Patented July 7, 1953 CENTERING DEVICE Walter E. Frisk, Chicago, Ill., assignor to Montgomery Ward & 00., Incorporated, Chicago, 111., a corporation of Illinois Application August 27, 1949, Serial No. 112,817

5 Claims. (91.33-191) 'This invention relates to acentering device for use in commercial establishments engaged in engraving a large amount of table cutlery.

Heretofore the procedure followed for engraving such cutlery by an engraving machine was for the operator, through his experience and skill, to approximate the centerline of the handle before applying the engraved design thereto. This procedure was time consumin and also resulted in a variance in the location of the design on the handle. The more elaborate the design, the more difficult it was for the, operator to correctly position the engraving.

Thus, it is one of the objects of this invention to provide a device which will enable the operator to quickly determine the centerline of the handle and thus expedite the engraving op" eration.

It is a further object of this invention to provide a device which is adapted to accommodate cutlery of various sizes and shapes.

It is a still further object of this invention to provide a device which is simple in construction, effective in operation, and inexpensive to produce.

Further and additional objects will appear from the description, accompanying drawings, and appended claims.

In accordance withone embodiment of this invention, a device is provided for finding the longitudinal centerline of the handle of a piece of table cutlery comprising a base having an element slidably mounted thereon. 'Pivotally connected to the upper end of the slidable element is a pair of self-aligning gripping members. The element is adapted to normally assume a retracted position and the gripping members, a grippin relationship. A means is mounted on the base for actuating the element in a vertical direction whereupon the gripping members assume a non-gripping relationship. Mounted on the base is a bracket having a portion thereof extending above and over the gripping members. A punch is slidably mounted on the extended bracket portion and is positioned in superposed relation with respect to the slidable element.

For a more complete understanding of this invention, reference should be made to the drawings wherein Fig. 1 is a fragmentary side elevational view of the device.

Fig. 2 is a fragmentary vertical section of the device shown in Fig. 1.

Fig. 3 is a fragmentary perspective view'of the overhanging portion of the bracket.

Fig. 4 is a plan view of the device taken alon line 4-4 of Fig.1. 7

Fig. 5 is a perspective view of one of the gripping members.

Fig. 6 is a fragmentary top plan view of the pivotal connection for the gripping members.

Referring now to the drawings and, more particularly, toFigs. 1 and 2, a centering device It is shown comprisinga base ll shown in the form of a block, and a post l2 slidably mounted within a suitable opening it formed within said.

block. The post i2 is actuated in a verticaldirection by means of an operating lever I l, which is pivotally connected at point. IE to the block ii. The enclosed end it of lever It is positioned within a notch ii formed in the periphery of the post 52. The exposed or opposite end of lever it is shaped intoa suitable handle is. The operating lever is adapted to normally hold the post B2 in a retracted position by means of a coil spring is which is secured at one end to block ii and, at the other end, to a lug i9 laterally mounted on the exposed end portion H of said lever. A suitable opening 20 is formed in block I! so as to enable the lever I4 to move about pivot point I5.

To the upper end of post I2 is pivotally connected at point 2! a pair of gripping members or jaws 22 and 23. The gripping members are adapted when the shaft is moved upwardly by lever i l to assume. a nongripping relationship. Suitable'guides or rests 24 and 25 are mounted within a cavity 25', formed in the upper portion of block H and positioned on either side i of post 82, so as to engage and cause the gripping members 22 and 23 to assume a g pp end 3! thereof pointed and case-hardened. The

operation of the punch 39 will be discussed more fully later.

Gripping members 22 and 23 are of like construction, comprising pedestal members 32 and 32a, and jaw members 35 and 35a, respectively, adjustably mounted thereon. The lower end 33 of pedestal member 32 is bifurcated and is adapted to receive a tongue formed in end'33a of pedestal member 32a as shown in Fig. 6. Ends 33 and 33a are embraced by and pivotally mounted on the bifurcated upper end 39 of post I2. The upper portions 34 and 34a, of the pedestal members 32 and 32a, respectively, are enlarged and substantially flat and serve to support the jaw members mounted thereon. The Jew mbers a e se ure to t ns 3. n 3 30. of the pedestal members by means of shouldered holdin'gbol'ts 36 and 36a, respectively, which extend through suitable openings 3} formed in the jaw members 35 and 35a and are threaded into the corresponding pedestal 'n'1emhere. The shouldered shank it? of each bolt prevents the jaw member from being drawn up tightly against the supporting surface of'th'e pedestal member. Thus, each jaw member is adapted to move relative to th'eped estal member. A small amount of clearance 38 is provided in each jaw member between the shouldered shank .3 an th f p of 99 195 and 3662, positioned parallel'to' and spaced from boltsiifi and sea, extend through suitable openmgsrcmied in the jaw members. The ends of 7 pins terminate within the respeetivepedestal m rS T ie l' m mbers fiend. ar l -e em n d p ed o Pi O smu p .9 3 l p q i Th m l f i-TiQ- er Wei em 1 @he' r s se se when" t e." serene m q d wfl h ipw e evergre s. surf ces M a d. til of thejaw members 55, and a, respectively,'are serrated as'shown in Figs. 1, 2, and 5.

Th fre l e at rs formed in t bsi ed e ween the" g ip i members, the,

operatonreleases the lever is, and, the spring i9 forces said into gripping relation unit ect'to the handle, As seen "in Fig. 4, the jaw'm embers are adapted to align themselves with respect to the periphery of. the, handle 42 to be more'firmlygripped therebetweenl After the handle d; has been positioned, as shown in.

4, the operator presses down on the punch 30 causing an indentation or mark'to be v made on the handle by the pointed. tip 3.4, of the punch. The" punch is normally held in its up o r inopt n y 0 1. ring s3, which em: braces the upper portion of the shank. end'of the spring t'engages the upper end of bushing 'ZB'an'dthe other end an enlarged, head statemen the upper end of the punch.

THeTree end portion 27 of bracket 25, see Fig; 3', is provided with an opening 45 to permit a screw driver to be, insertedtherethrough into engagement with the holding bolt 3,561 the gripping member 23 for adjustment thereof. One side ofthe'en'd of portion 21 is cutaway slightly, as shown in Fig. 3, so as to enable the operator to more readily View the work positionedbetween thegripping members.

Thus, it will be seen that a centerin device one,

has been provided which greatly facilitates the operator in performing the engraving operation. Furthermore, the device eliminates uesswork on the part of the operator in determining the correct-location of the engraved design on the handle.
