Noteworthy among the features of the novel dougnformewaecording to the present invention are its simplicity and ruggedness of construction, the former suiting the device to the requirements of manufacture under conditions of mass production and the latter assuring long useful life.

Other objects, advantages and features oi the new and improved dough former according to the present invention will be apparent to those skilled in this art during the course of the following description.

Regarded in certain of its broader aspects the improved mounting means according to the present invention for holding trunnions of rollers and the like in open slot-like formations in the form of a dough forming machine comprises flanged sleeves, freely rota'tably receivable on the trunnions, having openings formed in peripheral parts of the flanges, the sleeves having an external size permitting fitting into the slot-like formations of the frame; and spring-urged sliding latch members mounted in the frame, adapted 55 broken away,-

In the illustrated presently preferred embodiment of this invention generally designated by the reference character ID a base II is provided upon which are rigidly mounted spaced essentially parallel upright standards l2 in upper parts of which is mounted a horizontally extending freely rotatable feed roller 13 substantially cylindrical in shape and having trunnions M which are received in openings formed in the standards. A handle l5 mounted by means of a set screw I5a upon one of the trunnions I4 is provided to facilitate manual rotation of the roller I3. The U- shaped frame element generally designated by the reference character I-fi comprising a cross piece Ma and integrally formed arms l'fib is swingably mounted upon upper parts of the standards l2 by appropriate fastening means such as the screws I60. The cross piece lfia of the frame IE is adapted to overly the roller I3 hereinabove described and the arms lBb are pro vided with aligned cut-away formations to receive trunnions Ila of a former roll I! which rests upon yielding intrinsically resilient support. ing members I 8 mounted upon parts of the standards l2. The former roll I! is substantially cylindrical in shape and is provided with spaced V- shaped cutters Ilb which, when dough is passed through the machine upon the feeder roll I3, form the dough into continuous strips as will be obvious to those skilled in this art. It is to be noted that the axis of rotation of the rollers l3 and I! are substantially parallel and are adjustable with respect to each other by means of a screw l9 mounted in a U-shaped frame 20 pivoted to parts of the standards I2 by pins 20a. As will be obvious from the drawings the screw l9 bears against a part Ilia of the U-shaped member 16 whereby the roller l1 can be pressed against the roller l3 despite the upwardly directed force of the resilient members I8. In order that the rollers l3 and I! may rotate at the same speed, gears 2| and 22 are mounted upon the trunnions l4 and Ma respectively. A doctor blade '23 mounted upon a cross bar 24 cooperates with the feed roller I3 to remove material clinging to the surface thereof as will hereinafter be described.

Aligned obliquely disposed open slot-like formations 25v in upper parts of the standards l2 serve to receive sleeves 26 having integrally formed radially extending flanges 21 within which is freely rotatably received a shaft 28 of a transverse cutter assembly generally designated by the reference character 29. The shaft 28 carries rollers 3|! rigidly attached thereto by pins 3| having radially extending fins 30a upon which are mounted horizontally disposed blades 32 attached thereto by appropriat fastening means such as screws 32a, the blades being adjusted preferably to pass substantially near the feed roller l3 during rotation of the shaft 28. A gear 33 rigidly mounted upon th shaft 28 meshes with a similar gear 34 rigidly mounted upon the trunnion I 4 whereby rotation of the trunnion I4 results in rotation of the shaft 28 and the cutter blades 32 in addition to rotation of the former roller I! as hereinabove described.

Pins 35rfreely slidingly received in openings 36 formed in parts of the standards l2 are urged toward the flanges 21 carried on the sleeves 26 by springs 31 sleeved upon diminished portions 350. of the pins substantially as shown. End portions 35b of the pins 35 project outwardly from the surface of the standards l2 and are received in registering openings formed in the flanges 21 whereby the sleeves 26 are retained within the slot-like formations 25 in the manner illustrated in the figures of the drawings. To facilitate manual sliding motion of the pins 35, handles 33 are provided, the handles also serving to prevent the pins from moving to an undesired. degree under action of th springs 31. For facilitating sliding of the pins 35 against the action of the springs 31, cams 39 are provided upon side parts of the frame l2 against which the handles may ride when the pins are swung about their axis.

Having described the structural features of the presently preferred embodiment of this invention the mode of operation thereof will next be described although it is believed that the operation of the device will be substantially apparent from the foregoing description. Dough is fed between the rotating rollers l3 and I1 whereby the V-shaped formation ll-b on the surface of the roller l1 serves to press the dough into a continuous sheet having longitudinal furrows formed in the top surface thereof. It will be recalled that rotation of the feed roller l3 produces concomitant rotation of the former roller I1 and. also of the shaft 28 carrying the cutter blades 32. As the blades move against the roller l3, the furrowed dough is transversely cut and the out product is removed from the roll l3 by the doctor blade 23.

It is to be understood that this invention is capable of extended application and is not confined to the precise illustrated forms nor described construction and, therefore, such changes and modifications may be made therein as do not affect the spirit of the invention nor exceed th scope of the appended claim.

Having thus described the present invention, what it is desired to secure by Letters Patent is:

Improved mounting means for holding trunnions of rollers and th like in open slot-like formations in the frame of a dough forming machine comprising flanged sleeves, freely rotatably receivable on the trunnions, having openings formed in peripheral parts of the flanges, the sleeves having an external size permitting fitting into the slot-like formations of the frame; and spring-urged sliding latch members mounted in the frame, adapted to engage with the peripheral openings in the sleeve flanges whereby the sleeves can be removably held within the formations in the frame.
