APPARATUS FOR CUTTING SOAP INTO BARS.

- Application filed April 3, 1922. Serial No. 549,313.

. To all whom it may concern:

Be it known that I, JULIUS A. SGHWANTES, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Apparatus for. Cutting Soap into Bars, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to an electrically operated device for cutting soap into bars which is preliminary to a further operation whereby they are cut into cakes.

This invention has for its object to provide a device of this type which will automatically sever the continuous bar of soap fed through the device into pieces of the proper length, the device being furthermore capable of adjustment whereby the length of the pieces cut may be varied within certain limits.

With this object in mind the invention consists in the novel construction and arrangement of parts which will hereinafter be more fully described and illustrated.

In the drawings- Figure 1 is a side elevation of a portion of a machine for forming the soap in a continuous rectangular bar,,with this improved invention attached thereto.

Fig. 2 is an end view of the attachment.

Fig. 3 is "an enlarged longitudinal section taken on the plane indicated by line 3-3 of Fig. 2. I

Fig. 4 is a diagrammatic view of the'electrical connections employed.

Referring now more particularly to the drawings wherein like reference characters represent like parts, the reference character 10 designates a portion of a machine for forming the soap into a continuous rectangular bar, which is ejected from the end thereof onto the support composed of rollers 11. v

. Referring to Fig. 2 wherein the discharge opening of the. machine 10 is indicated by the reference character 12, the position of the device'forming the subject matter of this present invention will be disclosed. Secured core 17.

adjacent the discharge opening 12 (see also Fig. 3) is a frame 13 providedwith bearing members 14 which slidably support bars 15.

Also secured to the machine .10 are two solenolds 16 provided with iron cores 17, the windings of the solenoid being indicated at .18. The iron cores 17 are extended through the end of the solenoid 16 and have mounted thereon coiled springs 19 which engage on one hand against the end of the solenoid 16, and on the other hand against a cap or the like 20 secured to the outer end of the The other end of each core 17 is provided with a head 21 formed with an inclined bear ing surface which engages'aroller 22 rota-- tably mounted on the adjacent end of the bar 15. A spring 23 connected respectively to the core 17 and the bar 15 keeps the rolle 22 in engagement with the head 21. I

To the end of each bar 15 adjacent the discharge opening 12 of the soap machine there is pivotally journaled a knife 24, the pivot shaft of which carries a coiled spring 25 which tends to holdthe knife 24 in the position illustrated in Fig. 3, that is in-engagement with a projection 26 formed onthe bar 15. The pivoted knives when operated funcframe 13 are positioned adjacent the sides of the discharge opening 12, whereby the ejection of the bar of soap is facilitated.

The, knives 24 will be drawn toward one another to sever the bar of soap into pieces of suitable length when the solenoidwindings 18 are energized and the cores 17 longitudinally displaced. For accomplishing this there is provided a control device comprising a bar 29 pivoted to the arm 30 at 31.

bar carries a stationary contact 32 eninto its path of travel.

gageable by a contact 33 carried by a pivoted arm 34. The pivoted arm 34 projects upwardly into the path of the bar of soap S. A coiled spring 35 maintains the pivoted arm 34 in its spaced position. The lower end of the pivoted bar 29 has a sliding corn tact, as at 36, with a terminal member 37 to which one of the circuit wires 38 is connected. The circuit therefore is maintained as longas the sliding Contact 36 engages the terminal member 37 and the circuit will be broken when this member slides off the. end of the terminal member 37. The pivoted lever 29 is rocked by engagement of the bar of soap with the arm 34 which projects The other circuit wire is indicated by the reference character '39.-

The switch members thus far described are the auxiliary or supplemental switches -=aiid control the current to the main switch 'gized while theysoap is being out.

which is contained in the oil tank 40. The

switch arm. 41 pivoted therein is attracted by an electromagnet 42 whereupon the contacts 43 -are closed, these contacts being immersed in oil. is energized and the contacts '43 closed thehen the electromagnet 42 circuit to the solenoids 16 will be complete and the knives 24'moved to cut thebar of soap. Connection witha suitable source of current may be controlled by ahand switch broken when the sliding contact 36 moves off 'the terminal member 37 When the contact ' members 32 and 33 engage, the electromagnet 42 is energi-zedand remains ener' When the contacts 36 and 37 are disengaged, the circuit to the'magnet42 is broken and hence the springs are'rpermitted to return the knives or blades to their original position.

By providing means for energizing the magnet which holds the main switch closed, theoper'ation of the knives does not depend solely upon a continued engagement of the contacts 32 and 33.

For-regulating the length f the pieces of soap to be out the arm 30 is adjustably supported in a bracket45' depending from 'the machine. The adjusting bolt 46 thre'aded into the end of the arm 30 enables the same tobe'moved horizontally thereby positioning the arm 34 variable distances from the' discharge' opening 12 of the soap machine. Therefore, the time at which the "end of thebar of soap engages the switch arm 34 maybe regulated.

"In practice after the bar of soap has been cut'fiinto pieces of the desired length it is removed from the machine and out into smaller cakes by means of wire cutters. Obviously, therefore, the size of the pieces of soap cut by this device must be accurately gauged so that the smaller cakes out by the wire cutters will be uniform.

While one constructional example of this invention is illustratedherein'it is not intended to limit this invention to the details of construction shown, but reservation is hereby made to make such changes and modifications as may come within the purview of the accompanying claims.
