IMPROVEMENT IN REED-SETTING MACHINES.

` The Schedule `:referred to in these Letters Patent and n'akng part of the same I, JOSEPH BROWNING, of the city of Philadelphia, State oi'dennsylvania, have invented certain Improvements in Machines for Setting and Resettin g Reeds, of which the following is a specification.

Natzrreand Objects of the Invention.

Iheiirst part of my invention relates to combining, with the` ordinary mechanism of a reedsetting machine` a self-actingA device for detaching thev splits from old reeds, and delivering the same to the machine for resetting, without handling. A y

The-second part of my invention consists in the adaptation of apart of my improved resetting device for feeding new splits to the setting-machine from a vcontinuous coil ot' prepared wire.

Description of the Accompanying'Drawing. Figure 1, sheet 1, is a side elevation of a machine embodying myinvention.

Figure 2,. sheet 1, is a plan t' the same.

Figure 3,sheet 2, is an elevation showing that part of the machine which is at the left-hand end in fig. 1.

` Figure 4, sheet 2, is -an enil view of the driving machinery, near the right-handend of lig. 1.

Figures 5 and 6, sheet 1, are detachedviews of the parts for separating the splits from old reeds, and carrying them to the new ribs for resetting.

Figures 7 and 8, sheet 2, are detached views illustrative of the manner of entering the splits between the ribs in an inclined position, and of the manner of A' increasing the tension of thelapping by the action of 'the drivers. t

A isthc main driving-shaft of the machine.

-B B are frames secured to the bed-plate O, and carrying the various rock-shafts and vibrating arms actuated by cams D D on shaft A, and giving motion to the combined mechanism of the machine.

The ribs a a placed into themachine to form anew rieled, are held in frames E E at each end of the mac ine.

F F are the drivers, consisting of hollow tubular sleeves, carried in a trame, G. The two pars of ribs a, a pass freely througlrthese drivers, to which a reciprocating movement is impartedl from the grooved cam-D by means of levers b' b', rock-shaft H, and' `links c o.`

ting, is also mainly attachedto frame I, beneath the guide K. Y t i The only preparation required in the old-reed L to tit it for passing through the self-acting resetting mechani'sni of my machine, is the same as that re`, quired forthe ordinary method of removing the slits by hand, and consists in removing one side ot' each rib of the reed by cutting lengthwise through thelapping between the part to be removed and the splits, (see fig. 2.) 'lhe remaining portion of the lapping suiiices to hold the. splits firmly enough to the remainingside of the ribs.

The old reed thus prepared, and having all crooked or defective splits removed, is 'stood upright into the guide-frame K, its undermost split resting upon an entablature, c1. l

' e is a sliding plate, having V-bearings in the entablature d, on which it slides in the manner fully apparent from figs. 1,5 and .6.

The thin forward end of slide e, being on a level withthe' lowest split, carries the latter with it in moving forward, and deposits it in an inclined groove corresponding with the position of the removed split shown in. fig. 6. l n

As the slideeis withdrawn to the position seen in g. 5, the reedL descendsby gravitation, bringing.'

its'next lowest split to rest on (l, to be in turn detached by the next forward motion of e. Each split thus removed `from the old reed and deposited in the rear, is removed in an endwise direction b'ya feeding-1 bar, f, which pushes it forward and places 'it between the ribs of the new reed ready for the final operation of setting by means of thedrivers F F.

The slide c and feeding-bar f receive each their reciprocating motion from a grooved cam, D', on driving-shaft A, in the following manner A double-armed lever, M, on a rock-shaft, g, com mnnicates `the motion given to its lower larm by thecaml D to an upper rock-shaft, h, which, by reasonot the relative length ot' its arm t' to the greater length ofarm M, receves'a much increased throw.

This vibration of shafti-h imparts,l by means of its long outer arm N and'link k, areciprocating movement to a longitudinally-sliding rack, O, which through toothedpinions jj' on an upright shaft, l, again gives a reciprocating movement to a laterally-sliding rack, P, which carries, on a head-block, Q, the above-men tioned feeding bar f.` The amount of the motion thus given to feed-bar f is easily and nicely adjustable. by setting the pin m (which joints link la to armN) to any desired throw within the slot in arm N, -This same arm carries a second adjustable pin, a,which imparts a vibrating movement to a shorter arm, R this arm, having its fulcrum below, vibrates in the ,opposite direction to arm N; `it carries at its upper
