UNITED STATES 1,52a735 PATENT OFFICE.
HAROLD L. IBLANCHARD, OF WHITINSVILLE, MASSACHUSETTS, ASSIGNOR TO CBOMP- TON & KNOWLES LOOM WORKS, OF WORCESTER, IMASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.
TUBE FRAME.
Application filed November 9, 1923.
To all whom it may concern:
Be it known that I, HAROLD L. BLANCH- ARD, a citizen of the United States, residing at -Whitinsville, in the county of Worcester and State of Massachusetts, have invented a new and useful Tube Frame, of which the following is a specification.
This invention relates to tube frames for Axminster looms and more particularly to an improved means for fastening the brackets or spool bearings to the ends of the tube frames.
One object of my invention is to provide a hollow tubular bar and bracket members with complementarily formed parts, by means of which the tube frame and bracket members are interlocked.
Another object of my invention is to provide a bracket which is very securely fastened to the frame but which may be readily removed thereform without deforming either the tube frame or the bracket.
A more particular object of my invention is to provide a bracket formed of two parts so constructed as to have tube frame engaging ears of one part lying in a plane other than parallel to the ears of the other part, the ears being of varying cross section and arranged to be received by similarly formed gpenings in the walls of the tubular mem- With these and other objects in view, which will appear as the description proceeds, my invention resides in the combination and arrangement of parts hereinafter described and set forth in the claims.
In the drawings wherein one form of my invention is shown,
Fig. 1 is a front elevation of one end of a tube frame having my invention applied thereto,
Fig. 2 is a vertical transverse section taken on line 22 of Fig. 1 and Fig. 3 is a perspective view showing one end of a tube frame and the associated bracket members in the position they assume before assembly.
Referring to the drawings, the body of the tube frame is shown as being formed of a hollow metal bar 10 of polygonal cross section having upper and lower horizontal walls 11 and 12, respectively, and parallel vertical walls 13 and 14, respectively. The yarn tubes 15 are carried by a strip of sheet metal 16 which is substantially L-shaped and en- Serial No. 673,738.
gages the outer faces of walls 12 and 14, the strips being held to the bar in any approved manner as by screws 17. A leaf spring 18 is screwed to the top of the tube frame and has an offset end provided with a friction pad 19 to engage the head 20 of the spool 21 for the purpose of, retarding rotation of the same.
My invention relates more particularly to the formation of the ends of the bar 10 and the two members which together form the bracket or spool bearing. As shown in Fig. 3, the top wall 11 of the bar is provided with an opening 30 the outer end of which is comparatively narrow while the inner end is Wider. Walls 13 and 14 are provided with openings 31 and 32, similar to opening 30, which are preferably in alignment so that they may be stamped out by the same dies.
The spool bearing member 33 is formed at the upper end thereof to receive the gudgeon of the spool 21 and the lower end is provided with a bent ear 34 so formed as to fit snugly in opening 30, that portion of the lower end of the member lying on each side of the ear 34 being arranged to engage the top of the tubular bar as shown in Fig. 1. The chain engaging member 35 has an offset upper tongue 36 received by the chain and has the lower end thereof provided with a pair of ears 3'? and 38, respectively, which are so formed as to fit snugly into openings 31 and 32. The members 33 and 35 are provided with registering holes 39 and 40, respectively.
l/Vhen assembling the bracket the ear 34 is inserted in opening 30 after which the member 35 is positioned-by inserting the ears 37 and 38 in openings 31 and 32, respectively. Screws 41 are then passed through countersunk openings 39 in the outer part of thebracket and into the tapped holes 40, the two members being in this way united to form a rigid bracket.
It will be seen that I have provided an extremely simple bracket which is held to the tube frame in such a way as to resist motion lengthwise of the tube frame, angularly with respect to the tube frame and transversely thereof either vertically or horizontally, while at the same time providing for a very ready means for removing the bracket. It will further be seen that the dovetailing of the ears and the associated openings permits the bracket to be secured to the frame without requiring screws to be threaded into the-hollow frame, and that all the parts can be made of stamped metal.
Vhile I have shown my invention as ap-. plied to a hollow tube, I do not Wish to be limited to such a construction as the bracket could be used with any tube frame having dovetail recesses therein.
It will be observed'thatthe interior of the tubular bar, When the latter is made hollow, is smooth at the ends so that a Wooden core extending-the full lengthfiof the bar can be usedni f desired.
Having described my-invention, it will be evident that: changes and modifications inay be made by'those. skilled in the art without departin gwfrom theaspirit' and scope of the invention as set forth in the appended claimsyand -l do not'wish' to be otherwise limited to the details herein disclosed.
'-"WVl1a-t I claimis P t 1. In 'a tube frame for Axminster looms, a hollowbar polygonal in cross section and having the ends-of adjacent Walls provided with openings having sides oblique with respect-to 'eachother, and a bracket forsaid tubular member having ears extending therefrom "and fitting snuglyin said openings formed in the walls of the hollow bar;
2. Ina" tube frame for 'Axminster looms, a* hollow tubular member polygonal in cross section, apair of bracket forming members securedtogether,one of said members having a dovetail connection with one of the Walls'of said tubular bar and the other member ahaving. dovetailconnection 1 with oppositezwalls of the tubular bar. l
In atube frame for Axminster looms,
a transverse bar extending lengthwise "of the tube frame, a bracket for said bar, and interlocking dovetail connections between the bar andbracket' and formed integrally 'witlrsaid bar and bracket andlyingin' angularly disposed planes to prevent angular,"t'ran'sverse and longitudinal movement of the bracket with respect to the bar.
4. In a tube frame for Axminster looms, a hol ow tubular bar having' adjacent-an gularly disposed.- Walls, a pair of bracket forming members -therefor, one e f-said meme.
berszhavinlg' a dovetailed portion tolie \vithin dovetai eel-openings in one of the walls i of the bar to restrain said member against transverse motion 'W-l-ilhrespect to I the bar in one directlomthe other member having dovetailed portions to lie in dovetailed openings in other Walls-of the bar to restrain transverse motion. with respect. to the bar in another direction, and means to secure said members-together to form' abracket which is restrained 'against transverse -n'iotion with respect: to the tubular bar in any direction:
5. In a tube frame for Axminster looms. a bar polygonal in cross-sectiom-a pair or? bracket forming members,'ears formed on said members and received formed in the bar to define dovetail conned tions between'the-bar and the members, and means to secure thememberstogether, said dovetail connections forming the only connection betWe'en'the barand'the members.
