' Beifi' 'known that I, PAUL A. WEYAND, a citizen of the United States, residing in the village of Maywood, county of Cook, and

which the cover is attaiihed ftdthe ba*i iY"'-- the regulator.

In the drawings, A represents the controlliar-casing in use on trolley-cars; On this ]State of Illinois, have inventeda new and useful Improvement in Electric-Motor-Controller Regulators, of which the following is a s ecification. I

y invention relates to that class of devices designed to automatically regulate the moveicasing the base B of the regulator'is secured 69 by screws or by other suitable means. On

The'object of my invention is to provide anautomatic regulator of cheap and simple construction that .by' direct and positive 15 action retards the movement of the controller while the current is being turned on, that 'can be easily attached to the controller in m'urannerin which-Iaccomplish my ob jects is described in the following specific-a and lllustrated in the accompanying tion, drawings, in which Figure l is a side elevation showing the regulator in position on the controller-casing.

are two series of ratchet teeth forming stops B and B the number and relative position of these teeth corresponding with the number and position of points in the controller.

In the center of the base is a cylindrical aper- 7 ture B, it's wall B extending the same height as the part B Midway between the series of the ratchet-teeth and wall B are two series of tetragonal cam-studsO and C These studs correspond in number and relative posi tion with the ratchet-teeth and forr an inte- Over the cylindrical part B and the interior of the base a cover D is fitted, the outside vertical part covering the channel B in the cylindrical part B This cover is secured on thebase by two clips D, which are secured in the recesses D in the cover D: The lip or lug D of each of these clips fits into the channel B is free to be revolved on the base. In the centerof the cover is a cylindrical aperture E. The wall E of this aperture extends. into the aperture B in the base. On the top of the cover and forming part thereof is a 0 radial jaw F, adapted to receive the shank of the controller-handle G, which is thereby connected withthe cover and by said connection the cover is revolved. Through the aperture E the controller-rod G extends. 5''

On this rod the handle G is placed.

Afiixed the boss H, forming part of the cover, is a pivot-stud I, which'projects on the inside of the cover into the interior of the base B. I andcenter hole I The vertical center of this recess corresponds with the line of an imaginary circle having its center in the center o the cover and passing through the studs C and C. On this pivot is a pawl J. The 10 s pivot-hole J of the pawl is slightly oblong, its greatest diameter being in the direction ngth of the pawl. From this pivot- Thus attached thecover I In this studis a countersunk recess. 10o

- her the pawl. In thi hole-a' a andS. On the underside near the free end ofthe pa'wl is an'oval post J, as shown in Figs. 4, d-and 7. On the top of the awl is an arm "K, which extends through. a s ot K, in the cover, inwhich it is free to move. To the upper part of .this arm two cupsK and K are attached, the cup K being perforated,- as shown at K, Fig. 5. 'These cups and armare covered by a box K, which is aflixed on the cover D. This box is provided with a lid K and an air-valveK, as shown in detailinFig. 11. I

When the regulator is constructed as described and illustrated in the drawings and attached to the controller, its operationand the movement of its several parts are as follows: The handle Gv is" placed on the controller-rod G, which projects through the aperture E in the cover D, the shank of the I handle resting in the jaw F, as shown in Figs. 1 and 2 and in position ready to be moved to turn on the electric current. In this position the pawl is free from contact with the ratchet-teeth and studs in the base and is held at rest in the normal position J -(see Figs. 4 and 6). The movement of the handle in the on direction, that is, to turn on the current, revolves the cover and pawl in the direction of the arrow M (see Figs. 2

and 4), and as this movement continues the,

post J on the pawl strikes the end of the first stud in the series C and slides along its outer face. This contact of the post and stud forces the free end of the pawl outward from its normal position J to the position J 6 and into engagement with the first of the ratchet-teeth in the series B and stops the movement'of the controller at the first oint,

The force of the contact of-thepaw and tooth is transferred 'throu h the pivot end 11;. v..'I.he}oblon-g of the pawl to the stop-bloc pivot hole in the pawl prevents this force actingnon the. ivotstud and allows it to force the pin J ack on the spring J which the ratchct-toothi is thereby compressed. Before the controller can be movedto theznext' point the, handleunust-beslightly reversedso as to release the nose of awl from contact'with I I .hen this -is done, the 'pressureof the sprihglf, forces'the pin J into the center of -the recess 11 in} the pivot I.

This force moves thepawl back/to the nor" mal'lposition'Jgand places the post J bethe second stud, the pawl bei tween the ends of the first-and second studs inseries Thecontroller can then .-be

moved forward again, the post J striking the end and sliding along the outer face of' thereby forced outward into the'position "and into contact with the second ratchet-tooth in the series B, the controller being thereby stopped at the second point. The handle is again slightly reversed, the pawl resumes its .normal position again, and thecontroller can be then moved to the third oint. These movements can be repeated till each of the ratchet-teeth vin both series have been engaged by the pawl and all the points have been made by the controller and the full current thereby turned on. The reverse movement of the controller in the direction to the arrow N, whereby the current is cut off, can

:be made at any point in the revolution of the handle,rod and regulatorcover.- When the reverse movement begins, after the pawlpost J 8 has passed one or more of the studs in the series C or C,the post stazikes the reverse end of the nearest stud andslides along the inside face of the stud, thereby forcing the pawl to the inside uposition J, as

shown in Fig. 4, and out of a 'possiblecontact with the ratchet-teeth or other part of the interior of thebase. It will be seen that during the movement of .the controller handle in the on direction the 'part of'the pawl which is. engaged by thecams'or studs '0 andC, that is, the pawl-post J travels in a path or way outside of the said studs, be-

tween the studs and the ratchet-teeth, while during the reverse movement of the handle the said part travels in a that is, at the o posite side of the studs, the latter then hol ing the pawl'out of contact with the ratchet-teeth or stops. If it is desirable to retard the movement of the pawl from the outer osition J 6 back to the normal position J and thereby time the movement of the controller from point. to point, it can be accomplished by roviding the. awl with the arm K, cups 1% and K slot in the cover, and a box K With the regulator so constructed each forward movement of the controller-rod, handle, cover and pawl compresses the cup K and expels the air from within the cup through the air-valves tends to 'create'a vacuum in the on and retards the movement of the pawl til that vacuum is destroyed by the flow of air through the air-valve.- This flow of air can be regulated by the adjustment of the air-valve. The cup K when compressed by the reverse movement simply assists the action of the s ring J 3 and in J in forcing the pawl from t ienposition back'to' the position J e interior of the base may be filled with V a suitable lubricant to reduce the frictionof the moving parts, the cylindrical part B and 'wall 13 of the base and the cover D and the path or way inside,-
