lMPROVEM'E-NT l-N TONGUELESS PLOWS.

Specification forming part of Letters Patent No. 187,983, dated March 6, 1877; application filed October 10. 1876.

To allwhom it may concern:

Be it known that we, WILLIAM F. REEVES, @AL'FRED B.:REEvEs,and MARSHAL T.REEvEs, i of Columbus, county of Bartholomew,-State of Indiana, have invented certain new and usei'ful I Improvements in Tongueless sPlows, of which. the following is adescription, referzence being had to the accompanying drawungs.

, .Uur invention consists in the construction, arrangement, and combination of parts, as will be hereafter fully'described, and set forth in the annexed claims. Figure 1 represents a side elevation of our xiimproved-tongueless plow. Fig. 2 is a plan view of one-half of the same. Fig, 3 is a sec tiona1 view ofithe wheel, axle, and its connectionswith the arched axle. "Fignd is a sectional view of the axle spindle and caps. 'FigriiiS a sectional view of the boxes that :supportthe arch.

A represents the wheel of the plow, which i has its hub'j bored out and turned upon the outside at each. end. The spindle t, Figs. 3 andd, is formed with a cap, m, at one end, which may be provided with a lug, r, as shown, to operate in a slot, E, formed in the down ward-projecting arm D of the arm B, which --will be hereafterdescri-bed. Said arm, however,-may be solid or slotted. The cap in in: $03,888 one end of the hub j in the annular re .cesses s s, and the lower part may be cut away to allow anydirt that may accumulate "-1.0. drop out, as shownin the drawings. The main partof the spindle t is turned to fit in "the hole formed 'in the hub j, and is formed hollow to receive the bolt n. The outer end of the spindle it may be provided with a projecting lug, g, which extends 1 beyond the hub j, and enters a recess formed ;in the cap it, as shown; or there may be other modes-of securing the cap 70 to the spindle t, -soas to prevent it from turning, without departing from the spirit of our invention, thus preventing the cap it from turning as the wheel Airevolves. The cap it also has an annular 'i recess that incases the end of the hub j, and p-it may be cut away on its lower side, to allow .w-dirt towpass out; and when secured on the hub j with the spindle t, by meansof the bolt 71., the wheel A is free to revolve, and the open sides of the caps remain down.

The spindle t is secured to the projecting arm D of the hooked arm B O by the bolt 7, as shown in Fig. 3.

The lug r on the cap m of the spindle t is designed to operate in the slot E or hole drilled in the arm D, and prevent the spindle from turning around. The hooked arm B O is formed with two side-projecting wings or jaws,p p, in the ordinary manner; .but the downward-projecting arm D is located at or near the inner end of the lower jaw 10, as shown in Fig. 3. The design of this position of the arm D is to allow plenty of room below for a long hub to the wheel A; also throw the draft on the hook-arm B U as close to the wheel as possible. The feature gives great advantage in draft and length of bearing of the hub of the wheel, and durability to the hooked arm B O, by having the weight and strain evenly proportioned over the joint, and also, for the same reason, gives more durability to the hub.

The old plan of attaching the spindle to an arm, D, projecting down from the outer end of the jaws 19, throws a great strain on the joint of the arch'bar, and also on the spindle, causing them to soon give out; also, by the old position of attaching the arm D to the hooked arm B G, if the wheel meets with obstruction it is much more liable to deviate from a straightforward line than by our ,arrangement thereof.

Thejaws p p are pivoted to the arch-bar G in such a manner that any lateral movement of the hook-arm B U will carry with it the wheel A, as indicated by the dotted lines at B A B A The jaws pp extend far enough beyond the bolt G to receive a pin or catch, B, which passes through the arch-bar G as shown in Figs. 2 and 3. By this arrangement,

the hook-arm B C and wheel A are securely held at right angles to the arch-bar G and if removed will allow an angular position to be given to the wheel A and hooked arm B G, as before described, thus forming a rigid axle or an adjustable axle, as may be required. The precise form shown for securing the jaws p p to the arch-bar G in a rigid manner may be varied, so that the desired effect is produced without departing from our invention.

The boxes H J are designated as supporting-boxes to the arch-bar G to hold it in its position, and at the same to form an adjustable or pivoted connection with the plowbeams M.

The upper and lower halves of the box H and J are formed to encircle the sleeve G and work thereon, said sleeves having lugs g 9 above and below, which operate in elongated slots u u formed in the half-boxes J H, as shown in Fig. 5. The sleeve G is designed to fit onto the arch-bar G, as shown, and by being provided with the lugs g g, which operate in slots u u, the forward and backward oscillation of the arch-bar G is regulated. The box H is provided with a nutlock, 1, so arranged and pivoted to the top of the box H as to engage with the nut or bolt K, and prevent it from working off. The two half-boxes J H are united to the plowbeams by the pivot-plate L and bolt K, which also secures the two halves J H together, and forms a pivoted bearin g for the plow-beams M. The front edges of the half-boxes J H have lugs z z united by means of the screw-bolt h. The inner front edges of these lugszz are beveled off, as shown at w in Fig. 5, the design of which is to prevent the lugs z from being broken off in case the rear oolt K should be detached, for if the rear bolt K should become lost then a forward motion of the wheels A, and resistance of the plows, would cause the two halves of the boxes J H to spread open, which would (if the front lugs 2 were square at their union) cause them to break ofl, while by giving them the bevel shown in Fig. 5 they will allow the bolt h to bend or break, but will not break themselves, the advantage of which can be readily seen.

The plow-beam M M M is formed of flat bar-iron in the shape shown in Fig. 2. To the front end the pivot-plate L is securely fastened by bolts or rivets, as shown. The handle N is secured in the usual manner, and braced by the bar 0. The shovel-arms P P are pivoted to the frame M M by the screws or bolts '17. On the side of the shovel-arm are slide-loops S, in which operates the break lock-strap 1%, one end of which is pivoted to the frame M, and the other end slides in the loop S. This end has a slot or series of holes, in which is inserted the wooden pin S to be operated in the usual manner.

The lower end of the shovel-arms P P may be made straight, as shown at T, with the proper angle given to allow the shovel V, when attached, the proper pitch; but we find that the curved shank T, as shown on shovelarm P, is far superior, as by it we can obtain any required pitch to the shovel V, as shown in Fig. 1, which is of great value to a shovelplow.

The slide W of itself is old, and to this we make no broad claim; but only to the addition of the spring-board X, which is secured, as shown, to the slide W, and made to hook over the top of the shovel V by hook Y, thus holding the shovel with its point fin a hole formed in the slide perfectly firm, not allowing the shovel to jump 0E the slide, as heretofore.

Our improvements, as hereinbefore set forth, are of great value to the machine to which they are adapted.

We do not broadly claim the hooked arm B 0, slide W, and pivotcoupling L K, as they are old.

What we claim as new, and wish to secure by Letters Patent, is-

1. The spindle t, formed with a cap, m, said cap having an annular recess, 8, between its front edge and spindle to receive the end of the hub j, and having a projecting lug, g, at the front, to enter a corresponding recess formed in the front cap it, all constructed and arranged as shown and described, for the purposes set forth.

2. The spindle t, formed with a cap, m, which is provided with a lug, r, at its rear, and an annular space, 8, to incase the end of the wheel-hub in front, and said spindle being further provided with a projecting lug, 31, at its front end, to engage with the front cap it, and adapted to be secured to the arm D of the hooked arm B O, in the manner and for the purposes set forth and described.

3. The combination of the pivot hook-arm B O, constructed as described, the arch-bar G pivot-bolt G, and stop F, in the manner and for the purpose set forth and described.

4. The slide W, provided with spring-board X and hook Y, all arranged and adapted to be operated in the manner shown, for the purposes specified.

5. The hooked arm B 0, having a downwardly-projecting arm, D, constructed as described, and placed at or near the inner end of the lower jaw p, in the manner set forth and described, for the purposes specified.

6. The two half-boxes J H, constructed to clasp the sleeve G and to come in contact wiih each other at their central joint, in combination with the sleeve Gr", said sleeve being provided with a hole having one or more flat faces that fit on corresponding shaped axle G, the sleeve G being provided with lug g or lugs g 9, arranged to operate in elongated notches u or u u of the boxes J H, in the manner and for the purposes set forth and described.

7. The lower end of the shovel-arm P, provided with the curved shank T, said curved part being bent or curved backward, (not forward,) and adapted to receive the shovel V, and to allow said shovel to be adjusted up or down for the purpose of regulating the pitch of the shovel, as set forth and described.

8. The hooked arm B 0, having a downwardly-projecting arm, D, located at or near the inner end 10, combined with the bar G and with a pin, F, adapted to openings in the arm and bar, as set forth.

9. The combination of the pivoted arm B'O, having a slotted arm, D, the hollow spindle t, having a lug, 'r, and the bolt n, adjustable with said spindle in the slot of the arm D, and confining the spindle to said arm, as set forth.

10. The two half -boxes J H, arranged to clamp the pivotplate L in a loose manner at the rear, and to extend over and clamp in a loose manner the sleeve G and to come together at their inner faces in front of the sleeve G at the lugsz 2, said lugs having their inner front edges beveled off to allow E.
