Be in known that. I3. Gian-urns E5. Tine Mm, a citizen of the United, States. oli residing at; Betro-it; in; the county 5. ofWliayne and. States of Michigan, have: in.- vcented certain new and useful: Improve.-
ments: in Machines-v fon Straightening Drills or the like; of. which the fbllowing is a:
specification-,. reference being hath therein to 1-10; the accompanying. duel-wings.
The invention relates to machines for. straightening cylindrical? artinles and; partienlarly to machines designed for straighteni-ng drills or the like; @ne object of themventioir is in providea oonstruetioninwhich sized dr'illson'tihe like; @then objects of: the
inaiention reside im the novel: anrangements. and combinations of pants as more fulily hereinafterset. fontlr.
In; the drawings:
- Figure 1' is a. perspectiveview oh the cons stiuuotion; embodyingimy inventions;
Fig-2. 2. is aventicali cross section there- :is through Fig. 3* is a; front elevation of: as portions of} the: rollers with a: drill therebetweeni;
Fig. 4-. is a vertical; cnossseotion; thnoun h a portion Of. the? machine.- on. the unis of the lower'noller.
1 and 2 are respectively upper and lower rollers mounted in a suitable frame 4 and 5 are gears upon opposite ends of the respective rollers l and 2 and preferably outside the end standards 6 of the frame. 7 are pinions mounted upon opposite ends of the shaft 8 and meshing with the gears 4c and 5, the shaft 8 being driven by means of the belt Wheels 9 upon its outer ends.
The driving arrangement is such that the rollers 1 and 2 are rotated in the opposite direction and at the same angular speed.
10 is a table pivotally mounted at the front side of the frame 3 and movable toward and away from the space between the 1919i Serial Nb- $68,580:
rollers) 12 andz' 2: for the purpose of: inserting the drill IL or; the like.
12,: which. latter is..rotatably mounted; upon the frame: 1-37 are rook arms nonrrotatar bliy. securedi' tothe: shaft 1J2 and extending:
laterally outward from the frame, these rock; arins being pivotally secured. tow the rods 14% which. extend! downward adjacent to. the bottom: of? the frame and; carry a. suitable foot-operating. member 15 116 are linhspivotal'ly eonneeteditothe frame 3 and.
to the lower ends of." the rods 1%- to( limit the inward.- movement of the lower ends of the-rods 1A.. 'Ehe arrangement of parts. is such that? the-inner endz ofi'the table 1.0 nor.=
ma-lly extends into the space between. the
rollers 1: and 2' and is. adapted to move the drill or the: like 11? int operative relation witlr the rollers. By moving the footoperating member 1 5 downwaid the. tabl'e can: berocked outwardly. This table is preferably provided with; the projection 1-=T- uponits upper surface for holding the drill orthe like: thereon after disengagement from between. the rollers.
18 isair abutment or stop. mounted upon.
thestandardsfi and extendinginto the space between the rollers 1 and- 2" a distancev such that the axis-of the d rill-or'the lil'ie LL when inserted between tihe= rollers oan be in sub: stantially the plane of the axes: of the-rollierss This step or abutment prevents the drill or-the like from being forced? through th'e'space between therollersbythe table 1.0.
To-zwoid t lie necessity of: stopping the machine to remove the straightened drill; or the like from between the rollers, the lower roller 2 is mounted to slide vertically up-and downin the standards 62 Fon this purpose it is mounted at its opposite ends in bearing blocks 19 beneath which extends suitable levers or rock arms 20 which are pivoted at one end 21 upon the standards 6. The free ends of these rock arms 22 have projections 23 extending into thepaths of the cams 24C. The latter are driven in time relation to the rollers 1 and 2 but at slower speed, and as shown are mounted upon the shaft 2') at the rear of the standards 1. Non-rotatably mounted upon this shaft are the gears 26 which are driven from the lower roller 2 by means of the pinions 27 mounted upon the lower roller and the intermediate gears 28 rotatably mounted upon the standards 6.
4 As. shown, this table. is nonerotatably mounted. upon; shaft.-
The arrangement of parts is such that after the drill or the like 11 has been operated upon by the rollers for a predetermined length of time the low portion 29 of each cam 24 comes into registration with the projection 23 upon each rock arm or lever 20 and allows the latter to swing downwardly, which permits the bearings 19 carrying the lower roller 2 to move downward by gravity. This automatically releases the pressure on the drill or the like and allows the latter to slide from between the rollers l and 2 and upon the table 10, when the latter has been lowered. The depths of the teeth of the pinions 27 and gears 28 are sufficient to permit of this movement of the roller.
For the purpose of adjusting the machine to provide for different sizes of drills or the like the following construction is provided:
The upper roller 1 is mounted at its opposite ends in bearing blocks 30 which are vertically adjustably secured in the standards 6 as by means of the rods 31 secured to the bearing blocks and threadedly engaging the standards. For the purpose of simultaneously adjusting these rods they are provided at their upper ends with suitable gears 32 which are adapted to be rotated from the shaft 33 extending between the standards 1. The shaft 33 is rotated from the hand wheel 34 which is mounted upon the cross bar 35 extending between the standard 6.
For maintainingthe pinions 7 in driving; relation to the pinions l and 5 upon the rollers the arms 36 and 37 are provided extending respectively from the upper bearingblocks 30 and the lower bearing blocks 19 to the bearings 38 carrying the shaft 8. By this arrangement when either of the rollers are vertically moved the arms connected to the hearing blocks of the roller moved will move the bearings 38 to maintain the pinions 7 in driving relation with the gears of the rollers.
To maintain the belts 38 driving the belt wheels 9 sufficiently tight, the idler pulleys 40 are provided which yieldably rest against the belts.
The abutment or stop 18 can be adjusted both vertically and horizontally and as shown, is mounted upon brackets 41 which are secured to the standards 6 and can be adjusted vertically and horizontally to a limited extent. In the present instance the brackets have holes of greater diameter than that of the bolts extending therethrough and ment. Also means is provided for automatically moving one roller toward and away from the other roller to permit of ready insertion of the drill or the like. Furthermore, the machine is adjustable to permit the same machine to operate upon drills or the like of different sizes.
What I claim as my invention is:
1. In a straightening machine, the combination with a roller, of a cooperating roller spaced therefrom, said rollers adapted to engage a substantially cylindrical member therebetween with its axis substantially parallel to the axes of the rollers, means for rotating said rollers in the same angular direction, means for simultaneously adj usting' the opposite ends of one of said rollers and means for automatically moving the other of said rollers toward the adjustably mounted roller. Y 2. In a straightening machine, the combination with a pair of cooperating rollers spaced from each other for receiving a substantially cylindrical member therebetween with its axis substantially parallel to the axes of the rollers, of means for rotating said rollers in the same angular direction, adjustable bearing blocks rotatably carrying one of said rollers, means for simultaneously adjusting said bearing blocks, bearing blocks rotatably carrying the other of said rollers and means for actuating said last-mentioned bearing blocks to move the roller carried thereby toward the other roller.
In testimony whereof I affix my signature.
