SPECIFICATION forming part of Letters Patent No. 750,599, dated January 26, 1904, Application filed September 1, 1903. Serial Nol71,54=7. (No model.)
1'0 whom it may concern:
Be it known that I, HENRY A. CHRISTENSEN, a citizen of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented new and useful Improvements in Bar-Cutters, of which the following is a specification.
This invention relates to what Ishall for convenience term a bar-cutter, as primarily it is intended for cutting strips of fig cakes into bars. The device, which is simple in construction and effective in operation, may be employed with equal facility in other connections, it not being my intention to limit the same to any particular use. The device, however, has been found of particular advantage in the cutting of fig bars, as will appear fully in the followingdescription. Ordinarily strips of fig cake are cut into bars by rotating hand-operable knives, which are diificult to roll along perfectly-straight lines. The result when the course of these knives deviates is that the bars are imperfectly cut. Another disadvantage attending the ordinary method is that the bars or cakes stick to the knives.
'By my device these disadvantages are wholly overcome. Said device in one simple adaptation thereof is clearly illustrated in the accompanying drawings,forming a part of this specification, and its structure will be fullyset forth in the following description, while the novelty of the invention will constitute the basis of the claims succeeding such description.
The invention, however, is not limited to the exact disclosure made by said drawings and description, for different variations as to several points may be adopted within the scope of the claims. I
Referring to said drawings, Figure 1 is a front elevation of a bar-cutter involving my invention. Fig. 2 is a transverse sectional elevation, and Fig. 3 a top plan view, of the same. Fig. 4 is a longitudinal sectional elevation of a portion of the cutter. Fig. 5 is a front elevation with the frame up.
Like characters refer to like parts throughout the several figures.
The cutter involves in its construction a main frame 2, which, as will hereinafter appear, carries a plurality of knives. This main be raised and lowered.
might be considered the rear of the vertical parallel strips 3,.rising from the front and rear, respectively, of the base-piece 4. From this it will be evident that the main frame can when down, it rests upon the upper sides of the strips 01' cleats 3. This main frame may be made from any suitable material and of any desired shape or size. Generally it is made from sheet metal of approximately rectangular form and carries on its under side a plurality of knives or blades 5, arranged in parallelism and equidistantly separated from each other. The length of these knives and the distance separating the same, as well as their number, are points that may be arranged to suit the taste of the individual users or of the work to which the cutter is put. These knives extend transversely across the opening of the main frame 2, and their ends are reduced and secured suitablysay by solderingto what might properly be considered the under side of the front and rear bars of. the main frame. I do not 5 rely wholly upon the solder connection between the knives and frame to hold the former in place. Passing under and in contact with the reduced ends of the knives are elongated f strips 6, the ends of which strips are soldered or otherwise connected to the under side of the frame and are similarly connected to the knives 5, by reason of whichthe latter are held securely in place.
An upright flange 7 extends completely around the wall of the opening in the main frame to receive the auxiliary frame 8, also shown as of rectangular form. The auxiliary frame 8, however, does not engage the said flange 7. Said auxiliary frame 8, which, as will hereinafter appear, carries clearers for the knives or blades 5, is carried by the main frame 2. For this purpose the main frame has centrally at its rear, or substantially, so a standard or post 9, to the upper end of which is'pivoted the elongated horizontally-disposed branch of an angular lever 10, the lever extending forward across the two frames 2 and 8 and the depending short branch thereof having a loop or eye 11 pivotally connected therewith, which loop or eye is adapted to receive the fingers or thumb for effecting the movement of the auxiliary or upper frame with respect to the main or lower one.
A cross-bar 12 extends across the upper or auxiliary frame 8 substantially midway be:
a movement relatively to the main frame 2.
The clearers for the knives or blades 5 are denoted by 14 and are disposed between said knives and also at the outsides of the end knives, although the clearers upon the outer ends of the knives are quite narrow. These clearers consist of elongated ,strips the lengths of which equal the effective lengths of the knives. The ends of the clearers or strips 5 have upwardly-disposed flanges, as 15, suitably secured, as by riveting, to the inner side of the auxiliary frame 8.
A series of pillars, as 16, is mounted upon the upper side of the main frame 2 in the vicinity of the corners thereof, such pillars being longitudinally bored and fittingbetween their ends in notches or recesses 17 formed in the horizontal outwardly-disposed marginal flange 18, extendingalong the top of the auxiliary frame 8, the pillars serving as effective guides for the auxiliary frame when the latter is reciprocated with respect to the main frame.
At the corners of the auxiliary frame 8-and extending outward therefrom are pins 19, which are shown as consisting of bolts the outer ends of which extend into the hollow pillars 16 through longitudinal slots in the latter.
The pillars 16 incase the coiled pull-springs 20, the lower ends of which are connected to the pins 19, while the upper ends of said coiled springs are connected to headed pins 22, the shanks of which fit in the upper portions of the pillars, while the heads thereof rest upon the tops of said pillars. The several springs yieldingly hold the auxiliary frame 8 in an elevated position with respect to the main frame, so as normally to maintain the clearers 14 in ineffective positions. When, however, the auxiliary frame 8 is thrust downward for a purpose that will hereinafter appear, the springs 20 are elongated, and when the thrust is withdrawn said springs will automatically return the auxiliary frame 8 to its initial position and the several clearers to their primary and inefiective positions.
To facilitate the raising and lowering of the main frame 2 and also the auxiliary frame 8, which is carried thereby, said frame has suitably attached to it the handle 23, which is shown as being of bail or yoke form.
Normally the clearers 14E are situated above the cutting edges of the knives 5.
The operation of the device is as follows: Fig cakes of any desirable number are taken from an oven after having been baked, and while hot and still in their pan are placed under the two frames 2 and 8, the latter prior to the placing of the pan having been elevated by the manipulation of the handle 23. The two frames are then lowered and pressure is applied to the lower frame to force the knives thereon through the cakes, cutting the same into bars of the proper size. The cakes are cut into bars while hot, so as to prevent them from crumbling when out. The machine cuts the cakes into bars accurately, effectively, and with rapidity. In fact, the operation of the machine can be carried on as fast as the material is supplied thereto. After the cakes or strips are cut into bars the main frame 2 is lifted, and simultaneously the auxiliary frame is depressed relatively thereto, so as to force the clearers 14 down to a line below the cutting edges of the knives, by virtue of which the bars or the stock cannot possibly adhere to said knives. The instant that the auxiliary frame 8 is released by the operator the coiled springs return said auxiliary frame, and hence the clearers, to their ineffective positions.
