Specification of Letters Patent.

Patented Nov. 16, 1909.

Application ma Inch 10, 1909. Serial Io. 482,480.

To all whom it may concem:

Be it known that I, HENRY L. Soon, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Testers, of which the following is a specification.

My invention relates to testers, that is machines pur sad to test the stress sustainable by arns, c 0th, and other articles.

l he essential objects of the invention are sim licity, com actness, and strength. Also uni ormi an accuracy of operation and results. urther to facilitate operation upon cloth or other fa rics.

To the above-ends essentially my invention consists in the novel construction, combinntion and mode of o eration of parts set forth in and falling wit in the scope of the claims hereto appended.

In the drawn which accompany and form a. part of t specification, F igure 1 is a side elevation of my novel tester, Fig. 2, a front elevation of the same omitting for perspicnity the r case, Fi 3, a section of the machine on 'ne a: n: of g. 2, Fig. 4, a front elevation of the upper portion of the machine with the dial removed. Fig. 5, a. detail view of the drum and adjacent parts, Fi 6 7,-perspective views of the upper sin lower clamping members respectively, and Fig. 8, a detail view of the pointer, segment, and inion.

Like re erence numerals parts throughout the views.

In its present embodiment my machine comprises a back board, 1, to whose upper end is fixed a. suspension ring, 3. Upon the face of the board are fixed by nuts, el and 5, horizontal arms or plates, 6 and 7, whose outer ends are connected by a vertical plate, 8. A second plate. 9, in the rear of and parallel with the date, 8 is integral with plates 6 and 7. ll-otntnbly mounted upon pivot points, 10 and 11, in plates 8 and 9 respectively is a drum, 13. provided with an annular move, 14. near its forward end. and :1 lm or axial projection, 15. which is engaged by the pivot point, 10. Fixed by mzrews, Ill and 1.7, 10 projections, 18 and HI. upon the plnlc, 8. is a dial pinto, 10, provided with marginal grnduntions. 2|; upon its 'l'acv indii-uliug pounds from 0 to 200.

llolnlnbly mounted in the plul'v. 8. is n piullo, 2R, cxlmuliug lhl'ougll the router ol the dial, 21, carrying upon its outur cud n indicate like pointer, 25, and upon its inner end a pinion, 26, which meshes with a. toothed segment, 27, fixed to the hub, 15, of the drum.

s iral spring, 28, is fixed at its inner end to t e pintle and at its outer end to a. pin. 29, in the fplate, 8. Integral with therear portion 0 the drum, 13, is a lever arm, 31, to which is fixed intermediate its length a wei ht, 32, and to whose free end is pivoti a pawl, 34, having intermediate its len h a pin, 35. This pawl engages the teat 36, of a curved rack, 37, fixed by screws, 38 and 39, to studs, 40, and 41, to the back board.

Upon the lower rtion of the back board is a bracket, 42, .astened b a screw, 43. This bracket may be inclo when desired by a gear casing, 44. An operating spindle, 45, has its upper end in an opening, 46, in the plate, 7, while its lower portion has a.- bearmg as at 47, in the upper portion of the bracket. The spindle is provided intermediate its length with a screw thread, 49, and. has fixed to its lower end a bevel gear, '50, which meshes with a second bevel gear. 51, upon the end of a shaft, 52, mounted in a. sleeve, 53, integral with the bracket. Upon the end of the shaft, 52, is a hand wheel, 54, for driving the shaft, 51, and connected parts. It will be understood that the shaft, 51, may be driven by any convenient power means such, for instance, as the power attachment described in my pending application Ser. No. 477,552.

Fixed to rojections 56 and 57, u on the plate, 7, 111 bracket, 42, respective y, and concentric with but interspaccd from the spindle, 45, is a tube, 58, provided with a longitudinal slot, 59. Within the tube is u not or sleeve, 60, provided with internal threads, 61, which loosely engage the threads, 49, of the spindle. 'lhis sleeve is integral with n plate, (52, which passes through the slot, on. Integral with the end of the plate or web, 02, is n clamping plain or jaw, 63, which has upon its lower portion a lateral lug, (34, in wlnch is It pin, lib, upon which is hinged a second clamping jaw, (37. Fixed by scrmvs, (i8 and (it), to the jaws, (ill, and (ii, are hearing plates, T0 and 71, res actively. 'lho i-lniuiing plates are provulml inlurun-dintr their length with lln'unded openings, Til and 7-1, to ll'lJFlW! n clumpin screw. 76, provided wilh a handle, 76. Fixed lo the upper portion of lho tube, 58, by it screw, 78, or otherwise is an arm, 80, in

:2 house whose end is slidabl mounted a vertical rod, 81, having fixe to its lower end a clamping jaw, 82, provided with a threaded opening, 83, and having fixed to its margin by screws, 84, a bearing plate, 85. The ]aw is rovided at its base wit-h a lug, 86, to winch is hinged by a pin, 87, a compan on jaw, 89, in which is mounted a clampm screw, 91, which enters the opening, 83, an is provided with a handle, 92. A clamping plate, 93 is fixed to a plate, 89, by screws, 94. Attached to the upper end of the rod, 81, is a chain or other flexible member, 96, having its other end fixed by a pin, 97, in the channel or groove, 14, of the drum.

The operation of m machine is as follows: The material to be tested is placed in the u )er and lower clamping jaws and enage tween the bearing faces thereof by t eir screws 75 and 91. The shaft, 52, 1s then rotated, which through the gear 51 and 50, rotates the spindle, 45, thus sli in" the sleeve, downwardly upon the thread ed portion oi the same thus exertin an increasing tension upon the lnateria under test, pulling downwurdl the rod, 81, rotating the drur'n, 13, and iorcing the weighted arm, 31, from its normal vertical position in the direction of an arc. The movement of the drum is communicated through the segment, 2?, pinion, 26, and pintle, 23, to the inter, 25, which indicated it n the a nation, 21, the number of can stress iug undergone by the sump e. The moment that the material is rent the pawl, 35, engages a tooth of the rack, 37, by which it is prevented from violent return to original position. The winter, 25, thereupon returns to origina position under the action of its spring], 28.
