JOHN JOHNSON, OF CHESTER, PENNSYLVANIA.

HARNESS-HOOK FOR Looms.

SPECIFICATION forming part of Letters Patent No. 498,474, dated May 30, 1893.

Application filed August 27, 1891- Serial No. 403,889. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN JOHNSON, a citizen of the United States, residing at Chester, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Harness-Hooks for Looms; and I do hereby declare the following to be a full, clear, and exact description of the inventwo, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to harness for looms and It consists of a double hook adapted to engage two frames forming the harness, thus Insuring an even motion to both of them and the heddles contained therein, whereby the shedding of the warps is more regular.

Heretofore, it has been the practice to have screw eye bolts secured in each heddle frame, and these screw eye bolts being very long, consequently require a considerable time to screw them into the frame, which being very thin is apt to split, as has been the experience ofany one who has performed this work. After these screw bolts are secured to the harness frame, two of such frames are placed side by side and a strap is secured to one of the frames and run through the eye of the opposite eye bolt in the adjacent frame so that they will reciprocate together. Now it has been found in actual experience that the two frames thus joined or hung do not work evenly as they are not always parallel nor in the same plane. Consequently the shedding of the warps is not even. Frequently the eye: bolts lock with each other and damage to the frames and material results. Whereas,by the use of my double hook all of these objections are obviated, as the two frames composing the harness,must of necessity move together and inthe same plane thus making the sheds even. Further the frames are not split by the use of my double hook, and they can be applied much quicker.

In the drawings: Figure 1 is a front view of a harness frame showing my invention in use. Fig.2 is an end view of the same. Fig. 3 is a side view of my improved hook detached. Fig. 4 is a front view of the same.

A represents the harness composed of the two frames A and A each of which have the top and bottom bars a and a and the side bars I) in which the end of the heddle bars 0 are secured. B are the heddles which are hung on said heddle bars.

E is my improved double hook the stem of which has a triangular eye 6 on its upper end and a plate with two upturned ends or hooks e e secured to the lower end of the stem. It will be observed that the eye eand the hooks e are at right angles to each other. Secured to the eye of this hook is the strap F which is, in the usual manner, connected to the loom proper.

To attach these hooks they are turned endwise and slipped between two frames until they pass the end bars b when they are turned into their proper position as seen in Fig. 1 and can be readily adjusted to any position desired. Thus it will be seen that all liability of cracking the frame by screwing the eye bolts in the same is obviated, that frames composing the harness will move together and in the same plane and that the hooks as shown in the drawings can be readily attached to or detached from the frames as may be desired; further that the shedding in the warps is always even. 7

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

The combination with the heddle frames consisting of the horizontal and vertical pieces and heddles carried thereby, of a hook consisting of a straight stem the upper end of which is bent to form a triangular eye, the plate secured to the lower end of said stem at right angles to the eye, the ends of said plate being turned up on opposite sides of said stem, and each embracing a horizontal member of the two frames with the stem extending between said frames, substantially as described. I

In testimony whereof I hereby affix my signature in presence of two witnesses.

' JOHN JOHNSON.
