Home, a en of Hollench residing at county 01 Monroe and orlz, have invented certain res. sncl useful improvements in Breadnig lliiachines, of which the tollowing is s specification,

illlS iliYGilllOll relates to breoo cutters and s for its object to provide an automatic an ine provided with a continuously 5g l'niie in which t e brez Cl is fed forin orin distance for each revolution knife so that it wiil be cut in slices of hicitness.

also provided by which the the slices cut may be varied at eljustinent provided therefor. .5. .th r objects of the invention will be fully illustrated in the (ll'i'lfiiilQjE-i; described in the specification and pointed out in tlie claims at the end thereof.

The troitigh is channel shaped and the bottom of it is slightly lower than the channel 8.

The operation of the machine is as follows:

The knife may he placed across the opening in the upright .l.. The loaf of bread is then placed on the channel 8 with its cud against the knife. The carriage is then brought forward into engagement with the rear end of the loaf of bread and the upper jaavis closed down on it forcing the cud of the leaf into engagement with the lower jaw, The carriage is then engaged with the feed screw and he handwhecl is then rotated causing the loaf to he ted to the lmil e and cut in slices.

I claim:

1. In a bread cutter, the combination of a frame having a base, a traveling carriage, a feed screw for advancing said carriage, means for turning; said screw intermittently through a fixed angle, said means comprising a drum, a chain attached to and partially wound on said drum at one end, a rocking lever to which. the other end of said chain is attached, means for intermittently rocking said lever.

2. In a bread cutter, the combination of a frame having a base, a traveling carriage, a feed screw. for advancing said carriage, means for turning said screw intta'mitl'ently through a fixed angle, said means comprising' a drum, a, chain attached to and partially wound on said drum at one end, a rocking lever to which the other end of said chain is attached, means for intermittently rocking said lever in one direction, a spring on said drum for rocking said lever in the other di rection, said Il'lCtlllS for turning said sL-rew being adapted to rotate said screw in one direction by the oscillations of the drum.

3. in a bread cutter, the combination of a frame having a base, a traveling carriage, a fecdscrew toadvancing said carriage, a ratchet wheel on the end of said feed screw, a drum mounl'c d to rotate on said feed screw, a spring pressed pawl mounted on said drum and engaging said ratchet wheel, a chain attached to and partially wound on said drum at one end, a 1'0 king" lever to which the other end of said chain is attached, means for intern'iittcntly rocking said lever in one direction, a spring on said drum for rocking said lever in the other direction, said pawl being adapted to intermittently turn said feed screw in one direction on the oscillation of said drum by said chain.
