EDWIN II. WITHERELL, :Born or MACHINE FOR MAKING CROCI-IET-NEEDIJES.

To all whom t may concern: i .4 j f Y Be it known that I, ALBERT F. Voiron, a citizen of the United States of America, rel siding at Grand Rapids,jin the county of Kent and State of Michigan, have invented certain new and useful Improvements in Machines for Making Crochet-Needles; and I do hereby, decla-re the vfollowing to be a full, clear, and exact description of the invention, such as will'enable others skilled in the art towhich it appertains to make and use the same. j l

This invention relatesto a machine for making .crochet needles. 'j It is the object and purpose of the inventiontofprovide a mechanism in which arod or bar out' metal may be placed, the machine operating to turn one end of the bar around a suitable die and shape it into a hook such as is necessary to complete a crochet needle. A further object of the invention consists in the provision ot'. a simple and economically constructed machine for attaining the result stated and one in which the working parts of the machine that act upon the bar or rod` are compelled to pass through certain movements positively in the bendingand formingof the end of the bar into a hook.` Other objects and purposes together with novel details of structure Vforattaining the same will appear as understanding is had of' the invention, reference being had to the accompanying A drawings which illustrate a .preferred embodiment of the same. i I

such viewsbeing enlarged to. better show the construction.' n j linke reference characters referto like parts throughout the several views of the Inl he constructionillustrated, elongated metal strap lis provided which `may be attached to a table or other support Projecting upwardly'from' one end of" this 'strap is a block through which a shaft 4 passes. It is contemplated in the use of Specication of Letters Patent. Pgijgntd Siglato jjj, 19170 Application led June 12, 1916. `Serial No. 103,283.

this invention that a plurality of machines shall be placed upon and attached to table 2, the drive shaft 4, which may be driven in any suitable manner, passing through all of the blocks 3. A pinion 5 secured to the shaft'near the block meshes with a `gear 6 the diameter of which, preferably, is three timesthat of the driving pinion `5, though any other suitable size of gear may be used. A stud 7 is secured to and 'projects from one face of the gear 6. i j

At 'theopposite end of memberl a support is Secured comprised ol a horizontal baseS having uprights 9 and 10 at the ends which areeach `connected by a table 11 divided at one end to make. spaced apart legs 12 between which an irregular shaped member 13 is adapted to move. Member 13 is pivotally connected adjacent lits lower end to the forward end of a bar 14 suspended b v means of links 15 and 16 from the table 11. A coil spring 17 attached to the bar 14 and to the upright 10 has a` normal tendency to pull this'bar toward the upright and retract the member 13 to itsloweimost position, as that shown in Figs. 4 and 5. A curved slot 18is" cut in the member 13,` a pin 19 supported between the legs 12 passing through the slot and liinitingthe movement ot bar 14.

A pin20 which is used to pivotally conneet the lower ends of links 16 and the bar 14 projects a distance beyond the links and enters a slot 21 formed in` one end of an operating bar 23, the pin being provided with a head 22 which serves to keep the bar from disengagement therefrom. The operating bar extends alongside gear 6 and has a portion cut awayon its under side adjacent its opposite end as indicated at 24 and is also formed with a concave notch 25 in which the stud 7 may seat. When stud 7 `is at its uppermost position on the gear the Projecting upwardly from the table 11 is.

a plate 26 serving as a support for a die 27 pivotally mounted on the face of the plate and having an inclined upper surface so that the die at its free end comes to a point..

A cam 28 lies directlyA above the inclined surface of the die being mounted on a pin,

which extendsthrough the plate 2'6, the pin at the opposite side of the plate having a lever 29 fixed thereto. The lever'29. at a point somewhat above at its lower end has a concave recess 30 cut therein which is adapted to be engaged by a pin31fprojecting laterally from bar 23. Alsothe irregular shaped member 13 has a right angular notch 32 cut therein which'in the normal position of thejvarious parts of the mech-k anism lies directly in front of the end vof die 27. Below the notch 32 the irregular shaped member has a surface 32a which coacts with the die in completing the hook as will be later described. v

, A stop 33 is a'djustablj,7 secured to the end of table 11 directly above upright 10 and' is right angular in cross section one leg33L parallelingvtablell while the'other crosses it. The adjustment is effected by means of a screw 34 passing through the slot 35 in stop 33 and entering the table 11.

A rod of metal from which the needle is to be formed is laid upon the table 11 one end contacting with the stop 33 While the other enters the notch 32 in member13 passing underneath the die 27. As gear 6 turns the first movement bends the end of the bar around the end ofthe die it being *thereafter engaged by the. surface 32a of clined vside of die 27 and holding the metal rod firmly in place during the operation of the mechanism.. After the hook is completed thek further movement ofthe gear `next operation. If at anytime it is desired that the hook Vforming mechanism shall be at restfor. a time this canbe easily attained by positioningpin 31 in'a notch 36i`cut in the lever 29 below the recess 30 heretofore described, this serving to liftg theV end vof operating bar 23 Vout of engagement withV stud 7 In this manner va plurality of machines may be drivenV by one shaft 4 yet anyV one of the machines be' disconnected fromthe driving mechanism and permitted to be at rest while the rest of the machines are in operation. a Y 4 The operator ofthe machines inserts the rods one after another in the machine with each revolution of the gea-r3. i This gear is driven at a comparatively low speed as the drive shaft 4 makes three completerevolie tions for each revolution of the gear and plentyof time is giveni'for the removal 'of the crochet needles and insertion ofthe rods from which the needles are made'.` Whena hook has been formed cna needle bar it is necessary thereafter merelyfto slightly grind the hook thus formed to complete theV iinished product. f I clai1n:-
