SAURER, or nRBoN, SWITZERLAND, A CORPQRA'IION or sWITzERLAnD LO OM Application filed May 12, 1931, Serial No. 536,761, and in Germany May 27, 1930.

The driving elements of power looms, particularly the driving means for the lathe, theshuttle, and the heddles as well as the clothbeam regulator usually have their bearings in the standards of the machine frame, in suchwise, that at each side of the loom only a single frame or standard serves for the bearing of the shafts of the driving gears of the loom. This single, one sided bearing of the driving shafts at each side of the loom frame, has the disadvantage that the bearing pressures aresustained'in a single bearing in a single standard only and the driving gears in consequence have an insufficientsupport. As a result, the driving mechanism is subjected to disrupting strains, and in a short time sure control of the driving mechanism will be lost. The bearings will be worn and there will occur an appreciable play between the shafts on the one hand and their bearings on the other, seriously affecting'the accurate operation of the 100m.

According to the present invention these.

disadvantages are avoided by forming the supporting frames or standards with multiple, spaced walls and the shafts of the driving gears have multiple bearings in the walls of the standards. In this way is assured a stable and vibrationless support. of the driving mechanism, and furthermore the bearing pressures are transmitted uniformly to the standards or frames at each side of the machine.

In prior arrangements there is the further disadvantage that the driving means, having bearings in open standards of the machine frame, are exposed to dust, lint and the like which will penetrate the bearings and may cause interruptions in operation. There is the further disadvantage of unprotected driving means that the material produced by the loom may be spattered by machine oil, etc. Moreover, unprotected driving means are naturally an ever present danger to the persons operating the loom. All of these disadvantages are also avoided in the present invention by making the stand ards boxlike or with multiple, spaced walls,

Figures .5 and 6 are detail views in sec-- tional elevation illustrating modifications.v

- The elements of the loom mechanism are driven from a loom shaft 2 within a tubular frame member 1 which isvsecured to the box like, supporting standards 6 and/Z and reinforces the loom frame. .An extension 3 of the shaft 2n1ay be actuated through a coupling 4 by arbelt, and pulley, as at 5.;

The extensions ofthe shaft 2 are mounted in bearings 8, 8a and 9, 9a in the bI XVlike,

supporting standards 6 and 7 Upon-each of the extensions of the shaft 2 are fixedly mounted within the boxlike supporting standards 6 and 7 with spaced-walls,qrespectively two gear wheels 10, 10m and 11, 110, which mesh with corresponding wheels 12, 1200 and 13, 13w also mounted within the boxlike standards v(Sand 7. Each of the wheels 12, 12a and 13, 13a; is rotatably mountedon a separate aligned bearing stud fixed to the correspondingside-wall of the standards 6 and. 7. respectively, so that there is assureda quiet running of these wheels. The two wheels 12 and 12a as Well as the wheels 13 and 13a are connected with each other through an accentric pin 14. and 15, with each ofwhich is engaged a connecting rod 1,6,.17 respectively. The free ends of these rods are flexibly connected with the oscillating lathe arms 18 mounted at the two sides of the loom within the boxlike standards 6 and '7 respectively. Through the crank gears formed by the wheels 12, 12a, 13, 13aand the connecting rods. 16 and 17-,

there may be imparted to the lathe arms 18 as well as to the lathe 19 supported thereby the movement necessary to permit the passage of the shuttle. The axes 20 (Figure 1) of the lathe arms 18 are also mounted in the standards 6, 7, respectively, with two bearings, that is,-in'both side walls of the stand ards. I

\Vith the gears 12a and 13 mesh respectively other gears 21 and 22, the axes 23 of which, as may be seen at the'left hand in Figure 2, are also mounted with two bearings in the two standards 6 and 7 respectively. Thegears 21, 22 serve to actuate the picker sticks 24 for the shuttle 25. For this purpose there is fixed to each of the two gears 21, 22, respectively, a cam 26 (Figure 3) which through the lever 27 actuates the shoe 28(Figure 1) of-the picker" stick 2 1.

In the standards 6 and 7 there is also rotatably mounted the axis 29 of the'clothbeam 30 in two bearings 31 and 32, respectively. In addition there is mounted in two hearings in the standard 6, as may be seen in Figures 2a and 3, thecross-shaft 33 of the clothbeam regulator.

The standard 7 further serves to support the heddle operating elements. sist, as shown in Figure 4, of two worm gears 35 and 36, the 'first of which is fixedto the end'of' the shaft 2 extending into the standard 7, while the axis 37 of the worm gear 36 'is rotatably mounted in two bearings 39 and 40 provided in a portion 38 of the standard 7. Upon theaXis 37 are jfixed severalcam disks 42, corresponding-to the number of theheddles 41 (Figure 3),- each of the disks being provided with" a cam groove 43. (Figure In the cam groove of each disk'42 is engaged the'roller 44 of a double lever 45 mounted in the loom frame, whichlever, during operation of the loom, transmits the motion determined by the cam groove 43 through intermediate connections 46 to the proper heddl'e. :In this manner there is imparted-to the heddles'4=1 the movement necessary for the formation of-the shed. 1 Q

In Figures 5 and 6 are shown two modifications of the standards 6 and 7 In the construction shown 1nFigure 5 the standard is formed of a frame-like center part, which at both sides is closed by walls 48 and 49, respectively, provided with bearing bosses 50, 51 necessary forsupport-ingthe several shafts of the driving elements. Y 3 j The standard'of Figure 6 isformed of two parts 52 and 53, whichjare joined by means of the flanges 54 and are provided with bearing bosses 50 and 51. r

Because the standards 6 and 7, receiving the driving mechanism, that is, their arms and shafts, are made'with double, spaced walls a stable bearing for the driving inech These con- 7 "driving parts of theloom'is avoided.

"The fact thatthe' shaft2 is received in ahollow frame piece 1 connecting the two standards has the advantage that the frame of the loom is reinforced. and that threads drawn off over the on theshaft; 5
