LOOM-LAY MOUNTING.

Application led June 3, 1926, Serial No. 113,368, and in Germany .Tune 17, 1925.

This invention has reference to im rovements in the operation of looms an it is particularly intended to devise means of utilizing substantially the entire amount of the kinetic and oscillating energy imparted to the lay or vhatten of a loom, so as to arriveat a great economy of power as compared with the operation of looms in accordance with previous constructions. In view thereof the layor batten in accordance with this invention is not merely oscillated by crank operation or the like, but the lay or hatten is spring-actuatingly arranged and in such a manner that the rocking movement in one direction is automatically succeeded by a spring-actuatingly occurring rocking movement in the opposite direction, such movement taking place in phase with the natural oscillating frequency of the device, so that substantially only enough power is required to maint-ain the oscillating movements and suficient for the beating up of the filling threads by the lay or hatten.

In rthe constructions of lays, as at presentemployed the kinetic' energy produced by the mass of the lay or hatten in its rocking movement had to be destroyed twice in the driving operation, and on the other hand the entire mass of the lay had to be again twice accelerated, and in view thereof a rather very considerable amount` of power was necessary which is greatly reduced in the construction according to this invention. By means of this new construction the amount of power required may be reduced to about 40 per cent with the additional ad vantage of a very much smoother movement of the loom.

The invention will be more `fully described with reference to the accompanying drawing showing by way of exemplification one of the various possible forms of embodiment of the principles of my invention.

Fig. 1 shows a loom with a batten according to this invention in partsectional view and Figure 2 is an elevation of the batten or lay with the frame of the loom in transverse section.

In the frame l of the loom the lay swords l or supports 2 of the lay or hatten are secured for oscillating movement in any suitable manner, thus for instance, by means of angular clamps or the like. The lay swords preferably comprise a plurality of stepped leaf springs of dierent lengths in accordance with the desired number of revolutions of the loom and with the mass of the lay.

The lay swords are connected in the usual manner by means of the lay beam 3 and the voperation may be effected as ordinarily by crank drive, it produces a higher degree of uniformity and thereby results in a smoother movement of the loom itself.

The spring acting movement of the lay may also be produced by other spring acting elements, such as for instance tensional springs or coiled springs mounted on the shaft of the lay, and other changes and modifications in the selection and arrangement of parts may be introduced without deviating from the spirit and scope of the invention, as particularly set forth in the appended claims.

I claim:

l. In a loom, a lay, a plurality of com bined superimposed leaf springs fixed at one end for oscillating motion and connected to the lay and constituting lay swords, and driving means operatively connected to the lay.

2. In a loom, a lay, a resilient oscillatory support for the lay of leaf spring construction, and driving means for oscillating said support.

3. In a loom, a lay, a spring support for the lay fixed at its lower end for resilient oscillatory movements responsive to the oscillatory movements of the lay, and a positive driving means for the lay operating to tension the spring support on the forward driving motion of the lay.

4. In a loom, a lay, a spring sword normally oscillatable when tensioned through a range extending to equal degrees in opposite directions beyond a neutral plane, and means for moving such sword to and fro.

5. In a loom, a lay, a spring support for the lay, connected at its upper end to the lay and at its lower end to the loom freine,4

said support being normally operated when tensioned for vibration to vibrate to equal degrees in opposite directions beyond a neu- 5 tral'position, and drivingmeans for Vibrat- V ing said support.

6. In a loom, a frame, a,` lay, leaf spring v v supports for the lay secured at their upper ends to the ends of the lay and at their lower ends to the sides of the loom frame, 10 and driving means for oscillating the lay Y and supports;

In testimony whereof-I aflxr my signature. PAUL ESTERS.
