Letters Patent No. 113,182, dated March 28, 1871.
IMPROVEMENT'IN MACHINES FOR SCOURING NEEDLES.'
l The'shedne referred to in these Letters Patent and making pax-t of.' the same.
To all whom it may con-cern 4 Be it known that I, FRANCIS W, Mknnnjr'r, of .New Haven, in the county of NewHave'n and State of Connecticut, have invented a new Improvement in Machine for Securing Needles and I do hereby declare the following, when taken in connection with the accompanying drawingand the letters of reference marked thereon, to be a full, clear, and exact description'of thesame, and whichlsaid drawingconstitutes part of this specification andrepresents in Figure 1 a top view;v
Figures 2 and 3, longitudinal sections, showing the movement of the plates and in Figure 4, a side View, showing'the'manuer of reciprocating'the plates.
This inventionrelatesfto an improvement in device for performing the operation upon needles commonly called scouring. This lis done by taking the mass of needles 4after they have been tempered and making` the platen causing the packs to roll back and forth to produce the vrequired action. The weight of the platen is adj usted to give the required pressure,- and also requires adjustment for different-sized packs.
The object of this invention is` to simplify this operation by avoiding the aforesaid adjustment; and
The' invention consists in thearrangement of a pair of vertically-reciprocating plates, one or both of' which are slightly inclined, so as to make the space between the two plates narrower at the bottom than the top, then dropping the pack prepared .in the usual manner into the space between the plates, where it finds its own proper position in consequence of the inclination before described, the reciprocating ofthe plates caus- `ing the-necessary action upon the pack.
a is one of the plates, and d the other plate, the two together forming a pair, and arranged in suitable guides A in a Vertical position, but inclined to each other so that the space between the plates is nar- ,rower at the bottom than at the top, as seen in figs.' 2 and 3. This may be rdone by inciining" both plates ormaking one perpendicular and vthe other inclined. I prefer, however, that both be inclined.A
To each of these plates a reciprocating movement is given, so that they rise and fall,'as from the position in fig. 2 to that iu iig. 3, and vice tersa. I arrange a succession of pairs of these plates, as may be desired, here represented as two.
Between these plates the packs B, prepared in the usual manner, are placed, their diameter fixing their position between the plates. If' of smaller diameter,
they simply drop further down into the space between' the '.plates, and if larger, rest higher' up. Thus the pack is self-adjusting ast'o size. The plates, reciproeating as before described, maintain a constant rota# tion ofthe pack back and forth, the pack maintaining the same relative position, except, as by the constant rolling its diameter slightly diminishes, it will work down between the'plates, andthe inclination of theplates, combined with the weight of the pack, gives the desired pressure, which remains constant; and thus the device is practically self-adjusting, both as to the size ofthe pack and the pressure thereon.
The best means known to me for thus reciprocat ing the plates is the arrangement of a crank-wheel, G, upon both ends'of a shaft, D, the crank-ptn c working inthe slot of one arm of a lever, E, the other arm attached to a stud, f, on. the rst plate ;Y thena similar lever,- F, one arm of which is fixed to the stud f of the irst plate, and to a similar' stud, f, of the next plate,and this to the succeeding plates by other levers, G H, asseen in g. 4. Thus, as the crankwheel revolves, the levers are vibrated, 4as denoted by the broken 'lines in fig. 4, alternately raising and lowering the plates to give the reciprocating movement required and before described.
I claim as my invention- A device for scouring needles, consisting of a pair of plates, a d, one-or both of which are inclined so as to make the space between the two plates narrower vat the bottom than at the top, in combination with mechanism for 'imparting a reciprocating movement to both of said plates, substantially as set forth.
FRANCIS W1 MALLETT.
