APPLIANCE FOR BEATING UP THE WEFT IN LOOMS.

SPECIFICATION forming part of Letters Patent No. 696,263, dated March 25, 1902.

Application filed July 1 T ctlZ whom it may concern:

Be it known that we, HEINRICH PANIT- SCHEK and CARL HERoLD, citizens of the Empire of Austria-Hungary, and residents of 4% Leile, Brtinn, Empire of Austria-I'Iungary, have invented a new Appliance for Beating Up the Weft in Looms; and we do hereby declare the following to be a full, clear, and exact description of the same.

This invention consists of an appliance for form of reed-shaft; Fig. 5, a cross-section of the shuttle-race; Fig. 6, a part front elevation of the same; Figs. 7 to 10, a series of diagrams showing the various operative positions of the reedshaft and reed.

The slay or lathe hot the loom is fixed and the reed serves merely to separate the warpthreads. In front of the slay 1 the reedshaft 2 is placed, which, except at its bearings, is of rectangular section. On the shaft 2 reed-blades a are placed and are kept at the desired distance apart byinterine'diate disks 1). The individual reed-blades are set to make radially angles of ninety degrees with each other. The order in which those of a series follow each other (in the drawings four compose a series) isarbitrary'; but the arrangement of each series must always be in one and the same order. reed-shaft 2 is put together so as to make four combs, inwhich the dents of each single comb 7c are outof linein a direction parallel to the axis with the teeth of another comb. The separate reed-plates a are placed out of line with each other, as explained, so as to form an arrangement of dents which are displaced with regard to each other, and thus the formation of stripes along the cloth is avoided. The shaft 2may, if desired, have a In this way the- Serial No. 23,671. (No model.)

section with'three or more than four angles in order to make three or more combs 70, or, if desired, two combs only may be arranged. on the rectangular shaft.

The method of action of the shaft is the same whether it has more or fewer combs 7c and an alteration only in the velocity and in the cam is needful.

The shaft 2 turns in a bearing at one end in the arms 3 of a bent lever 5, keyed on a shaft 4, while at the other end it has a bearing in a similar crank-arm keyed on the same shaft 4. ,f

In orderto impart the requisite movement for beating up to the reed-shaft 2, a'chainwheel 7 is placed to run loose on the shaft 4, driven from a chain-wheel 9, keyed on the main shaft b, giving a velocity in the ratio of one to two. There is fixed to the chainwheel 7 or made in one piece with it'a toothed wheel 10, gearing with a second toothed wheel 11, keyed onthe reed-shaft 2. These toothed wheels are of equaldiameters and have same number ofteeth.

The contrivance described produces, as will be afterward explained, an intermittent motion of the reed-shaft 2, and its risingand falling is effected by causingthe' bent lever to be actuated from a cam 13, fixed on the main shaft 8. r

In the groove ll of the cam 13 there is a roller 15, capable .of revolving, attached to the free end of a lever 16, of which the fulcrum is at 16 in the frame of the loom. Opposite to the roller 15 the lever 16 has an eye 17, by which it isjointed'toa connectingrod1S, the other end of which is provided with an attaching-bolt passing through a slot 19 to the arm 12 of the bent lever 5.

g The action of the arrangement thus described is as follows: Let it be snpposed,first, that the reed-shaft is in the beating-up position, Figs. 1 and 7, and after the shed has been changed that the weft 20 previously laid in the shed has been beaten up to the cloth. At the same instant the weft begins to be sent through the crossed and open shed, Fig. 7 ,and then the reed-shaft zdrops. This is effected by the connecting-rod 18 having been pushed during this interval toward the left, which has caused the bell-crank lever 5 to turn in the direction of the arrow, Fig. 7. By this turning movement of the bell-crank lever 5 the turning of the shaft 2 ceases momentarily, since the angular velocity of the arm 3 is the same as the velocity of the continuously-driven toothed wheel 10. As the reed-shaft 2 drops, the reeds which were just before in the beating up position move slightly backward to the right, since at the instant of their moving down the mechanism last described forms a rigid system, which is turning round the shaft 4. If a slight backward movement of the reeds in question did not take place, they might in the downward movement of the reed-shaft 2 drag along with them the finished cloth. During the turning of the bent lever 5 the shuttle has traveled across, has drawn in the weft, and is in the other box. The shed now begins to close, Fig. 9, the reed-shaft begins to rise and to turn rapidly, since, on the one hand, the connect-- ing-rod 18 is pulled to the right by the cam 13, and, on the other hand, the one toothed wheel 10 drives the other toothed wheel 11 positively. The reed-shaft is lifted in this way to the position Fig. 10 to grasp the weft already laid in and beat it up, when the shed has been again crossed against the finished cloth, Fig. 7, since the construction of the cam is such that the turning of the reedshaft through a little more than ninety degrees is produced. The excess of the turning beyond ninety degrees corresponds exactly with the backward movement from the position of Fig. 7 to that of Fig. 9.

In order toinsure the certainty of the reeds catching the weft, the latter must be laid as close as possible up to the apex of the shed, and this is effected by applying an attachment or projection 21 to the shuttle, through an eye in which the weft is passed. In consequence'of the projection 21 the front side 0 of the shuttle-box mu'st havein ita long slit in order to allow the shuttle to enter it, Figs. 5 and 6, and a stirrup-piece 22, fitted to the front side 0 of the shuttle-box,serves the purpose of stiffening it.

A modified form of reed-shaft 2 (shown at Fig. 4) is made of a tube f, with grooves (1 along its length in which the reed-blades a are placed, making angles of ninety degrees with each other, the holes through which are formed with projections g corresponding with the grooves d.

Having thus described our invention, what we claim is 1. In a loom, the combination with a sta tionary lathe, of a shaft mounted in front of the same, a series of combs on said shaft, and means for rotating the said combs to beat home the weft and-for swinging the said combshaft up and down to withdraw the said combs at intervals from the fabric, substantially as described.

2. In a loom, the combination with a stationary lathe, of a shaft provided with combs and arranged in front of said lathe, crankarms in which said shaft is journaled, means for simultaneously actuating said arms to raise and lower the shaft, and means for retating the combs to beat the weft.

3. In a 100m, the combination with a stationary lathe, of a shaft provided with combs and arranged in front of said lathe, a shaft carrying crank-arms in which said comb-shaft is journaled, a main driving-shaft, a cam on said driving-shaft, and connections between said cam and another crank-arm on the shaft.

4. A device for beating up the weft in looms, consisting of the combination of an intermittently-rotated shaft 2 having thereon a series of axially and radially displaced combs, and meansforswinging the said shaft up and down in order to beat up the weft and to be withdrawn from the Work while the next weft is being passed through the shed.

5. In a' loom, the combination with a stationary lathe, of a rotatable shaft carrying combs, crank-arm in which said shaftis journaled, gear-wheels for rotating the shaft, means for actuating said wheels, and means for rocking the crank-arm.

G. In a loom, the combination with a stationary lathe, of a shaft 4, crank-arm on said shaft, a reed-shaft 2 journaled in said arms, intermeshing gear wheels 011 said shafts, means for driving the gears, and means for rocking the shaft 4.

7. In a loom, the combination with a stationary lathe, of a shaft 4, crank-arm on said shaft, a reed-shaft 2 j urnaled in said arm, a loose gear-wheel on the shaft 4, an intermeshing gear-wheel of the same size secured on the shaft 2, means for rotating the loose gear-wheel, and means for rocking the shaft 4.

In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
