HOLDDOWN ATTACHMENT FORLASTING-MACHINES.

'PatentedzFeb. 1, 1910.

App1ication filed May 18, 1909. Serial No. 496,734.

To all whon'z. it may conccm:

Be it known that I, EDUARD F. Herrerxan, o'l Brockton, in the county of Plymouth chines, of which the following is a specifica-- tion.

This invention relates to a lasting machine having a spindle for supporting the heel l)()llll)ll of a last, a toe restfor supporting the toe portion of the last,and wipers which are movable lengthwise of the last and over the heel and toe portions of the bottom of the same to wipe the corresponding portions of the edges of the upper over the bottom of the last.v

The invention has for its object to provide improved means for holding down the last and preventing its upward displacement during the lasting operation.

The invention consists 1n the improvements which-I will now proceed to describe and claim.

()f the accompanying drawings, forming a part of this spec1ficat1on,-F1gure 1 represents a side elevation of portions of a lasting machine provided with my'improved attachment. Fig. 2 represents a section on line 2") of Fig. 1. a

The same reference characters indicate the same parts in both figures.

In the drawings,12 represents the frame of a. lasting machine which is provided with the usual support 13 for the heel portion of a last 14, said support being formed as 'a spindle adapted to enter the usual spindle socket in the last, a. toe rest 15 adapted to support the toe portion of thelast, and suit- 1 able wipers 1G and 17 which are movable longitudinally over the bottomof, the last, and are adapted to wipe the heel and. toe portions of the margin of an upper over the correspomling portions of the bottom of the last. The ma chine including the parts above mentioned may be of any suitable construction, and operated in any suitable manner.

In carrying outmy invention, 1 provideas an attachmentfor a machine of lht character stated, a hold down adapted. to be applied to the bottom of the last between the heel and toe-wipers, and to be quickly applied to and removed from the last, and dis placed to a position at one side of the lastwhen its use is not required, the attachment as a whole being adapted to firmly support the last againstupward displacement during the lasting operation.

-My improved 1 attachment comprises a standard 18 havingmeans for engagement with the frame 12, the means here shown comprising a socket 19 to which the standard 18 is attached by set screws 20, said socket having ears 21 attached by screws 22 to a portion of the frame 12, said portion being so located that when the standard is in place, it occupies a vertical position at one side of the space occupied by the last.

'23 and 24 represent arms mounted to swing in unison upon the standard 18, said arms being located at different heights on the standard. The upper arm 23 1s elongated and formed to bear uponthe bottom of the last 14, or upon an inner sole placed thereon. The lower' arm 24- is considerably shorter than the upper arm, so that it may project from the standard under the upper arm without coming in contact with an adjacent part of the machine. The lower arm 24 is confined against vertical movement on the standard by means of collars 25 and 26 which are adjustably secured to the standard by m'eansof set screws '27. The upper arm is vertically movable on the standard so that it may be raised and lowered as indicated by full and dotted lines in Fig. 2. The arms 23 and 24 are provided with adjusting means having provisions for vertically a justing the upper arm, confining it against vertical movement at any position towhich it'may be adjusted, and resisting upward pressure of, the last against the upper arm, said adjusting means being adapted to swing horizontally with the arms. In the eml'iodiment of my invention here shown, the said adjusting means include a. rod 28 which is journaled in a bearing 01' socket formed for its reception in the inner portion of the upper arm, said rod being freely rotatable in the upper arlnand con} fined against endwisc movement relatively thereto by collars 29 attached'by set screws 30 to the rod and bearing against the upper and lower edges of the upper arl'n. The

lower portion of the rod 28 is screw thread-c ed and engaged with an internally threaded socket formed for its reception in the lower to position to cause the upper arm to proit may be adjusted, and resisting upward pressure against the upper arni.-
