Saw frame Patented in the German Empire on November 9, 1929

Hs is known, saw frame for the purpose of better economic utilization with mechanical to equip movable saw blades. For this purpose the hinges of the saws are in special slides are attached, which by turning right and left-hand spindles can be set in motion in such a way that the saws or saw bundles together or move apart. It is also with saw gates

ίο common to interchangeable or between saws to arrange adjustable shims that determine the distance between the saws and you Prevent it from running in the wood. The new saw frame differs from the familiar one in that with the load carriage in which the saws are clamped with their hinges, the spacers are also inevitably moved. It is particularly pointed out that in a saw frame constructed in this way, the aforementioned device according to the invention does not serve to tension the saws lengthways, but is used to move the saw blades precisely adjust and guide. This device is designed so that also the saw bundle can be adjusted by hand by means of a bushing on the spindle to achieve precise plumbing and angling.

Furthermore, the individual saw blades

of the bundle by suitable device, such as

z. B. Nuremberg scissors, etc., are mechanically adjusted against each other in order to achieve _{different cut 7 strength between the saws of the bundle.}

The invention is shown schematically in the drawing, and it shows

Fig. Ι the gate frame in view,

Fig. 2 a part of the guide device with the position of the saw bundle for the square timber cut,

Fig. 3 a part of the guide device with the position of the saw bundle for the square timber cut, in addition, the individual saws of the bundle can still be adjusted.

The saws α are firmly clamped in the load carriage c with the interposition of hinges b. The latter are by left- and right-hand spindles d coupled to each other such that upon rotation thereof \ ⁷ erschieben Sägebündel the inside or the outside is carried out, to achieve the purposes, other cutting thicknesses for the timber. The adjustment is carried out by an actuating device e arranged on the housing of the gate, which is connected to the spindles d , for example by a worm gear mechanism f and bevel gears g .

The saws α are again guided at their ends in holding members which, for. B. can consist of sockets h . These sockets h sit on the likewise right-hand and left-hand spindle i, which is driven by a gear, chain ο. Like. k is connected to the drive d of the load carriage c . If the load carriage c is moved by means of the spindle d, a 6g rotation of the spindle i takes place at the same time and inevitably, with the result that

the bushings h including the saws α can also be moved.

In order to be able to make a fine adjustment of the saw bundle for yourself, the bush h can be moved on the spindle i . In addition, the individual saw blades of the bundle can be shifted against each other by means of suitable devices, for example Nuremberg scissors /, which makes it possible to achieve other cutting thicknesses of the boards. Such an adjustment can optionally be carried out by the spindle i , the bushing h being provided with a shoulder m which is brought into connection with the coupling piece η wedged onto the spindle /.

It should also be noted that, as is customary when using register spindles, two spindles i arranged one behind the other are used, "between which the saws a lie. If the individual saws are not to be adjusted according to Fig. 3, the distances between the sawing of the bundle in a known manner by means of spacers 0, which determine the cutting thickness.

Claims (5)

Patent claims: i. Saw frame in which the saws are clamped in transversely displaceable load slides are, characterized in that the saws («) are also guided in special holding members, for example bushes (7t) and are determined against each other and the latter together and inevitably with the Load carriage (c) can be moved inwards or outwards perpendicular to the plane of the saw blade. 2. Embodiment of the gate frame according to claim 1, characterized in that the holding members (h) are moved by spindles (i) which are connected to the spindle drive of the load carriage (c) by gears, chains or the like (k) and with this inevitably can be rotated. 3. Embodiment of the gate frame according to claims 1 and 2, characterized in that the holding elements (h ) arranged on the spindles [i) , through which the saw blades («) are guided, can be moved separately in order to precisely adjust the saw bundles (") to reach. 4. embodiment of the gate frame according to claims 1 to 3, characterized in that the individual saws (a) on the spindle sleeve (h) by means of suitable devices, for example Nuremberg scissors (/), can be moved against each other for the purpose of setting different cutting thicknesses. 5. Embodiment of the gate frame according to claims 1 to 4, characterized in that the spindle bushing (A) is provided with an extension (m) and the latter can be brought into connection with a coupling part (s) arranged on the spindle in order to adjust the saw blades themselves by turning the "~ spindle (i) .
