To cir/ZZ whom it may concern,.-

Beit known that l, HENRY W. LAnssoN, a citizen of the United States of America, and

a resident of Springfield, in thev county of Hampden and State of Massachusetts, have invented certain new and useful improvements in Branding-Machines, of which the following isa full, clear, and exact description.

vThis invention relates to improvements in braiding-machines of a type in which there are two sets of bobbins and carriers therefor revolved in oppositevdirections and a threadguidc for alternately moving the thread 'from one set of bobbins to opposite sides ot the threads running from the other set ol bobbins, whereby the proper disposition of the threadslor laying them in 'for plaiting or braiding is accomplished.

The objects of this invention are to nroduce a braiding-machine ot a simplified c -araoter susceptible oi being constructed on approved mechanical principles, one in which there is necessary but a minimum of parte, and which in operation is almost noiseless, because ol2 the easv motions produced therein, and one in which a maximum number ot hobbins and correspondingly-increased amount of thread may be carried at an unusually high speed, whereby the productiveness oi the machine is unusually large.

The invention consists in constructions and organizations ot parts, all substantially as hereinai ter fully described, and forth in the claims.

The improved braiding-machine is illustrated in the accornpanyingjT drawings, in which- Figure l is a central vertical sectional view of the complete machine. Fig. 2 is a plan view ot the under side ot one oi the individual devices comprised in the machine, hereinafter more particularly referred to. Fig. 3 is a plan view of the machine as seen below. the annular cap, certain parts being broken away to disclose positively certain ot the details of construction. F 4 is a horizontal sectional view as taken on the line 4 Ll, Fig, l, showing, mostly in plan view, the parts below such 4plane of section. Fig. 5 is a vertical sectional view, on a very much enlarged scale, of the operating mechanism for one of the duplicated thread-carriers, Fig. 6 being a front elevation of the same as seen at right angles thereto.

l i l l l i l l Similar characters of reference indicate corresponding,` parts in all ot the views.

` ln the drawings, A represents a standard ot circular form constructed hollow having concentrically at its upper end a tubular extension o, fitted on which is a sleeve or bushing l ,which constitutes the-hub for a spur gearwheel c and having 'formed on or attached to it a large spur gear-wheel d.

B may be termed the "'powelr-shaht,J the 6 same being vertically Viournaled within ti e standard A, having at its upper end .a spurpinion f, which meshes into lthe aforementioned spur gear-wheel c, and having 'fixed thereon next thereunder slightly-smaller vo spur-pinion which through an intermediate spur-'pinion g? has a driving engagement with an internal gear-wheel it, located within a cup-shaped portion oi" an annular hotly D, which is iitted and supported for rotation 75 about and upon the cylindrical standard the latter havin;y the supper said annular body. A' power-strait it is provi. lO, ineshin .into whl carried the dri,

L) e `tor holders lor tf and vfor movaoie guides or ce threads of such hohhins l mechanisms which respecti successive inward and o i ments to said carriers d'.

ln the outer portion oi' the upper entremity oi the annular bodyr ift-which, shown, is of a double-step form, is an upwardly-opening annular channel or racewa;T H', in which are closely 'titted `for sliding movements the blocks i i, which constitute the bases ot the carriers L tor the second set -o't hobbins 2, this latter set therefore, as seen, being arranged vtor revolnble motions at an upper roo part of the ina-chine, while the aforementioned set of bobbins l, carried by the rotatable annular body il, aredisposed in a considerably lower plane.

Each of the blocks or bases i, of the bobbincarriers ll, which is ot arc shape 'to conform to the `annular ra'cewajf ll therefor, is provided with inwardly-disposed rack-teeth j, inwardly and concer trically disposed within which and rotatable in a common horizontal i ro '15o t-he upper set of bobbins.

plane are a series of spurinions m m, the axis shafts or studs there or and on which they are aiiixed having vertical ournal-bearf y ings through the upper and outwardly-flan ed portion of the annular body D, next wit 'n the rack-'toothed loObbn-carer bases, and all'of the said pinions m are in constant mesh with the aforementioned comparatively large spur gear-wheel d, which, as shown and may 'xo be `discerned from ,its driving ,connections i 5 will be caused to move, following each other .around'ina Jhorizontal circular path in a reversed direction to that of the movement ofA said annular body-that is-to say, when the machinev is running the lower set ofbobbins 1 2o` will have their 4 revoluble movements in la i j circular path in the direction of the arrow, Fig. 4,- while theupper set of bobbins 2 will have their -revolub'le movements in the circular path in the direction ofthe outer arrow z5 shownoniig. 3. Y

. The sets o equally-spaced pinions m m are in such proxinut and the relative lengths of the racks'j on t e bobbin-carriers are such -that suchracks 'Will never be out of engagement with some pair oi the pinions m.

upper and lower sets of bobbins are, iii-' the machines as lll'have designed it and as it is here shown, of about equal diameter. Supported as an ext'ension'oi the u standing tubular portion a of the cylindrica standard is a tubular neck 7c, having an annular flange lez marginally upwardly rounded',-as indicated at lcs, overwhich all of the threads from both sets of bobbins 1 and 2 pass and are vconvergentlyinwardly continued to the axial ,center of the machine, where they constitute the plaiting or braiding, such threads under the operation of the machine alternately 4'5 crossing each other at the outer smooth surface of this'part 1c c2 lc, which may be termed the cap.. As shown, the periphery 'oi' the 'thread-supportingcap is in substantial vertical alinement with thel path of movement of By this construction all oi' the threads have a common support 'concentric to the point ,where the braid is formed. Hence that-portion of the `thread which'liesbetween the edge or periphery of 5-'5 the cap and the braiding-point remains in the same plane, regardless of the movement oi the thread-carriers, thus insuring 4an even braiding. Furthermore, the thread between the cap and the bobbins extends substantially vertically, that from 'thethread-carriers varying but slightly from thisposi'tion, sothat but a minimumquantity of the thread ismaintained unsupported, espcialiy as the cap' hes inv proximity to the bo ins, thereb forming a sharp angle between the thre'a s per end a spurinion r.
