SAMUEL .T. Tom), on DETROIT, MICHIGAN, lassIonon or ONE-HALF To JONATHAN v PALMER, .13., or DETROIT, MICHIGAN.
WORK-HOLDER FOR MILLING-MACHINES.
Specification of Letters latent.
Patented Mar. is, rare.
Application filed May 7, 1917. Serial No. 166,812.
To all it may concern:
Be it miown that I, SAMUEL J. Tom), a
citizen of the United States of America, residing at Detroit. in the county of Wayne Patent No. 1,138,515, granted May 4, 1915,
and Patent No. 1,213,300, granted Jan. 23,
1917, both pf these patents disclosing novel work holders-for milling machines.
The present invention aims to provide work holders. that may be easily and automatically articulated so as to prevent shavir-gs, cuttings, and the millings of a machine from falling on to the shears thereof and 'rinding or cutting the shears besides retar ing the progress of the work holders or requiring more power to feed the same.
My invention further aims to provide means for connecting the work holders or tables of a milling machineso that the work holders maybe fed to the machine and removed therefrom, without disturbing those work holders that are inactive position.
My invention will be hereinafter specificallydescribed and then claimed, and refer ence will now be had to the drawing, where- Figure 1 is a longtitudinal sectional view of the workholders in connection with a milling machine;
' ig. 2 is a cross sectional-view taken on the line IIII of Fig. 1;
Fig. 3 is a perspective view of a detached workholder;
Fig. A is an enlarged longitudinal sectional view of portions of connected workholders.
In the drawings, 1 denotes a pair of.
shaft is adapted to be driven from the same source of power as that employed for operating the milling machine.
Each workholder has the ends thereof beveled, as at 10 and 11, so that the forward beveled end of a workholder may abut the rear beveled end 11 of another workholder, and it is essential that the rear ends of the workholders overhang the shears 1, that is,
by being undercut or under beveled so as toprotect or shield the shears 1 from shavings or millings of the machine.
To connect the workholders 3 and I, the
forward beveled' ends of the workholders 3 are provided with sets of depending enlargements, each having a stepped vertically disposed opening 13 with the lower end thereof closed by a detachable plug 14. In each stepped opening 13 is a pin 15 having a head 16 in the large part of the opening 13. Between the head 16 and the plug 14- is a coiled compression spring 17 holding the end of the pin 16 protruding normally from the beveled face 10 of the workholder. The pin 15 has the end thereof beveled, as at 18, so that it may readily ride against the beveled face 11 of a preceding workholder and enter a recess 19 provided therefor in the beveled face 11.
By simply pushing the workholder 3 toward the workholder 4, the pins 15 of the workholder 3 will snap into the recesses 19 of the workholder 4 and as the workholder 4: may be in. engagement with the worm 6 to be fed through the milling machine, the workholder 3 will be drawn thereby on the shears 1 of the machine. After the Workholder 4' passes through the milling machine it may be bodily elevated and in this manner disconnected relative to the workholder without disturbing the feeding operation bf the same.
The very fact that the beveled faces 10 of the workholders overhang the shears of the machine prevents shavings and Inillings from being deposited thereon, and what shavings or millings do accumulate upon the shears are removed to a certain extent by the beveled faces 10 of the Workholders.
It is thought that the operation and utility of the workholder will be apparent without further description, and while in the drawing there is illustrated a preferred embodiment of my invention, it is to be understood that the structural elements are susceptibie to such variations and modifications as fall within the scope of the appended claims.
What I claim is 1. In a milling machine having shears and a feeding mechanism, workholders slidable on the shears of the milling machine, said 'workl'iolders having the ends thereof provided with beveled faces and the beveled faces at the rear ends of the workholders overhanging the shears of the milling machine, and means at the forward ends of the workholders protruding from the beveled faces thereof adapted to automatically said-workholders having beveled faces for abutting relation, and a spring pressed pin protruding from the beveled face of oneflfi workholder and adapted to engage in the beveled face of an adjoining workholder.
In testimony whereof I afiix my signature in the presence of-two witnesses.
