This invention relatesto new and useful improvements in attachments for pivot polishers. v
The object of the invention is to provide an attachment for lapping or polishing which may be minutely adjusted, laterally as well as vertically.
Another object of the invention is to. provide means for rocking the tool spindle for burnishing or grinding the pivot.
A still further object is to provide a longitudinally movable tool spindle in combination with a belt hanger adjustable to posi tion as spindle;
An important object of the invention is to provide a supporting bracket and shank arranged for giving the proper vertical and horizontal adjustment onthe slide rest.
A construction designed to carry out the invention will. be hereinafter described. together with other featuresof the invention.
The invention will be more readily understood from a reading ofthe following specification and by referenceto-the accompanying drawings, in which an' example of the invention is showmandwherein: Fig. 1 1s a partial side elevation ofa ewclers lathe and slide rest equipped with an attachment constructed, in accordance with my invention, I F 2 is a plan view of thesame, I
Fig. 3 is a side view of, thebelt hanger-r tightener, I v Fig. 4 is a sectional viewof the 'jpulley mounting, i i V Fig. 5 is a perspectiveview of one'of the pulley retainers, t" i Fig. 6 is an enlarged sectional view taken on the line 66 ofFig. 2, 1
Fig. 7 is an enlarged sectional View ontlie line 7-4 of Fig. 2," V
Fig. 8 is an enlarged sectional view on the line 88 ofFig. 2, p
Fig. 9 is an enlarged sectional view on the line 99 of Fig. 2, I
Fig. 10 is a plan view of the lock washer for the post adjusting screw,
Fig. 11 is a detail of thelower end of the said screw, and Y Fig. 12 is a sectional view of the rocker spring and parts.
In the drawings thenumeral 10 designates a suitable slide rest which may be of any suil'able'design, either as. shown in the said drawings or as is shown in my co-pending application filed of evendate herewith. The slide rest includes a stud 11 in which a slide bar 12 is confined by a set screw 13. The stud is rotatably adjustable and its'supports are horizontallyadjustable. The bar 12 is horizontally adjustable. I
A right angular hanger 14 depends from the end of the bar; The enlarged circular base 15 of an uprighttubular'post 16 is fastened on the horizontal member of the hanger, by means ofscrews 17 (Fig; Concentrically within-the bore ofthe post and its base is mounted a vertical adjusting screw 18 which is threaded and has a groove 19 (Fig. 11) around its lowerend forrecarving a lock washer 20 (Fig. 10). "The screw is centered in the bore ofthe pbstby' engagingin an opening'21 (Figs. 6 and 7) m the hanger 14, while the washer 20 rests upon the hanger and is confined by the base 15. Theboreoi thepostreceivesthe tubular isthreaded to receive the screw 18.
The lapping attachment is an important part of the device. The tubular shank 22 has fixed to its upper end a right angular brackets'f23 from which a pair'of pilot pins 1 24'depend. Thesepins engage in wells. 25
tical movementw The screw 18 has a turning button26 on its upper end. For fastening ,1 thefshankin adjusted positions I provide a set screw 27 threaded through the post 16130 I engagethe shank and havinga jamhnut 28 for-lockingthe screw. g A horizontal arm 29 extends from the bracket 23 at right angles thereto, and its outerportion forms one side-of a rectangular frame 30. Between the frame members and parallel to the arm a rocker31'is pivoted. The rocker has ayoke handle 32 overhangmg said arm. The rocker (Fig. 9) 1S 'U-shaped and hasa sleeve bearing 33 at its rear end anda sleeve bearing 34 at its'front end. A spindle 35 rotatable in thesleeve is free to slide longitudinally A handle 36 (Fig. 2) is confined on the rear end ofthe spindle. Theforward end ofathe spindle is reduced so that a lapping tool 37'may be frictionally engaged thereon.
The front sleeve 34is disposed between standards 38 fixed on theframe 30 and rocks 1 between stop screws 39. (Fig.8) threaded through said standards. amb nuts 40 are mounted on the screws for'holding them in adjusted positions. A curved tension spring 41 (Figs. 9 and 12) is fastened on the frame and engages the rear sleeve 33. This spring will act to swing the rocker and hold the sleeve 33 in contact with one'of the screws 89. The swing of the rocker is limited by the spacing of the screws and when the handle 32 is depressed and released the spring will. swing the rocker to its normal position;
On the shaft a small pulley 42 is fastened and is driven by an endless belt 43 one end of which passes around said-pulley. This belt passes over a pair of idler pulleys 44 and is driven from the usual counter shaft (not shown). The pulleys 44 are mounted on trunnions 45 (Fig. 4) projecting from each side of a hub 46 carried by a hanger 47 which is centrally pivoted on a bracket 48. The bracket is slidably mounted one. square vertical staff 49. The bracket has a horizontal set screw 50 threaded therein and engaging the staff and carrying a jamb nut 51. The staff is graduated and the bracketxis fastened at different elevations by the parts 50 and 51. The hanger has a longitudinal set screw 52 and a jamb locking nut 53, whereby the hanger and pulleys. 44 may be adjusted in a vertical.
plane and fastened. in order to confine the pulleys 44 on the trunnions 45 l employ flanged collars 54 (Fig. 5) slotted at 55 to receive a pin 56 passing through (Fig. 4) the trunnion. v As isshown in Fig. 2 the lapping attachment is mounted so that the tool 37.-is inposition to act on the pivot which latter is setup in the lathe parallel to theface of the tool will be either parallel with, below or above the longitudinal axis of thepivotsthe screw 2'? is leosenedr and the screw 18 is turned by the button 26. If it is desired to hold the lapping tool against the vworker spaced therefrom the hanger 47 is swung, whereby the pulley 42 and spindle 35 will be shifted. The bracket 48 permits various adjustments of the belt.
The stafi 49 is swiveled in the frame 30 and fastened by a screw 57 When the tool 37 and its spindle 35 are swung on an angle so that the belt 43 might be thrown off the pulleys 44, said screw 57 is loosened and the staff turned so that the pulleys 44 are alined with the counter shaft.
What I claim, is:
1. In a pivot polisher attachment, :1 post supporting bar, a tubular post fixed thereon, a spindle support having an interiorly threaded shankidisposed Within the bore of said post, a screw threaded through said shank to vertically adjust the same and retained in said bar against axial movement, a spindle carrying a polishing tool mounted uponthe spindle support, and driving means for the spindle carried by said support. V
2. In a pivot polisherattachment, a post supporting bar, a tubular post fixed thereon, a spindle support at one side of said post having an extend-ed arm carrying an interiorly threaded shank disposed within the bore of said post, a screw threaded througl'r said shank to vertieallyad ust the same and seated within the bar, against axial move ment, va spindle carrying a polishing tool mountedupon the spindle support and a staif upon said support carrying driving members :torthe spindle.
3. In a pivot polisher attachment, an angular hanger,,means for horizontally adjusting the same, a vertical tubular post fixed upon the horizontalbar of the hanger, a spindle frame carrying shank disposed in said tubular post, an elongated pin on said frame seated in a well in the postto prevent rotative movement of an int'eriorly threaded the shankwith respect to the tubular post, I
a screw retained in said bar against-axial movement and threaded through said shank with an operating means at the upper end of the screw, and a spindle carrying a polishing tool adjustably mounted upon said frame.
In testimony whereofl aflix my signature.
