SAWING-MACHINE.

Specification of Letters Patent.

Application led. May 4, 1912.

To all whom t may concern Be it known that I, JAMES R. BINNS, a citizen of the United States, and a resident of Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Sawing-IIachineavof which the following is a full, clear, and eX- act description, such as will enable others skilled in the art to make and use.

My invention consists of an improved sawing machine designed and calculated to cut rods of wood preferably of cylindrical form into lengths of any desired size.

The objects of the present invention, are first, to provide means whereby a series of rods may be attached and carriedI by the machine, second, to provide means for sawing the rods so carried by the machine into the desired lengths and of uniform length, third, to hold the rods during the time they are being sawed, and fourth, to hold the portions sawed from the rods for a short interval of time and then releasing the sawed portions, and also releasing the remaining portions, of the rods during the time they are carried by the machine so as to bring the rods into position to be again sawed. These objects together with other objects I accomplish by the mechanism illustrated in the accompanying drawings, in which:

Figure 1 is a top plan view. Fig. 2 is a side view. Fig. 3 is a transverse vertical section on line f-3, Fig. 1. Fig. 4 is a perspective view of one of the combined rod holders and belt carriers and a portion of one of the wheels to which the holders are attached. Fig. 5 is a view showing a portion of the lowermost wheel and a portion of the base illustrating the position of the stripper blade.

Similar numerals of reference indicate corresponding parts in all the figures of the drawing.

In the accompanying drawing, 1 represents the lower base plate or frame which is supported at the required height by means of the posts or standards 2, which posts or st-andards rest upon a suitable foundation of any desired construction. To the top or upper ends of the posts or standards 2 is connected the upper base 3. The base or frame 1 is provided with the bearings 4, in which bearings is journaled the power shaft 5, to which power shaft `is securely mounted a drive pulley 6. The power shaft 5 is provided at its inner end with the beveled pinion 7, which pinion meshes with the beveled gear wheel 8, which beveled gear wheel is securely attached in any convenient and well known manner to the upright shaft- 9. To the upright shaft 9 is securely attached whatmight be termed t-he platform or rod supporting and gage wheel 10, said wheel being preferably located just above the uppermost base or frame 3. This supporting wheel 10 should be so adjusted with reference to the uppermost base 3 that it will be free to rotate with the shaft 9. A short distance above the platform wheel 10 is located the wheel 11 and a short distance above the wheel 11 is located the wheel 12, said wheels 11 and 12 being substantially alike in construct-ion and size.

Directly above the wheel 12 is located the wheel 13,which wheel is provided with the adjustable rod carrying heads 14, `best illustrated in Fig. 1. The various wheels 10, 11, 12 and 13 are securely mounted upon t-he shaft 9 in any convenient and well known manner such as commonly used in fixing wheels upon shafts designed to impart rotary motion to the wheels by the shaft to which they are attached.

To the peripheries of the wheels 11 and 12 are attached the combined rod holders and belt carriers 15, said carriers being preferably connected by means of slotted arms 16 and suitable clamping bolts 17. The heads 15 are provided with the side flanges 18, which anges are so located with reference to each other that V-shaped recesses or vertical grooves will be provided and into which grooves the rods designed to be sawed arel seated. The flanges 18 are provided with the cut out portion by means of which grooves-located at substantially right angles to the vertical grooves are provided. These horizontal grooves or recesses are for the purpose of receiving the bands 19 and 20, which bands are held in close contact with the heads 15 during the time said heads are in engagement with the bands. For the purpose of snugly holding the bands upon the heads 15 they are extended to one side of the wheels 11 and 12 a short distance and located aroundthe idlers 21 and 22, which idlers are journaled upon suitable bearings 23, which bearings are connected to the rock arms 24 and 26, said rock arms being securely mounted upon the rock shafts 26 and 27, said rock shafts being properly journaled in the upper and lower base plates or frames 1 and 3. To the rock shafts 26 and 27 and below the rock arms 211- and 25 are securely attached the arms or pull bars 23 and 29, said arms being preferably located just above the lower base or frame 1. For the purpose of holding the bands 19 and 2O tant so that said bands will hug and hold the rods designed to be sawed at the proper times the springs 30 and 31 are provided, which springs are connected to the base 1 or its equivalent and to the outer ends of the arms 28 and 29, said springs being so tensioned that they will hold the rock arms 24 and 25 together with the idlers carried thereby in such a position as to hold the bands 19 and 20 in proper taut condition to snugly hold the rods, but at the same time allowing the yielding` of the bands to compensate for any variance produced by an increased or decreased number of rods or for different sizes of rods.

yAt one side of the rotary wheels 1() and 11 is located the vertical shaft 32, which shaft is journaled in suitable bearings fixed to some part of the frame preferably to the lower base plate 1 and the upper base 3, but this is immaterial except that the shafts 32 should be so located that a proper sized saw 33 when properly attached to the top or upper end of the shaft 32 will be so attached that as the rods are carried around, the saw will eut the rods.

For the purposev of imparting rotary motion to the saw 33 the shaft 32 is provided with the pulley 34 which is driven by the belt 35 or its equivalent. ln the accompany ing kdrawings I have illustrated a power shaft 36 lupon which is mounted the wheel 37, said shaft 36 being driven from any source of power. It will be understood that other methods of gearing may be employed todrive the saw shaft 32 without departing from the nature of my present invention inasmuch as the particular feature of actuating the saw is mechanical.

In use the various rods designed to be cut are placed in vertical position through suitable apertures formed in the carrying heads 14. The preferablepoint or place of feeding the rods being at a point where both the belts 19 and 20 are spaced a short distance from the rod and belt carriers 15 or at or about the point A, Fig. 1 as the various wheels 10, 11, 12 and 13 revolve. After a given rod has been placed in position as illustrated in the drawing it will be car- `ried around with the various carrying wheels, the bottom or lower end of each rod resting upon the platform wheel 10, which platform wheel acts as a gage to hold the rods so that the portions cut off from said rods will be of exact uniform length. As the various wheelsrevolvethe bands 19 and 20 will come in contact with the outer surfaces of the various rods, thereby clamping and holding the rods during the time they are being brought toward the saw 33, the lowermost band 20 irst gripping the rods and the upper band 19 later gripping the rods, both bands being brought into gripping action prior to the time the rods are brought into contact with the saw 33 by which arrangement and turning the rods are gripped both above and below the saw at the time the saw is in cutting action. After the saw has cut a particular rod the portion located below the saw will be gripped and held by the lowermost band and the portion above the saw will be gripped by the uppermost band, but as the various wheels 10, 11, 12 and 13 are revolved in a horizontal plane the severed portions of the rods will first pass from the gripping action of the bands and be released, after which as it is carried around by the platform or support it will be forced oft' from said platform by means of the blade 3T when it falls into the chute 38 or a receptacle by which arrangement the sawed portions of the various rods are properly gathered into a suitable receptacle as the wheels carrying the rods continue to revolve the uppermost band 2O is released from its gripping action and the rod permitted to fall or move downward until its bottom or lower end strikes the revolving platform or wheel 10 and when brought into action with the saw the second time the portion below the saw is cut the action being continued until the entire rod and in fact all of the rods earried by the various wheels have been eut into the desired length or sections.

For the purpose of providing means for cutting dierent lengths for different purposes suoli as various kinds of handles as awl handles, screw driver handles and the like, the shaft 32 is adjustable up and down by means of which the saw 33 is brought to or from the supporting platform 10, the length of the sawed sections being equal to the distance between the saw 33 and the top surface of the plat-form or wheel 10.

For the purpose of holding `the shaft 32 in fixed and desired adjustment the clamp collar 39 or its equivalent is provided which clamp collar rests upon the upper surface of the upper base 3. For the purpose of feeding various sized rods such as Ll0 the carrying heads 14 are adjustably connected to the wheel 13, the apertures formed in said carrying heads being of sufticient size to receive the maximum sized rods designed to be sawed, it being understood that the side ianges 1S will permit various sized rods to be properly held by reason of the V- shaped arrangement of said tianges.

It will be understood that the various rods designed ,to be eut into sections should be held at right angles to the plane of the saw and in order to provide for proper adjustment the heads 14 are provided with the slots 14a through which slots clamping bolts 141 are passed. The arms 16 of the heads 15 are also provided with the slots 16a through which slots suitable clamping bolts 16b are passed. The main purpose for providing adjustment of the heads 15 is to bring a pair of heads directly above each other so that when the two bands 19 and 2O clamp the rods they will be brought into true vertical positions, but it is not absolutely necessary to adjust the heads 15 for diiferent sized rods, owing to the fact that the heads 15 are so arranged that when the rods are properly seated in the respective heads they will be in true vertical position regardless of the size of the rods.

Having fully described my invention what I claim as new and desire to secure by Letters Patent, is

1. In a sewing machine of the class described', the combination of a frame, a vertical shaft journaled in said frame, a series of wheels mounted upon said vertical shaft, the lowermost one of said wheels adapted to support a series of rods, two wheels of the series provided with combined belt holding and rod carrying heads, idle pulleys spaced from the wheels, said pulleys journaled upon rock arms, rock shafts journaled in the frame, said rock shafts provided with pull arms, springs connected to said pull arms, belts located in different horizontal planes and means for rotating the shaft carrying the series of wheels secured thereto and a saw located in the path of the rods carried by the wheels, substantially as and for the purpose specilied.
