FEED MECHANISM.

To all whom it may concern Be it known that I, Mioimnt Bnoonn, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented new and useful Improvements in Feed Mechanisms, of which the following is a specification.

My present invention relates to feed mechanisms, particularly to such as are used with woodworking machines; and its object, generally, is to provide mechanism of that character, which shall be simple and economical in construction and easy and effective in operation; and more particularly, which shall have removable, replaceable and interchangeable work -engaging parts, in order that, becoming worn, they may be removed and replaced with others, and also in order that, becoming unequally worn interrelatively, they may be interchanged to secure a desired uniformity of wear throughout; and also to provide a mechanism of that character, in which said parts shall be severally relieved from all working stress during a portion of the mechanisms operation; and also to provide mechanism of that character which shall be variously improved as hereinafter appearing. These objects are attained by, and my invention finds a preferable embodiment in, the structure hereinafter described, and illustrated by the accompanying drawings, in which:

Figure 1 is a front elevation of my feed roll with portions of connected parts and shown partly in vertical longitudinal section: Fig. 2 is an enlarged detail view of a portion of the same: Fig. 3 is a view in perspective of one of the work -engaging members annular carriers: Fig. 4 is a similar view of one of such work-engaging members; Fig. 5 is a like View of a retaining clip for such members; Fig. 6 is a longitudinal sectional view of one of said carriers taken on planes in which the sockets for said members do not lie, and illustrating the annular groove in each face of the several carriers; and Fig. 7 is a fragmentary similar view of such a carrier, illustrating variant means for retaining said members in their sockets.

A feed shaft 1, suitably journaled at 2, 2 and driven as by its gear 3, is provided with a plurality of encircling removable annular carriers 4, held side by side thereon by suit- Specification of Letters Patent.

able means, as the collar 5 toward one end of the shaft and the nut 6 threaded thereon toward its other end. .The material oper ated on, or the work,as a wooden board 7,-is fed by my feed roll, between it and any suitable cooperating member, as the work-sustaining roll 8.

Each carrier 4 is provided with radiallyextending worlcengaging members 9, preferably rcsilient,as rubber-and adapted to alone engage my feed rolls side of the work in the feed operation. These members are rcmovably inserted into sockets 10 in the sides or faces of the carriers, such sockets having overhanging outer edges, as shown, to securely hold such members in position.

Annular grooves 11, formed in the sides or faces of the carriers and opening from the bottom of the sockets, permit expansion of the said resilient members thereinto when operatively engaging the work. The sockets on one side of each carrier are alternately disposed to those on the other side as shown, in order that the carriers may not be unduly weakened by the sockets and yet that the carriers may afford a circumferentially unbroken surface engaging the work. The shaft 1 has a key 12 and the carriers have corresponding key ways 13 so that the carriers will be rotated with the shaft, and yet may be longitudinally removed from it when desired: when so removed, the wire clips let whose ends are adapted to be inserted into orifices 15 in the carriers, or screws 16, or any other suitable means may be provided to hold the members 9 in their sockets.

It will be seen that the several members 9 are entirely relieved from all working stress except when actually engaging the work, which in the construction shown is only about one eighth of the time,--whereby the resiliency of the rubber, etc, of which they are formed, is prolonged: also, it will be seen that when worn, these members may be removed and replaced with others: and also, that when such members borne by certain carriers (as those near the middle of the shaft) become worn more than those borne by other carriers (as those toward the ends of the shaft), the carriers may be removed longitudinally from the shaft, and replaced thereon in interchanged relation, whereby a uniform wearing of said members is attained.

Not confining myself to details 01 construction shown or described, I claim:

1. A feed roll comprising a rotatable driving shaft, and a plurality of carriers concentric and separably connected therewith, each having a socket opening at the carriers side and having overhanging walls, and a workengaging member carried by the carrier in the socket and extending radially beyond the periphery of the carrier.

2. A feed roll comprising a rotatable driving shaft, and a plurality of carriers concentrio and separably connected therewith, each having sockets on each side, the sockets on one side being alternately disposed to those on the other side, and having work-engaging members carried by the carriers in the sockets and extending radially beyond the periphery of the carrier.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
