PATENT ioF ic v 1.30M As, OFAEAST HAM, IJO'NDOEYENGLAND, n'ssreno'nro Ufs. sLicINe MA- CHINE COMPANY, or LA POE-TE, INDIAnA, a ooRroR'A'TIoN OF INDIANA SLICE nEFLEo'ron FOR sLIcinG MACHINES;

iApplication filed September 16, 192-7. 'Serial No. 219,829.

This invention relates to deflectors for' directing slices away from the rotary knives ofsli'cing machines, and has for one of its 1 objects the provision of a support for deflectors :of this nature which will hold the deflector in position adjacent the face of the slicing knife so that the deflector will not be moved out of position by the slices engaging theedge of the deflector.

which the force of the slices, as'they are being cut, tends to hold the. deflector n its locked position. I A further object is to provide, a deflector which will overlap its support when in operative position to 'preventany gap or open space between the deflector and support.

A further object is to provide anlad ustable support for the deflect-or which will permit'the edge of the deflector to be .adjusted relative to the I face of the slicing knife.

Other objects and advantages will appear from the following description.

The invention is exemplified in the combination and arrangement of parts shown inthe accompanying drawing and'described in the following specification, and it is more particularly pointed out in the appended claims. I c

In the drawing- I Fig. l is an elevation of a portion of a slicing machine knife showing one embodr ment of the present invention applied thereto; 1

Fig. 2 is a top plan view of thedeflector shown in Fig. 1; 1

Fig-3 is a section enline 3-3 of Fig. 1; and s Fig. 4 is a'view similar to F1g; 3', but showing the parts in a CllffBIQIIt' pOSItiOIL This'invention is somewhat similar to the device shown in my prior application, SerialNo. 141,484, filed October14, 1926, but shows a different form of pivotal support forthe'deflector. j v

The numeral 10 designates the bearing support fora slicing machine knife 11 which is journaled at 12 on the support 10. A plate 1'3Lis securedto thefside of the support 10 by screws 14- and is provided wi'th flaterally projecting brackets 15 having bearing openings 16 therein. The brackets 15 are pro- A further object is to provide a deflector which is locked in operative position and 1n.

vided with slots 17 which "communicate with the inner 's'ides of the openings '16. The deflector. plate 18 '-1svprovided with inward- 1y projecting ears l9 and 2O. .The ear 19 carries a downwardly projecting lug 21 of,

a-size and shape to fit into the opening 17 in the lower bracket 15. The ear 20 carries an upwardly-projecting lug 22 shaped to fit within the opening 17 of the upper brack-' et'15. Spring rings '23 disposed in the openlugs 16 in the brackets 15 retain the lugs 21 and 22in position in the slots 17-. The'rings 23 .areopen at one side and the lugs 21..and

,22. are;provided with rounded edges which 'i engage-the open ngs in .theyrin-gs. .=So long as the lugs 21,-and 22 are positioned inthe slots; '17, the deflector 18 will'beheld in placeagalnst thefaceofqthe knife 11. When it is desired toswingthedeflectoroutwards 1y away from the knife, this may be done by pressing the defiectonto the, right, as viewed in thefdrawing, to m'oVethe lugs21. and 22 through the openings {in the. rings 23 until ,they occupy a position within the interior of the rings 23, as shownjin Fig.

4. The deflector l8maylthen be swung'outwardly, as indicated in Fig, 4,. the rings '23 rotating in the openings 16; to provide a pivotal support for-the deflector 18. ,The deflector 18 is provided with an opening 24Jto ,permitthe insertion'of the operators thumb or fingers to shift the deflector for moving the lugs 21 and 22 into "and out of engagement with the slots 17. A reinforc ing bracket 25 surrounds the opening 24' and bracesfthe ears"191and 20, which support the lugs 21 and 22. i

.In-tghe operativeposition of the deflector,

the lugs '21 and 22 are engaged invthe slots 17 and the rounded ends of the lugs register with the gaps in thefrings 23am]. the deflector is thus locked against turning movement. When'the vdeflectoris shifted toward the edgeof the knife to release the lugs from the slots-'17,}therings :23 will be. sprung outwardly into frictional contact with the inner faces of the openings16 an'd'thus serve to maintain the deflector in any position into which it may be swung. 'Oo -operating stops '26 and 27 on thedeflector 18 and the supporting brackets 15, respectively, are. prov-ided for guarding againstaccidental move- I ment of the" deflector into- "contact with the face "of 'the'jknifeg When the deflector is shifted to the right as viewed in the drawing out of its operative position, the stops 26 on the deflector move into a position which registers with the stops 27 the deflector being thus prevented fromswinging further toward thelknife" than the amount determined by thestops 27. Cover plates 28 are fitted on the outer surfaces of the brackets to close the openings 16 and prevent ingress of grit to the rings 28. The upper cover plate is removed in Fig. 2 for the purpose of clearance. Openings 29 are cut inthe walls of the brackets 15 to permit the lugs 21 and 22 to pass when fitting the deflector into position in the supporting brackets or when removing the deflector from its brackets. The plate 13 is attached to the knife bracket 10 by screws 14, as previously explained, the

' screws being arranged to permit the plate to its: adjusted positions.

inclination of the deflector to the knife can be adjusted at will. It should be noted that when the deflector is in its operative position move through a slight angle and a grub screw 30 is provided tohold the plate 13 in By this .means the the pivotal point thereof is moved back'toward the support 10 to such ZL'POSIUOII that the rear edge of the deflector overlaps the supporting member so that no joint is visible between the deflectorand support.
