Application March 14, 1952, Serial N 0. 276,661

2 Claims. (01. 17-1) My invention relates to automatic means for stripping, or removing the outer casing from frankfurters, sausages, and the like; the instant application being an improvement over my copending patent application filed October 16, 1951, and designated Serial Number 251,484.

In the manufacture of frankfurters, sausages, and the like, which are stufied by a stuffing machine into artificial casings, the frankfurters are produced and manufactured in chain lengths each containing a multiple number of frankfurters. These lengths are fed into a casing stripping machine after they have been completely smoked, processed and treated as required, then they are fed into a machine such as is the basis of my invention, designated hereinabove. In order to automatically control the feeding of the last frankfurter of a chain of frankfurters, the stripping thereof, and also to automatically control the initial feeding of the first frankfurter in a chain or length of frankfurters, the improvement disclosed in this application is essential and mandatory.

It is therefore one object of my'invention to provide means for automatically controlling the operation of the guillotine means and the frankfurter splitting means, by electrical contact means introducedand connected in parallel in the existing circuit disclosed in the said copending application. I

Another object of my invention is to provide roller means, which will physically contact the contour of a chain or length of frankfurters being fed into the machine, the said roller means moving in accordance figuration of the frankfurters with the exception that the end of the last frankfurter will permit the roller to. break electrical contacts, thus opening the circuit torelease the-guillotine means to inoperative position, so as to permit the last-frankfurter to be fed through to the vacuum means for stripping the bisected sections of casing therefrom.

A further object of my invention is to provide yieldable electric contact means, which will maintain a closed circuit at all times that the said roller means is in physical contact with a peripheral portion of the chain or length of frankfurters, and will open the circuit hence breaking the said contact means when the roller with the peripheral coniii loses physical or intimate contact with the peripheral section of frankfurters.

A further object of my invention is to provide flexible contact means motivated by the said the chain or length of roller means to fluctuate in accordance with-the peripheral contour of the chain or lengthf'of frankfurters as it works in and outof the restricted portions between frankfurters, which will permit opening the circuit when the roller has been released from contact with the last frankfurter of the said chain or length of frankfurters; thus opening the circuit of the guillotine means, to permit continuous feeding to the ultimate stripping mechanism in the machine.

A still further object of my invention is to provide roller contact means resiliently urged into contacting relationship, and normally maintaining the electrical circuit open, so that when the initial end of the chain or length of frankfurters is to be fed into the machine, the said roller means will be motivated to close the said resilient contact means closing the circuit, so as to cooperate with the other electrical contact means on the casing splitting station to permit the automatic operation of the guillotine means, which is governed by the floating movement of the roller or guide in the said casing splitting station.

Other objects and advantages inherent in my invention will become apparent from an examination of the accompanying drawings, indicating to those familiar with the art the nature and the operation of the improvement over my copending patent application, and also depicting a simplified, modified structure for attaining the objects enumerated herebefore. The various elements comprising the foregoing improvement, are designated in the various views by like numerals, in which;

Fig. 1 is a schematic perspective view, showing the relationship of the electrical control means connected in series with the electrical control means indicated in my co-pending patent application.

Fig. 2 is a plan view of the improvement illustrated in Fig. 1.

Fig. 3 is a cross-sectional view taken, substantially, on the lines 33 of Fig. 2.

Fig. 4 is'a cross-sectional view taken, substantially, on the lines 4-4! of Fig. 3, and shows the flexing of the electrical contact means when the roller means is riding on the peripheral portion of a frankfurter in furters.

Fig.5 is a View similar to Fig. 4 showing the terminal portion of the last frankfurter of a chain or length of frankfurters being passed through the machine and showing how thecircult is open, also indicating in' phantom lines with parts broken away a chain or length of frank 3 the initial end of a subsequent chain or length of frankfurters to be fed into the machine to motivate the roller means to the operative position indicated in Fig. 4.

Referring to the various views, a chain or length of frankfurters I8 fed through guides I by the feed rolls 21 in the machine indicates the objects to be attained by the structural improvements contained or disclosed in this application, mainly, opening the circuit so as to relieve the guillotine means 64, of the electro-magnetic influence thereon through the circuit, through which its electro-magnetic elements are connected. The casing splitting station 63 is provided with an extended bracket portion I41, secured by screws I48 in order to support the electrical contact roller means I43, and permit connecting the same in series with the electrical contact means 91 and 99; the structural arrangement of the parts indicated in various views depicts a roller means I43, which is mounted in a fork element I42, which is rotatably mounted on the axle I in rolling arrangement, so as to permit it to roll about the peripheral contour of the chain or length of frankfurters I8, so that the same will ride on the outer surface of the frankfurters, or fall into the depression resulting from the constriction I44 of the casing at various points to define individual lengths of frankiurters.

The frankfurter guide It is, preferably, broken at MI in order to provide a clearance opening for the roller means I43, to be motivated inwardly and outwardly as the frankfurters are fed thereby.

The fork element I42 is provided stem encircled by the resilient or spring element I46, abutting the bracket I41, the reduced stem terminating in a head portion I49, which is in intimate contact with the electrical terminal I5il, through the spherical insulating button I55, so as to permit equalization and equalized action when the roller means I43 is moved inwardly and outwardly, in order that the terminals I513 and I52, which are connected by insulating material I5I, may be flexed to the position I59 of Figs. 2, 4 and 5, to operate within that range of flexure depending on the position of the roller means I43 as it traverses the peripheral portions of the chain or length of frankfurters I8.

The electrical contact terminals I and I52 are provided with contact points I53 and I54, respectively, and when the contact is broken at I58 as indicated in Fig, 5, the said condition occurs only when the roller means I43 is urged to its maximum position by virtue of the fact that it loses its support on the contour of the frankiurters, inasmuch as the terminal portion I40 having passed the same, the circuit is opened or broken so that the guillotine means 64 will be released to normal position and permit the last franki'urter to continue in its passage through the stripping station, which by means of pressure and evacuation will strip the bisected sections of casing material from the last frankfurter.

Likewise the introduction of a subsequent chain or length of irankfurters I8, by virtue of the initial terminal portion I coming into intimate contact with the roller means I43, will compress the spring I46 sothat the same will be moved outwardly sufficiently to close the gap I58 and continue to flex the terminals I50, i52 without contact therebetween being broken, inasinuch as "the said terminals are connected by with a reduced fail means of leads I56, I51 to contact 91, and to the

electric leads

65 and 66, connecting the same in series with the circuit of the guillotine means as formerly connected to the contacts, 91 and 99. Thus as the frankfurters are passed through the machine the make and break contacts 91 and 99 will automatically control the guillotine means 64, as is disclosed in my co-pending application, yet when the terminal portion I4t passes and allows the contacts 91 and 99 to remain closed, without opening the said contacts, the guillotine means would also remain in a closed position inasmuch as the electro-magnets would remain energized, thus militating against the continued feeding and passage of the last frankfurter through the feeding rolls to the casing stripping station; thus by the addition of the auxiliary electrical contact means comprising the roller contact means I43 and its cooperative organization with the terminals I56 and I52, the circuit will be broken Whenever the last franki'urter is fed through as indicated in Fig. 5, and the circuit will be closed once again when the initial portion E69 of a subsequent length or chain of irankiurters is to be fed through the machine.

It is to be noted in the arrangement indicated in Figs. 1 and 2 that the casing splitting station 53 and the guillotine means 54 are preferably spaced apart the exact length of one frankfurter, so that when the contact 91 rides into a depression or constriction between frankfurters, the guillotine will be actuated one frankfurter immediately ahead thereof, and likewise the auxiliary roller contact means I43 will be actuated to open the circuit of the guillotine means when the contact means 91 andxsfi is closed because there is no succeeding frankfurter to lift the contact 91 from the contact 99 and break the circuit.

Although the drawings and the above specification disclose the best modes in which I have contemplated embodying my invention, I desire to be in no way limited to the details of such disclosure, for in the further practical application of my invention many changes in the form and construction thereof may be made as circumstances require or experience suggests without departing from the spirit of the invention as expounded within the scope of the appended claims.

Having thus disclosed and revealed my invention, what I claim as new and desire to secure by Letters Patent is:
