Specification of Letters Patent.

Patented Aug. 21, 1917.

Application filed September 16, 1915. Serial No. 50,952.

To'aZZ whom t may concern.'

Be it known that I,.FRANK S. HEBBEN, a citizen of the United States, residing at Chicago, in the county ofA Cook and State of Illinois, have invented certain new and useful Improvements in Scales, of which the following is a specification.

My invention relates to cially to a scale 'adapted' to other substances while in ment over a scale member.

My present invention is an improvement over my invention exhibited in Letters Patent No. 1,073,072, issued September 7, 1913, and reference is made to said patent for announcement of the general principles and plan of operation of devices of this charscales and espeweigh gram and translt or moveacter.

My present-invention has special reference to means of transmission from a driven carrying member of lateral movement occasioned by varying weights of materials being carried thereon; to special means for transmission of said movement to registering mechanism; to special means for supporting the'carrying member, and to detail parts and combinations thereof hereinafter ture and the supplemental frame structure connected therewith, together with parts supported therein and showing a disk member in section; Fig. 5 is a sectional view on line aa of -Fig. 4;

Fig. 6 is a detail viewshowing correlated disk members and means for supporting and guiding one of said members;

Fig. 7 is a sectional view of a depressible supporting member for draper belt;

l Fig. 8 is a sectional view on the line b*b of Fig. 2 and v Fig. 9 is a detail view of correlated disk members, one of said members being broken away. y

In carrying out myy invention, I have said draper planned to properly support a traveling ele.- ment, as for instance, a belt or draper in a manner adapted to receive the flow of grain or other material from a substantially contInuous source of supply and to drive said belt from a suitable source of power, and to this end I have provided a rectangular base frame support 2, vertical standards 3 and 4, the latter supporting respectively roller members and 6 fixed respectively upon shafts 7 and 8,- said roller members carrying a belt or draper member 9. I have illustrated in a diagrammatic manner a chute or spout 10 for the purpose of indicating a means of discharge from the supply source of materialsto the draper member 9. 1l is a belt wheel fixed to shaft 7 and is driven from belt l2. The upper reach of the draper member9 is supported at its receiving end upon roller members 13, the latter in turn supported upon standards l-fl upon cross or connecting member 15, and at its outer end upon roller 16 supported upon standard 17. Intermediate' the support of member upon roller members 13 and 16, I have provided a depressible support, the latter comprising roller members 18 and 19 supported respectively in framing members 20 and 21. These members are in turn supported at their outer Aends respectively upon standards 22 and 23 by means of knife edge members 24 and 25 respectively upon said framing members 20 and 21, the same having bearing relation in the concave seats 26 and 27 respectively of standards 22 and 23. The inner ends of members 20 and 21 are arranged to overlie each other and are connected by link bar 28 in the manner shown, wherein the eye members of said bar engage with knife edge members 29 and 30 respectively upon framing members 20 'and 21. In thls manner of support, assuming that the framing members 21 are held under yielding support, the

ymaterial passing with the travel of draper member 9 will cause said draper member to be depressed, and similarly the framing members 20 and 21 in varying degrees in Conformity with weight ofmaterials.

With a view of counterbalancing weight for the belt member 9, I have provided the scale beam member 31 having the counterweight`32, said beam being supported in standards 33 through the knife engagement members 34 thereon engaging curved seats in the upper ends of said standardsv 33. This scale beam member in practice is designed to be connected to support a cross frame member 35 of thc main framing member 20, as best shown in Figs. 3 'and 8. In

order to compensate for and to facilitate the slight rocln'ng motion of beam 31 to the frame member supported by it, I have provided the lugs 36 and 37 respectively upon the beam member and the transverse frame member and the interposed block member 38. This manner of support serves, under proper counterbalancing, to cause any depression of the draper member below the normal to be imparted to beam 3l.'

To the end of recording variations in weight of materials passing over the belt or draper member, I have in mind, as in the earlier application referred to, the idea of utilizing relatively movable disk members as means to the end of registering such -variations yin Weight, but have developed improvements on this feature of my invention which will be hereinafter more particularly pointed out.

Referring, then, to the means and associated mechanism serviceable for the purposes of imparting movement and registering variations in weight of materials passing over the draper member, 39 is a shaft supported at one sidein box 40 on framing member comprising uprights 41 and cross frame member 42. This shaft is supported at the opposite side of frame 2 in box member 43 on standard 44. Shaft 39 is connected tobe driven from shaft 8 through sprocket Wheel 45 on shaft 8 and sprocket Wheel 46 on shaft 39, and sprocket chain 47 connecting.

to the position of shaftor pin 52, and is supported in` bearings in members 55, which said members are supported from or form a Y part of framing arm 56 which. said framing member is in turn connected and supported with framing member 57, said framing member 57 being bolted to the upper ends of standards 41 as shown in Figs'. 1 and 4. 58

is a cross framing member connected with or forming apart of frame 57 and is con' nected with or forms a part of standard 44 and is provided as an additional support for said frame 57 to that of its connection with uprights 41. Y By means of the suppdrt of shaft 52 in bracket 53 and the support of said bracket from shaft 54 journaled in members 55, disk 50 is permitted to be turned at an angle with relation to pivoting `disk member 48 on'arcs conformatory with those of said disk. Disk 50 normally is designed in practice to be driven from contact springv member 59 is provided, the same be ing carried upon shaft or pin member 52, and interposed between fork members 51 and the inner end 0f bracket 53.

I have provided means for changing the position of disk member 50 with relation to concave disk 48 with the depression of l draper member 9 and resultant movement of' beam 31. The particular means employed for thispurpose comprises a shaft member 60 having trunnion extensions 61, which said shaft is j ournaled at one end in the bearings comprising rollers 62 and at the other end in boxing member 63 which is secured at the inner end of framing member 64, the latter being fixed to the frame 57. To the shaft is secured a weight member 65 by means of reach 66, said reach being connected respectively with shaft 60v and .weight 65. This Weight serves to maintain the shaft in normal position. To shaft 60 is attached in a rigid manner the arm 67, and to said arm is connected in a pivotal manner link member 68, the lower end thereof being provided with the yoke 69 whichsupports ring members 70, said ring members serving asa support`or connection with beam 31 through the knife edge members 71 projecting from either side of said beam. This connection of shaft 60 with beam 31 serves to convey the movement of said beam to the sleeve, serving to rock the latter upon its support 61. To the innerend of shaft 60 there is fixed the arm 72 provided at its outer end .with the open slotted Way 73 best shown in Fig. 6. To one of the fork members 51 is fixed the reach 75 extending parallel with disk 50 to the outer edge thereof, and then inturned, and then extended for the purpose of alining the outer portion of said reach with the edge of said disk. The outer end of reach 75 extends within the slotted way in arm 72. Disk 50 is normally placed slightly off center of disk 48, that is, the bearing of disk 50 is a little to one side of the center of the axis of support for said disk 48, this for a purwith traveling disk member 48 and to the -end that such contact shall be constant,

pose. to be explained. Arm 72 is positioned to hold disk 50 in its normal position slightlyv off center with relation to disk 48 and as beam 31 is moved downwardly, disk 50 will y disk 48 and similarly, when beam 31 rises, disk 50 will be turned to travel toward the center of disk 48. In this manner of connection between` arm 72 and the fork members 51 which support disk 50, there is no bodily movement of disk 50 upon the surface of disk 48, asin my former patent herein referred to, and hence the friction clutch is dispensed with, said disk traveling and moving forwardly in such change of position relative to disk 48.l The movement or change of position of disk 50 with relation to the surface of disk 48 the circumference of changes both the distances between arm 72 and said disk 50 and .also the angular disposition of reach 75 with relation to slotted way 73 in said arm, which said ydiffering in relative positioning is -readily taken care of by the said slotted way. The action of these parts is best seen in Fig. 6.

The speed of movement of disk 50 is adapted to be registered or measured, and'to this end a proper meter or register 76-is "provided which may be of any suitable cons struction, to serve the purpose. is supported upon plate member 77 and is adapted to bedriven by connection with an axial spindle 74 of said disk 50 through coil sprlng Amember or flexible shaft 79.. Disk member 50l is normally placed slightly removed from the. axial center of disk 48 as actual centering o'f these members would f render them inoperative, since the movement of disk is dependent for travel on contact and angular positionin with reference to disk 48. Therefore dis 50 must be oil" center with relation to disk 48 to receive any impetus from the latter. As a consequence of the relative placement of disk 50 olf center from disk 48, disk 50 would run at all times regardless of whether materials were passing upon the draper belt. Hence it is necessary to compensate for such-movement, and to this end I have provided a planetary gear mechanism 80 (not illusv trated or described in detail as it is a gear of well known type and forms nopart of my present invention). I .also provide a connection for driving this gear comprising sprocket wheel 81` on Shaft 39, gear wheel 82 on shaft- 83, the latter supported o'n bracket members 84, sprocket wheel 85also on shaft Y83, lsprocket lwheel 86 connected with slfeeve member87 of the planetary gear organization, and Xsuitable sprocket chain driving connectionsj between the sprocket wheels mentioned. The effect `,of the interposition of the planetary gear and driving connection therefor is to exactly counterbalance the .driving speed resulting in a normal placement of disk 50 when the machine is run- .ning but the traveling draper carrying no materials. However, as disk wheel 50 moves fromits normal position toward the circumferencepf disk 48, movement will be im- Register 7 6 combination,

parted to the registering mechanism to proprlyl; measure the distance traveled by said In operation, the parts of the device having been disposed in the related positions shown and power having been applied to operate the traveling members, including the draper belt kand disk member 48, grain or other materials passing to the draper belt will be passed over the' depressible members of the frame, causing the latter to be depressed and` therewith the scale member, which depression of the' scale member, through its connection with disk 50, will cause the latter to be turned more orless, as the weight is greater or less. With the turning of the disk 50, thetravel of disk 48 will cause said disk 50 to be moved toward the circumference of disky48, thus increasing the speed of the former in proportion as the dlstance increases from the axial center of l disk 48. The diminishing weight 'will be marked by inclining the disk toward thel l axial center,resulting in its traveling in that direction. A sudden discontinuance of weight upon the traveling member and the depressible members will be automatically taken care of through and by a positioning weight 65 on sleeve 60. The travel of disk 50 will be transferred through its connection lwith the registering mechanism as hereinbeing member, a second disk member adapted to be actuated by the rst named disk member, means for shifting the second named disk to different" angular positions with relation to the first named disk operable through the movement of the scale beam.
