ALEXANDER DJIDICS, OF NEW YORK, Y.
NURLINGr-TOOL.
Specication of Letters Patent.
Patented Jan. 20, 1920.
Application filed February 10, 1919. Serial No. 276,152.
IThis invention relates to nurling tools,
and has for its object to provide a tool of this kind which may be applied to and retained in contact with the work by hand.
In order to relieve the hand from strain where the work to be done'consumes considerable time, means are provided Jfor rigidly locking the jaws of the tool at any desired adjustment. Means are also provided for yieldingly vholding the jaws in position to engage work of unevenccontour. Another object is to increase the range of ad-' justment of the jaws. Further objects will appear as the description proceeds.-
The invention will be first hereinafter described in connection with. the accompanying drawings, which constitute part of this specification, and then more specifically defined in the claims at the end of the description.
In the accompanying drawings,y wherein similar reference characters are used to designate corresponding parts throughout the several views:-
Figure 1 is a side elevation of a tool constructed substantially in accordance with this invention.
Fig. 2 is a central longitudinal section taken vertically of the tool, the outer ends of the spring arms being broken away, and
Fig. 3 is a section on the line III-III of Fig. 2.
A coupling member 1 is rigidly fastened.' to one jaw 2 of the tool, as by the rivets 3. Said jaw 2 has a recess formed at 4 in its inner longitudinal face, and in this recess there are journaled two spaced nurling lwheels 5, as by the cross lpins 4or shafts 6.
The recess 4 may extend to the end of the jaw` 2 and lhave the coupling member 1 seated therein, as shown in Fig. 2. The outer end portion of the jaw 2 is suitably finished to serve asa handle 7 and has a screw-threaded bore 8 in its end.
Another jaw 9' is pivotally connected to' the coupling member 1 by a pivot pin 10 engaging one of a plurality of spaced holes 11 in said coupling member, whereby a wide:
range of adjustment of the jaw 9 may be made with respect to the jaw 2. The jaw 9 has a recess 12 in. its face opposite the recess 4 in the jaw 2, and in the recess 12 a single nurling wheel 13 is j ournaled, as by the cross pin or sha-ft 14,said wheel 13 being disposed opposite the intervening` space between the pair 'of wheels 5 and overlapping portions of said-wheels, as is usual. The jaw 9 vhas its end portion 15 linished to serve as a handle which normally extends substantially parallel to the handle 7 of the jaw 2. A screw-threaded bore 16 is formed in the end of the handle 15 similar to the bore 8 in the handle 7 It is obvious that the two handles 7 and 15 may be grasped by the hand of the operator and the necessary pressure exerted thereon to hold the nurling wheels 5 and 13 in contact with the work 26. Should the strain become too great on the hand, the jaws may be locked in'. any desired adjustment by means of the connecting bar 20 which is passed loosely through passages '21 and 22 in the jaws 7 and 9, respectively, retainedv at one end by the cotter pin 23 and screwthreaded at 24 at its other end to receive the adjusting nut 25.:
When the work is of uneven contour, that is, has portions of different diameters or is elliptical in cross section, the jaws may be yieldingly held in contact with the work by placing spring arms 17 in the bores 8 and 16 of the jaw handles and connecting the ends of said arms with a link 19. The ends of the spring arms 17 have heads or knobs 18 to retain the "link 19 thereon. Links of assorted lengths :may be kept on hand to allow for a 4wide range of adjustments. When the spring arms are used, the nut 25 is loosened on the `connecting bar 24, as shown in Fig. 1, so that thejaws may spread to conform to the contour of th'e work, the arms 17 being bowed as this spreading takes place and resuming their normal strai ht positions when the minimum diameter og the work is reached. Of course, the spring arms may also be utilized for exerting spring pressure on a piece' of work of uniform contour, if desired. The piece of work illustrated at 26 is only one of many kinds that may be operated upon by the tool.
I-Iaving thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is l. In a nurling tool, the combination with a pair ofy jaws carrying cooperating nurling.
wheels, of handles on said jaws adapted to he grasped together in the hand of the operator for the purpose specified, and means for yieldingly connecting said jaws together. 2. In a nurling tool, the combination with a pair of jaws carrying coperating nurling whe-els, of handles on said jaws adapted to be grasped together in the hand of the operator for the purpose specified, spring arms detachably connected to the jaws, and a link for connecting said arms together.
3; In a nurling tool, the combination with i.
a pair of jaws carrying coperatin nurling wheels, of handles on said jaws a apted to be grasped together in the hand of the operator for the purpose specified, there being bores in the handles, spring arms adpted to ybe inserted in said bores in the handles, and
a link for connecting together the outer end portions of said arms.
4. In a nurling tool, the comblnation with a pair of jaws carrying coperating nurl-v ing wheels, of handles on said jaws adapted to be grasped together in the hand of the operator for the purpose specified, spring arms adapted to be attached to said handles, a link for connecting together the arms, and means on the ends of the arms for retaining said link thereon. 5. In a nurling tool, the combination with a pair of jaws carrying cooperating nurling wheels, of spring arms attached to said jaws, and a link for connecting said arms together for the purpose specified.
6. In a nurling tool, the combination with a pair of jaws carrying co erating nurling wheels, of means for rigidly connecting said jaws together, and means for yieldingly connecting said jaws for the purpose specified. 7. In a nurling tool, the combination with a pair of jaws carrying coperating nurling wheels, of a coupling member rigidly connected to one jaw and having a series of spaced holes for pivotally and adjustably 'connecting the other jaw thereto.
In testimony whereof I have signed my name to this speciiication.
