JOHN H. BRAOKETT, OF DOVER, HAMPSHIRE.

FEEDING DEVICE FOR CARDlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 227,672, dated May 18, 1880.

Application filed August 22, 1879.

To all whom it may concern Be it known that I, JOHN H. BRAGKETT, of Dover, in the county of Strafl'ord, in the State of New Hampshire, have invented an ImprovementinFeedingDevicesfor Garding-Machines, of which the following is a specification.

This invention relates to an improvement in mechanism for feeding finishing-cards.

In the drawings, Figure 1 represents aside elevation of my improvement; Fig. 2, a crosssection representing a detail in construction. Fig. 3 represents a modification in construction. Fig. 4 represents a view in which two positions of my device are shown. The one in full outline represents it in the position commonly occupied by the ordinary card-feeding device, and the one in dotted outline shows its movement in one direction to coincide with the movement of the feeding-rolls of the carding-machine. Fig. 5 represents a perspective view of my feeding mechanism and a portion of the A i erl Ulissold feeding mechanism for carding-machines, showing the manner in which the sliver is fed .to the feedingrolls of the carding-machine, and the manner by which the feeding-rolls of my improvement are provided with a horizontal movement coincident with that of the feeding-rolls of the said cardingmachine.

My improvement is particularly adapted for use in connection with the card-feeding mechanism described in patent to J ames Apperly and W. Glissold, No. 18,888, of 1857.

Although I may use any suitable supports for the drawing or sliver, I prefer to employ the feeding-rolls A A constantly revolved by the belt a, which passes over the pulleys b b upon the roll-carrying shafts b 11 The shaft b is provided with a suitable bearing in the under portion of the collar 0, and the collar is adjustable upon the supporting-arm c, and can be fastened in any desired position by the set-screw 0 The shaft b has a bearing in a suitable projection on the collar 0 on the vertical standard d. It is secured in place by the collars d and set-screws 01 The collar 0 also supports the horizontal arm 0, which is attached to it either by a sleeve and setscrew, as shown in Figs. 1 and 2, or. by a hinge or loose connections, as. shown in Fig. 3.

The stay-rod 0 assists in the support of the horizontal rod 0, and limits to a certain extent its movement.

The standard cl may be suspended from any suitably bracket or support, or may be fastened to the floor or to a table.

When it is desirable the arm or rod 0 may have a vertical yielding movement in addition to a horizontal swinging movement, and a ball-joint or other hinge may be employed for fastening it to the collar 0 in order thatit may have a vertical swinging movement.

4 To limit the extent-of this movement and to support the horizontal rod, one or more springs, f, may be employed in lieu of the stay-rod e,- or the rod may be floatedby two springs, one above and one below it, as shown in Fig. 3.

The rolls are driven by the pulley g ou-the shaft 1) and the belt g, which connects with a pulley on any rotating part of the carding mechanism. The rod 0 is provided with a horizontal swinging movement coincident with that of the feeding-roll h on the carding-machine by any suitable mechanism, but preferably by means of the strap in, which connects the head h, carrying the feeding-rolls, or any reciprocating part of the carding-machine, with theend of the rod 0.

In operation the sliver or drawingis passed over the rolls A A to the feeding-rolls h of the carding-machine, and as the feeding-rolls reciprocate the sliver or. drawing is fed by the feeding-rolls, which are brought in a line with the feeding-rolls in the carding-machine as they are moved therewith, and the sliver or drawing therefore passes without friction and with very little tension to the receivingrolls h.

My improvement may be so supported that the rolls shall be upon the same level with the receiving-rolls of the carding-machine, or it may be on asomewhat higher level, in which case, however, there will be no difference in its action, as the sliver or drawing, in passing over'the rolls down to the feedingrolls of the carding-machine, is not drawn against an angle in such a manner as to dis-' turb the tension.

Having thus fully described my invention,

I claim and desire to secure by Letters Patent forth, for supporting said arm in a horizontal of the United Statesposition, all arranged to operate substantially 10 In a device for transferring sliver to the as and for the purposes described.
