A. P. PAINE TUBE FRAME BRACKET Filed July 19, 1924 Patented Mar. 9, 1926.
-* UNITED STATES PATENT OFFICE.
ARTHUR I. PAINE, OF WORCESTER, MASSACHUSETTS, ASSIGNOR TO CROMPTON KNOWLES LOOM WORKS, OF WORCESTER, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.
v TUBE-FRAME BRACKET.
Application filed .Iuly 19, 1924. Serial No. 727,072.
To aZZw/wmitmay concern: u
Be it known that I, ARTHUR P. PAINE', a citizen of the United'States, residing at Worcester, in the county of lWorcester and State of Massachusetts, haveinvented a new and useful Tube-Frame Bracket, ;of which the following is a specification;
This invention relates to carpet looms of the A'xminster type and more particularly to the brackets by which the yarn .tube frames are supported upon the transporting pattern chains. The length and'weight of the tube frames has been greatly increased within recent years'and the stresses upon the supporting brackets have been correspondingly increased. 4
It is the object of my inventionto provide a tube frame bracket so constructed that it will possess ample strength and that it will firmly hold the tube frameson the transporting chains without the possibility of accidental displacement. My invention further relates to arrange ments and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.
A preferred form of the invention is shown in the drawings, in which Fig. 1 is a front elevation of one end of a tube frame embodying my improvements;
Fig. 2 is an end elevation thereof, and
Fig. 3 is a partial front elevation showing the tube frame bracket detached from the transporting chain.
Referring to the drawings, I have shown a portion of a rectangular tubular member 10 to which a plurality of yarn tubes 11 are firmly secured, preferably by soldering them thereto. My improved bracket com prises a bearing member 12 and a chain engaging member 13. These parts 12 and 13 are preferably welded together in their intermediate portions and may be provided with offset arms 14; extending within the tubular member 10. A plate 15 1s riveted or otherwise secured to the inner side of the engaging member 13 and is bent inwardly at 16 to provide a bearing for a pivot pin 17 on which is mounted an upwardly extending lever or arm 18.
The bearing member 12 forms a support for one end of a yarn spool 20 and is extended upward beyond the spool bearing 21 to form a support 22 for a depending pivoted latch 23. On its under side the latch 23 is recessed at 24 to receive the rounded upper end of the lever 18. The lever 18 is pressed yieldingly outward by a spring 25, causing the latch 23 to engage the ofisetupward extension 26 of they chain engaging member 13. The chain engaging surface of the latch is bevelled and actsfas a cam to force the latch outward. The member-13' is provided with anelongated slot 27 to permit upward passage of the arm 18. p
' The transporting chain is indicated in broken lines at 30: I have also indicated at 31 tlwelld or head of a releasing lever by which the tube frame is detached fromthe chain and is presented to the warp. This lever in itself is of the usual construction and forms no part of my invention, Ijhave, however, extended a bearing stud 32 inward to provide a lug or projection adapted to engage the arm 18 as will be hereinafter described. I
Assuming that the'tube frame is attached to the transporting chains and that the parts are in the position shown in Fig. 1, the head 31 will be moved to theleft, engaging the tube frame and raising the frame slightly from the transporting chains by reason of the cam-shaped lower projection 33 of the head 31. As the frame isthus raised, the lug 32 engages the arm 18, swinging the latch 23 to the position shown in Fig. 3. The head 31 is then lowered to present the tube frame to the warp, after which the movements are reversed and the tube frame is again attached to the chains 30. As soon as the tube frame is released by the head 31, it will be evident that the weight of the tube frame and also the spring 25 act to hold the latch 23 firmly against the projection 26 of the chain-engaging member 13. It will be chain engaging member effective to locate the tube frame laterally and a spool bearing member, both of said members extending above the chain when operatively connected therewith, a depending rigid latch pivoted to the upper part of said spool bearing member, and means to move said latch to operative and inoperative positions relative to the chain.
2. A tube frame bracket comprising a chain engaging member effective to locate the tube frame laterally and a spool bearing member, both of said members extending above the chain when operatively connected therewith, a depending rigid latch pivoted to the upper part of said spool bearing memher, and means to move said latch to positively engage said chain engaging member above said chain, said latch being operatively positioned when thus engaged.
3. A tube frame bracket comprising means to locate the tube frame laterally, a depending chain engaging latch pivoted to said bracket, said latch having a recess in its under surface, a lever having its upper end projecting within said recess and effective to move said latch to operative and inoperative positions, and means to move said lever.
4. A tube frame bracket comprising a chain engaging member effective to locate the tube frame laterally, a spool bearing member having an upward extension, a depending latch pivoted to said extension above the spool bearing and adapted to engage said chain, and an actuating lever engaging said latch and operable to yieldingly move said latch to operative position and to positively move said latch to inoperative position.
5. In a loom, transporting chains, a yarn tube frame having supporting brackets therefor, each bracket comprising a spool bearing member having an upward extension and a depending chain engaging latch pivoted to said extension, and means to move said latch to operative and inoperative positions.
6. In a loom, transporting chains, ayarn tube frame having supporting brackets therefor, each bracket comprising a spool bearing member having an upward extension, and a depending chain engaging latch pivoted to said extension, and means to lift said tube frame from the transporting chains and to thereafter move said latch to inoperative position.
In testimony whereof I have hereunto affixed my signature.
ARTHUR P. PAINE.
