THOMAS B. BLACK, 0F STONEHAM, MASSACHUSETTS.
AXLE-TURNE'R AND SCREW-CUTTER.
SPECIFICATION forming part of lLetters Patent No. 230,395, dated July 27, 1880.
Application filed October 31, 1879.
To all whoml it may concern:
Be it known that LTHOMAS B. BLACK, of Stoneham, in the county' of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Axle-Turners and Screw-Gutters; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the artto which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.
This invention relates to a new and useful portable tool for the purpose of turning and screw-cutting the ends of carriage-axles, as may be required when, by the Wearing of of the ends of the axle-boxes, the latter, as well as the wheels thereon, become so loose as to move laterally in relation to the axles. In such cases it has been customary heretofore to place one or more washers between the end of the worn axle-box and the inner face of the nut, and in most cases to discard the 01d axle and replace ,it with a new one. These contrivances are more or less objectionable, and to obviate these difficulties is the object of my invention, by means of which, when an axlebox is worn too short, the wheel is disconnected from its axle and my improved tool located thereon in such a manner that by rotating it around its axis the axle can easily be turned down and shortened to correspond with the length of the worn axle-box 5 after which the screw-thread inA the end of the axle is lengthened accordingly, so as to allow the face of the nut to be turned close up to the outer end of the axle-box. If so required, the projecting end of thescrew-threaded part of the axle may be finally turned off by this my improved tool, as will hereinafter be more fully shown and described.
The invention is fully represented in the accompanying drawings, in which- Figure l represents a side view, and Fig. 2 represents a plan view, of my improved turning and screw-cutting tool. Fig. 3 represents a central longitudinal section thereof. Fig. 4 represents a cross-section on the line A B,
5o shown in Figs. 1 and ZK; and Fig. 5 represents a section of the apparatus, showing the positions of the screw-cutting and guide tools for making an increased screw-thread on the axle end. Fig. .6 is a section on the line C D, shown in Figs. l and 3.
Similar letters refer to similar parts wherelever they occur ou the different parts of the by the ends of such set-screws I interpose between the ends of such set-screws and the axle a pair of curved packing-plates, ff, as shown in Figs. 3 and 6, each of which plates is provided with a guide-pin, g, passing through a corresponding perforation in the shell or sleeve.
a is an annular Vgroove on the exterior of the sleeve a, which, in combination with the adjustable angular guide-piece h on the rotary head c, serves to prevent the latter from moving endwise during the turning off of the axle or cutting off of the end of the screw part thereof. The guide-piece h is provided with a slot-hole, h, through which a set-screw, h,
passes loosely, and is screwedinto the head c,
as shown, by which arrangement the relative positions of the rotary head c and stationary sleeve c lnay be changed according to the amount that is to be turned or cut olf fromthe axle. The angular guide-piece h is removed from the head c during the operationl of cutting a new screw-thread in the end of the axle.
In Fig. 4 i represents the cutting-tool, that is made to rest in a perforation, c', made in the. side of the head c. 7a is an annular and internally screw-threaded projection on the exterior of the head c, which projection is provided with a pressure-screw, l, as shown, for
IOO
the purpose of feeding the cutting-tool toward the axle in the ratio as it is turned off. m is a set-screw for the purpose of securing the cutting-tool in position during the operation of turning the axle. A similar annular and internally screw-threaded projection, k', with its pressure-screw l and setscrew '1n',islocated opposite the tool i, as shown in Figs. 4 and 5, which serres'to retain and secure in position the screw-cutting tool i', (shown in Fi 0. 5;) and in said figure i" represents a guidetool, the inner point ot' which is intended to rest in the old screw-thread in the outer end of the axle, and to serve as a guide for the screw-cutting tool 'i' in its rotation around the axle.
This in v improved turner and screw-cutter is equally well adapted for cutting right and leit hand threads, as is required for the two opposite ends of an axle.
All that is required for the purpose of turn'- ing olf a portion of the axle, or to cut off' a part of the screw-threaded outer end of the axle, is to center and secure the sleeve a. in position on the axle, as shown in Fig. 3. The cuttingtoolt' is then secured within the rotary head c, in a manner as described, and the latter is gaged, by means of the guide h and its setscrew 11.", in relation to the sleeve a according to the amount that is to be cut oli' from the axle. When this is done I removev the guide h, as well as the tool z', and insert and secure the screw-cutting tool i" and screw-guide fi, in a manner as described. The tool, as well as the head c, is in both cases rotated around the axle, operated upon by manual power applied to the handle d, as heretofore described.
I am aware ofthe patent granted to F. F. Goltey, February l1, 1879, No. 212,212, and I wish to state that I do not claim any device therein shown and described; but
What I desire to secure by Letters Patent, and claim, isi l. The herein-described turning and screwcutting tool consistingof the stationary sleeve a, set-screws e e, groove c', guide h, and the rotary tool-holder c, with its handle d, as and for the purpose set forth.
2. In combination with the stationary sleeve a and the rotary tool-holder c, the set-screws c e, the packing-plates f f, and the guidepins g g, all combined and arranged substantially as and for the purpose set forth.
In testimony that I claim the foregoing as my own invention I have axed my signature in presence of two witnesses.
THOMAS B. BLACK.
