y This invention relates to fallenbmrs for gill-drawing frames and particularly to i1nprovenients in the construction "oftheirtteeth or pins and the method of applying them to and holding them int-heba'rs.
A principal object of the invention isto provide a faller-barhaving a novel and lli'lproved type of pin Which-may be more conveniently applied to the bar to reduceits costoi manufacture. V
Another objectiof the invention is to provide %1;fc1 ll83f-l)fl1i1l, Whichthepins are held in exact alineinent and accurately spaced the 'properdistance. apart. f
Another object of thefinvention is to pro- .vide afaller bar which is stronger and less liable to be bent or buckled in use and in which the pins are held more rigidly.
Another object of the invention is to providea faller-har which is more convenient to repair by replacing one or more of its pins Without requiring the removal and replacement of all of the pins. v
Further objects of the improvement are set forth in the iollowingspecification. which describes a preferred form ofconst-ructin of the invention as illustrated by the accompanying drawings. "Injthe drawings F ig. l is a side View. of the improved fallen-bar illustrated with .its central portion broken away; Fig. 2 is an enlarged side view of an .end portion of the barpshoivingit partly in sec- .tion to illustratethe method ofsecurin'g the pinstherein; v p

{As illustrated in Fig. 1, the barfl nay be tions. 3 which engage with the threads of the gill-screws employed for traversingthe bars in the gill draiving frame. The main or bridge portion 40f the bar which extends between the ends 3 ofnarroWer Width and provided with a series of teeth or pins 5 projecting above its top. In the construction of taller-bars used for drawingysilk and other fine fibers the pins are made relatively fine and setclose together, pwhereas ior coarser inaterials the pinsaredarger and heavier. In order toy-attain gthegclose spacing otthe pins for fine- Workit has heretofore been the practice to make: the pins fiat-sided, or more or. less spear-shaped, to provide sufficient. strength to preventthem from bending 01- breaking. l/vith this type otfiat pins the piroblemof setting and securing thein in place in the bar, has been a ,diflicult oneand previous to the presentinventlon no. satisfactory form of construction has been devised for this purpose. The flat or ovalshaped shank or butt of thepin -obviously cannot-be held rigidlyjin 'a"round hole, so that usually pins of-this type-"are set intoa recessorislotonthe side of-the bar and then: soldered 'in -place by flowing "the solder overt-he pins. W'ith this method of conventional form with enlarged end porof setting the pins-in the-hars it hasbeen found extremely difiicult to holdl-the pins-in aline nent and to "space -them a accurately along the top of the ban Wltli-10li11d' pins,
such as used on'theheavier-bars for coarse 'Work, this condition does notobtain because "the cylindrical shanks of the -r0undp1ns maybe driven into d rilled holes in'the bar proved type o-fpin having a novel-construc- 'tion embodying acylindrical shanlt-or-butt end and a flat-sided tapered portionj forining ing a cylindrical shank f)" and an upper 'fiatsided tapered bladei more or less -like'j the pins in the faller bar Ihave devised-an "ln'h shapeot a dagger or ponia'rd. As shown more particularly in Figs and 5, the
.pinsin place.-
the
bridge portion 4 of the taller 2 is drilled with a series of cylindrical I holes 8 -,while the under part ofthe bar is scored orfmilled out with a rectangular ,slot 9. With"th'is" construction the -cylindric'al shanks fi of the pins 5. may be rigidly held in the drilled holes 8, and after the-pins"havebeen properly positioned, older or. the equi lent is p d in o the slot to "anchor the It is of course the pins be properly placed in thefbar with their fiat .sidesin opposed relation,.and to provide for convenience. and facility in setting" the pins in this mammal make use of la fixture or gaugebar 10 as illustrated inEigsi. 7 and Sof the drawings. i The 10 consists si n plyof a strip of metal, usually bronzcfor :brass,fof rectangular cross-section and of a length corresponding. substantially with the lengthof theffaller-bar. In the gauge bar or fixture. 10 Ifprovide a series of flat-sided holes '11 corresponding in size and shape to the blade portions of the pins 5 :adjacent point where they merge into the cylindrical shanks 6, .In filling the taller-bar .2 with the pins,5 the l lattenare picked up in the fingers either singly or in groups and their cylindrical, shanks. 6 inserted I into the round holes 8 in the bridge-portion 4 ofithe bar. H The shanks 6 of the pins fit the holes .8 freely, but, Without play, and the pins will 'dropdown into, the bar :until their widened blade portions strike against the points "of; the pins 5 to enter them into the flattened holes 11; therein. Now as the gauge bar 10 is brought into place against.
the top of the faller-bar 2, inthe position i passing through the;correspondinglfshaped holes 11 in ;the =b,ar1 -,10*will be turnedeor I I rotated to cause'kthem to registerin proper relationto each other,,landalso to maintain them ,in; exact 'alinemcntgwith "an accurate spacing between.their-blades; With the pins held in register and positively, spaced and-alined in this manner, the bar-2 and the V -gauge'lQ;ar e reversed in position as illustratedin ,-Eig.;8; and solderis then poured into theslot or recess 9.1 WVhen' thev solder hashardened the pins 5 will be fixedly anchored in place with their shanks fisheldrigidly and securely-in the holes-8 .ofthe; bar.
- VViththe abovedescribed construction the J away the cross section ,of the bar 01110118 ide thereof as is the common pract ce, with pins are heldiin the bar in exaicta-linement ,with" accurate spacing therebetweeh as reaquired to provide for the maximum efliciency of operation. In other words, the pins may I Ail beset in the bar as accurately as round pins, while at the same time the novel form of the pins provides the advantageous features of flat pins. "This accuracy of spacing and exactltude of alincment is most important to insure. good .work in processing the fibers in the drawing frame. In certain classes of drawing two series of bars are employed with the pins from one set of bars projecting upwardly and those from the other set pointing downwardly between the pins of the lower bars."*Therefore, if the pins are not accuratelyspaced and held in true alincment thefpinsf on the opposed bars will strike "against one another, causing them to be bent orbroken ,and"thus interfering with the proper-operation of the machine. 7 Moreover, with the improved type of pin as. herein illustrated the sides of the pins are arranged in substantially parallel relation so that the spacing between the pine is practically uni- 1 form at top and bottom. This provides that the fibers will nottendtoride up out of the pins; That 1s, the pins'will comb through the fibers without tending. to liftand force the material upward because the space be-.
tween the'fpins is not tapered or narrowed away from their points. i i
7 It will thus be seen that with the present improvement I obtain all the advantages of fthev ilatitype of pin without the disadvan- 'tagesv and'difiiculties inherent to the setting of the latter in the bar'g In fact, with the present improvement the setting of the pins is made especially convenicnt'and easy to acjcomplishand a'much improved czonstructionv of the complete bar is attained. This not only makes for more economical cost of man ,ufactur'e in the first instance, but also renders the] bar easier and cheaper to repair.
For example, if one or more of the pins becomes bent or broken they may be readily asshown ingFig. 8, the bladesolof the. pins 5 will accommodate, themselves to, the -holes11in the-bar 10. Inother words, the flat blade portions of the ,pins 5 in driven out from theholes in thebar and replaced withnew. ones Without removing the wholefseries of pins, as is necessary with poured into the recess of the bar. With the present improved arrangement the individual pins. may be driven out of their holes,
replaced with new pins, and the solder sim ply touched witha heatediron to anchor the new pins in place. .v
It will also be noted that with my' improved faller the main portion of the bar. is not cut awayor weakened to any considerable extent. Instead of slotting. or cutting my present improvement only a small section of the bar is cut away at the'bottom to form the slot 9 for the solder. The bar is therefore much stronger and is less liable to be bent or buckled in use in the drawing frame.
In general, therefore, my improved fallerbar is much more economical to manufacture and repair, and much more efficient in use for the reasons as hereinbefore explained. While I have herein illustrated the improvement as embodied in a certain type of fallerbar and with a preferred construction of the elements thereof, it is to be understood that various modifications may be made in the form and arrangement of the parts of the device without departing from the spirit or scope of the invention. Therefore, without limiting myself in this respect, I claim:
1. An improved fallenbar provided with a series of cylindrical holes, and a series of pins formed with cylindrical shanks inserted in the holes in the .bar and secured fixedly in place therein and having flat-sided blades projecting therefrom in opposite spaced relation.
2. An improved faller-bar having cylindrical holes spaced along its upper edge and a slot on its under side, and pins having fiatsided working portions with cylindrical shanks, the shanks of said pins being inserted in the holes in the bar and anchored in place by solder flowed into the slot thereof.
3. As a new article of manufacture, a pin for faller-bars constructed with a pointed flat-sided portion and acylindrical shank extending therefrom.
4. As a new article of manufacture, a pin for faller-bars constructed with a cylindrical shank and an integral flattened blade projecting longitudinally therefrom.
5. Annnproved method of manufacturing fallers for g1ll-draw1ng frames, consistlng in providing a bar with cylindrical holes spaced alongits top, providing pins having cylindrical shanks and flat-sided blades, setting the pins in the bar by inserting their shanks-in the holes thereof, and finally soldering the pins in place in their holes.
(3. An improved method'of manufacturing into the slot in the bar to anchor the pins in place. I
7. An improved method of manufacturlng fallers for glll-drawing frames, consisting in providing a bar having cylindrical holes spaced along its top, providlng pins with flat-sided blades and cylindrical shanks, inserting the shank of the pins in the holes in the bar, providing a fixture having fiat-sided holes corresponding to the shape of the blades of the pins, placing the fixture along the bar with the blades of the pins inserted through the holes thereof whereby to bring the pins into register with their fiat sides in opposed relation, and finally applying solder or the like to thebar to anchor the pins therein. i
In testimony whereof I afiixmy signature.
