WILLIAM WATTIE, OF WORCESTER, MASSACHUSETTS, ASSIGNOR TO CROMPTON & KNOWLES LOOM WORKS, A CORPORATION OF MASSACHUSETTS.

LOOM.

Specification of Letters Patent.

Patented Nov. 26, 1907.

Original application filed February 3. 1905. Serial No. 243,925- Divided and this application filed April 19. 1907. Serial No. 369.069.

To all who'm 'it may concern:

Be it known that I, WILLIAM WATTIE, a citizen of the United States, residing at Worcester,-in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Looms, of which the following is a specification.

My invention relates to looms, and more articularly to the filling beating up motion or a loom, which motion is shown and described but not claimed in my application for a patent, Serial No. 243,925, of which this application is a division.

The object of my invention is to provide an improved filling beating up motion for looms, adapted to be used on looms for weaving different classes of fabric.

11 my improvements in fillin beatin up motion, I rovide a series of b ades, which are prefera 1y made separate, and provided hubs, which are preferably fast on a rock shaft. The warp threads ass between the blades, which act as a ree to separate and guide the warps, and also act to beat up the lling, after it is inserted in the shed. The blades are made so that they always extend through the war threads, and above the War threads in t e upper plane of the shed, w en said blades are in their extreme backward position.

My invention consists in certain novel features of construction of my improvements as will be hereinafter fully described.

I have only shown in the drawing a detached portion of a loom, with my impro vements in fillin beating up motion combined therewith, su cient to enable those skilled in the art to understandthe construction and operation thereof.

Referring to the drawi :Fi ure 1 is a sectional e evation of my ling beating up motion, taken at a point indicated by line 1, 1, Fig. 2, lookin in the direction of arrow (1, same figure. an Fig. 2 is a section, on line 2, 2, Fig. 1,,looking in the direction of arrow 1), same figure; the harnesses are not shown in this figure.

In the accompanying drawing, 1 is a loom side or end frame, 2 are the harnesses, in this instance four in number. 3 are the warps, which are threaded through the heddles in the harnesses, and ass over the roll 4 at the front of the breast earn 5.

I willnow describe my improvements in beating up motion.

A rock shaft 6 extends through the loom, in front of the harnesses, and is mounted in this instance at each end in suitable bearings 7, on stands 8 secured to the inner side of the loom frame. The shaft 6 has fast on one end the hub 9 ofan arm 9; the end of the arm 9 carries a pin 10 with which is pivotally connected the forked end 11' of a cam lever or arm 1 1; the other end 11 of the cam lever or arm 11 is also made forked shaped or slotted, to receive a driven shaft 12. The shaft 12 has fast thereon a cam 13, having a cam groove 13 in one face thereof, into which extends a roll 14.0n a stud 15, carried on the cam lever or arm 11. Through the rotation of the shaft 12 and the cam 13, and the engagement of the roll 14 with the cam groove 13 in said cam, and the movement of the cam lever 11, a rocking movement is communicated to the shaft 6 at regular predetermined intervals. I

On the rock shaft 6 is mounted a series of blades 16 having hubs 16, which are referably made of the same thickness as the lades themselves. Separate collars or disks 17 are in .this instance mounted on the shaft 6, between the hubs 16 of the blades 16, to hold said blades at a proper distance a art to give a clearance for the war threa s 3 passing between said blades. T e hubs 16 of the blades 16 are preferably fast on the shaft 6, and may be attached to the shaft 6 in any suitable manner, in this instance they are attached by a key 6, see Fig. 1.

The blades 16 are preferably made of angular shape, as shown, with their upper ends extending toward the front of the 00m, and of such a length that they will extend through the war threads, and above the warp threads in t e upper plane of the shed, when the blades 6 are in their extreme backward position, as shown by full lines in Fig. 1. The series of blades 16 act as an ordinary reed, to separate and guide the warp threads, and to beat up the filling thread 18, which is inserted in the open shed in front of the blades 16, as shown in Fig. 1 The fillin beating up blades 16 are 0 suflicient-lengt to always extend above the war threads, and never pass below the upper p ane of the shed, formed by the warp threads, and will alwaysact to separate and guide the warp threads and prevent their becoming twisted or entan led.

The a vantages of my improvements will be readily appreciated by those skilled in the art. My improvements may be used on looms for weaving difierent classes of oods, particularly'heavy goods, as'cane, ducl i, etc.

It will be understood that the details of construction of my? improvements may be varied if desired.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent is 1. A filling beating up motion for a loom, comprising a shaft, and a series of filling beating up blades thereon, said blades hav ing a rocking motion, and in their lowest position extending above the warps in the up- .per plane of the shed, to separate the same and form uides therefor.

2. A filhng beating up motion for a loom, comprising a rock shaft, and a series of filling beatlng up blades fast thereon, said blades in their lowest position extendin above the warps in the upper lane of the s ed, to separate the same and orm guides therefor, and means for positively moving' said blades to beat up the filling.

WILLIAM WATTIE.
