IMPROVE!) SCREW-FEEDING- APPARATUS.'
The Schedule referred to in theae yIllunstrl Patent and. making part of the saine.
To l'l whom it may concern:
lBe it -knowntbat I, ELIJAH S. PIERCE, of AHartv ford, i-n the county of Hartford, and State of Connecticut, have invented a new and useful Improvement in Apparatus for Conveying Screw-Blanks and I declare the following to be a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference thereon, forming a part of this specification.
-Figure 1 is a perspective view of my improvement, showing also a grasping-device,v which is necessary to show the working of my invention.
Figure 2 is a perspective view of my improvement, separated from the additional device shown in fig. 1.
Figure 3 is an end elevation of my improvement. Like letters indicate like parts in all the figures.
My improvement consists of a new device for presenting wood-screw blanks to a chuck, or other grasping-device, to be heldby such chuck or grasping-de.- vice until being pointed or otherwise operatedupon.
The chuck forms no art of m invention as claimed herein; but a chuck is shown in iig. 1, and described herein, for the purpose of showing the full operation of my device.
The letter a designates a metal conductor, in which the screw-blanks are placed by some proper' device.
From its shape, the tendency of these blanks is to slide, one after another, down toward the position of the blank b, shown in iigs. 2.4 and The blanks arev kept from falling out oi' the conductor, while sliding down, bythe metal shield a.
The letter c designates a sliding bar, whose lower end is cnt out squarely, as best seen in 3..
The spring d tendsl to pull itin the direction shown by the arrow, so that when it is not affected by any other iniiuence, the cut-away portion ofthe sliding bar will forma bottom or stop for tbe blanks as they slide down the conductor. Y y
At such time the lowest blank in the conductor will rest upon the part d of the sliding bar, and the shout der d2 will be against the blank, upon one side of it.
The wire springs e e hold the blank from escaping upon the opposite side from di.
Now, a blank being down in the position just described, just at the vproper moment thel sliding bar is pulled down by'the bar f, operated by the cam g, upon the shaft h, and the cut-away portion moves one blank down into the position shown in iig. 3, the next blank in the conductor resting meanwhile upon the top of the shoulder (Z2.
At this point a-snlall plunger, fi, moved by `the arm j, pivoted at k', and operatedby the cam Z, upon the shaft h, moves .forward in the direction shown by the arrow, and pushes the head of' the blank out beyond the shield a', so that the chuck m., operated by suitable devices, grasps the head ot' the blank firmly.
'The chuck, having grasped the blank firmly, carries it downward in an oblique direction, pressing it out by l the ends of the springs c,h when the operationof feeding a single blank is finished.
Then the chuck, still holding the blank, arrives at the position shown in iig. 1, the blank is ready for pointing, or for any otheroperation.
But all this forms nopalt of the invention claimed herein, and is only described andA shown for conven,
ie'nce sake, in. showing tbe operatiqm of my improvement.
The part claimed as new herein is exclusive ofthe chuck or grasping-device.- But some grasping-device is necessary to be used in connection with my invention, for the purpose of grasping the blank and carrying it downward and out .from theI embrace ot' the springs c c.
I have so far described only bow one bla-nk is fed. It will be readily understood that all the others are .fed in precisely the same manner. v
After the sliding bar c has carried one blank down,
it is carriedback to its place by the spring (l, ready for another operation, as is also .the plungeri, and with each revolution ofthe shaft h., a blank is fed into the chuck and disposed of by the same.
I ,claim as my invention 1. The arrangement of the springs e c, sliding bar c, and conductor (l, constructed and operated as described, for the purposes set forth.
2. lbe combination of the conductor (l), shield a', sliding bar c, with its springs (l, and the springs c c, Y
the Whole constructed, arranged, and operating as described, fois the purposes described.
3. The plunger i, moved as described, in combination with the conductora, both parts being constructed as described, for the purpose described.
4. The combination of all the parts mentioned lnthe preceding claims, the whole being constructed and 4operating as described, for tbe purpose described.
Dated AJune 18,1869.
