Fig. 6 is a detail sec 20, fastened to the lower extremity of the ac- Ico tuator-shaft 14, and said actuator-shaft is thus geared directly to the seed-dropping shaft to be rotated positively thereby.

The registering-wheels are housed or contained within a easing 21, which is cast in disk form with a raised dange 21. The casing is provided with a slot 22 and with apertures 23 24, and it is also provided with a central bearing or boss 25.

From the polygonal seat 7 protrudes a eircular boss 26, which is coincident with the correspondingly-formed boss 25 of the casing, and these bosses are adapted to aline with each other and to abut together, so as to form a journal on which the units-dial 27 is mounted for free rotation. This units-dial is of a diameter proper to fit within the annular casing 21 of the register, and it has a central opening or orifice of such diameter as to en.- able it to fit snugly on the registering-bosses 25 26 of the casing and the frame 1 of said register. This units-dial is provided on one face thereof with a series of teeth 28, which' are spaced at regular intervals and are substantially V-shaped in form,as shown by Figs. 4 and 5. These V-shaped teeth 28 of the unitsdial lie in the path of the longitudinal rib or fin 15 of the register-actuating shaft 14, and said teeth are spaced apart at the proper intervals to provide su flicient clearance between the fin of the register-actuating shaft when the latter is rotated, whereby said shaft 14 is prevented from moving the units-dial beyond the proper predetermined distance. This units-dial is held under tension to prevent it from moving idly or under any conditions except by the positive impingement of the iin of the register-actuating shaft thereon, and the tension device for such dial is arranged in compact relation to the supporting-frame and the dial against which it presses. This tension device consists of a spiral or coil spring 29, which is seated in the annular socket 6, provided for its reception between the rib or iange 4c and the conical boss 5 of the su pporting-frame, and said spring is held securely in place by said rib and the boss, while at the same time it is free to expand and contract in the direction of its length in order to have the necessary frictional contact with one face of the units-dial. To prevent the spring from rotating with the units-dial and from retarding the proper rotation thereof by reason of the frictional contact between the spring,the supporting-frame,and the dial, I interpose a metallic washer 30 between one end of the spring and a face of the units-dial, and said washer is prevented from turning with the dial by providing a polygonal opening 31 in the washer and iitting the washer to the polygonal seat 7 at the outer extremity of the conical boss 5, forming a part of the supporting frame l.

snugly to the polygonal seat 7, to be held thereby against axial rotation while having theproper frictional contact with one face of the units-dial, and said washer is substan- This Washer 30 ts* tially flush with the face of said polygonal seat, so that the boss 26 only is exposed for the units-dial to ride thereon.

The units-dial is provided on its front face with a number of iigures--say from O to 15, inclusive-which figures are so positioned on the dial as to be exposed through the slot 22 in the casing 2l. The tens-wheel 32 is journaled on a pin or arbor 32'LL in position for its numerals to be exposed through the opening 23, while the hundreds-wheel 33 is likewise journaled on a pin or arbor33 to have its figures exposed through the other opening 24k in said casing. Each wheel 32 33 is held from undue rotation by the binding action of an elastic disk or washer 32h, and said disk or wash er is applied or fitted against the rear side of its proper disk, which is fastened to the arbor or pin in a suitable wayas, for instance, by heading or swaging the inner end of said arbor against the disk, substantially as shown in Fig. G--ewhereby the tension-disk is caused to bind or impinge against the registering-wheel to hold the lat-v ter in place by -frictional contact and yet permit the registering-wheel to move a limited distance when positively actuated by the working elements of the machine.

The units-dial 27 is provided with a stud 25a, arranged to engage with any one of a series of tangential teeth 36, formed on the peripheral edge of the tens wheel or dial 32, and one of the teeth 36n of said units dial or disk 32 is longer than the other teeth 36 thereof, so that said long tooth 36n is adapted to engage with any one of the series of tangential teeth 37, formed on the peripheral edge of the hundreds wheel or dial 33.

rhe bolt 10 passes through the conical boss, the polygonal stud, and the cylindrical boss 26 of the supporting-frame l, and it also passes through the central opening in the unitsdial and the boss 25 of the casing 21. The head 11 of said bolt lO is housed and held from rotation in the channel 9 of the supporting frame, and the protruding threaded end of this bolt receives a thumb or winged nut 12,'

which binds against the exposed front side of the casing 21, whereby a single bolt only is necessary to hold the operative parts of the register in proper relation to each other.

The worm-gear 1S is provided with an anguiar or polygonal opening or hub 13a to adapt it to t on the seed-dropping shaft 19 of the drill or planter in a manner to rotate with said shaft, and, if desired, the hub of said worm-gear may be provided with notches to receive a fastening pin or key for the purpose of holding the worm-gear against sidewise displacement on said shaft 19. It is not strietlynecessary to employ a means for holding this worm-gear against sidewise displace* ment, because the forked arm 17 of the supporting-frame 1 loosely embraces this wormgear and serves to hold the same in proper position with relation to the beveled gear 2O on the register-actuating shaft.

My improved register is readily applied to any ordinary grain-drill. It is only necessary to fit the worm-gear 18 on the shaft 19 of said drill and to fasten the supporting-frame 1 to the seed hopper or box, such attachment of the supporting-frame being readily effected by means of screws or their equivalents, which may be passed through openings inthe base 2. The worm-gear 18 is positioned on the shaft to engage with the beveled gear 20, and the worm-gear itself is engaged by the forked arm 17 to be free to rotate therein.

When the machine is in motion, the wormgear 1S is rotated to drive the shaft 14. At each revolution of this shaft 14 its iin 15 strikes one of the teeth 2S on the units-dial to feed the latter with a step-by-step mot-ion, and when the units-dial makes one complet-e revolution its stud 35 strikes one of the teeth 36 on the tens-dial 32. The latter dial at every complete revolution rotates the hundreds-dial through the medium of its long tooth 36 striking one of the teeth 37 on said hundreds-dial, and thus all the dials of the register are actuated successively and progressively to indicate the total acreage planted by the machine.

Myimproved register is adapted for use in connection with grain drills of different classes by providing interchangeable unitsdials having teeth which vary in number. In Fig. 4 I have illustrated a units-dial with a large number of teeth adjacent to its edge or periphery; but in Fig. 5 the units-dial has a smaller number of teeth arranged in annular series quite close to the central opening, by which the dial is supported on the alined bosses 25 26 of the register. The casing 21 of the register is readily removed by simply detaching the thumb-nut and withdrawing the casing from the bolt, after which one dial can be easily slipped off the bolt, another dial placed in position, and the casing and thumbnut replaced to connect and hold the parts in their proper positions for operation.

I am aware that changes in the form and proportion of parts and in the details of construction may be made by a skilled mechanic without departing from the spirit or sacrificing the advantages of the invention, and I therefore desire to reserve the right to make such modifications and alterations as fairly fall within the scope of the invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is
