Description
UNITED STATES PATENT OFFICE.
ISAAC BROWN, OF BALTIMORE, MARYLAND.
MODE OF DRIVING SAWS.
Specification forming part of Letters Patent No. 9,855, dated July 19, 1853; Reissued February 8,
To all whom t may concern j Be it known that I, IsAAo BnowN, of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in the Method of Applying the Power of Steam'to Sawmill Gates or Frames; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, making a part of this specification.
The nature of my invention consists in so applying the power of steam to the saw gate or frame, of a saw mill, as that, if the said gate or frame should vibrate laterally, or otherwise run out of line, said defect shall not be communicated to the piston or cylinder, and cut, crampi or otherwise injure them.
To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to'the draw- 1n s.
gIhe fender posts A, may be substantially formed of wood, iron, or parts of each, and I firmly attach thereto the steam cylinders B B, of any of the ordinary constructions. and through said cylinders, in proper stuffing boxes, I pass a piston rod o, furnished with a single piston head, and extending sufficiently far beyond each end of the cylinder, so that one end of each of said rods, may be almost in contact with the underside of the projecting` top piece D, of the saw frame; and the other end of said rods may be also nearly in contact with the brackets E, formed on the outside of each of the side pieces F of said frame. The rods 0, should have just play enough, between the top of the gate and the brackets, to allow for expansion of the metal and prevent cramping or binding; and they may, instead of workbottom piece G of the frame, and work against projections thereon, similar to those in the top piece D, but this would only require longer and heavier piston rods without achieving any desirable object, unless unusual length of vibration or stroke is required. The rods should work close enough between the projections and the brackets, to prevent slamming or wearing, and it may be found advisable to insert a piece of prepared rubber or other spring between the lng against the brackets, extend down tothe4 rods and the projections. The object in leaving the rods unconnected from the gate or frame, is for the purpose of preventing the play of the gate from being communicated to the pistons, and causing them to cut or bind in the packing or cylinder, which would be the case if attached, for then the top of the gate would serve as a cross head, and all the lateral vibra-tions or strainings of the gate would be communicated directly to the piston rods. By my arrangement the pistons will Work true in the cylinders, whether the gate works out of line or not.
On the top piece of the gate, at each end thereof, and connected thereto by wrist pins a, a are the pitmen or connecting rods I-I, I-I, their lower ends being also similarly connected by wrist pins h, to the fly wheels I, I, on the shaft J, and said fly wheels may be counterbalanced to facilitate the vibrations of the gate. The carriage or feed rollers for feeding up the material to be sawed, may be of any of the usual well known forms of construction, and may be operated by the engine in a manner well known to mechanicians.
I have represented in the drawings two cylinders and a Oang of saws. A single cylinder and a sing e saw may be used, in which case the cylinder and piston rod may work within the vertical side pieces of the gate, or near enough to its center to properly balance it, and the saw may be hung to the projecting ends of the top and bottom pieces of the gate. I have also represented the pistons as moving, and the cylinders as being stat-ionary. But the cylinder may be made to move and carry the gate, while the rods may be fixed or immovable, and although not so mechanical, would produce the same result.
The placing of the cylinders between or within lines drawn horizontally from the top and bottom of the gate, enables me to place the whole apparatus upon one floor, which I believe has never been done before, for in all cases of which I have knowledge, Where the direct action of steam is applied to the driving of a saw mill gate, the cylinder has been placed either above or below the gate, which involves the necessity of an extra height to the building, and is objectionable particularly when the mill is in a portable form.
Having thus fully described the nature of my invention What I claim therein as new lateral motion which the gat-e may have,
and desire to secure by Letters Patent, is, Which causes it t0 bind or cut in the cylin- The mode `herein described ofiappiying der, substantially as described. the power of the engine to the Saw gate or ISAAC BROWN. 5 frame, Without being permanently con- Witnesses:
