COBBLERS WORK SUPPORT.

application filed May at,

To (1% whom it may concern:

Be it known that 1, JAMES Sawrnowsnr, a citizen of the United States, residing at Augusta, in the county of Richmond and State of Georgia, have invented certain new and useful improvements in Cobblers Work Supports, of which the following is a specitication.

In carrying out the present invention it is my object to provide a work support for cobblers that comprises essentially a last and a jack for the same, the primary object thereof being the provision of such work support wherein the jack may be readily secured at a convenient point upon the work bench and wherein the last may be turned upon the jack for permitting the shoe to be operated upon at different sides without the necessity of removing the shoe from the last and then reversely positioning the same which is now the general case with other, work supports with which i am now familiar.

A further object to the invention is to provide a work support that is primarily but not specifically adaptedfor use in conjunction with the sewing hand turned half soles, that is extremely simple of construction and inexpensive of manufacture and one that will embrace at the same time the desired features of simplicity and durability.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawing,

the invention residing in the construction, combination and arrangement of parts as claimed.

In, the drawing forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein:

Figure 1 is a side elevation partly in crosssection of my improved device, the same be 'ing shown as positioned upon a work bench, and

Figure 2 is a fragmentary perspective of the last per se.

With particular reference to the drawing, the device comprises essentially a jack 5, and a last 6, one end of the jack being bifurcated at 7 and adapted for extension over the edge of a work support A and to be secured thereto through the medium of a screw threaded bolt 9 that engages through a screw threaded opening in the uppermost Serial No. 641,279.

opposite end of the jack 5 is formed with a vertical bore 11 that receives a pendent rod 12 formed upon the lower end of the last 6. One end of this rod 12 is screw threaded for the reception of a wing nut 13 whereby the last may be secured to the jack.

The last includes a base plate 14 that is formed with a pair of sockets into which are inserted filler blocks 15 of wood or other desirable material whereby the shoe may be conveniently nailed to the last and held thereon during the sewing of the sole.

It will be noted that the last 6 is formed of a curved arm having an upright portion 6 curving away from the axis toward the upper end at which 'is formed the return bend 6 forming the head 14L providing the shoe receiving portion and forming an inverted last. In this manner, the connection between the portions 6 and 6 receive the upper of the shoe Without distorting the heel portion and the portion 6 returns to the axis of the post 6 as defined by the bolt 12, in order that the parts of the structure will be distributed in relation with each other to distribute the force or stresses applied there to equally over the lower end of the post 6 to provide a firm backing for supporting the work. In providing the arm 5 in connection with this last, a support is provided for the last at a distance from the edge of the work bench A and carried by the top of the bench so that the cobbler may work in practically any position about the last without leaning over the edge of the work bench, and the slightly upwardly curved portion of the arm as indicated at 5 cooperates with the formation of the last to distribute stress applied to the portion 6* in such a manner that it will be directed against the edge of the table A for distribution horizontally thereof. This distribution of stress may be determined by a line drawn from the edge of the table A to the forward insert 15 which will indicate the distribution through the relative curvature of the last 6 and the arm 5, and from the base 5 to the edge of the table.

In view of the above description it will at once be apparent that when a shoe is positioned upon the last and it is desired to turn thesame all'that is necessary is to release the nut 13 and rotate the last upon the jack. 7

From the foregoing description, taken -in connection with the accompanying drawing, the advantages of construction and the mode of operation of the invention will be readily apparent to those skilled in the art, and while I have described the principles of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are Within the scope of the appended claims.

Having described my invention, what I claimand desire to secure by Letters-Patent, 1s: 7

1; A cobblers work support comprising a bracket embodying a relatively long arm provided at one edge with means for detachable clamping engagement with the edge of a horizontal bench top or the like, wherei by the arm may be rigidly supported in a substantially horizontal position from the bench, the upper face of the outer end of the arm being formed to provide a flat bearing surface, the outer end of the arm having, a vertical transverse opening through the upper and lower sides thereof centrally of said bearing surface, and upright last.

carrying posts having a fiat lower end adapted'to rest upon said side bearing surface of the horizontal arm and provided with a depending rigid vbolt extending through the vertical opening in the arm, whereby rotation of the last about its vertical axis and relative to the arm maybe had for adjusting the last angularly relative to said arm, said post having an integral inwardly extendingand then outwardly extending upper end portion forming an inverted last and: work support, and a wing nut threadably 'mounted on, the depending bolt below the horizontal'arm for engagement therewith tor-secure the post to' said arm; V

2. A cobblers work support including an arm formed at one end with a bifurcated portion for engagement over an edge of a bench top or the like for firm contact therewith having means associated with the bifurcation adapted to secure the arm to said top, the arm extending substantially horizontal and having a slight upward curve to position the lower surface of the outer end slightly below the plane of the upper sur-' face of theotlier end of the arm, said outer end being provided with a bearlng surface on the upper side and a vertical transverse opening through the arm located centrally of the bearing surface, a last formed with a vertical portion provided with a bearing through the axis and forming an inverted last 7 and work support, the curvature of the arm and last cooperating to distribute a portion of the stress applied thereto in a substantially horizontal direction at the edge of the bench top whereby a firm support is provided forthe work at a point spaced beyond the edge of the bench top.

In testimony whereof I afiix my signature.

JAMES SAWILOWSKY.
