BREAD OR CAKE CUTTER.
SPECIFCATION forming part of Letters Patent No. 640,916, dated January 9, 1900.
l Application fled April 27, 1898. Serial No. 678,982. (No model.)
T0 aZZ whom it may concern:
Be it known that I, JENS JENSON, a citizen of the United States, residing at Page, in the county of Cass and State of North Dakota, have invented a new and useful Bread or Cake Cutter, of which the following is a specication.
My invention relates to a bread and cake cutter, and has for its object to provide in a device of this class for a combined oscillatory and reciprocatory movement of a blade, the reciprocatory movement being rapid in proportion to the oscillatory or swinging movement in order to simulate the manual operation ofaknife in cutting materials of a cru mby nature.
Further objects and advantages of this invention will appear in the following description,and the novel features thereof will be particularly pointed out in the appended claims.
In the drawings, Figure 1 is a perspective view of a cutting apparatus constructed in accordance with my invention. Fig. 2 is a detail sectional view of the oscillatory frame or blade-carrier, taken in the plane thereof to illustrate the means whereby the reciprocatory movement is imparted to the blade.
Similar numerals of reference indicate corresponding parts in both figures of the drawings.
l designates a base or cutting-table which is preferably provided with a side guide 2, and at the front end of the cutting-table is a transverse bar 3 for supporting a guide-frame consisting of an upright 4, a segmental bar 5, and a brace 6, said brace being secured to the upper end of the segmental bar by means of a set-screw 7 and being held at the other end in an opening in the upright 4. by means of a second set-screw 8.
Mounted at one end in a journal-block 9 at one end of the transverse bar 3 is an oscillatory arm or knife-carrier 10, having a guideopening 11, through which said segmental bar 5 extends, and being extended beyond said bar to form a grip l2. The carrier is provided contiguous to its extremities with alined guides 13 and 14, the latter consisting of a stirrup depending from. the body portion of the arm `and the former consisting of a laterally-open seat. The blade or knife 15, which is preferably provided with a serrated cutting edge, is fitted with terminal parallel-sided extensions or tongues 16 and 17, which lit, respectively, in the guides 14 and 1.3, the tongue 17 being secured in the laterally-open seat 13 by means of a removable key 18, which in turn is fitted in a cross-sectionally dovetailed seat 19, intersecting the seat 13.
The segmental bar 5 is preferably toothed to form a rack-bar, and mounted in a cavity formed in the stock or body portion of the operating-handle or carrier is a pinion 20,
permanently meshing with said rack-teeth and adapted to receive rotary motion alternately in opposite directions during the 0S- cillation of said carrier or handle. In the construction illustrated this pinion is loosely mounted upon a spindle 21, which is journaled in the carrier and projects through a removable cap-plate 22, which closes the abovementioned cavity in said carrier, the outer` extremity of the spindle being iitted with a crank-disk 23, having a wrist-pin 24., which is connected by a link or pitman 25 with a lateral pin 26 on the contiguous tongue 17 of the blade. A clutch connection, consisting of a ratchet 27 and a spring-actuated pawl 28, is employed to communicate rotary motion from the pinion to the spindle 21 during the rotation of the pinion in one directionnamely, during the descent of the free end of the carrier or operating-handle-while during the opposite movement of said carrier the pinion turns idly upon the spindle. Thus in operation the oscillatory movement of the carrier or handle causes a rapid reciprocatory movement of the blade during the downward movement of the carrier, such movement of the blade being similar to that which is imparted manually to a blade in cutting such objects as bread and cake, the advantage of the rapid reciprocatory movement being to prevent the excessive crumbing or crushing of the material. Furthermore, all of the parts of the apparatus are detachable, the` crank-disk 23, which may consist of a device of any similar construction adapted for converting the rotary motion of the spindle 21 into a reciprocatory motion of the blade 15, being secured to said spindle 21 by means of a pin 27. Obviously when this disk or its equivalent is removed from the spindle the cap-plate 22, which is held in place by suit- IOO able screws, may be displaced to give access to the pinion and clutch mechanism, whereby motion is communicated from said pinion to the spindle. .Y
In addition to the above-described mechanism I also preferably employ an adjustable gage or stop 28, arranged parallel with and spaced a greater or less distance vfrom the outer'edge of the transverse bar 3, said gage consisting of a bar fitted for sliding movement upon guide-pins 29, yieldingly held at an interval from the bar 3 by means of coiled springs 30 and secured at the desired adjustment in opposition to the tension of said springs by a setscrew 3l, which extends through the bar and is threaded into the frame of the device.
Various changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of this invention.
Having described my invention, what I claim isl. In a cutting apparatus, the combination of an oscillatory carrier, a reciprocatory cutting-blade mounted upon the carrier, and means for producing a plurality of strokes of the blade during each complete stroke of the carrier, substantially as specified.
2. In a cutting apparatus, the combination of an oscillatory carrier, a blade mounted for reciprocation upon the carrier, and means for producing a plurality of strokes ot' the blade during each swinging movement of the carrier in one direction, substantially as speciiied.
` 3. In a cutting apparatus, the combination of an oscillatory carrier, a blade mounted for reciprocation upon the carrier, a fixed rackbar, a pinion mounted upon the carrier and meshing with said rack-bar, and operating connections between the pinion and said blade for communicating reciprocatory motion to the blade independently4 of the carrier, substantially as specified.
4. In a cutting apparatus, the combination of an oscillatory carrier, a reciprocatory blade mounted thereon, a Iixed rack-bar extending through a guide in the carrier and arranged concentric with the pivot thereof, a pinion mounted upon the carrier to traverse the rackbar, a spindle having a clutch connection with the pinion,and connections between said spindle and the reci procatory blade, substantially as specified.
5. In a cutting apparatus, the combination of an oscillatory carrier having a terminal grip, a fixed rack-bar, a pinion mounted upon the carrier to traverse the rack-bar, a spindle having-a clutch connection with the pinion to receive rotary motion therefrom, a crankwheel carried by the spindle, and a pitman connection between the crank-wheel and the reciprocatory blade, substantially as specified.
In testimony that I claim the foregoing as myown I have hereto aiiixed my signature in the presence of two witnesses.
