WORKHOLDER non DIESTOCKS AND THE pr m Application filed January 9 My invention relates to improvements in work holders for die stocks and the like.
Briefly stated, the invention has for one of its primary objects to provide a novel and improved device of this kindwhich establishes a very effective bearing contact with the work to prevent rocking or shifting of the tool relative thereto. 7 An object of the present inventionis to provide a work holder which will have all of the advantages of the interchangeable bushings, such as are commonly used to engage the work at an axially spaced point from the dies or other Work engaging elements,-and which has an added advantage over such bushings in that no removal of parts is necessary when changing from one standard siZe. of work to another standard size.
A further and more specific object of the invention is to provide a workholder for die stocks and the like comprising a pairof opposed rotatable elements having corresponding edge recesses adapted to be brought into opposition with one another for engaging the different standard sizes of work with which the die stock or other tool will be used,the nature of the construction being such that the work engaging elements may remain secured to the tool at all times, thus obviating the likelihood of their being lost.
The invention also contemplates a work holder as set forth, which comprises a minimum number of very simple and durable parts of inexpensive construction,the device being easy to assemble, convenient to use and capable of ready application to standard die stocks and similar tools without substantial modification thereof.
The invention also resides in certain novel features of construction, combination and arrangement of the various parts, andin certain modes of operation, all of whichwill be readily understood and appreciated by those skilled in the art upon reference to the accompanying drawings in connection with the following descriptive matter.
The drawings illustrate what is now regarded as a preferred embodimentof the invention, but it is to be understood that the same is capable of other mechanical expresi930. i Serial a, 419, 33.
sions within the spirit and scope of'thes ubject matter claimed hereinafter; V
In the drawings, Figure-1 is a bottom perspective view illus trating the application of my inventionto a die stock; i
FigureEZ is a to I plan showing piece of pipe in cross section;
Figure 8' is a cross sectional view through one of the rolls of'Figs. l and 2; and
view ofthe device 7 Fig l" isa fragmentary side View of one oftlie spring bearing elements.
Referring "specifically to the drawings,
' wherein the same reference characters have been used to designate the same parts in'all views, numeral 10 denotes adie stock" which may oftlie usual or any preferred form having the customary work receiving open;- ing into which project the'chasers 20. The stock being provided, of course, with the conventional handle sockets 30. y
In the drawings it-will be notedthat-I have illustrated =1- preferred 'embodimentiof the invention whereina removable workholder 55 isshown having a neck portion 56 adapted .to be inserted into the neck portion 57 of the die'stock and securedtherein by means of a thumb screw 58-yextendirig through-the neck portionof-the die stock and adaptedto engage in a recess in the exterior holder. Y
The work-holder of Fig. 1 comprehen'dsa "flanged frame having bearings GO for'the pintles 61 of apair of opposed horizontally .portion of the-neck portion of the workjournalled rolls 62 whose peripherial sur- "facesEare provided with eutoutsflof arcual' form, as indicated at '63, to'overl ie the work 'recei vin'ghole 65 so: as to embrace thework to 'provide a bearing so that the die stock and work-holder assembly can be' rotated 'relativelyof the work in' the threading operation.'j v a H 1 T-he frame of the-work-holder .55 provided :with small cylindrical portions 67: l
'threaded'therethroughandcarrying a spring pressed bearing element :69 adapted-toente'r recesessZO -fQrmed in the ends of cylinders -62,-vjv;hereb%t0 tend-to hold the same in a set -position. .umera-l'7l' designates size ind-i 1 eating marks adjacent the respectively recess portions 63 of the cylinders.
The two adjacent cutouts 63 form, as will be clearly seen from Fig. 2, bearing surfaces for a pipe, which is to be cut or threaded. The work will be very effectively engaged and supported by the two rolls, the bearing surface being the whole length of a. chord of the circumference of the roll, as shown in Fig. 3. It will be manifest also that it will be a very simple matter to rotate each roll to eflec'tively support different sizes of standard work. The rolls being held in position by the spring actuated ball member 69.
Having thus describedmy invention, what I claim as new and desire to secure by Letters Patent is:
1. In a pipe guide for pipe working tools, the combination of a frame, a pair of cylinders mounted'therein on opposite sides of the pipe axis and on axes parallel with each other and transverse of the pipe axis, each cylinder having a plurality of notches in its periphery, the notches in each cylinder being of different depth and each of them having curved edges whereby cooperating notchesmay define different pipe receiving openings. 7
2. A self-contained pipe guide adapted for removable mounting on a die stock, comprising a framehaving a neck to telescope with the die stock, and an open border, a pair of rollers ,journalled in said border on axes transverse to the die stock axis, said rollers flange on axes which are transverse to the pipe opening, each roller having notches at varying depths in its periphery, and means carried by the flange for engaging the rollers and retaining each of them in any of a plurality of selected positions.
In testimony whereof I aflix my signature.
BRADFORD T. BORDEN,
having a'series of peripheral notches of different depth. 7
3. The combination with a die stock havingan annular frame and cutters, ofa Work holder atone end of the die stock having a rectangular border frame with. walls extending in the general direction of the length of the. pipe'to be threaded, a pair of rollers mounted on parallel transverse axes on opposite sides of the pipe axis,'said rollers being j ournalled in theopposite walls of the frame and lying partly in the space between the frame walls, said rollers having formed in them notches of varying depth with their I bottoms forming chords of the circular contour of the roller.
4. A workholder for die stocks, comprising a frame having an opening for the passage of a pipe and a pro ecting flange 1n the form of an open quadrangle, and a pair of rollers mounted between the oppositesides of said'flange and journalled on axes which are transverse to the pipe opening, said rollers having'notches at varying depths in their eri heries. I
5. A work holder for die stocks, comprising a framehaving an opening for the passage of a pipe and a projecting flange in the form of an open quadrangle, a pair of rollers between the opposite sides of said flange rotatably carried by pins mounted in the
