UNITED STATES PATENT OFFICE.
JAMES R. KAIN, OF TIFFIN, OHIO.
APPARATUS FOR CUTTING SCREWS ON BEDSTEAD-RAILS.
Specification forming part of Letters Patent No. 10,254, dated November 22, 1853.
To all whom it may concern.-
Be it known that I, JAMES R. KAIN, of Tiffin city, in the county of Seneca and State of Ohio, have invented a new and useful Improvement in Machines for Cutting Screws on Bedstead- Rails; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, forming part of this specification, in which Figure 1 is a side elevation of the machine. Fig. 2 is a top view of the same. Fig. 3 is a front elevation. Fig. 4. is a section on line w :10, Fig. 1. Fig. 5 is an enlarged view of the cylinder and V-cutter. Fig. 6 is a section Fig. 7 is a section upon line 2' z, Fig. 6.
Similar lettersin the several figures refer to the same part of the machine.
My invention refers to improvements in machinery for cutting screws on bedsteadrails; and it consists in the method of securing the rail in the machine by means of spiral-faced plates with points on their inner faces attached to and movable by a springlever, the arrangement being such that the securing-points advance simultaneously an equal distance on each side of the rail, thus keeping its axis at all times coincident with the axis of the cylinder, and enabling the machine to hold rails-of various sizes simply and effectively.
My invention further consists in the method of changing the right and left nuts and keeping them in position by means of a springcatch and notched tie -piece, which holds firmly the required nut against the screw. which, as in other machines, is made with a double thread.
In the drawings, a is the cylinder, in which I insert the V-cutters b and b for cutting both right and left screws by reversing the cylinder upon the head of the double-threaded screw 0, the nuts d and d of which are movable about the pins 6 and c, and are held together by the tief, having on its under edge the notches g and g, by which the springcatch it holds either of the nuts against the screw 0.
In front of the machine are the horizontal arms Z and Z, having on their inner surfaces the spirals m, upon which work the securingplates n and n, the exterior faces of which are of a spiral form to fit the faces of the arms ll. Theyturn upon the pins 0, passed through the arms. The inner extremities of these pins are pointed for fastening the rail. The plates 01, and n are fastened to the spring 10, which keeps them in position and serves as a lever for their movement.
The V-cutters b and b are secured in the cylinder a in the following manner: In the front extremity of the cutter are the pins g, which enter corresponding holes in the cylinder and prevent all movement of that portion of the cutter. The rear of the cutter is notched to embrace the cylinder, which at this point is slightly beveled, as seen in Fig. 6. The cutter being thus inserted, between the rear of the cutter and the edge of the opening in the cylinder in which the cutter is placed is inserted the wedge at, which drives forward the cutter and effectually secures it in the cylinder.
The operation of my improvement is as fol lows: The main features of this machine be lng similar to methods in common use and well understood will not require particulardescription. The screw 0 is operated in the usual manner, the desired nut being held against the screw by the catch it entering one of the notches g g, according as a right or left screw is required. The rail is placed in the prolongation of the axis of the cylinder a, the spiral faces of the plates at and n being held by the corresponding spirals on the arms Z Z. WVhen the rail is adjusted in position, the lever 19 is carried in the direction of the arrow, drawing the plates 02 and 'n' equally together and holding the rail by the entrance of the points of the pins 0 into its faces. The cylinder ct is prevented from turning upon the screw 0 by the stop y upon the screw, which fits into the notches oin each extremity of the cylinder, admitting of the cylinder being reversed in position for cutting both left and right screws.
The simplicity of the entire machine and the effective manner in which it works will cause it to be readily appreciated by all persons in any degree skilled in screw-cutting. The V-cutter is so secured that not the least motion can be imparted to it during the operation of cutting, while at the same time it plates n n with the arms Z Z and springp, for securing the rail in the machine, as specified.
2. The catch h, in combination with the notched tie f and pins e e, substantially as specified, for carrying the right and left nuts against the screw and securing them in position, as set forth.
In testimony whereof I have hereunto signed my name before two subscribing Witnesses.
