ARBOR-PRESS.
SPECIFICATION'forming part of Letters Patent No. 527,731,'dated October 16, 1894. Application inea' January s, 1894. sannita-196.003. (Nomade.)
To all whom, it may concern.-
Be it known that I, JAMESH. SHERIDAN, a citizen of the United States, residing at Fitchburg, in the county of Worcester, State of Mas'- sachusetts, have invented certain new and useful Improvements in Arbor-Presses, of which the following is a specification, reference being had therein to the accompanying drawings.
- This invention relates to certain new and useful improvements in arbor presses for driving mandrels and the like, and it has for its objects among others to provide a simple and cheap yet powerful press, of few parts, and having provision for the rapid return of the ram or hammer after it has performed its work.'
The machine embodies a screw ram or driver operated for pressure by worm gear and a worm shaft, and, for a quick return, by bevel gear which may be readily thrown into or out of operative connection, it being thrown out of operation when it is desired to actuate the ram to produce the required pressure, and by simple clutch mechanism thrown into operative position. A bed plate is fitted in a dovetail recess in the base and is provided with a plurality of holes of different sizes for arbors of different sizes.YY This plate is adjustable in its groove or recess in the base and is held by frictional engagement. The operative end of the ram is provided with a detachable face which is held to the end thereof by .a screw entering a groove in the end of the ram and balls are interposed between a shoulder on the ram and the upper end of the face.
Other objects and advantages ofthe invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claims.
The invention is'clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in Which- Figure 1 is a central vertical section through my improved press with portions in elevation. Fig. 2 is a cross section on the line 2--2 of Fig. 1, looking down. Fig. 3 is a top plan of the adjustable plate removed.
Like letters of reference indicate like parts throughout the several views.
Referring now to the details of the drawpreferably substantially circular in form and at its upper end provided with the lugs or ears a as seen in Fig. 1 to receive the uprights A which are passed therethrough as seen and provided upon vtheir lower ends with nuts ct bearing against the under sides of said lugs. This base is cast or otherwise provided with a central Vertical opening a2 as is shown in Fig. 1 and in the front is open to admitof a person putting in his hand to remove an arbor from the opening in the base. In the upper face of the base is a dovetail recess as seen inFigul in which istted to slide the plate B which is correspondingly beveled upon its edges as seen at b to t the dovetail recess. This plate is adjustable in this recess, being held in its adjusted positions lby friction. It has a plurality of dierent sized openings b as seen in Fig. 3 to take in different sized arbors, the openings being always central with the screw or ram soon to be described.
C is a vplate or yoke having the lugs c to receive the upper ends of the uprights A as seen in Figs. 1 and 2 and-which uprights are provided at their upper ends with the nuts c', the lugs of the yoke being held between these nuts a'nd the shoulders a3 on the uprights. This yoke is formed with a vertical portion C which has a lateral portion C2 which receives the hub d of the bevel gear D which is held therein as seen in Fig. 1, having a surrounding groove d in which works the pin d2 held in the said lateral portion, the outer end of which latter is enlarged to form a strong bearing for the gear, all as shown in Fig. 1. Above the lateral portion C2 the vertical extension is formed with a lateral portion 03 extending in the opposite direction to the portion C2 and forming a bearing for the ings by letter, A designates the base which shaft E which, at its inner end, carries a bevel gear E which meshes with the bevel gear D as shown in Fig. 1. The outer end of this shaft is provided with a shoulder or head e as seen in Fig. l and upon this shaft is slidingly mounted a hand wheel F which is prevented from displacement by this shoulder or cap. A clutch F of any suitable construction is provided so that this hand wheel may be made to revolve with lthe shaft or independent thereof. As seen in Fig. 1 the clutch IOO is disengaged so that the shaft will revolve independent of the hand-wheel. When it is desired to connect the wheel with the shaft the wheel is pushed inward until the clutch is engaged when the wheel and shaft will be united and revolve together. The gear wheel D is provided with a passage therethrough as seen in Fig. l and the screw rod or ram Gr is passed freely through this passage as seen xo in Fig. l, the rod being threaded its entire length and also provided with a longitudinal groove g as seen in Figs. l and 2 for a purpose which will soon appear.
On the upper face of the yoke C are the lugs or uprights I-I in which is journaled the worm shaft I carrying the worm I as seen best in Fig. 2, and provided at one end which is extended, with a liy wheel `Irl provided with a handle has seen in Fig. 2.
J is a worin gear mounted in'a central .opening in the yoke C and adapted to mesh with the worm I as shown in Figs. 1 and 2. It has 1a depending portion j which is iilledwith Babbitt metal as shown 4at j and the screwY rod is threaded through this metal asseenin l Fig. l, the nutand worm gear being mounted 1 for rotation but held Yagainst flongitudinal movement in any suitablemanner. The worm `on the wormshaftis provided at the end .with 3o ballbearing as seen 'at L7'2 in Fig. `2 to receive theend thrust.
Theigear D has a-key dtwhich fits in the spline'ofthescrew rodorram so that as it is `revolved it runs the the nut' ofthe wormgear.
The lower end of the ram or screw rod is `provided witha removable face or step G .as seen in Fig. 1, the end of the screw rod being reduced to forma shoulder g2, between which 4o `and theupper endof theface arearranged balls g3, the face beingiheld to the reduced end of the` screw rod by a small pointed screw L which` enters an annular groove l in the reduced end asshown in Figi. This allows 5 the-screw rod to revolve `on rthe `ballswhile the `face remains stationary.
With the parts constructed and arranged -substan tially as above specified the operation israsfollowsz-When it is desired to drive 5o the mandrel or` arbor the plate B is` adjusted to the size of thearbor, and i the .hand wheel Fismoved outward on itsshaftinto the position in which itis shown inFig. l so asy to disengage the clutch, and the wheel H .is turned to advance the screw rod or ram downward. When itis desired to move the. screw rod or rainupward after the arbor or inanscrew rod in or out ofj drel has been driven, the wheel F is moved inward on its shaft till the clutch is engaged motion to the bevel gear E and the gear D which moves the screw rod upward rapidly.
Modifications in detail may be resorted to without departing from the spirit of the in- I may employ a ball bearing for the thrust of the screw rod. I have shown such in Fig. l wherein M is a nut on a threaded extension j4 of the hub portion of the worm gear, and the upper face of this nut is provided with an -annular groove or recess m in which are located a train of balls fm. which rest upon a hardened steel plate M in the bottom of said groove or Vrecess in the nut and upon the yoke hardened steel plate N. As the tendency of the screw rod is to raise up with the end or `ring bearing against the under side of the yoke and the train ofballs. The wear upon the balls may be compensated for `by the adjustment ofthe nut M.
What I claim as new is- 1. The combination with a base, having ver- .tical opening and plate, of a yoke supported r`above and by the base, a worm shaft carrying a worm, a wormgearmeshing with, said worm, `and `a screw rod passed through the worm gear, in line with the opening in the base, as set forth. l
2. The combination with the base having vertical opening and the yoke supported thereon, of the wormgear mounted for rotationin the yoke andhaving a depending hub ,recessed `to receive .Babbitt metal, a screw rod `or ram threaded through said metal, in line `with and adapted to entersaid opening. means on the depending hub of `the worm l gear for takingend thrust` and means for operating the screw rod, as set forth.
3. Thecombinaton `with the yoke and the rworm gear with its depending portion having threaded extension, of the nut engaging the threaded extension andhaving an" annular groovea` plate between said nut and then n- -derside of` theyoke and` balls in the groove of the nut between the same and,` said plate, substantially as and for the purpose specified.
In `'testirnon y whereof Iaiiix my signature in presence of two witnesses.
JAMES Il.` SIIERIDAN.
