Application filed May 12. 1897. Berialllo. 686,131- (No modeld To all whom it may concern:
Be it known that we, JOHN HENRY SWI` HART and EMUND R. CROSS, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain Anew and useful Improve marketable scale the platformniust restsquarely upon the subplatform, and it must also be prevented from moving horizontally relative thereto. Heretofore the rcontacting surfaces of thetwo platforms have been filed -or ground down until they fitted each other so accurately that the platform can have no rocking motion, and thehorizontal movement of the platform has been prevented by other means--viz.,V by vertical pins formed on the subplatform which enter corresponding holes in the platform.
One object of our invention is to provide simple and novel means for effectingr both of ther` .a desirable'results. i f' Another object is to provide a more or less i yielding cushion between the platform and the subplatform for the purpose, primarily, of 'relieving the shock upon the knife-edges which support thevsubplatform when a weight is placed suddenly uponl the platform.
The invention consists in the construction and combination of parts hereinafter described and claimed. l f
In thedrawings, Figure l is a plan viewof a subplatform of a scale embodying our invention. Fig. 2 is a vertical section of the platform and subplatform and one of the adjustable leveling and retaining pins which are carried lby the subplatform and upon which the platt'ormrests, and Fig. 3 is a similar `view of a modified construction. y
.A represents thefsubplatfornx, which may be merelya cast-iron frame. At the four bearing-b1ocks a, and these bearing-blocks.y
rest upon knife-edge bearingsG, which 'are carried by the platform-levers g.
B B represent vertical pins, which arecon nearly in line with and above 'the several should be vertically adjustable. I
C represents the platform,which` may *be corners of thesubplatform and morel'or less bearings blocks, and at 'least one 'of them made of rany suitablemat'erial; This plat- 'form rests upon the pins B. lInthe bottom placed that they will receive the pins B. The pins therefore support the platform, and
'because of their vertical adjustability they are the means to level the platform, and they'- likewise prevent its movement horizontally relative to the subplatform."V
of the platform are holes c, which-fare so The construction. ofthe pins wherebythey are vertically adjustable may be varied to a considerable extent without departure from pins are threaded and'they screw into holes in the subplatform. lThe platform is supported by resting upon the upper ends of said pins, which ends enterthe holes c. In Fig. 3j
the lower4 end of the pin is threaded and passes loosely through a hole in the subplatl form, and a nut-c' screws onto its lower end below the platform. Above tle platform, but below its upper end, the pin is provided and the suhplatform may be placed one or more washers or shims D, whereby the flange is elevated more or lesslabove the subplatform. When'the nut is tightened, the pin becomes limmovable 'relative to the subplatform. :In this construction the upper ends of the pins enter the -holes in the platform,
.85 with anannular flange b. Between thisflangev but fit loosely therein and do nottouch the ends of the holes,.the platformbeing supported upon the flanges. fAs before stated, it is not necessary to have all of these leveling and retaining pins adjustable. If one of 5 vcorners are depending legs a', which carry 7s i' the in vention-as, for example, in Fig. 2 the while the platform is supported by the pins. The second part of the invention relates to the intel-position of a yielding cushion be tween the platform and subplatform to relieve the shock upon the knife edges when a weight is thrown on the platform. This improvement is shown in severalforms in the drawings. In Fig. 2 a rubber cap E embraces the leveling-pin and enters the hole in the platform, the platform resting directly upon this cap. In Fig. 3 a-rubber washerE is in terposed between the fiange b and base, and' theplatform rests upon this Washer. The cap andthe washer both actas yielding cushions interposed between the platform and subplattorm and effect the results stated. Although rubber cushions are shown and described, any other form of spring-cushion may be employed.
Having described our invention, We'claiml. Ina platform-scale, the combination of the platform-levers, a subplatform resting thereon, vertical pins secured to said sub# platform, each having a horizontal flange above the subplatform-one of said pins being vertically adjustable-with a platform which is supported upon said flanges, and has holes into which the upper ends of the pins project loosely, substantially as described.
L2. Ina platform-scale, the combination of a subplatform having a plurality of vertical pins near its corners, at least one of said pins being constructed and combined with the subplatform as follows, said pin having between its ends and above the subplatform a horizontal flange, and having its lower end threaded, said lower end passing through the subplatform, a nut screwed onto the lower end of the pin below the snbplatform, and oneor more washersinterposed between the subplatform and flange, with a platform supported upon the pins, and having holes into which the pins project, substantially as described.
j In either case the pins being -above are supported by the subplatform,
667,141Qv A 3. In a platform-scale, the combination of a subplatform,^a leveling-pin secured to said 'subpla'tforrn having a .flange between its ends and above the subplatform, and a threaded lower end which passes through the subplatform, a nut screwed onto said lower end belowthe platform', and one-or more washers between the flange and subplatform, with a platform, one corner of which rests upon said iiange, and has a hole which loosely receives the upper end of said pin, substantially as described.
4. In a platform-scale, the combination of the platform -levers, a subplatform resting.
thereon having a plurality of vertical leveling-pins, a platform whichis supported upon said p ins, and yielding cushions interposed between the pins and platform,,substantially as described. l
5.V 'In a platforin-scale, the combination of .the platform-levers, a subplatform resting thereonV and a platform,.a plurality of vertical leveling-pins which are secured to one of said parts and loosely enter holes in the other part, and yielding cushions interposed between the pins and that member to which the pins are not positively attached, substantially as described.
.cally adjustable and is provided witha flange above the subplatform, a platform, and rubber cushions interposed between the platform and pins, the cushions associated with the adjustable .pins being washers which rest upon the flanges thereof, substantially as described.
