JAMES R. LoeAN, or BELLMORE, INDIANA. Leam Patent No. 66,602, dated July 9, 1867.-

IMPROVEMENT IN SAWIG MACHINES.

TO ALL WHOM IT MAY CQNCERN:

Be it known that I, JAMES R. LOGAN, of Bellmore, in the county of Park, and State of Indiana, have invented a new and improved Sewing Machine and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference 4being had to thc accompanying drawings, forming part of this specification, in which- Figure 1 is a plan or top view of my invention.'

Figure 2, a side sectional viewot' the same taken in the linex x, tig. l.

Figure 3, a transverse vertical section ofthe same taken in the liney y, iig. 1.

Similar letters of reference indicate corresponding parts.

This invention relates to an improvement on a new and improved cross-cutsawingimaohine for which Letters Patent were granted to mebearing date December 19, 1865. The within-described improvement consists in a peculiar construction of the carriage on which the machine is mounted, whereby the frame of the machine may be retained in a horizontal position when placed on uneven or inclined ground. The improvement also consists in a modification of the construction of the standard or support 'to which the saw-bar is attached when sawing felled timber, and further, in the employment or use of a saw-guide, all arranged as hereinafter set forth.

Arepresents a rectangular frame, the rear part of which is supported' by two wheels B B, the axle C of which is ot' double-inclined form, as shown in iig. 3, its upper surface being highest at the centre. On this upper surface of the axle a transverse bar, a, of the frame A rests or bears. The under surface of this bar a is of" double-inclined form, it being thickest at the centre, and the frame A is secured to the axle C by a bolt, b, passing centrally through a and C. D D represent thills or shafts attached to the frame A; and E is a bar which is framed into the rear end of the frame A, extends upward a suitable distance, and is then bent over in n. forward direction, and has its front end'sccured to the front cross-piece c of the frame A, as shown clearly in iig. 2. This bar E may be of wood, and, in consequence of being constructed and applied as shown, is rendered very stiff and rm, and is well calculatedto support the bar FV, which, when the saw is cutting felled timber, works on a pin, d, projecting from the bar E, asshown in figs. 1 and 2. The saw-har G is attached to the end of the bar F in the saine way as described in the original patented machine, and thc har F, 'when standing timber is to bc Sawed down, is placed in a horizontal position on the frame A, and works on a pin,f, at either side thereof, the saw in the latter case being fed to its work by a spring in a block,- H. This arrangement is precisely the same as' thc original, with the exception that a weight, g, may be connected with or'used as an auxiliary to the spring. The axle C has a verticalpin, h, attached to it near each end, and 'these pins pass up through oblong slats z' in `the cross-bar a, and servel as guides for the frame of the machine. This manner of it'ting the frame A on the axle-C is a` great improvement, the machine frequent-ly is required to stand upon inclined ground, and, when this is the case, themachine may be kept in a horizontal position. I is a guide attached to o1` fitted in the front cross-piece c of the frame A,Isz1id guide b'eing composed of a bar slotted vertically for the saw-bar G to work through. Thebar F is operated by a pitman, J, from a crank-shaft, K, as hitherto.

Having thus described my invention, I claim as new, and desire to secure by 'Letters Patent- Allowing the frame of the machine to conform to any inclination of the log, by means ofthe slotted transverseV bar aresting on axle C, providedwith'pins h, constructed as described, and operating substantially in the manner and for the purpose specified.

JAMES R. LOGAN.
