TRIPE WASHER l Filed June 22, 1937 Patented May 31, 1938 TRIPE` WASHER Oscar Biedermann, Chicago, Ill., assigner to The Globe Company, Chicago, Ill., a corporation of Illinois Application June 22, 1937, Serial No. 149,711

8 Claims.

This invention relates to tripe washers. Washers of the character forming the subject matter of this specification are used. for washing and scrubbing tripe and similar articles of food.

Heretofore a rotatory or oscillatory cylinder or drum has been employed for this purpose, and the scrubbing .wall thereof usually was formed with a multiplicity of holes, surrounded by inwardly struck-up burrs, the edges of which were rough and served to wear away olensive matter from the tripe as it tumbled about in the rotatory or oscillatory cylinder. The cylinder rotated or oscillated in a tub containing water, soda or some other cleansing substance which entered the cylinder through the holes in its scrubbing wall and washed away the foreign matter.

The main difliculty with cylinders of this construction, has been that the burrs wear away rapidly and after the machine has been in use for a relatively short time the cylinder must be replaced. This adds greatly to the cost of processing the tripe and often the cylinder must be discarded, although many of the burrs are still in a fairly good condition for use.

The principal object of the present invention is to provide removable and replaceable burrs for the cylinder, whereby when any of them become worn down so as to be practically useless, the worn burrs may be removed from the cylinder and replaced by new ones, thereby enabling the cylinder to be used for an indenite length of time.

Another object is to provide burrs for the cylinders of tripe Washers, which may be easily and quickly removed from the cylinder and replaced by new ones.

With these and other objects and advantages in view, this invention consists in the several novel features hereinafter fully set forth and claimed.

The invention is clearly illustrated in the drawing accompanying this specification, inwhich:-

Fig. 1 is a side elevation, partly broken out, of a tripe washer, embodying a simple form of the present invention;

Fig. 2 is a side elevation of the cylinder, partly broken away;

Fig. 3 is an enlarged, fragmental plan of the cylinder scrubbing wall showing one of the burrs secured therein;

Fig. 4 is a vertical, longitudinal section, taken on the linev 4-4 of Fig. 3, and

Fig. 5 is an enlarged central section through a slightly modified form of burr.

Referring to said drawing, the reference character 5 indicates the tuloL of a standard make of tripe washer, usually in the form of a semi-cylindrical tub, mounted on legs at each end, two or" which are shown at 6. Rising from the rear part of the tub is a stationary cover l, which leaves 5 an opening at the front, that is closed by a movable cover 8. Desirably the tub is reenforced by a frame 9. A discharge trough I 0 is usually provided at the bottom of the tub, which is controlled by a valve or gate (not shown) operated by a lever II.

Rotatively mounted in the tub is a container l2 for the material to be washed. It is shown in the form of a cylinder composed of end walls I3, connected by a scrubbing wall I4. Stub shafts, one of which is seen at I5, are secured to the end walls of the cylinder, and are journaled in bearings carried by the frame. Means are provided to rotate or oscillate the cylinder, the means shown comprising a Wheel or pulley I6 mounted on one of the shafts, a wheel or pulley l'I, driven by an electric motor I8, and a belt IB trained around the wheels or pulleys. The motor is mounted on a frame 2U carried by the tub or its stationary cover. The driving means shown serves to rotate the cylinder in the tub.

The scrubbing wall I4 is usually made of sheet metal, and may take various shapes. It may be cylindrical or many sided, and it is here shown as formed of concavo-convex sections 2|, secured upon rods 22, fastened to the end walls. The convex faces of the sections 2I form the internal faces of the scrubbing wall, in the form of the invention sli-own. The section 23 closes an opening 24, in the scrubbing wall, through which the material to be washed is placed in the cylinder and through which the cleaned material is removed. The section 23 may be hinged to the rod 22, at one side of the opening, and is provided with a latch 25 for locking it to the rod 22 at the other side of the opening. These parts are common and well known and require no further description so far as this specification is concerned.

In the several sections of the scrubbing wall, holes 26 are punched, and in said holes are secured removable and replaceable burrs 2l, which proj ect into the interior of the cylinder. As shown, the burrs are in the form of sheet metal stampings, struck up with suitable dies. Desirably the burrs are of ring like or annular form, having a cylindrical web 28, which projects laterally from the outer margin of a round flat web 29, and a cylindrical web 30, which projects laterally in the opposite direction from the inner margin of the web 29. The cylindrical web 28 projects into the interior of the cylinder, and its edge is roughened, serrated or otherwise shaped to enable the burr to operate on the tripe with an abrading action, asthe latter tumbles about in the cylinder. As shown, the edge portion of the cylindrical web 28 is struck up outwardly to form a multiplicity of scallops 3|, the lower ends of which merge into the cylindrical part of the web. The edges of the scallops and of the cylindrical parts therebetween, provide variously directed abrading edges, thereby greatly increasing the efliciency of the burr.

The round web 29 lies flush with the inner face of the scrubbing wall, and the cylindrical web 30 projects through the hole 26, and has its edge portion 32 clenched upon or beaded over the metal of the scrubbing wall adjacent the hole. Desirably the burrs are secured tothe scrubbing wall by means of a suitable tool or die. In case a burr becomes worn down to such an extent that it does Anot functionY properly, Vthe beaded part 32 is collapsed, vpermitting the burr to be removed and replaced by a new one.

In the modified form of burr illustrated in Fig. 5, the burr 2la is formed with the cylindrical web 28a, the round flatweb 29B and the smaller cylindrical web 30a, as in the preferred form, but the scrubbing edge of the burr is serrated as shown at Sla. In other respects the burr is similar to the one heretofore described and is attached to the cylinder in the same manner.

In the operation of the washer, the tub is filled, orpartially filled with water and cleansing material and the tripe or other material is placed on vthe cylinder and the latter operated lin the usual manner.

yBy reason of the scalloped abrading edges of the burrs, a more eflicient abrading action is ob tained on the material and there is no likelihood of its'being injured, as is the case when the ordinary burrs are used. Moreover, the burrs may be made from non-corrosive material, having good wearing properties, thereby prolonging their usefulness far beyondthat of the ordinary burrsthat are struck up from the material of the scrubbing Wall.

Iclaim yas new and desire to secure by Letters Patent:
