BEAM-LOCKING DEVICE FOR LOOMS.

1,312,269. Specification 0 Application filed November To all whom it may concern:

Be it known that I, ALONZO E. RHoADEs, a citizen of the United States, residing at Hopedale,county of Worcester, State of Massachusetts, have invented an Improvement in Beam-Locking Devices 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 improvements in beam-locking mechanism for looms and the object thereof is to provide a simple and effective construction which will permit the beam shaft to be quickly introduced into its bearings in the loom sides and effectively locked therein.

In the usual loom construction the shaft of the warp beam is journaled in open bearings in the loom sides and is usually held up. This is undesirable because of the effect upon the tension of the warp and consequently upon the cloth being woven.

The present inventionis designed to provide for more securely retaining the beam beam shaft in proper position and to reduce the wear of the journals and ournal bearings.

This is accomplished by providing the loom sides with alined journal bearings,having openings in their walls to permitthe introduction of thebeamshaft, of less width than the diameter of the bearings, equipping the greater 1 diameter than the said shaft andcompleshaft with journals of mentary to said journal bearings, so that the beam shaft maybe inserted sidewise into the hearings in the loom sides and the journals upon said shaft then inserted end wise into the journal. bearings. It will be obvious that when the journals upon the shaft are thus inserted their diameter, be-

ing greater than the width of'the aperture inthejournal bearings, willprevent the removal of the shaft whilepermitting their own rotation in the bearings. a The further object of the inventionis to provide a beam lock ofthe oharaster-gabove f Letters Patent. Patented Aug. 5, 1919.

described, which may be applied to the usual type of loom without material modification. lhis is accomplished in the present invention by providing brackets to be secured to the loom sides with journal bearings of the character above described, so that when the bracketsare secured tothe loom side, with the journals in axial alinement with the usual journals or seats in the loom sides, the shaft of the warp beam may be readily in troduced into the bearings and locked therein by suitable ournals slidably mounted upon the beam shaft and adapted to be inserted endwise into the journalbearings of the brackets. y

A further feature of the invention consists in providing means whereby the bracket with the complementary journal bearing may be adjusted so that n0 difliculty ment between the journal bearing of the bracket and the usual journal bearing in the loom side, the adjustment further permitting the taking up of any play in the bear ing which may occur by reason of the wearing of journal or journal bearing.

Other objects and features of the invention will more fullyappear from the following descriptions and accompanying drawingsand will be pointed out in the annexed claims. j

Fig. 2 is a rear elevation of a portion of the loom side, one end of the warp beam and its shaft and the means of locking the shaft in the loom side. i

Fig. 3 is a detail view of the preferred form of bracket, having a journal bearing for the beamshaft and an aperture in its wall to permit the introduction of the shaft.

Fig. & is a detail view of the bracket having a journal bearing of the character The 10am structure to which the present will be experienced in causing axial alineshown in Fig. 3, and showing the beam invention" is applied maybe used in the usual character, com rising loom sides 1, 2 htIVHlg'GXtGHSlODS W nch provide shoulders 3, whichhave the usual sockets 4: to receive shaft 8 which is adapted to rest at its ends inlthe journal bearing 5 in the loom sides.

' The warpi9 from the warp beamis carried th eiusual manner.

, overvthe usual Whip roll 10 to the shed in Means are provided for permitting the introduction of the shaft into its bearing and for locking the shaft in said bearing ,by mechanism upon or carried by the shaft itself. In the preferred embodiment of the invention disclosed herein, the journal bearngs for the. shaft are made larger than the diameter ,of the shaft and their walls are provided with apertures through which the shaft may be introduced into the bearings. The shaft is provided with a jour vnal of larger diameter than the shaft and complementary to the journal bearing. Means are provlded for permitting end-wise movement of the ournals upon the shaft to enablethem to be fitted into the journal v bearings, since thejournal upon the shaft is of greater diameter than the opening through which the shaft is introduced sidewise into the bearing.

It will be understood that journal bearings of this character may be formed directly in the loom sides but preferably are carried by brackets adapted to be secured to the loom sides andhaving journal bearings of greater diameter than the shaft adapted to be placed in axial alinement with the usual hearings in the loom sides.

aside the opening 17 lies opposite the open portion of'the-usual journal bearing in the doom side so;thati,the:shaft may be introduced into the bearings in the usual manner.

Inthepreferred embodiment of the invention disclosed in the accompanying drawings, a bracketll is adjustably secured to each loom side by a bolt 12 passing through a slot 'in said bracket, and a suitable aperture in the loom side. The bracket llhas a lateral extension 1 1 provided with a cylindrical boss 15 forminga journal bearing 16.

A portion of the wall of the boss 15 is cut away .to form anaperturel'? of slightly greater w-iidththan the diameter of the shaft 1 8. lVhen the bracket is secured to the loom The journal bearing 16 in the bracket 11 ,is of considerably larger diameter than the diameter of the shaft 8, and in the preferred embodiment of the invention the shaft is supported Within the bearing 16 by a journal 18: carriedbythe shafts and adapted to be.

inserted endwise into the journal bearing 16. It will be obvious that when the journal 18 is inserted in the journal 16 the shaft will be prevented from removal from said bearing because the journal 18 is of too large a diameter to pass through the opening 17 through which the shaft was introduced.

The journal 18 desirably is in the form of a split sleeve, having lateral extensions 1$) 20, secured together by bolts or screws 21, so that the sleeve may be clamped upon the shaft 8. By reason of this construction the loosening of the screws 21 will permit the sleeve to slide along the shaft so that it may be readily inserted endwise into the journal bearing 16. hen the screws 21 are set up they will lock the sleeve upon the shaft with V the journal 18 properly mounted within the journal bearing 16. When the parts are thus assembled at both ends of the shaft any endwise movement of the shaft during the rotation of the warp beam will be prevented, since such end-wise movement would cause the end 22 of one of the bosses 15 to come in contact with a shoulder 23 upon one of the extensions 19 of said split sleeves.

In the preferred construction the journals 18 are adjustably secured upon the shaft 8 at both ends. but it will be obvious that if dcsirable an enlarged journal complementary to the journal bearing 16 may be permanently secured to or made integral with the shaft 8 and introduced into the journal bear- 1 ing 16 by endwise movement of the shaft. :In new, however, of the heavy weight of and means carried by said shaft operable to prevent removal of the shaft from said ournal bearings.
