IMPROVEMENT IN SAWlNG MACHINES.
Specification forming part of Letters Patent No. 139,965, dated June 17, 1873; application filed April 12, 1873.
' connection.
Similar letters of reference indicate corresponding parts.
This invention relates to an improvement in the mechanism for sliding the bearings of the saw-mandrel. in a ripping and cross-cutting machine; and consists in the connection of the sliding carriage andits belting with a powerful foot-lever and friction-rollers, by which the saw can be moved and operated in both directions, and adjusted rapidly for the different purposes to which the machine is applicable.
In the drawing, A represents the frame of the machine of the usual shape; B, the saw titted suitably into the sliding-carriage O, which moves lengthwise ingnides d d. D is the belt which passes over a roller, a, of the driving-shaft b,- then over a roller, a, of the sa'w'mandrel N,- then over roller a of the .sliding carriage O and roller a of shaft 12 of frame A, rotatingthe saw B, and adapting itself to the rectilinear motion of the carriage C. E and E are two belts stretched longitudinally between downward-projectin g pieces 9 of carriage- They are incontact with frictionrollers e and 0, respectively, whose shafts turn in journals of frame A. Between these rollers e e is hung a double roller F, the shaft b of which is connected with lever G, and constantly rotated by belt h, or other connection with the driving-shaft b. The front end of lever Gris connected to a treadle I, which is operated by the attendant by pressing roller F either against belt E and the upper friction-roller e, or against belt E and the lower friction-roller 6. Whenever roller F is brought up against belt E, the friction exerted upon it by the rollers F and e compels the saw to move forward, but its motion is reversed when roller F is brought down on belt E and roller 6. In place of belts E and E, equivalent gearing may be employed. K is the rule used in cross-cutting. It is hinged to the side of frame A, and may be folded up against it when the machine is used for rip ping. L is a cap also hinged to the frame at the front end thereof to be folded over toward the saw to protect the attendant and serve, in connection with rule K, as a rest in cross-cutting; it is folded down out of the way when the machine is used for ripping.
The operations of ripping and cross-cutting may therefore be accomplished with rapidity and ease,'resulting in a saving of time and labor.
Having thus described my invention, I claim as new, and desire to secure by Letters Patent- 1. The foot-lever G having double roller F, combined with friction-rollers e e to impart forward and reverse motion to carriage G, as set forth.
2. The saw-carriage 0 having projecting pieces 9 for stretching belts E E, with rollers a and a of the mandrel 11 for adjustment of driving-belt D, as described.
3. The hinged guide K and cap L arranged, as shown and described, to operate as specified.
