Description
' @mungitura @anni @frn IMPROVEMENT IN LOOMS.
HENRY A. ELLIS, OF MYSTIC RIVER, CONNECTICUT, ASSIGNOR T() HIM- SELF AND PEQUOT MACHINE COMPANY, 0F SAME PLACE.
Letters .Patent No. 59,987, dated November 2l, 1866.
SPECIFIGA.'I'Iorrsn` TO ALL WHOM IT MAY CONCERN:
Be it known that I, HENRY A. ELLIS, of Mystic River, New London county, Stateof Connecticut, have invented certain new and useful Improvements in Looms and I do hereby declare that the following is al full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this speeication, `in whichr Figure 1 is a front elevation of the frame of a loom, having my improvements applied toit.
Figure 2 is an elevation of one side of the loom.
Figure 3 is a transverse section takenV through the loom at the point indicated by line a; a2, in iig. 2.
Figure 4 is an enlarged view of the harness levers and its adjusting hooks.
Figures 5 and 6 show the construction of the shell camsfr operating the levers.`
Similar letters of reference indicate corresponding parts in the several figures. 1
My invention consists in a combination .of the slots in the levers with slots in the out'er rims of the cams,
. in such manner that either one of the levers maybe detached from the cam withoutdeta-ching such lever'from its bearing, and also in such manner that any one of the levers can be detached both from the cam and from its bearing without disturbing the other levers. My invention consists further in the construction .of each of the levers with a hook-slot at the pointwhere `it vibrates, with a cam-traversing pin projecting directly from its face, and with screw hooks for holding and adjusting the heddles.
To enable others skilled in the art to understand my invention, I will describe its `construction and operation.-
In the accompanying drawings, A represents the frame of the loom, which may be constructed in the usual i manner; B B are two heddles, by which the threads of the warp are alternately. raised or depressed; and a i1. are the cords by which these heddles are attached to theends of vibrating levers C C, which cords pass around pulleys b b', as shown in` figs. l and 3. I have represented but two heddles4 in `the drawings, but in practices number of them will be used, according-to the figure which it is desired to weave. TheleversC C `are arranged to vibrate in vertical planes, and are hung to a rod c, which has its end 4bearings in bracketsprojectingfromthe end of the loom frame. These levers are constructed with slots ol, which incline downward and, form hooked receptacles for the rod c, for the purpose of allowing of the attachment and detachment of any one of the levers from said rod, without removing this rod from its bearings or disturbingother levers. The slots al are made slightly oblique to the length of the levers lfor the purpose of prevcntingthe latter from slipping oil"A their rod c. The levers C are constructed with hubs e, and also with segments el, for` the purpose of spacingthem upon their pivotal rod c, and preventing lateral looseness when they are vibrated. Below tlepivotal support of the vibrating levers C is a secondary frame A', which is secured to one end4 of the main frame A, and adapted,` to form a support for a horizontal shaft D, which receives a rotary motion from the main shaft of the loom. Upon this shaft D 4are keyed in a suitable manner the shell cams EE, for vibrating the leversC C, the lower armsof which work between these cams, as shown in the drawings. The cams are all constructed with a groove' g, cfan' elliptical form in their faces, and are adjusted upon their shaft D, so that the longest diameter of one cam slot shall be at right angles to the corresponding diameter of the cam slot of the next cam,- for the purpose of giving an equal, length of vibration to both levers C C. The connection of the levers with the cams is made by means of pins h, projecting from the sides of thev levers and entering the yelliptical slots. At suitable rpoints on. the
faces of the cams E E, and at the circumferenccithereof, grooves or notches, z', are made of 3suiicient width to admit the pins h to pass through them in entering or' leaving the slots g.' The object of making thcsegroo'vcs, a', in the cams, is to allow of the insertion and removal of` the pins h' without detaching the cams `E from their shaft, and without detaching'the levers C from their rod c. This notch,'z', in each cam, obviatesthe necessity of loosening the several cams on shaft D when it is desired to remove one of the leversC, or to throwfit outf action; also to admit of the removall of the camplates,-wthout detaching the levers'from-their rod c', The
harness cords a a are attached toA hooks which are formed on short screw-rods rrfthat pass loosely througheyes which are formed on the extremities of the levers C, and receive upon their ends nuts es by which the harness can be `adjusted and levelled without detaching the cords from said hooks.
Having thus Adescribed my invention, what I claim as new, and desire to secure by Letters Patent,`is
I do not claim a lever with a branch arm `which carries aV traversing pin nor dol I claim a lever per se,
which has a. pin projecting directly from its face, andworking in a. cam; nor do I Gleim, broadly, providing for Elle separate removal of the jacks; nor do I claim, broadly, working a. pin in a. cam, which is partly left open; nor do I claim, broadly, a screw-adjusting device for afheddlevor heddles; but what I do claim as my invention, and desire to secure by Letters Patent, is-
1. The construction'of the lever O, with a. slot d, pin 7L, `and screw hooks r 1', substantially as and for the purposes set forth.
2. The combination of the slots d in levers C with the slots i in the outer rims of the cams E, substantially as described. I
