters yas.

The modified device (Fig. 6), intended for the longitudinal sawing of logs into bars, consists of two frames, of which the first device is similar to the above basic installation except for the device of two horizontally set saws, having the ability to move with their ends in cuts in the movable frame P In addition, the impeller acts on the swing arms Pr-2 and nps not with fists, but protrusions horizontally mounted on the rim of the wheel. The second frame (Fig. 1) consists of the fixed frame ai, chn, ck, cK-i, CKz, CK4, through the couplings m in the horizontal bars of which the IJtUji bar Pgi is connected, connected to the movable frame b. In the cuts in the movable frame, the ends of vertically mounted saws can be moved, receiving, together with frame 6, reciprocating movements B in the vertical direction under the action of Tpi and Tr2 cables thrown over the blocks of bl and bl2 and alternately receiving tension under the influence of the installation of the rocking arms fJpz and D & C and the impeller k, is similar to the first frame. Both machines, which serve for longitudinal sawing, have a device for feeding logs and receiving sawn material, consisting of a series of plt forms (Fig. 12), of which the first is: a) Langyu, the movement of the supplied is rigidly connected with the controversial rails and it can be moved in vertical directions with screwed rods (Fig. 14 and It) .. Subsequent platforms

at one end there are rollers D which rest on each previous platform, and on the other end are threaded rods with rollers p on the lower ends supported on the rails; thus, the platforms can be moved in both horizontal and vertical directions in order to give the axis of the log to be sawed a position parallel to the plane of movement of the horizontal saws. To receive the sawn material, an installation is intended (Figures 18, 19, and 20), consisting of a table with RLs, along which the sawn material can move; In front of the table, in the direction of movement of the material, the lower horizontal n. and lateral vertical knives HI and 2 are placed, which penetrate into the corresponding log of the log in order to separate the sawn timber from the rest of the log.

Under the influence of the periodic pressing of the protruding parts of the impeller to, swinging levers Ex., 1 and impart tension alternately to one or the other of the two ropes connected to the movable frame and, thus, transmit reciprocating movements connected to the movable frames, what, according to the author, it is assumed that when assembling a complete installation, all three types of machines are used, of which the first divides the supplied logs into segments of a given length, and the other two subject the log to subsequent edging four sides.

P | redmet patent.

1. A saw machine, characterized by the use of areas P (Figs 1 and 2), provided with longitudinal slits O on racks for moving them in order to feed the saw P carrying at the ends the weight T for pressing when feeding and connected to block by cable B for raising the saw to the upper position after reproducing each cut, what frame P gets return straight movements along the C 1 and Skz guides, using the envelopes associated with it at the top

blocks 6i and bocanals BI and B-, fastened respectively on the same side with the longitudinal slot Oi of the yoke Pr (Fig. 1), connected with the bolt 2 (Fig. 1 and 3) freely passed through the slot with the parts of the machine base SC, and on the other hand, with the ends of two Pr-Lrz rocker arms with a common axis e, the free ends of which are under the influence of the L and L fists on the LH flywheel (Figures 1, 4 and 5), which are rotated in one way or another to communicate reciprocating working movements of the saw P for sawing logs (figs. 1 and 2) supplied between the spring compressions hedgehog Yak on the rollers having an axis in the adjustable crossbars on the racks Ac Pn.

2. Modification of the machine described in p. 1 for the case of longitudinal sawing of logs to beams, characterized by using two frames instead of one saw frame or two, in the first of which (FIG. B) two adjustable height along slots are placed (FIG. 6.9 and 10) horizontal saws, and in the second, installed behind the first one (FIG. P), two similar vertical saws, which are adjustable in the lateral direction and placed. in frame b, guided by the cKj, CK2 bars of the fixed paradise c «i, cc, cci, cKi, and moved vertically with the help of Jltui bars, fluiz, from a mechanism similar to the same for the first frame.

3. In the machine tool described in paragraph 2, the use of a sawing-log supporting device consisting (Fig. 12, 20) of a row of platforms 1, 2, 3, of which the first is connected to the supporting rails rigidly and can only be moved upwards and down with screwed rods (Fig. 17), and the second and each of the following lies with one end of the rollers (Fig. 18) at the previous one, and at the other bears screwed rods (Fig. 16, 18) with rollers p at the lower ends placed on the rails of the Rl, in order to allow the platforms to move relative to each other — as in lengths e, and height in accordance with the configuration of the log to be sawn.

4. When characterized in, p. 2, the machine uses a receiving device for ready-made bars (Figs. 19, 20, 18) consisting of a roller table with knives n, HI and, not at the end, prednaz (by starting to pick up the finished beam at the bottom and from the sides and its direction.
