UNITED STATES PATENT OFFICEe IGNAT KRENEK, OF FAYETTEVILLE, TEXAS.

SAWINGMACHINE.

SPECIFICATION forming part of Letters Patent No. 633,599, dated September 26, 1899.

Application filed October 17, 1898. Serial No. 693,791. (No model.)

To all whom t may concern:

Be it known that I, IGNATZ KRENEK, a citizen of the United States, residing at Fayetteville, in the county of Fayette and State of Texas, have invented a new and useful Sawing-Machine, of which the followingis a specification.

My invention relates to improvements in sawing-machines; and one of its objects is to provide an improved construction by which the energy developed by a windmill may be utilized for the operation of the saw.

A further purpose is to provide means adapted to be used in connection with the tower and the reciprocating rod of any ordinary windmill, so as to operatively connect the saw to the rod, and such means are also arranged to amplify the length of the stroke imparted by the reciprocating rod to the saw in order to increase the efciency of the latter.'

A further purpose of the invention is to provide means for feeding the log to the saw as the work of cutting such log progresses, such feed mechanism operating by gravity and independently of the means that actuates the saw.

IVith these ends in View the invention consists in the novel combination of elements and in the construction and arrangement of parts, which will be hereinafter fully described and claimed.

To enable others to understand the invention, I have illustrated the preferred embodiment thereof in the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a perspective view of a portion of a Wind mill with mysawing mechanism connected operatively with the reciprocating rod. Fig. 2 is a sectional plan view, the plane of section being taken through the tower above the driving-lever. Fig. 3 is a vertical longitudinal section through the sawingl mechanism on the plane indicated by the dotted line m 'm of Fig. Fig. EL is a vertical transverse section on the plane indicated by the dotted line o o of Fig. 3.

Like numerals of reference denote like and corresponding parts in each of the several iigures of the drawings.

A portion of the tower of an ordinary Windmill is designated by the numeral `10 in Figs.

1 and 2 of the drawings. The reciprocating mill-rod 1l is operated in the usual way by a crank-shaft or by the wrist-pin on a crankdisk of an ordinary windmill; but as my improvements may be used in connection with the tower and the rod of any windmill I have not deemed it necessary to more particularly describe the mill.

To adapt my improvements for use in connection with the windmill, I employ a horizontal framework 12, which is designed to be fastened rigidly to the tower 10. This framework may be of any suitable construction, and in the example illustrated by the drawings it is shown as consisting of a horizontal bar attached firmly by bolts or clamps to the legs of the tower. This framework supports a short vertical fulcrum-post 13, which is made fast tosuch frame by clamps or bolts 14:. As the means foroperatively connecting the reciprocating rod 11 of the mill to the reciprocating saw-frame of the sawing mechanisln I have provided the horizontally-disposed driving-lever 15, which extends across the tower 10, so as to have one end thereof f ulcrumed on the post 13 and its other end properly connected with the saw-frame. This `driving-lever is fulcrumed or loosely connected at 16 to the fixed or vertical post 13, and said lever laps or extends across the reciprocating rod 11, so as to be pivotally attached thereto by the pivotal bolt 17. The reciprocating rod 11 is connected with the driving-lever at a point intermediate of its length to vibrate said lever in a vertical plane when the rod itself is reciprocated by the working elements of the mill, and this pivotal connection between the lever and the reciprocating rod is effected at a point nearer one end of the lever than the other end, thus providing a short arm and a long arm. As shown by the drawings, the short lever-arm is fulcrumed to the post 13, while the long lever-arm is adapted fol` connection with the reciprocating saw-frame, whereby the operation of the lever increases the stroke which is imparted by the pump-rod and lever to the reciprocating saw-frame. The driving-lever is maintained in the proper lateral relation to the pump-rod by which it is actuated by a keeper 18, the ends of which are firmly fastened to the pump-rod, and said keeper re- IOO . the saw.

ceives one end of the pivotal bolt 17 to assist in supporting the latter.

The sawing mechanism is situated at one side of the wind mill-tower, and this saw mechanism embraces a vertical guide-frame 19 and a horizontal table-frame 20, which are joined or united rigidly together in asubstantial way,'said framework of the sawmill occupying a position contiguous to the mill tower for the long arm of the driving-lever to overhang the vertical guideframe 19. The vertical guide-frame 10 is provided -with a raceway 21, which extends above and below the horizontal table-frame, and in this raceway is slidably fitted the vertically-reciprocating saw-frame 22. A vertical saw 23 is arranged lengthwise in the saw-frame and is secured centrally thereto, so as to reciprocate or travel with said frame. The saw-frame and the driving-lever are connected operatively by a pitman 24, which passes loosely through a vertical aperture in the head-rail of the guide-frame 19, and the lower end of this pitman is pivoted at 2G tothe saw-frame. The upper end of the pitman is forked or Vbifurcated at 27 to embrace the long arm of the driving-lever, and a pivotal bolt 2S is einployed to connect the forked pitman to the long arm of said driving-lever.

The horizontal table-frame 2O is provided with a series of two or more cross-bars 29, which are secured firmly to the longitudinal rails of said table-frame, and these cross-bars have the horizontal track-rails 30 secured firmly thereto. by the table-frame to travel transversely across the latter in order to present the log to This transversely-movable carriage is provided with wheels 32, which are journaled in suitable brackets on the under side of the carriage, and said rolls are adapted to the track-rails 30 to guide the carriage in its transverse movement on the table frame. The track-rails may be flanged to receive grooved wheels; but this is not essential, because the track-rails may be channeled for the reception of wheels with smooth treads. To effect the lateral or transverse movement of the log-carriage on the table-frame independently of the mechanism by which the saw is reciprocated, I employ1 a drop-weight 33, to which is fastened one end of a cable, rope, or chain 34, which is led around the guide-pulley 35 and through a slot 36 for attachment to the carriage. The guide-pulley 35 is journaled in a bracket, which is fastened to one side of the table-frame in a position for the rope or cable to travel over the guide-pulley, and this drop-weight is disposed at one side of the table-frame so as to normally pull the carriage in a direction to hold the log up to the working edge of the reciprocating saw.

The carriage 31 is provided with means for holding the log against rolling when the saw is operating thereon, and in the simplest embodiment of this log-retaining device I employ a pair of vertical perforated holding-bars A log-carriage'31 is supportedA 37, which are secu rel y fastened to the carriage near the end thereof which lies adjacent to the reciprocating saw. These vertical fixed bars 37 are spaced on the carriage to receive the log between themselves, and in connection with said bars an adjustable clamp-bar 33 is employed to press against the top side of the log on the carriage. This clamp-bar is provided at one end with a pintle or stud 39, adapted to be fitted in any one of the series of apertures on one of the perforated bars, and to the clamping-bar is connected a keeper 40, which may be slipped over the other perforated bar in order to hold the clamp-bar in place on the pair of holding-bars 37.

The operation may be described as follows: The supporting-frame 12 is securely fastened to the tower 10, and the driving-lever is fulcrumed on the post 13 and pivotally connected with the reciprocating rod. The sawmillframe is placed in a position beneath the overhanginglong arm of the drivin g-lever,and the pitman is connected with the saw-frame and with the long lever-arm. The apparatus is now in condition for service, and a log is placed on the carriage 31 between the holding-bars 37 after which the clamping-bar 33 is connected by its pintle and the loop or keeper 410 to the holding-bars. The carriage occupies a position on the table-frame to present the log to the working edge of the saw, and in this position of the carriage the cable or chain 34 is drawn upon to elevate the dropweight. The pump-rod is reciprocated by the working elements of the Windmill, and the lever transmits the motion of the rod to the saw-frame to reciprocate the saw and cause it to cut through the log at right angles to the grain of the Wood. The drop-weight pulls on the carriage to advance the latter and the log as the work of sawing progresses, and the drop-weight thus holds the log in proper position to the saw for the latter to cut entirely through the log. After a length or section of `the log has been sawed ed the carriage is returned by hand to its initial position, the

clam ping-bar 38 is released, the log is moved lengthwise on the carriage a proper distance, and the clamping-bar readj usted, after which the operation of cutting off a length of the log is renewed.

It will of course be understood that the vpump-rod ll is disconnected from the pistonrod of the pump when the sawing mechanism is to be operated by the windmill.
