MACHINE FOR TURNING HANDLES.

SPECIFICATION forming part of Letters Patent No. 481,875, dated August 30, 1892.

Application filed August 10, 1891. Serial No. 402,313. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM D. SNYDER, of Wetzell, State of Michigan, have invented certain new and useful Improvements in Machines for Turning Handles; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which Figure l is a top plan view of myimpro'ved cutting-head for handle-turning machines. Fig. 2 is a face view thereof. Fig. 3 is a transverse sectional view 011 line x 00, Fig. 1. Fig. i isa longitudinal sectional View on line 00 ac, Fig. 2. Figs. 5 and 6 are detail views.

This invention is an improvement in cutting-heads for handle-making machines or lathes wherein the handles are cut by revolving knives from rough stock, and it is also an improvement upon the handle-machine for which Letters Patent of the United States were issued to me on the 21st day of July, 1891.

The object of this invention is to shorten the distance between the cutters and journal-bearings of the revolving arbor which supports the knives and to improve the construction of the finishing-knives support, all of which will be clearly understood from the following description and summarized in the claims.

Referring to the drawings by letters, A designates a tubular revoluble arbor mounted in proper journal-bearings on a suitable supporting-frame, and on its projecting end are fixed two similar proximate disks B b, the former being at the outer end of the arbor and the latter near the outer bearing, and O is a short sleeve fitted on the arbor and adjoining disk 5 and forming one of the journal-bearings of the arbor. The disks B b are united rigidly by transverse bolts D D, which are shouldered at their ends, so as to hold the disks properly separated.

E E designate finishing-knife holders, consisting of blocks suspended by straps or eyes e e on bolts D between the disks B b, so that the blocks can oscillate on the bolts. Two

blocks are shown arranged diametrically 0pposite to each other, and the finishing-knives F F are adjustably attached to the inner ends thereof, substantially as shown, and are equipoised or counterbalanced by weighting the outer ends of the holders, as indicated atf.

G G are adjustable gibs secured to the inner ends of the holders opposite the knives and having inclined grooves g in their faces adjoining the arbor, which grooves are ongaged by inclined tongues h on sliding rods H, resting in longitudinal grooves a a in arbor A, which grooves and rods extend under disk I) and sleeve 0, as shown by dotted lines in Figs. 1 and 4, to a clutch-collar I, loosely mounted on the arbor between its bearings, but connected by pins z' z' to the ends of rods H, so that by shifting the collar on the arbor the rods will be shifted, and by reason of the engagementofinclined tongues h with grooves g will oscillate the knife-holders E, so as to throw the knives F toward or from the axial line of the arbor, thereby regulating the cut of the knives. The collar can be shifted by a bifurcated pivoted lever J or in other suitable manner, so as to control the position of the knives, as usual. The edges of the finishing-knives project more or less into the arbor through openings at therein adjoining the inner ends of the holders between disks B b, as shown.

7' is a sheave-pulley fixed on the arbor and by which motion is imparted thereto by belting. It will be observed that the sliding rods 11 H pass under the sleeve-bearing C of the arbor and the collar is placed between the bearings instead of outside the same, thus enabling me to shorten the arbor or at least bring the cutting-knives nearer the outer journal-bearing and rendering the arbor more steady in operation.

In the end of arbor adjoining disk B is a blank guide K, which is a metal ring screwed into the end of arbor and havinga flaring conical mouth tapering to a bore of the desired size to guide the work into the arbor between the finishing-knives. This guide is removable and can be replaced by others of different sizes, according to the work to be produced.

L L designate the gouging-knife holders, (two being shown,) mounted on the outer face of disk B diametrically opposite to each other.

They consist of a base-plate M, pivoted by a bolt m to the face of disk B, and adjustably secured by means of a bolt N, passing through a slot at in the plate M and tapped into disk B. From plates M spring outwardly-inclined slotted studs 0 0, through which pass the roughing-knivesl Z, which are retained by setscrews 0. The edges of the gouging-knives are held diagonal to the length of the blank, thus increasing their effectiveness, and the holders can be adjusted to different angles to the blank, being cut so as to secure the best Working position for the knives. B y this construction the parts are strongly and compactly assembled, the arbor shortened, and the finishing-knives and their holders better protected, and there is less danger to the workman than in the machine already patented to me.

Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent, is

1. The combination of the revoluble tubular arbor having openings near one end for the introduction of finishing-knives and the disks fixed on the arbor at the ends of said openings, with the oscillating equipoised finishing-knife holders pivotally suspended between the disks, and means for adjusting said holders, substantially as described.

2. The combination of the tubular arbor, the opposed fixed disks thereon, the bolts uniting said disks, and the finishing-knife holders suspended between the disks and revolved therewith, with the finishing-knives and grooved gibs mounted on said holders and the sliding rods moving in guide-slots in the arbor and extending through one journalbearing thereof, having inclined tongues engaging said gibs for adjusting the holders, all substantially as and for the purpose set forth.

3. The combination of the revoluble tubular arbor having openings near one end for the introduction of finishing-knives and longitudinal grooves, with the knife-holders pivotally supported on and revolved by the arbor, and the sliding rods lying in and protected by the grooves of the arbor, extending through one journal-bearing thereof and engaging the inner ends of the holders, and means for shifting said rods, substantially as specified.

4:. The combination of the tubular arbor having openings and grooves, substantially as described, the disks secured thereto, the knife-holders pivotally mounted between the disks, the groove gibs on the inner ends thereof, the movable rods lying in the grooves of the arbor, extending through one of the journahbearings of the arbor and having inclined tongues engaging the gibs, and the de- Vices for shifting said rods, substantially as described.

5. The combination of the tubular arbor, the opposed disks fixed thereon, the bolts uniting said disks, and the adjustable opposite oscillating equipoised finishing-knife holders suspended between the disks and revolved therewith, and means for simultaneously adjusting said holders, and the independentlyadjustable gouging-knife holders L, attached to the outer disk, substantially as set forth.

6. The combination of the revoluble tnbular arbor having openings near one end for the introduction of finishing-knives and 1ongitudinal grooves, and a journal-sleeve thereon near said openings, with the knife-holders pivotally supported on the arbor, and the sliding rods lying in the grooves of the arbor, passing through said sleeve and engaging the inner ends of the holders, means for shifting said rods, and the blank guide in the end of the arbor, substantially as described.

7. The combination of the tubular arbor having openings and grooves, substantially as described, the disks secured thereto,-the knife-holders pivotally mounted between the disks, the grooved gibs on the inner ends thereof, the movable rods lyingin the grooves of the arbor and having inclined tongues engaging the gibs, and the devices for shifting said rods, and the journal-sleeve slipped over the arbor and rods and adjoining the inner disk, substantially as specified.

8. The combination of the tubular arbor, the opposed disks fixed thereon, the bolts uniting said disks, and the oscillating equipoised finishing-knifeholderssuspended onsaid bolts between the disks and revoluble therewith, the gouging-knife holders attached to the outer disk, and the blank guide in the end of the arbor, with the grooved gibs 011 said holder, the movable rods extending through one journal bearing of the arbor, having inclined tongues engaging said gibs, and the devices for shifting said rods, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

WILLIAM D. SNYDER.
