UNITED STATES PATENT OFFICE.
GEORGE J'. PFEIFFER, 0F PROVIDENCE, RHODE ISLAND, ASSIGNOR T0 CROMPTON KNOWLES LOOM WORKS, OF WORCESTER, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.
Application l'ed May 29,
i Thisinventi'on relates to harness connecters for'looms and it is the principal object of lthe invention to provide an all-metal extensible connection quickly adjustable as to length. n n
Looms usually employ harness frames by means of which a group of warp threads may be raised or depressed, and these frames are controlled by a so-called harness mecha-` nism liavving a notched jack or lever. The motion -of the jack is communicated to the which has heretofore usually been `made either ofileather or cord which are subject to stretching, the connection usually passing around a sheave or pulley when leading from l the jack to the frame. It is a further object of my invention to improve upon these connections lby making the same out of flat metallic Astrips which are adj ustably connected together to vary the distance between the harness frame anduthe point of attachment with the harness jack, the metallic construction preventing stretching.
It is a more particular object of my invention to provide a harness connecter of a plurality of metallic strips one of which is provided with a plurality of perforations to receive a projection extending from the other strip, onefof said members being flexible to extend around a sheave or pulley.
A more detailed object of my invention is to provide a harness connecter formed of a pair of relatively inflexible metal end members which are connected to the ends of a flexible metallic strap, said metallir strap being adjustably connected to each of the end members, the interval between adjacent points of attachment between one end of the flexible strap and the corresponding inflexible end members being different from the interval between adjacent points of connection between the other end of the strap and the other end member.
A further object of my invention is to pro vide a metallic stiip formed of a resilient member held to two end members in such a Way that when bent around a harness sheave the natural tendency' of the ends of the flexible strap will be to remain in contact with the end members.
W'ith these and other objects in view which r will appear as the description proceeds, my
invention resides in the combination and ar- LOOM HARNESS-STRAP AGONNEC'IER.
1926. ser'iarit. 1123557.
rangement of parts hereinafter described and set forth in the claim.
In the accompanying drawings wherein I have shown' a convenient embodiment of my invention, Y
Fig. l'is a top plan view of the connecter, parts being broken away,
Figfz is a partial front elevation looking i in the direction 'of arrow 2, Fig. l,
Fig. 3 is a reduceddiagiammati front elevation of certain portions ofthe loom inl` dicati'ng` the manner of usingi'my in'ventio.n
Fig.v Z.tis an end elevatiorioff'the` iclip eni- I ployed to hold adjacent part-s together, I
lfigs. `5 and 6 are enlarged'fvertical sections on'lines 5 5 and 64,6,.re'spectively, of Fig. l, and' i i Fig. 7 is an enlarged front elevation, parts I and maybe provided with he'ddles 18V and have projecting upwardly' therefrom a connecter eye 19. The arches 11. have extending between the same shafts 2O on each of which is rotatably mounted a plurality of harness sheaves 2l. A harness wire 22 having hooked longr and shortl ends 23 and 24, respectively, is connectedA to a jack eye 25 held in one of the notches of the associated harness jack.
' The matter thus far described is of common construction and forms no invention.
In carrying out my improvements I provide a. pair of connectors C for cach frame, one. of said connecters being indicated more particularly in Figs. l and 2 and having the right end thereof formed of a relatively inflexible preferably metallic end member 30 provided with a plurality of key-hole slots 3l so disposed that the narrow parts of the slots point toward the center of the eonnecter. The right hand end of said member 30 has a hole 32 extending therethrough while the left hand end is offset as indicated part of my present llHl The stud'( extendstlnough anyI one of a lplurality of substantially circular holes-.38
.punched through the secoudlinflexible and preferably' metallic end nieniber 39.V Said nxeinber 39 has kthe in'lne'r end` thereof provided with an offset 40. similar to the offset 33 haying tlierein a slot lHand the outer end of themember 39v is provided with a hole42. AI @up 43 indicated in rig. 4, is siidably `{ounted on the member 39fi'and surrounds the latter and also'I the flexible strapI S, beingheld inj pla'cerby; friction. The' intermediate flexible straplporti'onmof theconnecter passesthrough the slots 34 and 4 1 and is held in fixed position relatively to thev end members by the aforesaid studs. It is to be understood vthat if the desired both ends of the connecter may be made as indicated in the right hand end of Fig. llor both ends may be constructed as in'dieatedin the left hand erid'ot'Fig. l.
As indicated in Figs. 3 and 7 there are two connecters for each harness frame, the members 39 beingconneetedto the harness lever 12h32 means of the Wire QQ'and jack eye 25.. The other members .30 are secured to the harness frame hooks; I9 by having,
the latter passed through the'h'ol'es 32.
The length of the connecter may be varied by giving either end member a new setting with respect to thecentral portion. If it is desired to make a relatively large adjustment the member 30 may he moved along the member S imtil the head 36 will pass through the large part oi the key-hole slot after which the stud 35 maybe passed through the next slot. Should it be desired to make a relatively smaller adjustment clip 43 can be moved inwardly along member 39 and the end of the member S sprung away from member 39 to remove the conical stud 37 after which the latter may be moved to the next or any other of the openings 38. The distance between the key-hole slots is greatments, the number of adjustments being" greateu than the sum of the slotsA andthe uolesby reason ofthe factltha't the interval between" thegslot-s is different from ,but notY a multiple of thedistance between ,the h'oles,
ltwill alsozbe seen thatgtl1e2clip 43 is held' against' loss beyond'the: endvof tthe member by means 'ofthestu'd 37. Also as`- shown in 3 is wi'llbe' seen that the ends otthe flexible' member S 'lie on'. the inside ofthe. curvev of' the vconnecter so that said tendsiare held natturally against theendfme'mbers by, the', resil` ience yof the strap. S. It is tov bex understood as previously stated thatth'e 'connecter may have each end provided w'ith afmember 30er' both, ends may be formadas member 39.
Having thus described my invention it will be4 apparent 'that changes (and modifications may be made therein by those skilled in the art Without `departing from the spirit and 'SCOPe .0f the ilVeDtOIl and I" do not wish' to be limited jto the detailsherein disclosed but what I claim' is:
A harness connecter for ra loom having a harness jack, aharness sheave,.and 'a harness frame, said connecter. comprisinga' pair of end members, ,one for the harness jack andl one for the harness frame, a flexible member between the end members, means defining a ,plurality lof .points at which connectionmay be' had between one oi said' end members and the adjacent end of the flexible member, and meansy defining a plurality of points of attachment between the other end member and the other endlofhthe flexible member, the interval between the points of connection. on.
one member beingfother than a multiple of the distance between adjacent points of connection on the other member.
In testimony whereof I have hereunto affixed my signature.
