r 5 Claims. 1

- Generically, the present invention relates to a machine for assembling or matching a plurality of flat articles of similar internal contour into stacked or face to face relationship, and specifically, has reference to assembling a plurality of key blanks having either a male or female keyway in the internal diameter thereof in such a manner that the blanks will be in perfect alinement. It will, of course, be appreciated thatit has been ratherv difiicult to assemble articles of the above mentioned nature, and it has generally been necessary to match the blanks by manual processes which are tedious, time-consuming and expensive. Devices have been provided for assembling disk-like members by mechanical means, but to the best of my knowledge, no set machine has been developed for arranging key blanks having a keyway on the inside diameter in proper alinement.

Accordingly, an important object of my invention is to provide a machine wherein a plurality of key blanks are disposed around a rotating spindle which cooperates with a support therefor, in such a manner that the spindle will pick up the keyway of the respective blanks whereby the blanks will be correctly and perfectly alined.

Another object of my invention is to provide a machine for alining a-plurality f blanks wherein the machine includes a plurality of alining members which are operated in unison, thereby permitting a plurality of blanks having different types of internal contours to be matched during a single operation. r a

Yet a further object of my invention is to provide a machine for matching or alining key blanks of the type having a keyway in the internal diameter of the blanks which is comparatively simple in structural detail, positive and efiicient in operation, and capable of being inexpensively manufactured. I

And another object of my invention is to provide a machine of the character described wherein the supporting member for the rotatable spindle is so formed as to center the keyway of the blank upon the rotating spindle.

Broadly, the invention comprises a standard in which a spindle is rotata'bly mounted, the spindle being provided with a support, so constructed that the keyway of each of the blanks carried by the spindle and support will be centered so that the rotatable spindle can pick up the keyway of the respective blanks, thereby provid- In order to increase the capacity of the machine, a plurality of spindles and supports may be carried by the standard and in this situation all of the spindles are coupled by a suitable drive connection between the spindles and the source of power so that simultaneous movement may be imparted to the spindles. By thus providing a plurality of spindles it is possible to match or aline a series of blanks having different internal contours.

With the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application, wherein like characters denote corresponding parts in the several views, and in which Figure 1 is a plan view of the machine-constructed in accordance with my invention.

Figure 2 is a front elevational view of the machine shown in Figure l. I

Figure 3 is a rear elevational view of the machine, but being on a slightly smaller scale than Figuresl and 2. I

Figure 4 is a sectional view taken along the line 44 of Figure 1, looking in the direction of the arrows and being on a slightly enlarged scale. p

Figure 5 is a side elevation, partly broken away. of the support for the rotatable spindle,

Figure 6 is an end view of the support 'shown in Figure 5.

Referring to Figures 1 and 2, I have shown a base or supporting member I0, preferablyof rectangular outline, having a vertical plate" ll secured thereto adjacent one end thereof by" welding or the like. A motor [2 for driving the machine is bolted to the base In, as at I3. I

A plurality of bearing housings M are attached to the plate H at equally spaced intervals adjacent to the upper end of the plate by cap screws l5. A ball bearing assembly I6 is disposed within each housing I4 and a pressure fitting i1 is carried by each housing for supplying alubricant to the bearing l8.- While I have shown four such bearing housings, it is to be understood that'a more or less number may be employed and in' view of the fact that each housing and its associated parts are identical instructure and operation, the description will be limited to but a single unit.

A's'pindle' I8 is providedwitha longitudinal bor I9 extending therethrough and is pressed into the bearing [6 at its inner end and formed with an enlarged' hea'd 20 atits" outer end." A drive pulley 2| is carried by the spindle l8 adjacent and secured thereto by a set, screw.21. It is thought apparent that the spindle'"l8 employed:

in connection with the remaining bearing hous- A spacer 26 is dis-.

ing will be of lesser length thanzthespindletabove r described, and, as shown inFigure:1,-the"pulleys 24 on the spindles are all in alinement.

A circular rod 28 is adapt i zt 2elitemljmrough;

the bore IQ of each spindle and is secured to. the

spindle by means of a screw 29tappedinto: an

opening formed in the head 20. .As clearly illustreated inf-Figures 1 and: 4, the circularrlrods 28 are ofsuch a length asx toaextendg a,- substantial distance beyondl the? outer face-of "the" vertical plate-1 I. The'freeendofgtherod;:that-.is to say that endextending/beyond the outer :faceof the plate l 4 has a support 30 I associated therewith. The: supports-3 (l is suitably Esecured at .itszinner endto the" plateE-J I; as. indicated. at; 3 I and. is formed -witharecess 32:-inits upper? areasin which the rod 28 is seated. The outer end of the support 30 is cut away. tot-form a shelf:33rhaving an'arcuate uppen sur-face34;"?With reference to Figure 4, :it can-be seenthat a: bearing 35:1orf-the outer end of -the rod 2 8 -:is carried :by. the shelf .33 so that the rod will be maintained in the recess 32; Aspe'rhaps best illustratedin Figure-6; ithe sides of the supportan arebeveledor-inclined, as indicated at 36, 1 and. as *Wl11' :later be: more-fully described; the purpose f these sides is to: :carry the keyway of the disk so that' the disk -will-be stopped inthe proper position.

A plurality of-idler pulleys 3! are lccated intermediate the pulleys" 24, and each of then-idler pulleys is carried by astud-38 secured to the plate l h as-shown at 39.'--='A spacer 40 is locatedbetween the'=pulley=hub and thesecuring-means 39: One

of the pulleys 31, preferably the'pul-ley most distantly' removed from the" drive pulley 2 I is securedr as shown -at' 4|; to one -end==of a-linl-42. The-opposite end of the linkis bolted to the plate I l, as shown at 43, and hence it can beseen that "this pulley will function as atightener' for endless belt u which extends" around the pulleys 2 l and idler pulleys 31, in the manner shownin Figure 3.'
