Definitions
- Figure l is a side view of my improved device.
- Fig. 2 is a front view ofthe same.
- Fig. 3 is a horizontal section of the same, taken through the line m ai, Fig. 1.
- Fig. 4 is a detail section of one of the friction-wheels.
- the object of this invention is to furnish an improved feed and gig mechanism for the carriages of circular-saw mills, which shall be simple in construction and convenient and effective in use, allowing the change of motion to be made quickly and easily.
- the invention consists inV the various combination of the two levers, the two arms, the connecting-rods, the U-bar, sliding ⁇ bearings, friction-wheels, and shaft, all as more fully hereinafter set forth.
- A represents the frame of the machine.
- B represents the drivin g-shaft, which revolves in bearings attached to the frame A or to other similar supports.
- a pulley, C around Whichpasses a belt, D, which also passes around a pulley, E, attached to the feed friction-shaft F.
- the feed friction-shaft F will be driven from the saw-arbor (which is not shown in the drawings) and the saw-arbor will be driven from the drivin g-shaft B.
- the shaft F revolves in a bearin g, f', attached to the frame Aor to abracket or arm attached to the same frame, and in a bearing, f2, attached to the inner end of the friction-lever Gr.
- a small frictionwheel, H which, by the movement of the lever Gr, is thrown into and out of gear with the large friction-wheel I, attached to the feedshaft J.
- the shaft J revolves in bearings attached to the frame A, and to it is attached the small gear-'wheel K, by which the carriage is moved'forward and back.
- a pulley, L around which passes a belt, M.
- the belt M also passes around a pulley, N, attached to the gig-shaft O, which revolves in bearings attached to the frame A, and to itis attached a large friction-wheel, P, placed directly below and at a little distance from the frictionwheel I.
- the friction-lever G is pivotcd to a standard, Q, attached to the frame A, and to its outer end is pivoted the upper end ot' a short connecting-rod, R, the lower end ot' which is pivoted to the outer end of an arm, S,for1ned upon or rigidly attached to .
- the rock-shaft T which works in bearings attached to the frame A, and to it is rigidly attached, or upon it is formed, the feed-lever a, by means of which it is operated.
- an arm, V to the end of which is pivoted the end of a short connecting-rod, W.
- the other end of the connecting-rod W' is' pivoted to the upper end of the gig-lever X, the lower end ot' which is pivoted to a support attached to the frame A.
- a connectingbar, Y which is made in two parts connected by a nut, y', having a right screw-thread cut in one end and a left screwthread cut in its other end, so that the said rod may be shortened to take up the wear by turning the said nut.
- the inner end of the connecting-rod Y is attached to the center of a U-bar, Z, the ends of which are attached to twopbearings, A.
- the bearings A slide in rabbeted bars of the frame A, and are connected at their rear ends by a cross-bar, B.
- the two friction-wheels'H C are so connected that either may be thrown into gear and the other out of gear by a single slight movement of the feed-lever U, thus effecting a great saving of time and allowing the machine to do much more Work than would otherwise be possible.
- the friction-wheels H C are formed of alternate layers of paper and rubber, as shown in Figs. 2, 3, and 4.
- rlhe rubber maybe used in the form of sheets secured between sheets of the paper; or it'may IOO Iol
