DANIEL HOWARD HAYWOOD,'9 NEW YORK, Nays PROCESS FOR MANUFACTURING HAIR-PINS.
Specification of Letters Patent.
Patented 6, 1907.
Application filed November 23,1906. Serial No. 344,680.
To all whom 'it-may concern:
Be it known that I, DANIEL Hownm) HAYwooD, a citizen of the, United States of America, and a nesidcnt of'New York city, county, and State, have invented certain new and useful Improvements in a Process for to a process for the manufacture of that kind of hair pin which is composed of a central'metallic core and an outside covering of a material which is plastic'during the course of manufacture. I
. My invention consists broadly in feeding the central cores successively; and with short-intervening spaces between their adjacent ends, through a die, and in simultaneously sq' uirting plastic material through the said die around the said core. The units may be separated either during the process of manufacture or later, by. severing them at points between the adjacent core ends, and the plastic material may be formed or pointed around the core ends during the process of manufacture by momentarily reducing the size of the die opening,
as will be fully setforth in the particular description units may be bent into the proper form to constitute finished hair pins.
In order that my invention may be fully understood, I will now describe in detail a'process in which the said invention is embodied, and will also describe an apparatus in which said process may conveniently be carried out.
The apparatus is illustrated in the accompanying drawings, in which:
' Figure 1 is a view in central longitudinal section I therethrough; Fig. 2' is an enlarged detail view in central longitudinal section through the die and certain contiguous and oo-related parts. Fig. 3 is a detail face view of the means employed for varying the size of the diezepening to form the ends ef the units and to sgzer Itheunitsone from another. Fig. .4 is a view in transyerse section through the feed hopper. Fig. 5 is a detail view in longitudinal section through a stripof the material, showing the same as it. appears when fed ,through the die opening withoutvarying the size of the die opening. In this form the units will be evered after the strip has been completely formed and 7 are detail views respectively in longitud' al and transverse section of the means employed for rolling up and finishing; the units after theyhave come from the igs; 6
I will be delivered in the form of a plurality of units.
.The rollers 17 maybe. conveniently provided with First describing the apparatus: the same, as herein shown, comprises a receiver 10 having a die opening 11 therein, and provided witha screw conveyer 12 by means of which materialmay be forcedi'rith the said receiver and through the die opening 11. The receiver is jacketed as at 1.3, whereby heat may be applied to maintain the material in the receiver'in a plastic conditiom. I
At the rear of the recciver'is a'feed hopper 14 arranged as a magazine for pointed 'wires 15, which are to be employed as themetallic cores of the. hair pins to be manufactured. A feed plunger 16 is provided,
14 to and through the die opening 1.1. Immediately in advance of the die opening 11 is-a pair of rollers 17, whichv are arranged to receive the hairpin units as they pass out from thodie 11, and to continue the food during the return portion of the reciprocating movenient of the plunger 16. The plunger 16 is timed so as to feed the cores 15 forward with intervening spaces between the adjacent ends of the said cores, that is to say, with intervening spaces between the rear end of the advance core and the forward end of the core which follows it. In front of the rollers 17 is a transverse conveyer 18' arranged to receive the units as they are delivered from the rolls 17, and to carry them away to any suitable place.
The preferred material which I employ as a covering to the cores 14, and'which is hence contained in the receiver 10, is celluloid, said celluloid being kept in a plastic condition by means of'the heat conveyed to the receiver through the jacket 13. .The operation of the conveyer 12 simultaneously with the feeding of the cores through the die opening 11 will cause the to form or point the covering material around the core ends, I providenieans for varying the size of the die opening, herein shown'as comprising plates 19, 20"
mounted in slides 21, and having openings 22 of sub stantially the form andcharacter shown in Fig. 3.
Suitable means are provided for-reciprocating the platestoward and away from each other, the effect be-r ing to contract the amount of the dpening'between the parts 22, and finally to close it altogether if desired.
, Plates of this character will therefpre, if properly manipulate d not only form and point the plastic matee pointed ends of the cores, but will also sever the mariner this point, so that the product projecting portions 23 which tend in their operation to correct any inequalities inform and shape which-may have Occurred at the ends of the units, the said por tions operating upon, the plastic material before it is entirely hard. The rollers 17 may themselves be heated if desired. After'the unitshave thus been between a rotating forming roller 24 and a stationary forming member 25, such as is shown in Figs. 6 and 7-. This will insure perfect truth, uniformity and'smoothness of finish. After this operation the units may be suitably bent to form them into the desired shape of hair pins, this operation being. unnecessary offurther description herein, being well understood and formjingno part per se'of the present invention.
'What I claim is:
1. The herein described process which consists infeeding hair pin cores successively and with short intervening spaces between their adjacent ends, through a die, in simultaneously squirting plastic material through the said die around the said cores. and in forming the said material. into a point around the core ends by varying the size of the die opening as the ends-of the cores pass through.
- 2. The herein described process which consists in feeding hair pins successively and with short intervening spaces between their adjacent ends, through a die, and in simultaneously squirting plastic material through the said die around the said cores, in forming the said plastic material over the core ends by varying the size of the die opening as the ends of the cores pass through and in sver-.
ing successive units, and in then rolling the said units transversely between forming members.
3. The herein described process which consists in feeding hair pin cores successively and with short intervening spaces between their adjacent ends, througha heated die, in simultaneously squirting celluloid in a plastic condition through the said die around the said cores,'and in forming the said material into a pointaround the core ends by varying the size of the die opening as the ends of the cores pass through. 1
4. The herein described process which consists in feeding hair pins successively and with short intervening spaces between their adjacent ends, througha heated die; and in simultaneously squirting celluloid in a plastic condition through the said die around the said cores, in forming the said plastic material over the core ends by varyingj the size of the die opening as the ends of the cores pass through and in severing successive units, and inthenroliing the said units transversely between forming members.
