provements in Ratchet-Drills and Screw Threading Devices, of which the followingis aspeciflcaton.V Y
This invention relates "to improvements in.
ratchet-drills and screw threading devices; and it has for 'its object to provide an improvedimplement for the th reading of pipes or cylindrical metal bars with a right or left hand also applicable as a ratchet-drill for drilling purposes, as will hereinafter be more full;T shown and described, reference being had to the accompanying drawings, wherein- Figure l represents atop plan View of the In a perforation in the-frame A is journaled the tubular guide C for thepipe or cylinder that is to be threaded. The upper end of the tubular guide O is made as adie-holder C', in Which the screw-threading die D is contained.
C" is a cover hinged at C8 to the die-holder C' and adapted to be closed on top of the said die-holder and secured in such position when the device is in use as a screw-threading device, as shown in Fig.- 2.
Secured -to or made in one piece with the vsleeve C is a ratchet-wheel C4, which is inscrew, as maybe desired, and which shall he` I5 invention, showin g the cover ofthe die-holder- Fig. et repre- A represents the hollow frame, provided with a handle B, as shown.Y
-frame A is pivoted at e thelpawl E, having lpawl projections E E", as shown in Fig. 3, adapted for engagement with the ratchet- Wheel C4, as shown in Figs. 2 and 3. Back of the pawl E is pivoted at f to the `frame A a block F, through a perforation in which is guided aspring-pressed pin G, the outer end or headfof which is held against the rear of the pawl E by the influence of a coiled spring g, as shown in Figs. 2 and 3. To the outer portion of the pivot of the block Fis secured a knob or handle F', by means of 'which the block F and pin G may be turned from a position shown in Fig. 3 to a position for caus ingan engagement of the pawl projection E with the ratchet-wheel 04, if desired, to rotate the latter and its die-holder and die in a direction opposite to that shown by arrow in Fig. 3. f
It will thus be seen that by the adjustment of the position of the block F and its spindle G the duplex pawl-lever E may be adjusted relative to the ratchet-wheel C4 for turning the latter and its die-holder and die to the right or left, as may be desired, for cutting right or left handed threads. In cutting threads on pipes or bars of less diameters than the interior bore of the sleeve C a suitable guide-thimble is inserted in the latter, as is common in devices of this kind.
' If it is desired to use the invention as a ratchet-drilhl remove the screw-threading die D from within the die-holder C' and use in connection with the device a drill-holder. (Shown in perspective view in Fig.4 and shown `in Fig. 5 as connected to the frame of the invention.) Said drill-holder consists of a cylindrical sleeve H, having a socket 7i in its lower end for the reception of the shank of the drill `I. (Shownin Fig. 5.) Within the upper end of the sleeve H- is secured a nut h', adapted to receive the screw-threaded feed-screwr K, as shown, said feed-screw having at its upper portion a head it', terminating as a conical end k', which is adapted lto be held against a 95 suitable rest or Ysupport during the drilling operation, as is common in devices of this kind. The feed-screwK may be turned around its axis either by means of a suit-able Wrench 5o closed Within the frame A. Within'l said or Spanner placed on the head 7e or by means roo of a rod inserted in ahole 7c" in said head, as shown in Figs. 4 and 5. To the sleeve I-I is secured or made integral with it a plate H',
adapted to lit the interior of the die-holder O when the device is used as a ratchet-drill, as represented in Fig. 5.
It will be noticed that the ratchet-Wheel C4, pawl E, spring-pressed pin G, and block F are all arranged inside of the frame of the device, by which said parts are wholly inclosed, so as to be kept clean and protected from dust, grit, or other accumulations by which the efficacy of Working of said parts is materially augmented.
From the above description it will be seen that the invention may be used as a screwthreading device for cutting right or left handed screws, and it may also be used as a ratchet-drill by combining with it the drillholding sleeve H in a manner and for the purpose hereinabove shown and described.
What I Wish to secure by Letters Patent and claim isf l. In a ratchet-drill andscreW-threading device, the combination of the hollow frame A having a circular perforation `in one end, the tubular guide c extended through and journaled in said perforation andliaving an enlarged die-holding' chamber c in one end, the ratchet-Wheel c* secured to said tubular guide and inclosed in the said hollow frame, the reversible paWl E and the perforated block F each pivotally mounted within and wholly inclosed by said hollow frame, the pivotof said block being extended beyond the frame and provided with a handle for adjusting said block, and the spring-pressed pin G mounted in said block and engaged with said pawl, substantially as and for the purpose described.
2. In a ratchet-drill and screw-threading,r device, the combination of the hollow frame A, the tubular guide c journaled in and extended through said frame and provided in one end With the enlarged chamber c', a detachable drill-holder H mounted in said tubular guide c and provided with a plate or projection H to interlock in the chamber c', a drill I carried in one end ofsaid holder and a feed-screw 7c in the other the ratchet-Wheel c4 on the guide-sleeve, o, the reversible pawl E, the perforated block F pivoted in the hol low frame and having its pivot extended outward and provided with a handle, and the spring-pressed pin G mounted in `said block and engaged with said pawl, substantially as and for the purpose described.
In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
JOHN MILLER.
