Dorila Demeul e DORILA DEMEULE, or MANCHESTER,
NEW HAMPSHIRE, ASSIGNOR TO DRAPER CORPORATION, OF HOPEDALE, MASSACHUSETTS, A CORPORATION OF MAINE.
PROTECTOR-ROD HOLDER FOR LOOMS.
Specification of Letters Patent.
Patented Feb. 24, 1920.
Application filed August 15, 1918. Serial No. 250,052.
To all whom it may concern Be it known that I, DORILA DEMEULE, a citizen of the United States, and resident of Manchester, county of Hillsborough, State of New Hampshire, have invented an Improvement in Protector-Rod Holders for Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.
This invention relates to journal brackets for looms and the object thereof is to provide a journal bracket of a character which may be secured firmly to a part of the loom and which will not become loosened and dis engaged by the vibration of the loom or the part to which the bracket is attached.
More specifically the invention comprises improvements in brackets for supporting the protector rod of the loom from the lay. The brackets which have been heretofore generally used for supporting the protector rods from the lay have comprised L-shaped plates having downwardly extending bosses providing journals for the protector shaft, said L-shaped plates being secured to the lay by screws extending into the back face and bottom of the lay respectively.
The Vibration of the lay and the shock caused by the operation of the protector mechanism in time loosens the screws which thus attach the bracket to the lay and render the support for the protector shaft inoperative. The present invention contemplates the production of a journal bracket for the protector rod of a loom which can be so securely fastened to the lay that it will not be loosened by the vibration of the lay or the shock occasioned by the operation of the protector mechanism.
This is accomplished in the preferred embodiment of the invention disclosed herein by providing a bracket comprising two members, one of L-shaped form adapted to fit one face and bottom of the lay and having a downwardly extending boss providing a journal for the protector rod and a second member hinged to the free edge of the portion of the L-shaped member which engages the bottom of the lay, said hinged member being adapted to engage the-oppositeface of the lay. The bracket formed by these members is secured to the lay by a bolt passing through the lay and the members applied to the lay of the bracket which engage the faces of the lay and the nut on the bolt locked so that it cannot be unscrewed by shock or vibration.
t will be understood that while the invention herein disclosed is particularly applicable to journal brackets for supporting the protecting rods of looms it is capable of use in other relations' A further feature of the invention consists in providing a journal bracket of the class d scribed with means for anchoring the end of a spring for controlling the action of the protector rod.
Other features of the invention will more fully appear from the following description and the accompanying drawings and will be pointed out in the annexed claims.
The drawings illustrate my invention as of a loom of the usual Northrop type.
In the drawings;
Figure l is an elevation of the rear side of the lay of a 100m showing a portion of one of the swords for supporting the same and a protector rod journaled in a journal bracket embodying my invention,
Fig. 2 is a detail View of the rear portion of a'lay showing the manner in which the journal bracket for the protector, rod is secured to the lay,
Fig. 3 is a transverse sectional view through the lay showing the journal bracket for the protecting rod bolted to the lay, and
Fig. 4 is a detail view on line M, Fig. 3, showing the downwardly extending journal in central vertical section.
Inasmuch as the preferred embodiment of the invention is disclosed as applied to the journal brackets for supporting the protector rod of a loom only a sufiicient portion of the loom is illustrated as is necessary to show the application of the present invention thereto. It will be understood that the portion of the loom so illustrated herein comprises the usual parts of the well known Northrop automatic filling replenishing loom.
As illustrated in Fig. 1 the usual lay 1 which is carried by the sword 2 terminates in a shuttle box 3 having a rear binder 4 which is engaged by the arm 5 of the protector mechanism, said arm 5 being secured to the offset end 6 of the protector rod 7 the of the L-shaped plate which engages the which may be mounted in suitable journals carried by the .sword 2 and in one or more other journal brackets 8 secured to the lay of the loom.
he present invention comprises a journal bracket consisting of two members one of which is an L-shaped plate having a base portion 9 adapted to engage the bottom of the lay and a vertical portion 10 extending upwardly therefrom adapted to fit the back a face of the lay.
A downwardly extending boss 11 is apertured to form a journal 12 for the protector shaft 7. The downwardly extending boss is also provided with a groove or recess 13 adapted to receive and anchor the end of the helical spring let which controls the movement of the protector rod, the oppositeend of the spring 14 being anchored in a collar 15 whlch is secured to the protectorrod 7 by a set screw 16.
prises a plate 19 having at its lower end bosses 20, which are apertured to receive the pintle 18 so that m effect the member 19 of bracket is hinged to the free lower edge bottom and back of the lay.
The portion 10 of the L-shaped member is provided at a desirable distance above the bottom with an aperture 21 which may be provided wlth a countersink 22 to receive 1 the head of the bolt 23, said bolt passing through the vertical portion 10 of the L- shaped member, entirely through the lay in parallelism with the bottom thereof and through a vertical slot 24 in the hinged member of the bracket. The bolt 23 is provided. with the usual nut 25 which may be secured from withdrawal in any suitable.
manner, as for example, by a cotter pin 26 passing through the bolt adjacent the outer face of the nut.
By reason of this construction the journal bracket is so securely fastened to the lay that it 021111106 be loosened either by the vi bration of the lay or by the shock imparted when the dagger carried by the protector rod engages .and operates theusual mechanism for knocking off the loom.
It will be understood that the embodiment of the invention disclosed herein is illustrative and that various changes in.
form, arrangement and construction of parts may be made within the meaning and scolpe of the following claims. 1
aving thus described my invention what I claim as new and desire to secure by Letters Patent is: 7
1. In a loom comprislng a layhaving a protector rod extendlng along the same,
means for. supporting said protector rod in- V eluding a bracket having an L-shaped member engaging one. face andthe bottom of said lay and a. member hinged to'the lower free edge of said L-shaped member engaging the opposite face of said lay and a bolt passing through said lay and the members of saidbracket which engage said'opposite faces of the lay, thereby securing the bracket firmly to said lay. V-
2.'In a loom comprising a lay and having protecting mechanism including a protector rod extending along the bottom' of said lay, a ournal bracket for said protector rod comprising an L-shaped member adapted to embrace and fit one face and the bottom of said lay and a member hinged to the lower free edge of said L-shaped member engaging the .other face of said lay, a .bolt passing through said lay from face to face and, through both face engaging members of said bracket, the bearing for I said protector rod comprising a boss formed inte- "gral with said L-shaped member and dependmg therefrom and havmga recess to provide an anchorage for a helical spring encircling said protector rod and anchored at its opposite end to a suitable collar secured to said rod. v
In testimony whereof, I have signed my name to this specification.
