COMBINED CRlMPlNG-WHEEL AND TURN-DOWN FOLDING ATTACHMENT TOR SEWING-MACHINES".

SPECIFICATION forming part of Letters Patent No. 433,930, dated August 12, 1890.

Application filed September 2, 1.889. Serial No. 322,680. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE BoXLEY, of the city of Troy, county of Rensselaer, and State of New York, have invented a new and useful Improvement in a Combined Crimping- \Vheel and Turn-Down Folding Attachment to Sewing-Machines, and of which the following is a specification.

My invention relates to an attachment to sewing-machines, having for its object the crimping of the down-fold produced in the fabric coming from a hemmer or folder and an improved construction of the latter. 7

Accompanying this specification to form a part of the same is a sheet of drawings containing three figures illustrating my invention, with the same designation of parts by letter-reference used in all of them.

In the illustrations,-Figure 1 is a perspective of a sewing-machine with my improved crimpingwheel applied thereto. Fig. 2 is a section taken on the line m x of Fig. 1, and Fig. 3 is a section taken through the hemfolding attachment on the line a x of Fig 1.

The several parts of the mechanism thus illustrated are designated by letter reference, and the function of the parts is described as follows: The letter TV designates the drivingwheel, A the stationary arm, A the needlearm, B the needle-bar guide, N the needle, L the presser-bar lever, and T the work-plate,' all of which parts are of the usual and ordinary construction.

The letter D designates a downwardly-projecting arm or leg that at its upper end 6 is attached to the needle-bar guide B and at its lower end e is constructed with a bearing 6', having arranged to turn thereon the shaft S. This shaft has upon it a crimping-wheel O,

made with a fluted face f, and is arranged to i be over the slots S in which the feed-bar F is moved. This feed-bar by an eccentric E, arranged between said bar and the drivingshaft 8*, is caused to rise and move forward, v

to descend and again move forward intermittently, by means of said eccentric connecting with the driving-shaft and its guide G on its outer end. The upper rear end of this feed-bar is serrated, and when actuated to rise and move horizontally forward it works in the slots S made in the work-plate and directly beneath the crimping-wheel O.

The letter P designates a plate made with a slot S and adapted to connect with the work-plate of the'machine by means of the set-screw .T, and F is a turndown-folder mechanism constructed with the fold-guide plate p attached at a tothe plate P and therefrom curved upward horizontally and then downwarchso as to have its free end rest horizontally on the work-plate of the machine.

The letter 19 designates the turn-down foldplate made with the infold edge a which is attached to the hin gingrod h, the latter making ahi'ngingconnection with the strap-plate p at 71, ,and. at its rear end is provided with a small crank, 70, which latter at its outer end is pivoted to the rod R, and the latter at its end opposite to where making a crank-connection with the hinging-rod h is pivoted to the lever L which latter is pivoted at 19 so that as said lever L is operated horizontally on its pivoted connection the hinging-rod h is actuated to turn about a quarter of a revolution,and thus throw up orv down the foldplate' 29 as indicated by the dotted line cl of Fig. 1. \Vhen turned. down, this fold-plate p rests on top 'of the in-fold 1', made in the curved guide-plate 13'.

As thus made and arranged, the fold-plate 19 being raised by the action of the lever L and the edge of the fabric to be hemmed .be-' ing passed in beneath the guide-plate p, with the lever L operated to turn down the fold plate 19 the edge of the fabric is turned down, in which condition it passes to the crimpingroller, where between the fluted face of the latter and theserrated face of the feed-bar the fold made in the fabric edge is crimped into the latter to pass to the needle to be sewed. As thus made not only can a Welldefined and uniform infold be made in the edge of-the fabric, but, if desired, a strip or tape may be run in between the doWnfold and the fabric-body and a crimped finish given to the sewed parts. This arrangementenables the operator to keep the downfold in shape .while turning corners with rapidity.

illustrated as having attached thereto a binder and 'double -fold hemmer, I disclaim said binder and double-fold hemmer as a part of the invention herein,they being made a matter of a separateapplication, Serial No. 322,679,

filed September 2, 1880.

Having thus described iny-invention, what I claim, and desire to secure by Letters Patrated upper edge constructed to be operated in a slotted work-plate, substantially as described, of a fluted crimping-wheel journaled onto the lower end of a downwardly-projected arm and arranged to engage with the upper surface of the fabric as moved by the feedbar, substantially as described, a turn-down and hinged folder-plate made with an infolding edge and operated by a crank on its hinging-rod, and a rod connecting said crank with a pivoted lever, substantially in the manner as and for the purposes set forth.

Signed at Troy, New York, this 11th day of April, 1889, and in the presence of the two witnesses whose names are hereto written. GEORGE BOXLEY. WVitnesses:

CHARLES S. BRINTNALL, W. E. HAGAN.
