FRICTION AND FLEXING APPARATUS FOR TESTING MATERIALS.
Specification of Letters Patent.
Patented June 22, 1920.
Application filed June 18, 1919. Serial No. 305,153.
v description.
This invention relates to improvements in apparatus employed in ascertaining the effect of friction or flexing or both upon ma terials, such, for example, as fabric, rubber, or the like. In the'use of the apparatus the material is subjected to the action of the apparatus for a definite length of time and is then removed and subjected to the action of a strength testing machine to ascertain the effect upon the fabric of the friction or flexing or both.
The invention will be understood by the accompanying drawings in which:
Figure 1 is a side elevation of. an apparatus embodying the improvements;
Fig. 2 is a fragmentary view, in perspective, and on an enlarged scale, illustrating the .fabric holding means; and
Fig. 3, is an enlarged .side elevation of the-fabric holding means when adapted for exerting friction alone upon the material.
The apparatus consists of a frame comprising the bed A, from which rise the\ standards a, the latter supporting cross members I), each cross member being formed with an apertured boss 0, for the purpose hereinafter described.
Slidably mounted in the body A is a plate B provided at one end with a suitable crosshead d-cl adapted to receive the end of a connecting rod E, said rod also being connected to acrank pin f on a drive wheel F By this means a reciprocating movement will be imparted to the plate B, and the parts carried'by it, upon the rotation of wheel F. j
Mounted upon-the plate B are blocks h, four of such blocks being shown, each being disposed immediately below pressure block '1' carried-by a rodJc. -Thesef1 ods are slidably mounted in the apertured bosses c, rotary movement of the rods 7: being prevented by set screws N engaging grooves or channels in the rods 70. The rods 76 are extended upwardly above the cross-members Z) and are adapted to receive weights V which rest upon plates M carried by the rods.
When it is desired to subject the fabric or other material to friction alone a piece of the material is secured to either one of the blocks h, i, and the slide plate B is reciprocated so that the material is subjected to a rubbing action between the two blocks under a pressure determined by the weight or weights carried by the supporting plate on. The material may be secured to the block by means of the pins p as shown in Fig. 3, or by any other suitable means such as the clamping frame 1* illustrated in the said figure in which the clamping pressure upon the fabric is regulated by means of a screw or screws t acting upon a movable block or blocks 0. In the said figure a piece of fabric is held by each block so that in the operation of the machine the two pieces offfabric are rubbed upon each other.
When it is desired to subject the material to flexing,"one end of a stri of material .may be impaled near one of its ends upon pins 1) projecting upwardly from each holding block 71, the material then being brought toward the opposite end of the block and folded backwardly, the folded end being clamped against one side face 'i' of the pressure block '2' by means of a clamping frame '7, the pressure of said clamping frame upon the material being effected by means of a set screw 8. The reciprocation of the plate B will then subject the material to a flexing action, and-by means of the weights this flexing action may be combined with a desired degree of friction or abrading action between the contacting faces of the material.
Having thus described my invention, what I claim and desire to protect by Letters Patent is:
1. An apparatus of the character described, superposed engaging members for the material to be treated, each member being adapted to hold one end of a folded piece of flexible material, means for moving one of said member-sin parallelism with a face of the material to subject the latter to .the last mentioned direction.
2. In apparatus of the character described, a reciprocable table, a bar slidably movable toward and from the table, opposed engaging members for the material to be treated, one member being carried by the table and the second member by the bar, each member being adapted to hold one end of a folded piece of flexible material, means for applying pressure to the bar, and means for reciprocating the table.
8. In apparatus of the character described, a table, a bar movable towardand from the table, two opposed members for holding the material to be treated, one member being supported by the bar and the second member by the table, means for applying pressure to the bar, means for reciprocating the table, and means whereby the pressure upon the bar may be adjusted.
4. In apparatus of the character de scribed, a frame, a table slidably mounted in said frame, a bar adapted for free end- Wise movement in said frame, means for moving said bar in one direction, means carried by the said bar and table for holding a folded piece of flexible material intermediate them, and means for reciprocating the table independently of the bar to subject the material to a flexing action.
