COMBINATION STUD VICE AND TUBE FLARING APPARATUS Filed Oct. 6, 1958 2 Sheets-Sheet 2 INVENTOR. James James States Patent COMBINATION STUD VICE AND TUBE FLARING APPARATUS James Jones, 222 1st St., Olyphant, Pa. Filed Oct. 6, 1958, Ser. No. 765,595 3 Claims. (Cl. 153-805) My invention relates to improvements in machine shop apparatus and has for its primary object to provide a novel vice form devicewhich is adapted for securely holding the differently threaded ends of the studs while the other ends thereof are being threaded and which is also available for holding one or a plurality of dilferent sized tubes while ends thereof are being flared, the device incorporating preferably detachable means for this latter purpose.

The invention further contemplates a highly eflicient device as characterized which is simple in construction, strong and durable, relatively inexpensive to manufacture, and which can be readily mounted in or removed from a conventional bench vice.

Invention also resides in certain novel features of construction, combination and arrangement of the various parts and in modes of operation thereof, as will be readily understood.

Although a now preferred example of my inventive concept has been illustrated, it is to be understood that same can be variously changed and modified within the spirit and scope of the subject matter claimed hereinafter.

In the drawings, wherein the same reference characters have been used to designate the same parts throughout the several vieWs- FIG. 1 is a top surface-illustrating perspective view of my novel stud or tube gripping vice without the tube flaring member thereof, the vice being adapted to be clamped between the jaws of a conventionalbench vice;

FIG. 2 is a cross-sectional view through the vice of FIG. 1, but showing the tube flaring means assembled therewith;

FIG. 3 is a longitudinal sectional line 33 of FIG. 1;

FIG. 4 is a detail view of a conventional Allen Wrench which is used for operating the screws which hold the vice sections together;

FIG. 5 is a fragmentary sectional view of the vice showing the threaded end of a stud secured in one of the vice-provided holes; and

FIG. 6 is a bottom plan view of the vice of FIG. 1.

Referring to the drawings by reference characters, numeral 10 indicates generally my three section stud or tube gripping vice which comprises the longitudinally coextensive outer sections 11 and 12, and the similarly longitudinally coextensive intermediate section 13. The sections 11, 12 and 13 of the vice are clamped together by the transversely extending screws 15 which are received in the tapped and aligned holes 14, as indicated in FIG. 1. Although only two securing screws 15 are shown, one adjacent each end, it will he understood additional ones can be employed.

As indicated in FIGS. 1 and 6, the outer section 11 and intermediate section 13 of the vice have opposed tapped and nearly semi-circular cutouts which extend the full depth of the sections 11, 12 and provide the differently sized threaded holes 16, 17, 18, 19, and which extend through the vice 10 from top to bottom. These holes provide the respective upper portions 16", 17", 18", 19" and 20" and lower portions 16, 17', 18', 19' and 20' which open from the bottom surface of the vice.

The upper hole portions 16", 17", 18, 19", and 20" view taken on the will be drilled for dilferent standard fine thread sizes such as /2", /s", and A", respectively. However, the corresponding hole portions 16', 17, 18', 19' and 20 which open from the bottom surface of the vice, as shown in FIG. 6, will be drilled for corresponding coarse thread sizes.

The upper portions of the aforementioned holes 16, 17, 18, 19 and 20 which open from the top surface of the vice 10 as shown in 'FIG. 1, will have outwardly flaring entry ends 16a, 17a, 18a, 19a and 20a, respectively, for use in flaring the ends of tubes such as 32 in FIG. 2, which extend through the respective holes 16, 17, etc. This matter of tube end flaring will be referred to later on in connection with the description of FIG. 2.

Also to be noted is the fact. that the upper surfaces of the intermediate section 13 and the other outer vice section 12 also provide the opposed and nearly semi-circular cutouts which provide the different sized holes 21, 22, 23, 24, and 25 which are each of uniform diameter throughout and extend all the Way through the vice 10.

These holes provide the respective differently threaded upper portions 21", 22", 23", 24", 25 and lower portions 21', 22', 23, 24' and 25.

The upper portions of the holes 21, 22, 23, 2 4 and 25 which are provided by vice sections 13, 12 will be: tapped for standard fine thread sizes such as 1", /8", /4 /8, and respectively. On the other hand, the respective lower hole portions 21', 22', 23, 24' and 25 will be tapped for the standard coarse thread.

It should be mentioned that the respective upper and lower portions of holes 16, 17, etc. and 21, 22, etc. are separated by unthreaded portions constituting shoulders 26-, as indicated in FIGS. 2 and 3.

In the construction of the vice 10, the sections 11, 12 and 13 will be assembled with opposed faces in flat contact with one another whereupon the registering holes 16, 17, etc., and 21, 22, etc., will be drilled and subsequently appropriately threaded. However, after the holes have been drilled and threaded as described, the opposed faces of the sections 11, 12, 13 will he milled away substantially so that the opposed holes 16, 21, etc., defining cutouts will be less than semi-circular so as to provide transverse gaps 28 between sections 11, 13 and 13, 12 and of course between opposed halves of the threaded holes when tubes or threaded stud ends are gripped therein. This makes for better gripping as will be obvious. A Any desired number of the section 13, 12 provided holes such as 23, 24 can have entry ends bevelled as indicated at 23a, 24a, for tube flaring, as will be hereinafter explained.

FIG. 5 illustrates a stud 30 having its threaded end 30a gripped in the threads of the hole 16 between the vice sections 11, 13. This stud 31 is in position to have its upper end threaded by a hand operated-die, as usual.

Corning now to the matter of outwardly flaring the end of a tube 32 as indicated in FIG. 2, a tube flaring device indicated generally at 33 is assembled with vice 10. This tulbe flaring device comprises the generally U-form yoke 34 providing the legs 35 having inturned outer end lugs 35a which slidably engage in the longitudinally extending outer surface grooves 42 of sections 11, 12, as shown.

The bight portion of the yoke 34 has the bearing 36 which is oflset closer to one leg 35 than to the other, said bearing 36 receiving the pressure screw 37 having the cone ended tube-flaring head 38 at its lower end. Head 38 provides conical tube-flaring surface 38a. The illustrated offsetting of bearing 36 is to enable the tube-flaring head 38 to properly register with the upper ends of tubes 32 which are seated in holes of the series 21-25 or of the series 16-20.

The upper end of the pressure screw 31 has the block 39 secured thereto as at 40, said block carrying the lever form cross bar 41, as indicated, for operation of pressure screw 37. I

It will be evident from FIG. 2 that when the pressure screw 37 is forced downwardly the conical lower surface 38a of its head 38 will flare the end of the tube 32 outwardly against the flaredcntry end 16a of hole 16 as will be understood from an inspection of FIG. 2.

The screws 15 for securing vice sections 11, 12, 13 in assernlbly are preferably of the so-called Allen type with squared sockets in their head ends so as to be operated by the squared end 27a of the Allen wrench 27 shown in FIG. 4. A storage recess 46 (see FIG. 1) is provided in one end of vice section 10 for the handle end of the Wrench 27, the laterally turned end thereof being engaged by a clip 43 which is secured as at 44 to the end of the section 11 so as to retain the Wrench in its storing recess.

From the foregoing it will be apparent that the vice 10 will take twenty differently threaded studs and ten difierent sizes of studs and tubes. flaring, it should be noted that this can be accomplished without beveling the entry ends of holes as at 20a etc., although such beveling is preferable.

The yoke-form carrier 34 for the tube end beveler can be readily slid into and out of the opposite side-provided grooves 42; and when located therein can be readily adjusted to align the head 38 with a tube end to be flared.

Having thus described my invention, what I claim is:
