LOOM.

Specification of Letters Patent.

Patented Nov. 2, 1909.

Application filed April 21, 1908. Serial No. 428,349.

To ail A'whom it may concern:

Be it known that l, JOHN NAZARIAN, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Looms, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in looms and refers more particularly to a counter mechanism actuated by the pick wheel for indicating' t-he linear measurement of the woven fabric whereby the operator or attendant may readily ascertain at a glance the exact quantity of fabric reeled upon the take up roller.

The pick wheel which is commonly employed in looms is provided with a number of teeth corresponding to the number of threads or fillers per inch in the fabric, and is actuated intermittently one tooth at a time by a suitable eccentric, pitman or pawl as each iiller is inserted through the warp by the shuttles in the manner well known and not necessary to herein illustrate or describe, different pick wheels being employed according to the number of threads or iillers required per inch of the fabric.

My main object is to provide a simple, and practical counter mechanism actuated directly by the pick wheel at each revolution thereof to indicate the linear measurement in inches and yards or similar denomination of the woven fabric as it is wound upon the take up reel, not shown.

Another objectis to provide for the horizontal and vertical. adjustment of the counter mechanism to conform to the position of the actuating member thereon and also to conform to different sizes of pick wheels A still further objectis to provide means for releasing the counter mechanism so that it may be revolved in either direction for resetting when desired.

A still further object is to provide for the adjustment of the actuating member of the pick wheel to conform to the position of the coacting member of the counting mechanism.

Other objects and uses will be brought out in the following description.

ln the drawings-Figures l and 2 are respectively front and side elevations of a pick wheel and my improved counter mechanism associated therewith. Fig. 3 is an enlarged interior face view of the counter mechanism and its inclosing case. Fig. 4 is a sectional view taken on line 4 4, Fig. l. Fig. 5 is an enlarged sectional view taken on line 5-5, Fig. 2.

Tn order to clearly demonstrate the practicability and operation of my invention I have shown the usual ratchet or pick wheel -1- of a loom as provided with a number of teeth corresponding to the number of threads or fillers per inch in the woven fabric, said ratchet or pick wheel being rotated one tooth space at a time as each filler is woven into the fabric in the manner well known, said pick wheel being actuated intermittingly in the manner described by the usual pawl 2- and eccentric -3-.

The pick wheel -land counter mechanism presently described are mounted upon a suitable support 4- forming a part of the main supporting frame of the loom, the greater portion of the counter mechanism beingl arranged within a suitable inclosing case c-H which in turn is adjustably mounted upon an upright ariii or bracket -5, the latter being adjustably mounted upon a horizontally projecting arm "6- on the support *4ip A clamp -7- is adjustably secured to one of the spokes of the pick wheel 1- as best seen in Figs. 2 and 5 and comprises essentially two clamping jaws -8- and 9*- engaging opposite faces of the spoke and hinged together at 10- at one side of said spoke while the opposite ends are drawn together by a clamping screw l1- at the opposite side of the spoke as best seen in Fig. 2, said clamping screw also forming a pivot for an actuating member Q for the counter mechanism.

The actuating member l2- is mounted upon one end of the -lever 13- which is pivoted at its opposite end upon the pivotal bolt- -1l-, so that by loosening the clamping bolt the lever with the actuating member thereon may be adjusted around the pivot to the 4desired position or thrown out of action whenever desired and clamped in its adjusted position by a clamping nut -14- which also serves to frictionally engage the jaws -S- and 9m against opposite faces of the spoke of the pick wheel -l-.

By removing the clamping nut -14-, the jaws may be rocked apart upon their pivot e-lO- and reclamped upon any one of the other spokes, the clamping means also serving to permit the adjustment of the actuating member radially along said spoke,

At each revolution of the pick wheel -l-, the actuating member Q* is moved into engagement with one end l5m of a push rod ML which is guided in snitable bearings 17- Within and preferably upon tl e bottom of the casing said. push rod being actuated inivardly against the action of a spring H18-, the latter being interposed between a shoulder --19 on the push rod -ltand the adjacent bearing M1- A Weighted paivl or dog 20m is pivoted at 21M to the inner end of the push rod -1G and yielding-ly held in engagement with one of the teeth of a ratchet Wheel -22- having a certain number of in this instance thirty six teeth and is secured to or formed integral with a comparatively small. gear or pinion 23 having a predetermined number of in this instance l2-- teeth.

The ratchet Wheel -22- and pinion are coaxial and are secured to a shaft or spindle *24e- Which is `iournaled in the front and rear sides of the casing m1 and carries at its front end an exterior hand or indicating finger the latter being movable around a dial 2G-- having a predetermined number of in this instance thirty six graduations corresponding to the number of teeth on the ratchet Wheel At each revolution of the pick Wheel -l-, the actuating member lll-M engages the h ead hdl5- of the. plunger "1G-- thereby forcing the latter inwardly against the action of the spring -18- a su'll'icient distance to cause the pawl -20 to rotate the ratchet Wheel J22- one tooth space in the direction indicated by arronv tru and produces a similar movement of the indicator finger -Q5 one graduation space around the dial -2tS-, each space indicating one inch of Woven fabric; that is each revolution of the pick Wheel -l indicates the number of threads per inch which has been Woven and this one inch linear measurement of the fabric is visually indicated on the dial Q(S- by the finger The pinion 23h meshes with a someivhat larger gear 2?- having a predetermined number of in this instance thirty six teeth and rigidly secured to or formed integral vvith this gear and coaxial therewith is a somewhatl smaller pinion -28- having a predetermined number of in this instance twelve teeth, said pinion -28- and gear 27- being journaled upon a spindle Q9 which supported upon a cross bar -30- and extending from side to side of the casing *5- and secured thereto.

The pinion 28- meshes with a somewhat larger gear d31- having a predetermined number of in this instance twenty four teeth and rigidly secured to this gear -3l.-- is a pinion 52- having a predetermined number of in this instance six teeth, said gear 31 and gear H82-- being coaxial and are secured upon a suitable spindle *233- n'hich is secured upon a bar --Btsimilar to the bar -30 and secured to the main supporting frame or case The pinion 32- meshes with a comparatively large gear M35- which is loosely mounted upon the spindle --Bland is, therefore, coaxial with the ratchet wheel It will be noted from the foregoing description that by proportioning the gears and pinions in the manner previously described, each revolution of the ratchet wheel 22- Will 'anse the movement of the gear one tooth space, said gear 3.3- extending across the inner side of a sight opening` -39 and is provided upon itsI front face with a circular row of consecutive numerals numbering in this instance from l to (30 although any other number may be employed.

l. have described that at each revolution of the pick Wheel which indicates the number of fillers or ivoof to the inch ot fabric Woven causes the intern'iitting rotation of the ratchet Wheel -*22- one tooth space through the medium of the plunger' 16h and paivl -QO- and in vien' of the fact that there are thirty six teeth in this ratchet Wheel m22-, its complete rotation would indicate thirty six revolutions of the pick wheel and, therefore. represents thirty six inches or one yard of woven fabric with a predetermined number of lillers or threads to the inclnsuch measurement being indicated by the complete revolution of the indicator tinger around the dial -Qt3-.

rlhe train of gearing transmitting motion from. the ratchet Wheel -22- to the coaxial gear -35- is such that each complete revolution of the gear --Q-ifscauses the movement of the gear ---BS* one tooth space and inasmuch as there are in this instance sixty teeth and sixty corresponding consecutive numerals upon this gear, the latter moving successively into registration with the sight opening 39* and each numeral indicates a yard7 it is evident that the exact linear nieasnrement of the woven fabric may be ascertained at a glance at any period in the process of Weaving.

if at any time it is desired to stop the counter mechanism while the loom is in action this may be done by loosening the clamping nut -l4i and turning the actuating member -l2- about the axis of the pivot ll-- to throiv said actuating meinber out of ope lattive registration of the head 15- of the plunger -16- where it may be reclamped by tightening the clamping nut .I provide means as a hand operated plunger 55- guided in a suitable aperture in the bottom of the case -aand having its up- In order that the head -15- of the plunper end resting against the under side of the ger -16- may be properly registered to bring it into the path of movement of the actuating member -12- on the t pick wheel -1-, the casing -5- is adjustable vertically upon the support 5- which is also adjustable horizontally upon the support -G- and for this purpose I provide a two member clamping device consisting of upright bars -40- having registering vertical slots 4lthrough which are passed clamping bolts -42-, the latter being secured into the back of the casing -,-5- and extended through the slots 4lwhere they are engaged by suitable clamping nuts -43- to firmly draw the casing against the adjacent face of the support -5- and frictionally hold it in its adjusted position.

The lower ends of the upright bars ACO- forming the supporting frame Tiare deflected laterally in opposite directions and their extremities are then returned inwardly toward each other forming shoulders which interlock with opposite flanges on the support -G upon which the lower end of the bracket c3- is clamped by a suitable bolt -ft4t, and nut B5-1 the bolt passing through a suitable aperture in the base of the bracket -5-.

The upright arm or bracket -5- together with the inclosing case for the counter mechanism are adjustable horizontally along the support -G-, the base of the support -5- being frictionally clamped to said support 6 by the bolt #a4- and nut -15- while the inclosing casing for the counter mechanism is adjustable Vvertically upon the support -5 and is held in its adjusted position by the clamping bolts 44- and nuts -4e5- thus permitting the head -15- of the plunger -lG- to be properly adjusted relatively to the actuating member 1Q- Lvalthough this actuating member and clamp 7 upon which it is mounted may be adjusted radially upon one of the spokes if desired.

The ratchet wheel -22- and train of gearing driven thereby are held from undue vibration or movement. after each operation by the plunger 16- and pawl 20e by a roller detent ,-50- which is mounted upon the inner end of a supporting arm -51- and engages the teeth of the ratchet wheel -22-, said supporting arm --51- being pivoted at 53 to one side of the casing and is drawn downwardly to yieldingly hold the roller against the ratchet wheel by a spring -54 as best seen in Fig. 3.

ln order that the entire counter mechanism may be revolved in either direction freely for the purpose of resetting the same,

weighted end of the pawl -20-, the lower end of the plunger -55- being exposed and provided with a suitable hand piece whereby it may be elevated to force the bit of the pawl -i0- out of engagement with the teeth of the ratchet wheel -22-, it being` understood that the pawl #20- and plunger 1G- are free to move relatively to the lifting plunger 5S- the weighted end of the plunger simply resting and adapted to slide upon the upper face of said plun- Oer What I claim is: A
