SPEGIF IGATION formingpart of Letters Patent No. 593,541, dated November 9, 1897.
Application filed March 10 1897.
To all whom it may concern.-
Be it known that I, IEvIN D. LENGEL, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Milling-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in milling-machines, and is intended more particularly for milling irregular surfaces.
The object of the invention is to produce a machine that will facilitate the milling of irregular surfaces and produce more accurate results than can be obtained by hand.
The invention is fully described in the following specification and clearly shown in the accompanying drawings, in which- Figure 1 is a plan view of my machine, showing a fork-crown, in dotted lines, in position to be operated upon. Fig. 2 is a vertical sectional view on line m m of Fig. 1, showing, in dotted lines, the position of the cutter. Fig. 3 is a longitudinal sectional view on line 'y 'y of Fig. 1, showing the fork-crown full, the gage being removed.
Reference-figures l, 2, 3, 4., and 5 are bear-. ings and are secured by means of bolts b to a base-plate or bench. In the bearings 1 and 2 is mounted the driving-spindle 6, to the end of which is secured the cutter 9. On this spindle is secured a belt-pulley 10, through which power is transmitted to the machine. A pinion 11 is also mounted on this spindle between the pulley and the bearing 2. This pinion meshes with a gear-wheel 12, mounted on a shaft 7, which shaft is in turn mounted in the bearings 3 and 4. Near the other end of this shaft it is formed with a pinion 13, and loosely mounted on said shaft between said pinion and the bearing 4 is a link 15, to the other end of which is mounted a gear-wheel 14. This Wheel is formed with a shaft and is rotatably mounted in said link. This shaft has a screw-threaded hole bored into its end, in which fits the body of the form 20. This form is made with a circular body, by means of which it is fastened to the shaft, its outer end 22 being made irregular in shape, it be- Berial No. 626,758. (No model.)
tened to the top of the link 15 and extends rearwardly over the top thereof and is provided with an adjustable weight 28.
The machine is intended to mill an irregular surface, and in the drawings herewith I have shown it adapted to mill the oval ends of a fork-crown for bicycles.
When it is desired to remove a piece of work from the machine, the link 15 is thrown forward, by means of the lever 27, around the center of the'shaft 7, on which it is mounted, giving free access to the face of the wheel and permitting of the easy removal and replacing of the work.
The fork-crown 30 is secured to the expansible bushing 28 on the face of the wheel 14, its end resting in the jaw of the gage 26, which gage is so set that the oval end of said forkcrown will be placed on the same center as the form 22 and preventing its rotation on said bushing. The link is then thrown forward again, the small end of the oval 22 of the form resting against the face of the wheel 23 and bringing the small end of the oval of the fork-crown against the face of the cutter 9. This cutter is of the same diameter as the wheel 23 and both are on the same center.
When the machine is started, the cutter will be rotated direct, it being secured to the end of the driving-spindle, and the train of gears ll, 12, and 13 will give rotation to the wheel 14c,which carries the fork-crown or other article to be operated upon, and which, being mounted in the link 15, will rise and fall as the irregular form 22 bears against the wheel 23, thus presenting the surface of the work to the cutter in the same irregularity as the surface of said form. Increased feed may be secured by adjusting the weight 28 on the lever 27 or by hand-pressure thereon. When the one end of the fork-crown has been milled, it is removed from the bushing 25 and reversed, bringing the other end in position to be operated upon. The guide-wheel 23 and the cutter 9 being of the same diameter and on the same center line it must naturalh follow that the piece operated on will, by reason of the loosely-mounted link to which it is fastened and which rises and falls as the irregular form bears against the guide-wheel, be milled to the exact shape as that of the form 22, as it will be presented to the cutting-surface of said cutter with the same irregularity as that of the form which regulates its rise and fall.
Other shapes can be milled on this machine and the manner of fastening and holding the work can be varied.
The machine can also be made double.that is, another cutter can be placed at the other end of the shaft 6 and the link and form with itsbearing can be duplicated. \Vith this construction every operation of the machinewill finish a complete fork-crown.
Inthedrawings-I- have shown a fork-crown; inposition to be operated upon, having the small end of one of the ovals bearing upon the cutter.
It is evident that on my improved: machine any irregular form can. be milled. All that is necessary is to insert a form of the shape desired in the shaft of the wheel M andthe work will be presented to the cutter in the same form.
of the invention; but What I claim is 1. In am-illing-m-achine, acutter-Q mounted on the driving-spindle, a train of gears for giving rotary motion to the work-carrying wheel 14, a linkloosely mounted on a shaft 7 and carrying said wheel 14, said wheel formed with a shaft which passes through and revolves in said link and, having an irregular form 20 mounted therein, an expansible bushing on the face of said wheel for securing the work itobe milled, a, gage for setting said work, a
guide-wheel against which the form bears,
! said wheel located on the same center as the cutter, the form causing the work-carrying wheel to rise and fall thus presenting an irregular surface of the work to the cutting-- surface of the cutter, substantially as set forth.
and carrying a gear-wheel 12andapinion 13 andhavin g a link 15 loosely mountedthereon,
'a Work-carrying wheel 14 mounted in said link, meshing. with said pinion 13', ad'apted1 to.
carry the'pieoe to be operated upon and having a shaft passing through and revolving in said link to the endof which shaft is secured a form, a bearing 5 in which is 'mounted a.
shaft 8 carrying a guide-wheel 23 on which the said form bears, and a weighted lever 27 secured to said link, all substantially as and for the purpose set forth.
In testimony whereof I afiix my signature in presence of two witnesses.
