SCREW-FINISHING MACHINE.
Specification of Letters Patent.
Application tiled August 1c, 1906, Serial No. 330,797.
To all whom it may concern:
Be it known that. I, thmuNoEY XV. Howments in screw finishin presses and is espe-. cially adapted for finlshlng the threaded ends of screws of eye-glasses after said screws have been inserted in the lens or parts of its mounting.
The object 1s to finish the ends of the screwssubstantially flush with the adjacent face of the mounting by swaging or riveting the same under rotary ressure of a suitable tool without liability oi breaking the lens or overstraining the I mounting,
In the drawings-Figure 1 is a perspective view of my improved screw-finishingpress, parts thereof being shown in section. Fig. 2 is a vertical sectional view ofthe upper portion of the machine, showing the guides for the rotary spindle or shaft and its actuating rod. Fig.- 3 is an enlarged inverted end view .of the finishing tool. Fig. l is a sectional view taken of line L -l, Fig. 3, of-the lower end of the same tool. Fig. 5 is an enlarged sectional view of the upper end of the lens supporting post.
This screw finishing press comprises essentially a standard -1 having a suitable supporting base --2 adapted to be secured to any available sup ort, not shown, said standard being provi ed with laterally projecting arms -3- and 4' having apertures -5 and -(3 respectively for receiving and supporting a rotary spindle or shaft T and a lens rest or post bearin -8-.
'The arms -3-- are provided wit additional apertures -9- for receiving and guiding a, vertically movable rod 10- carrying at its upper end a yoke '11 which is secured to the reduced upper end of the shaft or spindle ---7--, as best seen in Fig. 2, so that the shaft -7- may be moved vertically by the vertical movement of the rod ----10 This latter movement is accomplished by means of a hand lever 12-- which is fulcr'umed at -13- to the standard -1-- and is providedwith a furcated arm -1-'.t engaging a pin -l5 on the lower end of the rod -10.
A spring l6' is interposed between the yoke 11- and upper arm 3' for the purpose of retracting the rod 10- and shaft -7 to their normal tip-position, the .60
downward movement of said shaft and" rodbeing 'eifected by the rearward movement of the lever -12- against the action of the spring 16. The lower end of'the shaft 7 is provided with a socket l7 in 66 which is secured a finishing tool -18,' by
means of a screw -19, as best seen in Fig. 1. V I
The lens supporting post '--8 has its lower end tapered and fitted in the tapering socket -6 in the lower arm l,- the upper end of said post projecting some distance above the arm and is also tapered, and has its top face formed with a concave socket 20- for receiving and supporting the head of the screw, while the opposite threaded and is being finished, thereby bringing the st 'ain wholly upon the screw without liability of unduly straining the ears of the mounting through which the screw is passed, '30
and also avoiding any liability of cracking the lens. The lower face of the finishing tool "1.8 is formed with intersecting grooves 21 of substantially the "same? depth, forming at their junctions compara" 35 tively sharp swaging ribs -22- disposed in planes intersecting each other atthe longitudinal centers of the groove.
In operation, rotary motion is transmitted from any availablesource of power to the shaft or spindle 7-- by a belt 23- pass ing over suitable ldlers 24: and a pulley .5- rigid on said spindle.
In operation, the head of the screw after being assembled 1n the mounting and lens 18 supported upon the concave bearing face --20- of the post 8 with its upper end protruding a slight distance through the ear of the mounting at the upper side, whereupon the lever l2 is rocked by hand rear- 10o wardly to force. the finishing tool -18' down against the adjacent end of the screw, the rotation of said tool causing the swaging ribs -22- to trim and finish the adjacent end of said screw substantially flush with the adjacent side of the mounting such finish taklng a convex form corresponding to the swaging ribs 22. As soon as the threaded Patented Dec. 20, 1910.
'ing through the intermediate and upper of end of the nut is finished in the manner ust 1 deseribed the pressure upon the hand lever -12 is'lrelieved and the shaft 7 and its Working tool 18 are returned to their 1 normal position by the spring (3 What I claim:
