Specircation of Letters Patent No. 681, dated April '7, 1838; AnteiatedOctober` 7, 1837'. i f i To all whom t may concern:

A Be it lmown that I, REUBEN DANiELs, of Woodstock, in the county of Windsor and State of Vermont, have invented a new and useful Improvement in the Construct-ion of Crosscut EclipseV Shear-ing Machines for Shearing Woolen and other Cloths from List to List, and that the following is a full and eXact description of the construction and operation of said machine as improved by me, v iz:

Let there be constructed on a suitable platform or floor a railway of wood or other material having on the top a metallic wire smoothly finished two o-r more inches above the platform or Hoor; the length of the rails and their distance asunder being adjusted to the width of the cloth to be sheared, and to the length of the shear. The design and use of this railway is to receive and guide the cloth carriage under `the shear in the process of shearing, and also the form and attachment for the cast iron spectacle frame, so called, from its resemblance to spectacle bows. This attachment must be on the outer side of the rails, so 'as topermit the cloth carriage to pass on the rails within the cast iron spectacle frame. The cast iron spectacle frame is a massy casting consist-` ing of one entire piece, the object of which is not only to form an unyielding stationaryV support tothe rest underneath the shear frame but also to give attachment to the iron shear frame in which the revolver runs, and to which the ledger blade is attached. This rest is attached to the spectacle frame by means of set screws in such manner that either end of the rest may be raised or depressed or moved backward or forward so as to be exactly adjusted to the revolving and ledger blades while shearing. The upright spectacle frame gives attachment to all the stationary parts of the machine above the rails. It isconstructed with two upright posts of the height of the cloth carriage. These posts are connected by two circular parts adapted to receive the cloth rolls, having the cloth wound around them. These clothrolls or beams are a portion of the cloth carriage and as long as the width` of the cloth to be sheared. The form of the spectacle frame is shown in drawings Figure 5 and marked N, N. Immediately above the two circular parts is placed the `cloth rest, which is fastened to them bymeans of set screws already described.` "The top of this rest is to be brought to a degree of sharpness resembling No. 18 wire so as to present but a very small portion `of the cloth to the action of the shear in each successive portion of timegand Ayet not so ,sharpV asto endanger the rendingof the cloth.- A The ends of the rest are to be smoothly rounded to permit the cloth to pass without damage` The shear frame isV placed over the restin such position that `the edge of the ledgerV blade falls immediately 'in contact` of the Y rear of the upper edge -of the rest, while the center of the revolving blade lies imme! diately over the wire edge of the rest.

l/Vitliin a small distance of this edge twopermit the nap to rise above the thread to meet the action ofthe shear. These ledges or projections are shown, Fig. 3 and marked L, L. The shear frame is of one solid casting and gives attachment to the revolving and ledger blades, the oiler stand and oiler, the gage screws, and dial, and dial dog with the ledges above described, and marked L, L. The ledger blade is a separate piece, and is attached to the shear frame at each end, and iii the center by set screws, so that it can be raised or depressed at pleasure. The object of the set screws in the center ofthe ledger blade is to attach the ledger blade to a strong and unyielding portion of the shear of the shear frame is marked in the draw` ings by Q and the set screws are shown by lip D. A stand is attached to the spectacle frame to support the bearings of the shear` frame which is :so constructed as either to lie down close to the cloth while shearing or to be raised up when the shear has reached the list andthe cloth frame requires to be drawn back .preparatory to` shearing another portion of the cloth. This stand is marked B, in drawing Fig. 2. The strong unyielding portion of Athe shear frame is shown iiidrawing Fig.` 1, and marked Q as above described. Two scroll stands are attached to the spectacle frame andare shown' inthe drawing Fig.l 3 and marked S, S. Into these scroll standsare introduced the bearings of the balance shaft small'friction roller, end of shaft in contact With cam. K dog shaft shown in Fig. 3. L pinion Wheel playing into gear.

In the specification thus presented, it is not designed to specify every minute portion of the machine: and those portions not specified are common to this and other machines of a similar kind in use.V

All I claim as my invention i y Y The above combination and arrangement of any two or more of the following particulars of the above described cross out eclipse shearing machine, when combined with the cloth carriage; first, I claim the cast iron receptacle frame; secondly, the cloth rest With Wire edge; thirdly, the dial plate set screwsl to regulate the length of nap; fourthly, the cam to lift pinion Wheel out of rack, and fifthly, the ledge to depress the cloth in front of the shear. But I do not claim as my invention any one of the above described parts, or a combination of them, independently of their combination with the cloth carriage, nor do claim the` cloth carriage as my invention.
