STEADY-REST.

June 27, 1908.

- steady-rests fledl` March 23, 1908 'and Serial No. 422,805. "Itl "herefore follows that the present steady-res` possesses all the advantages and is capablezof all the uses set forth in the. parent' application.

In the drawings .l have shown in ,side elevation a steady-rest and its adjuncts comprising my invention, and referring to said drawing the numeral '2 denotes a slide which may be mounted for movement longitiidiiially of the bed or equivalent part of a metal-reducing or other machine with which said steady-rest may be employed. There may be cooperative with said slideZ means for holding the same in a desired adjusted position and for this purpose clampingnieans such as that denoted in l.a general tray' by 3 may be provided. rlhe slide 2 in turn supports a second slide as 4 the latter in practice moving transversely of the lower slide 3 and it may be operated by a mit on a screw as 5.- I have set forth in a brietl manner two slides which are found in certain known metal-reducing or grinding inachiiies. It is not' essential that I employ my steady-rest andits associated par-ts with said slides for I may use them, if desired,in other ways.

I have illustrated as rising from the upper slide 4 a standard or post 6 which constitutes a convenient supporting device for a lever as 7 shown as pivoted hy a pin 8 to said standard or post. Said lever 7 is represented equipped with a cam-portion as 9 constituting really the head of said lever and the purpose of which will be hereinafter set forth. It might be stated at this time, however, that the active face of the cani Sl'is exterior thereof and that such face is of progressively-incrtaising radius so that it can exert a powerful effect upon a steady-rest carrier as 1t).

Original application filed March 23, 1908, Serial No. 422,805.

Divided and. this application filed sei-iai No. 440,754.

shown consists of a blot-lc which is preferably bodily movable along a straight' path the latter being diagonal or at an angle to the work. (Illustrated by the dotted circle X.) .\s a means for guiding the steadyrest carrier lt), a pin or stud as 11 may be utilized, the said pin or stud being rigidly connected in some suitabh` way to the slide -land extending at an :ingle therefrom corresponding to that at which it is intended the carrier 10 should more durinnl its advance. The piu or stud 11 preferably extends through a perforation in the carrier or block l0. v

The steady-rest shown is designated by 1L and it is preferably removably -inounted upon the carrier therefor whereby it may be taken from place and one of a different character substituted therefor. The connection between the steady-rest and its carrier, however, is preferably a' rigid one.

The cani-lever is preferably automaticallyoperable and for this prurpose it.- is shown as provided on its long outer arm with an adjustable weiojht as 13 and which may be held in its dilierent adjusted positions by i screw as lltapped therethrough and adapted to engage said long outer arm, the weight being adapted to exert a constant. downward swing to or pull iipou said arni the. force thus developed beingjapplied to the cam 9 whereby the latter can advance the steadyrest carrier 10 and in addition-to this cani unyieldingly prevent reti-active movement' of said carrier by `virtue of which said steady-rest will be caused to not only follow up the Work as the grinding or other operation .progresses but will engage the work at` all times in a solid, substantial inafiner and eliminate all possibility of lateral movement of the work.

-The cam 9 preferably directly operates the cai'rier 10; by this lA do not mean that the cam necessarily has to directly engage the carrier but that its force is applied directly to the carrier or to some relatively rigid part thereof as the screw 15. This screw which constitutes a convenient adjustable stop is tapped tl'rough the carrier or block 1() and its inner end or tip is engaged by the active face of the cam t).l lt is clear that by the operation of the screw 'l5 the amount of advancing movement of the carrier 'l0 can be regulated. lhe advancing movement, of

constituting an Q' long arm moves downward the active face of the eain 9 will be caused to ride over the vsaid Screw to advance the carrier l0. The -fdilierenee between the point at which the i power is applied by the Cain 9 to the carrier 15.10 anll ll 3. axis er center of motion of said i," between said axis and vthe lever T so much greater than the distance place at which .the operatin force is applied to the lever 7 that lhiS alone would preventi unyiehlingly i barflnraril inovenienl. of Saill carrier.

alone' said work nml also lt will be apparent thai: the steady-rest l2 ,is rigidly but removably aiipijiorlteel by its -earrier ll). Haiil steady-rest so engages he work as lo permit the 0|.)eral-ion of a tool opposite Said {Steady-rest.

a; f i W'hal, l (claim is:

l. The combination of a Steady-rest ear rier having an adjustable stop, and' an ant0- inatieally-operative 'cani lever, the Caml of which is adapted to engage Said stop te advance said Carrier and unyieldingly preven' its relraetive movement.

2, rThe Combination of 'a bodilymovable steady-rest can'ier, a Screw tapped through the me, a cani for engaging Sail'l Screw, to nnyieldingly advance said Steady-rest ear rier, and a Second Screw' for limiting the movement of said carrier. A l

3. The combination of a bodily-movable steady-rest', carrier having an opening eX- Lenfling entirely through the saine from top to bottoni thereof, ay relatively-fixed guide pin extending entirely through Said opening the pin and opening' being at an. angle to the l vertical, anil a Cani for applying its ei'leet Clireetly to ,said carrier to unyieldingly aclvanee the saine. p
