This invention relates to improvements in pipe vises and benders and, more particularly, to'improvements on the pipe vise and ldated Oct. 16, 1928.

The present improvements comprise avsaddleattachment which `may bek applied to, or removed from, the base of the appliance, and chains connected tothe base and adapted bender set forth -in my Patent N o. 1,688,199,

10 tobe made to encircle a' tree, telegraph or telephone pole, post, piece of studdingyor e other object, -whereby rthe pipe vise and bender may beL secured in position, ready for use'at the place where work is -to be done,

thus obviating the necessity of providing a benchfor the like, as has'been customary.v

When the object is cylindrical,ffor instance 'a telephoneor telegraph pole, the saddle is used but; when'the object is square,

the saddle may be detached 'from thebase of the pipe vise and bender and ,the base and chains used to hold' theappliance in position. `Otherimprovements reside in the provi- `sion ofacut-out part or-notch adjacent the` '25 seat forl thejfiXed jaw so that when itis 130'in`g'yoke which has an integral stubI or projection overwhich a section of pipe may be fitted for use as an operating handle; con` structing the ,bending form as a skeleton, to lighten the weight; and other improvements i which appear more fully hereinafter. l

` A practicalv embodiment ofthe invention 'which has` been found tojbe successful is yshown in the "accompanying drawings, in which: Y t

ance to be positioned most conveniently for f use. s v Y l s Holes i3 are provided in the" brackets and Vin a web of the form for the accommodation of the'necessary bolts or screws. t

Instead of providing a form which hasa complete web, the formis'substantially skeleton asshown at 41 and isprovided `with ribs 5 whichr provide the necessary strength, whereas the` skeleton form lightens the weight. y

VThe groove 6 in the `form is, for. the accommodation of the rod, pipe, tube, or conduit which is to be bent,andL said groove 'is laid out on a curve, as usual in pipe benders. VThe pipe bending lever comprises a yoke 7 which straddles the form and is pivoted on a removable pin 8, which passes through the hub of the form, suitable retaining' means prevent displacement ofthe pin. f The yoke has another pinflO'which' may beV removable,` or headed down at 11, saidV pin constituting an axle for the` grooved ls ection of pipe 14 which may be as long as desired and which willserve as `an operating PATENT OFFICE f r There is a movable head 23 which slides on, and is guided by, the legs ofthe yoke. A

the bracket, said fears and bracket having holes to accommodate a pin 16 by which the frame l18 has one' of its legs pivoted to the body, enabling the frame'andthe device car- -ried thereby to be swung aside as shown by dotted lines (Fig. 3).

The vise has a screw 20 threaded through its cross-piece and it is provided with pivoted handle 21, said handle being adapted to be turned crosswise ofthe screw and used as a lever forturning the screw, or, disposed inv extended. relation to the screw.

steel jaw 24 is removably connected to the V`.head by screw bolts 25, enabling steel jaws of other sizes to begsubstituted for the steel jaw 24, if desired.

VFor the purpose .of securely latching the free part `of the yoke without having to resort to the use of a locking pin, there is provided a hook or latch 35 Vwhich is pivloted tothe yoke 18 at 36 and is adaptedfto engage and lock with the sloping shoulder 37 on the body 4.

On releasing the hook 35 from the shoulder 37 the yoke 18 can be swung back, as shown in dotted lines, to permit. quick removal of thebent` or threaded pipe or the like.

latched, as shown in full lines.-

For the purposeV of securely clan'iping the pipe, the tube, or the like which is to be bent, threaded or cut off, l provide a stationary, but removable, steel jaw 30 (Fig. 9)

to match up with `the aw 24, said jaw being secured in line 'with jaw 24 by bo-lts` pass- `ing through holes 32 in the jaw 30 and holes `33 Vv(Fig. 6) in the body. This fastening, like that shownat 25 for the j aw 24, enables the jaw 3()` to be removed for replacement, re shaping, substitution, etc..

Y To enable a pipe or tube or conduit tobe bent closel to its end `and to accommodate a pipe coupling and section of pipe which llave'to be provided invsuch an' operation,

jI have'provided a semipircular cavity 39 at the inner endof the groove v(i in the bending form and a semi-circular notch 40 in the This cavity and 42 which are attached to the piece Qffpipe .43 which is.' to be bent-- y When it is necessary -tebendthelpipe-AS The yoke can then be quickly re Vholder or socket 34. Accommodation having thus been provided for the pipe coupling and pipe section', the end of the pipe 43 can be located in the end of the groove 6 so that the roller 12 can act clear down to the end of the pipe 43.

lVhen a bend is to be made in an intermed-iate part ofthe pipe' 43,-it is not necessary to use theA pipe coupling or extra section aforesaid but the pipe itself is directly gripped byithe

jaws

24 and 30.

ln any instance, however, where a bending operation is to be performed, the jaw 24 will be used to grip the pipe, or the coupling, `as the case may be.

Aflhould it be desired to use'the vise `by itself to hold a pipe, tube, conduit, or rod, for the purpose of cutting it on" or screw threading tions where a bench or horizontalsupportv is not available, the following improvements are provided.

A saddle 44 which hascurved, spaced seats 45 adapted toV lit thepole-.or`post, and has notched orbifurcated ends. y46, is detachably lsecured to the base. Y Preferably, the saddle has elongated slots 47 through "which pass bolts 48 extending through the lbase of the appliance. The bolts 48 enable the saddle to be adjusted lengthwise of the base so that the vise and the bending apparatus may be properlydisposed according to.y circumstances and enable the saddle to be "quickly attached or removed. f

To enable'the appliance to "be suspended prior to permanently fastening it on the pole or post, ahole 49 is provided inone of the seats 45fand through this hol'e 'there may be driven a nail 50 as shown in Figs. 1 land 8.

rlhe means' for fastening the vise 'and `ing a fhook 55 to engage any .desired link of ene of the chains, `and ahook boltlto engage any one ofthe linksof the remaining chain, said hook bolt having its 'screw threaded shank slidably mountedin the eye 57 and provided with a nut 58 by which it may be tightened or loosened.

Whenapplying the-pipe vise and bender to a square post, it may be directly connected thereto by screws or spikes driven through the holes 3, the saddle 44 being taken otf.

When the appliance is connected toa round post or pole, the saddle 44 is applied thereto, the nail 5() being driven through the hole 49 and into the .post or pole to suspend the appliance while the chains are being tightened. A link of one of the chains is then engaged with the'hook 55 and after the slack 'has been taken up, a linkof the other chain 5l is engaged withl the hook bolt. The nut 58 is then screwedup 'until the chains are tight around the pole or post.

What I claim is:

l. The combination'with a pipe, rod, conduit, or tube bender and vise having a base, of a saddle detachably connected to said base, enabling said saddle to be utilized or removed, separate chains each connected to the base and adapted to be passed around a pole or ,pos't, and an adjustable hook connector for detachably and adjustably connecting together the free parts of the chains.

2. The combination with a pipe, rod, conduit, or-tube bender and vise having a base,

Y of a saddle detachably connected to said base,

enabling said saddle to be utilized or removed, `separate ychains each connected to the base and adapted to' be passed around a pole I or post, an adjustable hook connector comprising a, bearing plate having an eye and provided with a hook adapted to engage a link of one of the chains, Vand an adjustable 'a hook bolt provided with a nut, the shank of the bolt being slidable through the eye and the hook of said bolt being engageable with a link of the remaining chain, said connector being adapted to detachably and adjustably connect together the chains around the pole or post.

3. In a pipe, rod, conduit, or tube bender and vise, the combination with a body having a bending form provided with a groove and with an enlarged cavity adapted to receive a pipe coupling on the pipe, rod, conduit, or tube to be bent, whereby the bend ma be made at the end of said pipe, etc., an also having a socket or receiver into which one side of said cavity opens, the opposite wall of the cavity being provided with a notch adapted to receive another pipe section connected to the coupling, means for clamping said pipe, etc., and meansffor bending said pipe, etc.
