NITED STATES JOHN HEWITT, OF NEW YORK, Y.

lMPROVEMENT I-N SAD-IRON CRIMPERS.

Specification forming part of Letters Patent No. 135.550, dated February 4, 1873.

To all uhom it may concern:

Be it known that I, JOHN HEWITT, of the city, county, and State ot' New York, have invented certain new and useful Improvements in Sad-lron Orimpers, of which the following is a full, clear, and exact description, reference being had to the accom-panying drawing and the letters of reference marked thereon making part of this specitication, in which- Figure l is a side view, partly in section. Fig. 2is an end View. Fig. 3 is a View in perspective ofthe crimping-plate.

My present invention in crimping-machines is an improvement on a device embraced in a former application,and in which a detachable corrugated shoe-plate is broadly claimed.

The nature of my invention consists in pro- Vididing for use, iu connection with any suitable handleblock or equivalent device, a dei tachable corrugated shoe-plate, when said plate is ot' such form as to permit ot'its entire surface being covered with corrugations that are of uniform length.

The construction and operation of my invention are asfollows: A is a block or plate, which is constructed out ot' any suitable material and is of such form that the corrugated plate B or series, of plates to be used in connection therewith will tit the same, the block resting on the upper face ofthe plate l and between its bearings b b. c is the handle and is cast with or otherwise connected with the block or plate A by any suitable means. l5 is the detachable uting shoe-plate and is cast, stamped, 0I' otherwise formed out of sheet metal or any other suitable material. This plate B has corrugatious L b running the whole length of the plate and covering its entire surface. The form ot' this plate B is square or rectangular. This plate has cast with it, stamped on it or otherwise attached, bearings b b, by means of which, through shoulder and pin or other suitable attachment it can be fastened to the handle-block A. This permits of the plate being secured on and removed from the block at pleasure, and has thefnrther advantage of permitting a. series ot' plates with diterent size corrugations being used in connection with a single block. These bearings b b are shown in Figs. l and 2 as being at the ends of* the plate, but there is nothing arbitrary about this, as they may be at any desiredpoint and ot any suitable style; and, when the plate B is formed of sheet metal, they may be so formed as to he sprung over the block A and held through the elasticity of the metal and without any other attachment.

What I claim as new, and desire to secure by Letters Patent ofthe United States, is-

The corrugated shoe-plate B, having suitable bearings to connect it with a handleblock, A, or equivalent device, when said plate is ot' such form as to permit of its corrugations b b covering the entire surface of the plate and of their being ot uniform length, so as to permit ofthe tluting heilig ironed with the flat surface ot' the plate, substantially as described. 1n testimony' whereofl have signed my name to this specification in the presence of two subscribing witnesses.
