APPARATUS FOR USE IN UNITlNG IRON AND STEEL PLATES.
SPECIFICATION forming part of Letters Patent No. 788,888, dated May 2, 1905.
Application filed May 25.1904. Serial No. 209,765.
To all 1071,0121, 1125 nut/g concern:
Be it known that 1, WILLIAM Cnoss, residing at WVinnipeg, in the Province of Manitoba, Ianada, have invented certain new and useful Improvements in Apparatus for Use in Uniting Iron and Steel Plates, of which the follow ing is a specification.
My present invention relates to a certain new and improved tool for use in uniting iron and steel plates in boiler construction and the like, and it particularly seeks to provide a device of this character in which the plates to be joined are tightly held in their correlative position and may be alternately drilled and tapped and a plug or bolt inserted into the drilled and tapped apertures.
With other objects in view, which will be hereinafter apparent, the invention comprises certain novel construction and combination of parts, all of-which will be first described in detail, and then specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure 1 is a side elevation showing my improved tool in use for drilling the plug-apers ture and showing how the patch is tightly held againt the boiler-plate during the drilling, &c., process. Fig. 2 is a longitudinal section of the drill. Fig. 3 is a cross-section on the line 33 of Fig. 2. Figs. ft, 5, 6, and 7 are cross-sections on the lines 4: 4. 5 5, 6 6, and 7 7 of Fig. 2. Fig. 8 is a detail view hereinafter referred to.
Referring now to the accompanying drawings, in which like numerals and letters of reference indicate like parts in all the figures, 1 designates the boiler fire-box, which may be of the ordinary construction and which per 86 forms no part of this invention.
hen my invention is used in patching locomotive boxes, boilers, and the like, the patch-plate 2 is formedin any desired shape, depending upon the nature of the break in the boiler, and includes the ordinary stay-bolt apertures 52, as shown. interposed between the patch-plate and the main plate is any suitable liner 3. (Shown in detail in Fig. 8.) I first secure the plate in its place with temporary bolts an eighth of an inch less in diameter than the standard to be used to secure the the same time.
patch, the liner being placed in position at l then adjust the drill and tapping-machine over the place where the hole is to be drilled and force it hard against the plate to hold the patch-plate firmly against the copper liner and the boiler-plate. The patch-plate will at the same time be firmly beaded upon the copper joint by the use of a hammer. After the drilling-machine has been placed in position the hole is drilled and then tapped, and the screw'plug is then inserted, all of which operations will be presently more fully explained.
By reference to Figs. 1 to 7, inclusive, it will be seen the drilling-machine comprises a body portion or frame 5, from which the laterally-extending radial arms 5 5", extend in opposite directions. The arm 5 terminates in an elongated eye portion 6 to permit of the insertion of the drill-holder-adjusting screw 7, which has a spherical head '7, apertured, as at 7, to receive a rod for turning the same. The arm 5 from the eye 6 to where it joins the body 5 has a longitudinal bore 6, threaded, as at 6", to receive the screw 7, and enlarged, as at 6, to receive a frame and guideway for the drill-chuck-earrying shaft 8, the end 8 of which shaft 8 iits the bore 6 and is provided with a semispherical indentation or pocket 8 at its end to coi'iperate with the correspondingly-formed end '7 of the screw 7 To the extreme end of the eye portion 6 is integrally formed an extension 6", threaded, as shown, to receive the elongated turningsleeve 6", which is formed with wrench-receiving faces 6 and a plate-engaging point or center 6' by means of which sleeve and its screw connection the tool is tightly forced against the plate to cause it to become tightly seated against the patch and the boiler-plate during the operation of boring, tapping, and inserting the securing-plug.
The arm 5" extends in a direction diametrically opposite to the arm 5 and in alinement therewith, and the said arm 5" is provided with a longitudinal bore 5, through which the drill-chuck-carrying shaft 8 passes, and this here 5" is enlarged, as at 5. The bore 5 is circular in cross-section to form a guideway for the shaft 8, and the enlarged bore 5 is also circular in cross-section to form i be broken off to leave the plug as shown in a guideway from the drill-chuck 8 which is secured to the end of the shaft 8 and which is susceptible to longitudinal adjustment. in the bore 5. The arm 5, where the enlarged bore 5 begins, is cut away, as at 5", to permit of ready access to the chuck to insert or remove the drill, tap, or plug, and the end of the arm 5" is formed with a head or hammer portion 5*, which is likewise circular in crosssection, but which is cutaway on one side, as at 5', to form a sight-opening.
Reverting again to the shaft 8, it will be seen the said shaft is provided with a longitudinal groove 8 to receive the key 8, which has shoulder portions 8 8 and is so formed as to be received by the key-slot 8 of the pinion 8 mounted on the shaft 8 within the body portion 5, which body portion 5 is in the nature of a ring or circular frame and is also provided with a hub 10 at right angles to the arms 5 5, but in the same plane therewith. The hub 10 is apertured to receive a stub drive-shaft 11, to which is keyed the pinion 12, which pinion 12 meshes with the pinion 8 whereby when motion is imparted to the drive-shaft 11 the same will be transmit-' ted, through the pinions12and 8", to the drillcarrying shaft 8. The shaft 11 is also provided with a squared end 11 to receive a crank 12 or other power-transmitting means.
After the patch has been put into position and the tool adjusted with respect to the place where the hole is to be drilled, as before indicated, the desired tension or pressure is brought to bear on the patch at this point to hold the same, as well as the drill, in place during the boring, tapping, and plugging operation by means of the sleeve 6 After placing the required drill D (see Fig. 1) in the chuck power is applied to the shaft 11, which is transmitted through the pinions 12 and 8 to the shaft 8 to impart rotary motion thereto to operate the drill, the desired feed of the drill being given through the medium of the screw 7. After the aperture has been drilled the drill is withdrawn therefrom and removed from the chuck and a tap is inserted in the chuck in the place of the drill without removing the machine from its position. The hole having been drilled is then tapped by operating the shaft 11, and through the gears 12 and 8 the shaft 8, as before. As soon as the desired tap is made the shaft 8 is reversely rotated to remove the tapping-tool from the bore, which tool is then removed from the chuck and replaced by a steam-tight plug 4, which is provided with a squared end 15 to enter the chuck and a threaded portion 4 to enter the tapped bore of the patch-plate, the copper liner, and the boiler-plate. This plug is provided with a circumferential groove or nick 4:, whereby after the plug has been screwed in the previously-tapped bore by rotating the shaft 8 the squared portion 15 may Fig. 2. The tool is then removed from its present position and adjusted in another place for performing the next boring, tapping, and plugging operation at another point, all of which operations are performed in the same manner as for the first boring, tapping, and plugging operation.
From the foregoing description, taken in connection with the accompanying drawings, it is thought that the complete construction, operation, and many advantages of my invention will be readily apparent to those skilled in the art to which it appertains, and I desire to say that I do not confine myself to the exact construction and arrangement of parts, as it is obvious that slight changes in the detail construction, arrangement, and combination of parts may be made without departing from the scope of the invention or the appended claims.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
