DASHER FOR lCE-CREAIV] PREEZERS.

SPECIFICATION forming part lof Letters Patent No. 609,322, dated August 16, 1898. Application iiled October l, 1897. Serial No. 653,718. (No model.)

To @ZZ whom it may concern,.-

Be'it known that I, CHRISTIAN AIGHELE, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in vDashers for Ice'- Cream Freezers, of which the following is a specification.

One object of my invention is to provide the dasher of an ice-cream freezer with scrapers so arranged that they will, so long as the can or dasher is rotated, be caused to constantly bear against the inner surface of the can, and thus remove the frozen cream therefrom as fast as it is formed, a further object being to so construct'the scrapers and the pintle-plates whereby they are hung to the dasher-arms that each of said plates may be secured to the scraper by means of a single screw or bolt. These objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawings,in Which- Figure 1 is a vertical sectional view of an ice-cream can having a dasher with scrapers constructed and mounted in accordance with my invention, and Fig. 2 is alsectional plan view of the same.

The can 1 may be of any suitable character, and the dasher 2 may also be constructed in any desired way so long asv itis provided with projecting arms 3, to which the scrapers are hung Each scraper 4 consists, as usual, of an upright blade or strip, preferably of wood and having a beveled or sharpened outer edge for bearing against the inner surface of the can, each scraper having a pair of pintle-plates 5, each with projecting pintle 6, that of the upper plate extending upwardly into an opening in one of the upper arms 3 of the dasher and the pintleof the'lower plate extending downwardly into an opening in one of the lower arms 3 of said dasher. The pintle-plates 5 are, however, so located upon the scraper that vertical play of the pintles in the arms of the dasher is permitted, and the scraper normally projects so far below the lower arm of thedasher that when said dasher is introduced into the can the lower end of the scraper' will strike the bottom of the can before the pivot pin orstep at the lower end of the dasher finds its bearing `rib 7, as shown in Fig. 2,

scraper will cause the same to swing outwardly, as represented by the arrow y in Fig. 2, so as to press its beveled or sharpened outer edge constantly against the inner face of `the can, and thus remove the frozen cream therefrom as soon as itis formed. By this means I amv enabled to effect the outwardQ swinging movement of the scrapers by means at once simple, cheap, and effective, as no more parts are required than are necessary in hanging any ordinary scraper to the dasher. 7o

Each scraper has on the back a projecting and each of the pintleA-plates 5 has opposite edge flanges 9, so that said rib 7 on the back of ,thescraper is embraced by the pintle-plate, and the latter thus has so iirm a hold upon the scraper that it may in the smaller sizes of freezers be secured to the scraper bya single screw or bolt 10, as shown in Fig. l, insteadlof by a pair of screws, such as are usually required.

The outer shoulder of the rib 7 and the outer hangs 9 of the pintle-plate are beveled `on their meeting faces, as shown in Fig. 2, so

that when the screws 10 are tightened there will be a snug fit of the flanges 9 to the inner and outer faces of the rib 7 and a iirm fastening of the scraper to the pintle-plates.

Having thus described my invention, I claim and desire to secure by Letters Patent-a l. The combination of the dasher of an icecream freezer with afreely-swinging scraper mounted so as to have vertical play on said dasher, the bottomof the scraper, when the dasher is inserted in the can, resting upon the bottom of said can, whereby the rotation of the can or dasher will tend to swing the scraper outwardly.
