STOPPING- MECHANISM FOR LOOMS.
Specification of Letters Patent.
Patented J uneS, 1920.
Application led January 24, 1919. Serial No. 272,832.
vide a simple and effective mechanism for.
stopping the loom under all conditions through the action of protector mechanism such as that the action of which is initiated through the failure of the shuttle to become properly boxed at either end of the pick.
The invention is especially applicable to wide looms wherein it is necessary to provide mechanism at both sides of the loom to insure the operation of the stopping mechanism. The general principle of such mechanism is illustrated in the patent to Stimpson No. 726,589 granted April 28, 1903, wherein a frog is provided at each side of the loom and in which either frog when moved operates through certain connections to throw off the power. In the present invention the power controller and brake mechanism is preferably of the type disclosed in the patent to Ambler No. 867 ,9311 granted October 8, 1907. In this construction the lever or handle by which the power controller is' actuated, and also the lever or handle by which the brake mechanism is operated swings forwardly to running position and rearwardly to throw 0E the power and set the brake mechanism. In this construction also the power controller is brought to running position through the agency of a starter rod rotatably journaled at thefront of the breast beam, extending across the loom, and provided with a plurality of handles so that the starter rod may be operated at a number of different points to bring the power controller to running position.
One feature of the present invention resides in transmitting the movement of the frog at the side of the loom opposite the power controller to the power controller through the starter rod so as to operate the power controller to throw off the power without interfering with the use of the starter rod as a means for bringing the power controller to running position.
. Another feature of the invention resides 1n an improved and effective means .for transmitting the movement of the frog at the side of the loom opposite the power controller to the power controller to operate the same to throw oft1 the power. Y Y
The 'invention is of value irrespective of the particular source of power employed for operating the loom but is particularly useful when the loom is run by an individual electric motor clutched to the shaft of the loom. If upon the actuation of the protector mechanism the power is not thrown off the lay may be locked while the motor will continue to run thus slipping the clutch and in all probability causing the motor to burn out. Such a result is prevented in a simple n vand effective manner by this invention.
These and other Vobjects and features vof the invention will 'appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.
In the drawings Figure 1 is a view in side elevation of so much of a loom of the well known Northrop type provided with an individual electric motor and with a preferred form of the present invention as is necessary to a disclosure of the invention;
Fig. 2 is a view in end elevation and partially in vertical cross section of a portion of the said loom looking toward the side of the loom at which the filling carrier hopper is located or at that side opposite the side at which the power controller is located;
Fig. 3 is a detail of the construction shown in Fig. 2 with the parts illustrated in position for knocking off or operating the power controller;
Fig. 4 is a detail in front elevation of the construction shown in F ig. 3.
Inasmuch as the protector mechanism and the power controlling mechanism and brake mechanism and the general construction of tures is fully illustrated and described in the before-mentioned patent to Ambler it is unnecessary here to describe the same in detail.
In the construction illustrated the main Y driving shaft 5 of the loom carries a gear 6 driven from a pinion 7 on the shaft 8 of an individual electric motor 9. A clutch between the gear 6 and its shaft 5' is controlled through connections such as described in the before-mentioned patent to Amblerfrom a power controller shown as a lever 10. ful- 10 is swung rearwardly the clutch is disconnected to throw off the power and the power controller comes against the stop 14.
.Suitable brake Vmechanism is providedV such for `example as shown in the beforementioned patent to Ambler including an annular member 15 Vmounted upon the crank shaft 16 of the loom and encircled'by a friction brake band 17 having connection with a brake lever 18 also fulcrumed at 11. When the brake lever 18 is in forward position, as shownV in Fig. 1, the brake band is re- Y leased. The brake lever 18 when swung to rearward position acts to swing rearwardly the powerV controller 10 through the agency ofthe screw 19contacting with the depending arm 20 and when thus swung to rearward position acts through the connections to bring the brake bandinto frictional engagement with the annular member 15 and thus set the brake mechanism.
. A starter rod 2 1 is rotatably j ournaled in bearings at the front of the breast beam and extends across the loom. At suitable intervals of its length it is provided with handles 22 having a lost motion connection therewith. At the power controller side of the loom an arm 23 projects from the starter rod and is `adapted at its lower end'to engage behind a stud 21 projecting laterally from the power controller `10.y Hence the operator standing at any position in front of the loom by seizing and elevating one of the handles 22 is enabled to swing the power controller 'forwardly and bring it to running position.
The protector mechanism illustrated is of that type whichr is actuated by the failure of the running shuttle to become properly boxed at either end of the pick. Such a protectorl mechanism includes a frog 25 mounted to slide forwardly and rearwardly on the loom frame at the power controller side and another frog 26 mounted to slide in asimilar manner on the opposite side frame 27 of the loom. These frogs are caught and moved forwardly by dagger-s, one of which 28 is shown projecting from Va protector shaft 29 mountedl on the lay.
Upon the beat up of the lay if the shuttle fails properly to enter either box at the end of its"picl{`one or the other of the binder fingers 30 enters the shuttle box allowing the daggers to drop into engagement with the frogs and thus as the beat up of the lay concludes to move the frogs forwardly. It is desirable that such a movement of'each of the frogs lshall effect the operation of the power controller so that if for any reason one of thev frogs is not properly actuated the one which is actuated,whichever one it may be, will effect the throwing off of the power.
The frog 2 5 at the power controller side of the loom is provided with a depending bunter 31 so that when it is vmovedv forwardly it contacts directly with the depend ing portion20 of the brake lever 18 and acts therethrough to' swing the brake lever and simultaneously the power controller 10 rearwardly to throw olf the power and set `the brake mechanism. y
The present invention is concerned more particularly, however, with ,securing jthe operation of the power controller, and also the brake mechanism from the frog 26 at the` lopposite side of the loom. For this purpose the starter rod 21 is preferably utilized and in such a way as not to Vinterfere with its operationas a ystarter rod. In the construction illustrated a ,lever of the,` bell crank type 32 is fulcrumed at. 38 on the loom side adjacent the frog 26 Vwith. one arm extending toward .the frog while the other arm extends upwardly adjacent the starter rod. Another arm 3,41` is secured to the starter rod and projects above Y'the end of the bell crank lever 3.2 and into the path of the same. At the opposite yside *of the loom an operative'conneotion is made between the starter rodv andthe power oontroller and as a simple vmeans for securing this connection the arm 2.3 already described may be provided with a lug 35 projecting laterally therefrom so as to come opposite the front edge of the .power controller or lever 10. p
If now the frog 26Y be moved forwardly it will contact withthe lever 32 and "swing this lever about its pivot, the lever in turn striking the arm 84 will rotate or rock the starter rod 21, in the direction opposite to that which takes place when the starter rod is employed to' start the loom, and consequently Vwill swing the arm 23 rearwardly Y the brake mechanism. It will also be seen that this is effected preferably through the usual starter rod without in any way intertering with the normal function of the starter rod.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:
1. A loom comprising protector mechanism including a frog at one side of the loom, a power controller at the opposite side of the loom, a starter rod extending across the loom and operative when rotated in one direction to move ,the power controller to running position, and means governed by or through movement of said frog acting to rotate said starter rod in the opposite direction and therethrough to operate the power controller to throw off the power.
