DISK-HOLDER.
Specification of Letters luatent.
Patented Mar. 9, 1915.
, 'AppiicatiniedAprn28,1914. seria1N0.sa4,e24.
Be it known that I, JOHN MAKER, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Disk-Holders, of which the following is a specification.
lWIy invention relates to disk holders of the type employed inconnectionwith abrasive disks of small size, such for instance, as are used by dentists, my more particular purpose being to provide an efiicient mounting for the disk while the latter is subjected to rapid rotation.
My invention is particularly adapted for use in connection with dental engines, and provides means by which abradingv disks, provided with or carrying emery, garnet, sandpaper, cuttlesh bone, Crocus, Icarborun-V dum, or any similar substance, may be readily mounted upon and easily detached from a rotary spindle. a
By my invention, a disk of thekind just mentioned may be readily and conveniently mounted in position, and onel may be easily and quickly interchanged for another.
I further seek to produce a device of the character under discussion so arranged that the disk is rmly held in position upon the spindle until released bypressure applied for the purpose upon a release spring, and so that any unusual pressure brought to bear upon the disk while in use, as is often neces sary where the abrasive material carried by the disk consists of coarse grit, the disk cannot be pried loose.
It is a custom among dentists to avoid rotating a disk or stone so that the travel of the abrasive surface thereof is toward the gum of the patient. Thatv is to say, the abrasive must follow the grain rather than go against the grain. My device therefore, is well adapted for avoiding the dihculty of working against the grain of the gum.
Reference is made to the accompanying drawings forming a part ofvthis specification, and in which like letters indicate like parts. Y
Figure 1 is a side elevation of a mandrel stem or drill shank, equipped with one form Y of my invention. Fig.'2 is a vertical section through the same. Fig.l3 is an end elevation of the mandrel stem, the disk and fastenings therefor being removed. Fig. 4 is a detail view, showing in perspective the latch forming part of the fastening mechanism.
Fig. 5 is a section somewhat similar to Fig; '2, but showing a different form of the fastening mechanism and a different type of disk secured thereby. Fig. 6'is an end elevation of the mandrel stem shown in Fig. 5, the disk and fastening therefor beingy removed. Fig. 7 is a fragmentary plan, showingstill another type of disk, and parts carried by the same.
1A mandrel stem appears at 8,v and is provided with an enlarged portion 9, and with a head 10 of: substantially frusto-conical form, these parts, in this instance, being in- Y tegral. The head 10 carries three small lugs 11, each having the proximate form of a steepv pyramid. The enlarged portion 9 is provided with a'hole 12, the latter being flared slightlyv at 13. A cap'14 is provided centrally with a stem 15, the latter havingl a. reducedrportion 1G and a shoulder 18. @ne end of the stein 15 is provided with a dull point 17 to facilitate its entering the, A
A leaf spring 19 is mounted upon the enlarged portion 9 of the mandrel stem, and is held inposition by a rivet 19a. The spring 19 carries a bent portion 20 having the proximate form of a stirrup and pro- `vided -with a cross portion 21 which is `nearly straight.v
This portion ts into a slot 21a with which the enlarged portion 9 of themandrel stein is provided. i
` An abrasive disk is shown at 8a. In order to mount the disk in position, the stem'15 is thrust through a hole in the center of the disk and inserted in the hole 12. Pressure now being applied to the cap 14, the lugs 11 are thrust through the disk. The straight .portion 21 of the latch now 'lodges against the shoulder 18, so as to prevent the withdrawal of the stem 15 from the hole 12.
In the form shown in Figs. 5 and 6, the Y enlarged portion 9 is provided with a head 22 of substantially frusto-conical form, this head carrying a boss 23 having a substantially triangular form in cross section. The enlarged portion 9 is provided with a hole 21. A disk 25, which may be of carborundum or other hard substance, is provided with an opening mating the form of the boss23. In some instances I may use a disk 26 having a metallic center 27, the latter being kprovided withV a triangular opening 28. By this arrangement undue strain upon the abrasive material of the disk 26 is avoided. The opening 28 simply fits over the triangular boss 23. A pin 30, provided with a head 29, extends into the hole 24: and is secured by the latch, as above described With reference to Figs. l and 2.
The operation of my device will be readily understood from the foregoing descrip tion. The disk or its equivalent being mounted upon the mandrel stein, as illustiated anddescribed, the stem is mounted in a dentall engine, or at least connected with a fiexible shaft, and is caused to rotate. The disk is then applied to a tooth, a section kof bridge work, or other analogous object, and is directed by hand.
I do not limit myself to the precise construction shown, as variations may be made therein Without departing from the spirit of my invention. Neither do I limit myself to the use of disks made of any particular material.
Having thus described my invention, What I claim as new and desire to secure by Letters Patent is as follows:
l. In a disk holder, thecombination of a mandrel stein provided with an axially disposed opening and a 'transverse slot crossing said openingand merging therein, a
spring latch mounted on the mandrel stem,

vided With a portion extending through saidslot and partially into said opening, a disk engaging said mandrel stem, and a .fastening member engaging said disk and provided with a pin having a shoulder, said pin ex- Y tending into said opening so-that saidshoul.
der engages said lportion of said latch..
3. In a disk holder the combination of a mandrel provided With an axially disposed opening and a transverse slot .crossing said` opening and merging therein, a spring latch: mounted on said mandrel stem and providedI with a portion extending through saidslot f and partially intothe axial opening, a disk engaging said mandrel stem and a fastening member engaging said disk and provided for engagement by the latch When the pin is inserted in the axial opening.
4L. In a disk holder the combination of a mandrel stein having` 4an axially .disposed oljaeningand With a transverse slot :crossing said opening and merging therein, a .spring and a fastening member engaging said; diskand provided With a pin having a portion of its shank reduced and adapted to be engaged by the transverse portion of thespring latch.-
In testimony whereof I have signed myl name to thisspecification in the presence of tivo subscribing Witnesses.
