MACHINE FOR CUTTING I'ENON S.
SPECIFICATION forming part of Letters Patent No. 416,608, dated December 3, 1889.
Application filed October 16, 1888. Serial No. 288,247.' (No model.)
To all whom it may concern:
Be it known that I, ARTHUR HENDEY, a citizen of the United States, residing at Denver,
in the county of Arapahoe and State of 0010- rado, have invented certain new and useful Improvements in Machines for Cutting Tenons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to machines for cutting tenons on either round, square, or other timber for use in mines.
For timbering shafts and slopes in mines round timbers answer a satisfactory purpose, provided the tenons on the opposite ends of such timbers are in line with each other and the shoulders of such tenons are parallel.
- The object of my invention is the production of a machine adapted to simultaneously cut tenons on the opposite ends of timber and having the capacity for ready adjustment of the diiferent parts, whereby the machine is adapted forcutting tenons on timbers of varying sizes and lengths.
The invention, as shown, is duplex in character-that is to say, there is a tenon-sawing machine or gang of saws at both ends of the machine, for the purpose of multiplying the capacity of the machinesaving a handling of the timber to bring both ends within the range of one set of saws, and for the main purpose of more certainly securing the alignment of the tenons on the opposite ends.
' The invention consists, essentially, in the means for adjusting the different parts of the machine to and from each other, which will be hereinafter particularly described, and pointed out in the claims.
In the drawings, Figure 1 is a view showing the ground plan or horizontal arrangement of the mechanism. Fig. 2 is a side elevation, looking from the feed side of the-machine.
Fig. 3 is an end elevation of the machine' Figs. 4 and 5 are enlarged views of the headblock and log clamping or gripping device. Figs. 6 and 7 are section and elevation, respectively, of a spring-catch for locking the angle-block to the carriage.
A is the bed-plate or frame of the machine secured to base-timbers or frame work in any suitable substantial way. Fixedly mounted at one end of the bed-plate A and adj ustably mounted near the other end are tenon-sawing machines or gangs of saws, each machine or gang having saws arranged in pairs, the pairs being arranged at right angles with each other, one to cut the sides and the'other to cut the shoulders of a tenon.
G C are ways or tracks arranged at right angles with and above the bed-plate A of the machine. The movable sawing machine or gang is connected with the track or way C,
and both are adjustable toward or from the fixed trackand machine to provide for varying lengths of timbers by means of a rack c and pinion c or other equivalent mechanism. The tracks or ways C and O are grooved and slotted beams, substantially as shown in Figs. 1 and 4. In the grooves of the tracks there are mounted traversing carriages D D, consisting of flanged or headed bases (1 d and risers d d. (Shown in Figs. 2, 4, and The flanged heads 0. fit in corresponding grooves in the tracks, and connected therewith is a rack-bar d as shown. The upper edges of the risers d d are concaved to form saddles or seats for oscillating crescent-shaped logholders, which, in connection with their supporting-carriages D D, correspond in function with'the head-block of a saw-mill.
The log adjusters or holders have crescentshaped parts E fitting in the saddle of the carriages D. Each of the angle-blocks hasa pair of dogs e e pivoted thereto for gripping and securing thelog in the angle of the same, as seen in Figs. 3 and 5. The part E has formed therein a concentric groove, into which a stud 8 projects for holding it in its saddle. Said part E is also provided with perforations or recesses, and a spring-stop H (shown in Figs. 6 and 7) interlocks therewith the tenons are mounted on arbors carried by a frame F, which is itself pivoted and adjustably clamped in pillars G, as particularly shown in Fig. These saws, mounted as shown, are readily adjustable by swinging their carrying-frames F to bring their edges more or less distant from each other. Saws h h, for cutting the sides of the tenon, are also adjusted by removable collars in a wellknown way, a complete set being provided to cut from one to twelve inch tenons.
e is an angular bolster applied to the angleblock to provide for bringing the center of logs of different diameters approximately to the center of the arc of the log adjuster or holder. For small logs a series of these bolstersone outside the other-may be used, or a series of bolsters of diiferent dimensions may be used.
1 is a hand-wheel attached to a shaft extending across the machine. The shaft carries pinions which intergear directly with rack-teeth beneath the traversing carriages or with pinions C The carriages D D are thus traversed to move the log past the saws and back again.
In operation the movable gang of saws and movable track are first adjusted on the main bed-plate or frame of the machine to the length of the timber to be tenoned. A log is then adjusted and dogged in the angle-blocks. The log is now passed through the saws and back, and the sides and shoulders of a tenon are cut on both ends of the log. The spring catch or stop is now pulled out and held by a quarter-turn of the handle. The log, together with the angle-block, is now rolled slightly, the spring-catch released, and the rolling is continued until the stop snaps into place to lock the angle-block in the second position. The log is again passed through the saws and back, when square tenons on both ends of the log, of definite dimensions in perfect line with each other and having parallel shoulders, are simultaneously produced.
By the means herein described the machine may be adjusted to any required length of lumber, so as to out tenons on both ends thereof at the same time. The log can be adjusted to any desired position after it has been secured to the angle-block, and the saws can be adjusted to make any desired size of tenon.
The means of driving'the gangs of saws from a prime motor or driving-pulley is indicated in diagram, Fig. 3, which shows that the swinging of the frame F and the consequent adjustment of the saws a a to or from each other does not change the tension of the. driving-belt, because as much is given out at one point as is taken up at another.
Having now described my invention, what I claim is 1.
