F. H, BENJAMIN SURFACE TESTER Filed Aug. 3, 1935 INVENTQR.

f/VJAM/A/ Hem /1 BY ATTORNEY.

' anism as a unit on the base 2l.

Patented Apr. 5, 1938 UNITED STATES PATENT OFFICE 2 Claims.

My invention relates to novel apparatus for testing the surface wear of a fibrous material, and more specifically relates to a novel jute liner surface tester or scui tester.

Objects of my invention are to provide novel apparatus for testing the surface of fibrous material which is inexpensive, simple and accurate; and a novel jute liner surface tester.

There are other objects of my invention which together with the foregoing will appear in the detailed description which isl to follow in connection with the drawing, in which:

Figure 1 is a sectional side View on line I-I of Figure 2.

Figure 2 is a plan View.

Figure 3 is a sectional View on line 3-3 of Figure 1.

Referring to Figure l, a rectangular block 5 of convenient dimensions around which the paper P desired to be tested is wrapped in a manner to permit the ends of the paper to overlap under the lower face of block 5 so that when the said block is forced into the frame F, the paper is held thereon securely.

As shown in Figures 1 and 2, the block 5 fits snugly between the end blocks 6 and 'I of the frame, which are mounted on the base 8.

A slidable upper block 9 of considerably smaller dimensions than the lower block 5 is used to carry a similar surface of paper P on its periphery and' is held tightly by a plug type member IIII which ts snugly in the cut-out formed in the block 9.

In the center of the plug-block I0 a longitudinal slot as at II is cut-out to permit the semicircular head I2 of support I3 to enter and freely rotate therein. A platform I4 carrying a Weight I5 is mounted on. the support I3. EX- tending from the platform I4, a tie-rod I6 of any desired shape and length serves as the crank rod for the crank pin I1 which is mounted on the rotating plate I8. The plate I8 is driven through the reduction gear box I9 by the motor M, which is mounted together with the reduction mech- As will be seen in Figure 1, the crank pin will cause the platform I4 to have reciprocating motion carrying with it the support I3 and block 9 on which the paper is wrapped (as indicated in dotted lines) thus producing the desired friction of the paper P' upon P. The block 9 is guided`- between two guides 22 and 23.

While I have shown a specific mode of carrying out my invention, it must be understood that this may be departed from Without departing from the scope or spirit of my invention, and I do not intend to be limited except by the following claims.

I claim:

1. An apparatus for testing paper manufacture which comprises a frame, a removable block adapted to be held securely in place by said frame and adapted to have a layer of the material to be tested overlapping the under surface of said block to be secured thereto, said frame comprising a pair of members engaging said block and securing said paper thereto, a second.i block for carrying a second layer of material to be tested, a removable plug seated in said second block for securing said second layer of material to said second block, said plug having a slot therein, a head seated downwardly in said slot for free rotation therein, a platform carrying a weight for maintaining said head seated in said slot, a bellcrank, a tie-rod connecting said platform to said bellcrank and a motor for driving said bellcrank.

2. An apparatus for testing paper manufacture which comprises a frame, a removable block adapted to be held securely in place by said frame and adapted'A to have a layer of the material to be tested overlapping the under surface of said block to be secured thereto, said frame comprising a pair of members engaging said block and securing said paper thereto, a second block for carrying a second layer of material to be tested, a removable plug seated in said second block for securing said second layer of material to saidsecond block, said plug having a slot therein, a head seated downwardly in said slot for free rotationy therein, a platform carrying a Weight for maintaining said head seated in said slot, and means including a motor for reciprocating said platform.
