'roNGUE-SWITCH. I

Patented March 3, 1908.

Application filed November 27, 1907. Serial No. 404,094.

To all whom t may concern.'

Be it known that I, VICTOR ANGERER, a citizen of the United States, residing in Ridley Park, Pennsylvania, have invented certain Improvements in Tongue-Switches, of

which the following is a specication.

The object of my invention is to so arrange a pivoted tongue switch that the bearing for the pivot of the tongue can be readily re- .moved or adjusted as desired, and yet when and Fig. 6, is a perspective view of the base plate.

A is the body of the switch structure made preferably of manganese steel. The body has projections a, a and a2 to which the rails of the track are coupled in the ordinary manner.

B is the tongue ofthe switch adapted to be moved either against the rail Harige c or the guard liange c of the switch structure; this tongue B has a downwardly extending pivot b at its extreme rear end as indicated in Fig. 2.

In the body of the switch structure A is a cavity C containing-a base plate F and an annular bearing E for the pivot 2') of the switch tongue. The base plate F, which is preferably quadrangular is shape, as shown in Fig. 6, is slipped into place through a slot in the rear wall of the cavity, and the bearing E is placed in position from above. The cavity is much larger than the annular bearing E so as to allowthe bearing to be inserted in the cavity and then pushed under the overhanging port-ion (L3 of the body A, Fig. 3.

When the body of the switch structure is made of manganese steel. itis practically impossible to make a smooth iinish for anyQpart used as a bearing, owing to the hardness of the metal, and by. mounting the-parts E and F within the switch structure I am enabled t6 provide a smooth surface for the-pivot of the switch ton ue. The annular bearing E can be adjuste and held in its adjusted position by set screws 'i which are screwed into the casing surrounding the cavity and on these screws are locking nuts i which hold them in` position after adjustment. In order to rovide a suitable seat for thejbase plate. I pour molten metal, as indicated at :15, between the plate and the bottom of the manganese casting and I also pour molten metal, as indicated at a, between the annular bearing and the sides of the cavity, which will close the openings against the accumulation of dirt andwill hold the set screws rigidly in osition. As there is considerable space in ront ofthe bearing to allow of its withdrawal from under the overh angingortion a3, I usually place a block of metal in this space to act as a filler in place of the molten metal. j

When it is desired to remove the bearing E after it becomes worn or injured, I simply remove the metal a." and the block I, back off the set screws i and slide the bearing forward until it is clear of the overhanging portion a3, when it can be readily removed and a new one substituted for it if desired. The annu- 'y lar bearing E is adjusted and held by the setscrews and it need not be adjusted againunless the parts become worn, or its is desired to remove the bearing. Thus it will'be seen that I can make the body of the switch structure of hard metal, such as manganese steel, and have a neatitting bearing for the switchA tongue so that no material can accumulate around the pivot of the switch tongue. The partsv can be readily assembled and removed, as desired, and yet when in position Will'vbe absolutely rigid.

1. The combination of a body portionvo'Il a switch structure, having a cavity, an annular bearing mounted in the cavity, set screws for adjusting the bearing, and a switch tongue mounted in the bearing.

I2. The combination in the body portion of Y a switch structure, having a cavity and a portion overhanging the cavity, of an annular bearing mounted in the cavity under the overhanging portion, said cavity being of such a size that the bearing can be moved Jfrom under the cavity and withdrawn when desired, means for retaining the bearing in tlie cavity, and a switch tongue having a pivot adapted to the bearin l f 3'. The combination of a ody ortion of a switch structurehaving a cavity t erein open at the top and at the rear, a base plate adallt ed to be inserted in the cavity through t e means for retaining the bearing in position, and a switch ton 'ue having a pivot ada ted. to the bearing an restin upon the base p ate. 4. The combination o a body portion of a switch structure, having a oavitytherein, 'a base plate mounted in the bottom of the c avity, an annular bearingv mounted upon the base late also Within the cavity, set screws for a justing the annular bearing Within the cavity, and soft metal lling the interstices between the 'bearing and the plate and the body of' the switch structure, with aV tongue having a pivot adapted to the bearing.

5. The combination of a body portion of a x switch structure having a cavity yat one end ening in the rear, an annular bearing adapty to be inserted in the cavity from the top,.

and a switch tongue having a pivot mounted in the bearing. v

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing Witnesses.
