THREAD-CUTTING TEMPLE FOR LOCI/ES.-
" Application filed October 9,1925; Serial No. 61,405."
To all whom it may concern:
Be it known that" I, ALrHoNsn LECOMTE, a citizen of the United States, and a resident of Fall River, countyof Bristol, State of Massachusetts, have invented an Improve ment in Thread-CuttingTemples for Looms, of which the followingdescription, in connection with the accompanying drawing, is a specification, like characters on the drawing representin g like parts.
This invention relates to a thread cuttin temple for looms and theprincipal object 6i the invention is'to provide a simple, eflicient and durable spring construction for effecting them'ovement of the usual movable cutter member to rearward or open projected position.
The nature and objects of the invention will appear more fully from the accompany' ing description and drawings and will be particularly pointedput inthe claims.
In the drawings:
Fig. 1 is a side elevation of the main portionof a thread cuttingftemple embodying a preferred form of the invention.
Fig. 2 is a view in front elevation and partially in cross section on the'line 2-2 of Fig. 1.
Fig. 3 is a View similar to a portion of Fig. 1 and illustrating a slight variation in the construction.
Fig. 4 is a view in horizontal cross section to show one form of the bracket construction.
Fig. '5 is a view in horizontal cross section on the line 5'5 of Fig.3to show the bracket construction.
Fig. 6 is a view in horizontal cross section on the line 66 of Fig. 2.
The thread cutting temple is such a widely known mechanism in connection-with looms that it is unnecesary here to illustrate and describe with any degree of detail the construction and operation of such a device,
' especially as the present invention relates to but one feature thereof.
The drawings illustrate, for the purpose of disclosing the present invention, a well known form of thread cutting temple such as is disclosed in the patent to Stimpson, No. 1,366,034, January 18, 1921, but the present invention is obviously not to be limited to any particular form of thread cutting temple. I
In the construction disclosed, the temple head 3 in which the shank terminates.
filling ends extending from the selvage of the fabric passing through the temple. Such athread cutting means usually, as in the form'illustrated, comprises a fixed blade mounted at the rear face of the temple head and a movable cutter member cooperating with the fixed blade. This movable cutter member is mounted to. rock vertically and slide longitudinally in a. slot in the temple head. In the form illustrated, the movable cutter member comprises a body portion 8 terminating at the rear in a hook-shaped end 9 having a cutting'edge 10 and terminating at the front in a downwardly depending heel 11. 'This movablecutter member must normally be moved or projected rearwardly and its hooked end 9 moved upwardly to bring it to open position so that the filling ends extending; from the selvage will come beneath the hooked end 9 or into its field of operation. Then as the lay beats up, the lay strikes the heel 11 and rocks the movable cutter member to swing the hooked end 9 downwardly and also moves the member forwardly, thus effecting the cutting action. ThIS operation is well-known and familiar to those skilled in the art and is disclosed in the Stimpson patent referred to.
Various means have been employed for rocking and sliding the movable cutter member into its open rearwardly projected position and. a great deal of difficulty has been experienced in practice in the construction and operation of many such devices. The present invention presents a simple, efficient, durable and practical means for securing this result.
In the construction illustrated in Figs. 1, 2 and 3, the heel 7 of the temple has rigidly secured thereto, as by means of the bolt 12, a bracket 13 which extends laterally in front of the heel 11 of the movable thread cutter member and is provided at its end opposite the heel 11 with a vertically extending slot 14. A stud 15, rigidly secured in the heel 11, projects forwardly therefrom and passes through the slot 14. A helical compression spring 16 is mounted upon and surrounds the stud 15 and extends between the bracket 13 and the heel 11, a'washcr 17 being preferably interposed at the bracket end.
The construction thus described is very cfiicient. The expanding thrust of the spring 16 takes place substantially in the direction of movement of the movable cutter member. The blow of the lay on the heel 11 is transmitted directly therethrough to the spring to effect its compression. There is little or nothing to wear out and the spring at any time may readily be replaced.
The bracket 13 may obviously be otherwise constructed and supported so long as it is rigid with the temple head and is positioned to guide the stud 15 and form an abutment for the spring 16.
In Fig. 4, the bracket 18 is shown as cast or formed integral with the heel portion 19 of the temple.
In the use of certain forms of looms such as those employing a high cloth roll take up, it is frequently necessary to have as little of the construction as possible extending forward of the temple heel and head so that the temple may be moved close up against the roll.
In Figs. 3 and 5, the construction is modified for this purpose. The heel 20 of the movable cutter member is here shown as thinned down somewhat at the top and provided with a comparatively short stud 21. The bracket 22 is shown as a flat plate secured by the bolt 23 to the heel 2a with an interposed washer 25. The helical spring 26 is correspondingly shortened. The proportions of the parts are such that when the heel 20 is carried back by the lay to bring its rear face in line with the rear face of the heel 2st of the temple, the spring 26 will be compressed about to its limit and will just fill the space between the heel 20 and the bracket 22. Thus the construction is reduced to the minimum.
It will be seen that the construction in one form or another may readily be applied to existing constructions as well as to new constructions.
Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is:
1,. A thread cutting temple for looms comprising a head having a depending heel, a movable cutter member having a depending heel and mounted to rock vertically and slide longitudinally in the head, a bracket extending laterally from the temple heel in front of the movable cutter member heel and having a vertical slot opposite the latter heel, a stud rigid with and projecting forwardly from the movable cutter member heel and passing through the slot in the bracket, and a helical compression spring surrounding the stud and extending between the bracket and the movable cutter member heel.
2. A thread cutting temple for looms comprising a movable cutter member having a depending heel and mounted to rock vertically and slide longitudinally in the temple, a bracket rigidly supported from the temple and extending in front of the movable cutter member heel and having a vertical slot opposite the said heel, a stud rigid with and projecting forwardly from the said heel and passing through the slot in the bracket, and
a helical compression spring surrounding the stud and extending between the bracket and the heel.
In testimony whereof, I have signed my name to this specification.
ALPHONSE LECOMTE.
