To LZZ whom t may concern,.-

Beit known thatl, EDWARD P. RoBBINs, a mechanical engineer, and a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Movable Vehicle-Steps and Connections; and I do declare the following, to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and gures of reference marked thereon, which form a part of this' specification.

My invention relates to a movable vehiclestep and connections, and is intended to be adapted to four Wheeled vehicles having bodies placed high above ground-as buggies and eXpress-wagons-and where the forward wheels turn in against the sides of the body or under it when turning short. A four- Wheeled box-body side-bar buggy will be taken as a type.

The object ot' my invention is to provide a movable vehicle-step which may be placed nearer the ground and farther out from the vehicle-body than has previously been practicable and near the rim of the fore wheel when the latter is in line with the hind wheel, so that when the fore wheel is turned away from the body the said movable step Will be in the most convenient position possible for stepping into or out of the vehicle.

As steps have been previously constructed for high buggies, they have been placed so high from the ground and so located With reference tothe movement of the fore Wheel that it has always been diiiicult and awkward for ladies and children and still more so for aged persons to get into or out of a buggy. The object oi this invention, then, is to overcome these ditliculties. A second and stationary step, which may be directly combined in construction with the supports of the said movable step, or which may be independently attached to the vehicle-body or the framing, and which may be the usual step or may occupy a position similar to that of the usual pendent step, may be used in connection with the said movable step. Vhen the said steps are ready for use, the stationary step will be aXis of rotation could be inclined somewhat from a vert-ical position outward from the vehicle-body, if desirable. The said step may also be arranged to move up and down along the said axis of rotation. The said axis of rotation may be so located with ref erence to the vehicle-body and the adjacent fore wheel and with reference to the inward movement of the latter when turning that if the movable step should be unintentionally left in its lowest and outermost position, or should in an accident drop to the latter position, then the said fore Wheel in turning in against or under the body will automatically push the movable step inward out of its way, so that the step cannot catch in the Wheel. This provision for the automatic movement of the step by the fore Wheel is one of the essential features of this invention, for Without it no movable step could be placed in certain positions intended, asa slight turn of the fore Wheel would cause the step to catch between the spokes. It would not be practicable to have a step fixed at as lowa position as that of the movable step when in use, as the xed step would catch or strike obstructions, especially in the country and in ields, Where stumps, rocks, brush, and undergrowth must be driven over, while such fixed steps would make the vehicle appear unsightly.

Various means may be employed for raising and lowering the movable step; but when the requirements thereof are considered with reference to the various styles of vehiclebodies it will be seen that the means herein illustrated and described are the only ones which will be Well adapted to the varying conditions consequent to the changes of styles made in the front part of buggy-bodies. All

such vehicle-bodies must have a front adapted to receive and support the feet, and While the style of the body may be continually changing this part must remain approximatelythe same. The means illustrated for raising and IOO lowering the movable step is well adapted to permit variations in buggy-bodies, and hence is preferred. Again, such means must be convenient of operation whether the operator is mounted. upon the seat or stands upon the ground, and none of the parts must be in the way nor liable to catch clothing, especially in jumping from the vehicle in case of accident, and such means must be so adapted to a given style of vehicle as not to mar its appearance whatever the style of the vehicle-body. Further, the means employed for operating the movable step must have a positive action in order that children or aged persons may be able to operate it with certainty, and there `must beno possible chance for an accident on account of the movable step being negligently left down or on account of its being vdropped by any accident in case of a runy It is believed that the invention herein set f forth will answer all of the above require- Vfore wheel; d, that of the rear wheel. ,line 7c c represents one-half of the front axle,

Figure 1 is a side view of a four-wheeled box-'body sidebar bu ggy havin g my improved step and connections, the sections being along the lines 20, and e* c of Fig. 4. Fig. 4 is a plan of one-half of the same, the section of the body being along the line w w of Fig. 1 and the bottom being partly broken away. In both Figs. 1 and 4 the parts of the step and step-connections are made on a slightly larger scale than the other parts of the buggy to insure perfect illustration. Fig. 5 is a plan ot' the movable step and its supporting-framing, the upright 1 being in section along the line y 'y of Fig. 1. Fig. 6 is an elevation of the same corresponding to the view in Fig. 1, the upright 1 being partly shown in dotted outline, and the shank 8 ot the movable step being shown removed exterior to its section along the line n n of Fig. 7.. The lines m m in Figs. 4, 5, and 6, indicate they relative positions of the parts. Fig. 7 shows the movable step 9, its shank 8, and boss 4 separate from other parts. Figs. 11, 12, and 13 show modifications in the construction of the details of the movable step and its supportingframing. Figs. 2, 3, 8, 9, and l0 show details of the movable step-connections.

The same letters or numbers indicate the same or corresponding parts, and the prime numbers the dotted positions which those parts may occupy when moved from the positions shown, dotted lines also indicating the movement of those parts.

In Figs. 1 and 4, 50 and 52 are the body ends, 51 the sides, and 55 the bottom. 53 is `the side or bottom frame-piece, and 54 is the front-end cross trame-piece. 56 is the usual bottom middle stay and support, and 57 is the dash. lc is the king-bolt; c, the center of the The the line b d one-half of the rear axle, and t represents the tires. 30 is a side bar.

The invention is illustrated as applied to a side-bar buggy, because that kind of a buggy is adapted for the use of various improved springs, some of which are placed crosswise and others lengthwise of the body, and it is intended to show that it is practicable to use my movable step and its connections in building side-bar buggies with almost any kind and arrangement of springs, as well as when building buggies having a plain body supported upon the ordinary elliptic springs.

In Figs. l and 4 a step-supporting frame 1 11 12 is shown,which is intended to be forged, and which consists of an upright 1, having a circular cross-section and attached at its upper end indirectly to the vehicle-body, a brace 12 running at an angle from the lower end of the upright 1 forward to the side of the bottom, where itis attached, and a second brace 11 running at an angle backward and upward from the lower end of the upright 1 to a suitable point under the vehicle-body, where it is attached. These three

parts

1, 11,and 12 when attached together at their lower ends and attachedattheirupperendstothevehicle-body form with the latter a pyramidal frame having great strength forasmall amount of metal used and capable of standing considerable inward pressure at the apex or place where the three parts unite. This triangular frame is an important part of the preferable mode of supporting yand guiding the movable step. This frame may be constructed as shown in Figs. 1, 5, and 6, where the upright 1 may be an ordinary bolt having a body l, head 22, and nut 23, where the

braces

11 and 12 unite and a boss 2 is formed with a central hole h, through which the lower end of the bolt 1 passes and in which it is secured, where the brace 12 has a boss 13 and hole for attaching it by means of a small bolt to the body side piece 53, and where the brace 11 has a boss 14 and hole for similarly attaching it to the body-bottom 55. By incasing the body 1 of the bolt within a thin metal tube extending from the body side piece 53 to the boss 2 this tube may be compressed between the said parts when the nut 23 is tightened, and thus the

triangular frame

1, 11, and 12 be made rigid and the parts be prevented from becoming loose and rattling. Fig. 3 shows a cross- Section of the bolt-body 1 and the said eXterior tube 58. Thelatter has an important additional function to perform, which will be considered later.

The movable step 9 (shown in Figs. 1, 4, 5, 6, and 7) has a shank 3, extending from a boss 4, which has a central hole h, through which the upright 1 is passed before the parts of the said triangular frame are secured in place. The perforated boss 4 is adapted to rotate about the upright 1. Itis also adapted to be moved up and down upon the latter. Again, it may be rotated about the upright 1 while being raised or lowered. When the boss 4 is in its lowest position, the step 9 should be in position for use, as shown in Figs. 1 and 4. When the boss 4 is in its elevated position, it

swinging loose or rattling.

should be turned away from the adjacent fore wheel and under the vehicle-body, and it is Apreferable to provide means forpreventin g the step when in the elevated position from Again, when the movable step 9 is in position for use, it must by some means be prevented from displacement. Otherwise a person would be liable to slip or fall.

In Figs. 1, 4, 5, 6, and 7 a simple and efficient means is shown forholding the movable step stationary while being used. The said means is at the same time adapted and has been adopted to guide the movable step in its rotation about the upright 1 from its inner to its outer position. The supportingboss 2 is forged integral with the frame-supporting

parts

11 and 12, has an inclined guiding and supporting surface 3, a plane surface 7 at right angles to the upright 1, and a plane surface 5 parallel with the upright 1. The lower part of the step-boss 4 has a construction to correspond-that is, an inclined guiding-surface 3, a plane surface 7 and a plane surface 5a-so that when the boss 4 is in its lowest position the said surfaces on its lower end come into contact with the said corresponding surfaces on the upper end of the supporting-boss 2.

lf the movable step is first supported in its elevated position and turned in under the buggy-body and then dropped or permitted to lower from that position, the inclined surface 3L near to 5a will come into cont-act with the corresponding inclined surface 3 of the supporting-boss 2, but near the plane surface 7, and if the said surfaces 3 and 3PL are sufficiently inclined then the boss 4 will continue to descend and the surface 3 will slide upon and be guided bythe corresponding surface 3 until the plane surface 5 comes into contact with the corresponding surface 5, or the plane surface 7 a comes into contact with the corresponding surface 7, during which sliding action the movable step 9 will be rotated about the upright 1 from its innermost toits outermost position. It is easy to imagine that abuggy may sometimes be standing upon an uneven or an inclined surface, such as would so incline the said parts of the movable step and its supports that were the movable step to be dropped from its elevated and innermost position it might in falling be rotated by gravity about the upright 1, more or less, through the angle required to bring it to its lowest position, as shown in Figs. 1 and 4. Cases might happen where it would be rotated through even a greater angle before the lowest point on the boss 4 would touch the boss 2, in which cases the lower end of the inclined surface 3a would first come into contact with the boss 2 at some point farther around than the plane surface 5, and were the construction as so far eX- plained then the boss 4 would not seat itself properly upon the boss 2. ln order to provide for such contingency, an inclined surface 6 may be formed on the boss 2 between the plane surfaces 5 and 7 and a corresponding inclined surface 6 be formed on the boss 4 between the corresponding plane surfaces 5 and 7 a, as shown clearly in Figs. and 7, the surfaces 6 and 6a being inclined downward from in front around in an opposite direction to the downward incline of the surfaces 3 and 3a. With this additional formation, were the lowest point on the boss 4 to touch beyond the plane surface 5, the movable step would be arrested in its outward rotation and be guided by 'the inclined surface 6 backward until it could drop to position. In fact, the said inclined surfaces 6 and 6L could replace the plane surfaces 5 and 5a and 7 and 7 L, respectively, whereby an angular upward projection would be formed on the inner side of the upper end of the boss 2 and an angular depression would be formed on'the outer side of that end. By these means provision rwill be had for guiding the boss 4 positively to its seat.

When the boss 4 is properly seated upon the boss 2, as shown in Fig. 1, the movable step 9 is in position for use, as seen in Figs. 1 and 4. The downward pressure of the foot upon the step 9 when in this position will tend to firmly seat the boss 4 in its bearings upon the boss 2. Any lateral pressure around forward will be opposed by the contact of the parallel surfaces 5 and 5, The horizontal component of a downward pressure acting to force the step inward will be opposed by the inclined surface 3 of the boss 2. Consequently when the foot presses 'upon the movable step 9 the latter will be maintained stationary, and there can be no danger of its becoming displaced and causing a person to fall; but when there is no downward pressure upon the step 9 a slight lateral pressure exerted against the front edge of the step will cause it to rotate inward and the surface 3 of the boss 4 to slide upon the corresponding incline 3 of the supporting o1' stationary boss 2. Consequently when the adjacent fore wheel is turned inward toward the buggy-body, if the step-boss 4 is seated upon the stationary boss 2, the tire t will strike against the step 9 and force it around under the buggy-body.

The step-shank 8, together with the length of the step 9, can be so proportioned and the upright 1 so located with reference to the vehicle-body and the adjacent fore wheel as to be applicable to any given style of vehicle upon which it is proposed to use the said movable step, and the said proportions may be such that the tiret will remain in contact with the step when the fore wheel is turned inward as far as the body and running-gear will permit; but in order that the step 9 shall not require to be made too long, and consequently out of proportion, the shank 8 is divided into two branches, which diverge and connect with the step 9 at its rear corners in such manner that the outer edge of one branch is made continuous with the corresponding outer edge of the step, as shown clearly in ICO IIO

Figs. 1, 4, and 5. The fore Wheel may then -rub against the continuous edge 15 of the step 9 and the shank branch.

In Figs. l and 4 geometrical projection is used in explaining the relative motions of the 4movable step 9 and the fore wheel c t.

Referring to both Figs. 1 and 2, when the fore wheel c t is turned inward, the front axle 7c c rotates horizontally about the kingbolt 7c, and the point t, Fig. 4, on the tire of the fore wheel is supposed to be on a level -with the lower edge of the side bar 30, as shown by the dotted projection-line connecting the point t in Fig. 4with tin Fig. l. Were this point rotated horizontally about 7a, as shown in Fig. 4, it would strike theside bar 30 at the point t', Figs. l and 4. The point o on the tire in Fig.4 is on a level with the step 9, as shown b'y the projection in Fig. l. Were this point to rotate horizontally about k along the arc 0 0', Fig. 4, it would strike the step 9 at o, and if the wheel ct were turned inward still farther it would push the step ahead of it, and the point of contacto would move in the arc o 0. When the fore wheel c t is turned inward as far as the side bar 30 will permit without tilting the body, its tire will be in contact with the side bar 30 at t', Figs. l and 4, and the tire c t is then represented in plan in Fig. 4 by the dotted line c t', the axle being then in the position 7c c. When the point t reaches the position t', Figs. l and 4, the tirewill have pushed the contactlpoint 0 along the arc o 0 to the position o within the' circular arc v QJ o, having its center in the axis of the upright l. Now, if the wheel c t is pushed farther inward (by being forced under the side bar 30) the point of contact between the tire and the step 9 would move farther along the arc o 0 0 and could be moved as far as the position 0 before the tire could slip past the outer end of the step 9 and permit the latter to catch between the spokes of the wheel c t; but it would require a greater turn than would ever occur, except in some peculiar accident-as a runaway` to move the point of contact as far inward as the point 0.

Figs. l and 4 show the upright 1 vertical and its upper end secured in a projecting plate 21, which may be attached to the under `side of the side frame-piece 53 by means of small bolts passing through the holes 24. As seen, by the. use of the projecting plate 21 the upright 1 may be placed beyond the edge of the buggy-body. In a side-bar buggy, where the side bar is placed a little distance from the buggy-body, as shown in Fig. 4, this arcured directly to the side frame-piece 53 by being passed down throughv a hole in piece 53 just inside of the side wall 51. It is preferable, except with very narrow bodies, to secure the upright 1 thus with a plain body without side bars; but with a very narrow body it may be preferable to use a projecting fastening, as a plate 2l, for the upper end of the upright l, and with such an arrangement a stationary step could be attached to or made integral with the plate 2l.

It is evident that the upright l, which is adapted to permit the boss 4 to be rotated about it or to be slid up and down upon it, or to be both rotated about it and slid up and down upon it, is the essential element of the step supporting frame. Consequently the brace ll alone might have a boss 2 and be combined with the upright l, or the upright l and the brace 1l might be forged in common with a boss 2 at their juncture, or the brace 12 alone might have a boss 2 and be combined with the upright 1, or the upright l and the brace 12 might be forged integral with a boss 2 at their juncture. Again, were the upright 1 comparatively short and thick, it might have a boss 2 for a head and have the nut 23 placed at the upper end, as shown in Fig. 13.

For some vehicles it might be desirable to place the uprightl sufficiently near the front end of the body or to make the shank 8 so short that the circular arc t QJ i; would always be inside of and clear the fore wheel when turned in against the body, as shown by the dotted line c t', Fig. 4, in which case the movable step 9 could be moved up and down without reference to the fore wheel, or it could be turned 'in under the vehicle-body when not in use.

For some vehicles it might be desirable to place the upright l so that the movable step 9 would always clear the fore wheel when turned in or so that the movable step would be pushed inward by the fore wheel, as previously explained, and yet where it would not be desirable or necessary to raise and lower the movable step. In this case a short upright l could be used, having a length just sufficient to permit the boss 4 to be elevated by the inclined surface 3 ou the supportingboss 2.

With some vehicles the coupling-frame might be so located or made that the movable step would require to be raised vertically from the seating position to its highest position before being turned in under the body, while with other arrangements it might be necessary to turn the step around under the body and not raise it much. These features may be provided for by slightly changing the location of the first pulley 18 of the lifting or turning chain, or when no pulleys are used by the direct pull upon the lifting or turning chain by the hand.

IOO

IIO

In any of the arrangements shown or sugl gested the same means is adapted to rotate the movable step about the upright 1 and hold it in its elevated or innermost position.

In Figs. 1,4, 5, 6, and 7 a short arm 1L) may be east orforged integral with a boss 4 or be otherwise suitably secured to it, and a chain be attached thereto, by means of which the movable step may be elevated or lowered. The upper end of this chain maybe movably attached within or without the vehicle-body and in a manner such as to be easily reached by the hand by a person mounted upon the seat or standing upon the ground; but it is believed preferable, in order to easily adapt the step-connections to any style of body, to arrange them as shown in the figures.

In Figs. l and 4 a chain 16 is connected at one end to the movable step-arm 10 and passed over a small pulley 18, supported in a suitable frame, which may be attached beneath the buggy-bottom 55 and then directed forward to the middle of the bottom and near the front end 50, where there is a hole 20, through which the chain is passed. As shown, a pulley 19 may be placed in the hole 20 for the chain 16 to pass over, and may be supported in a suitable frame, which may be attached to the buggy-body. However arranged, the upper end of the lifting-chain should have some kind of a handle attached thereto, and the handle or the upper end of the chain should be arranged to be fastened to some stationary device in such manner as to hold the step up firmly in its elevated position and arranged to be held within reach, and so that the chain may be slack and the boss 4 properly seat itself upon the boss 2 when the step is in its lowest position.

The space in the front end of the buggybody adjacent the dash has been chosen as most suitable for locating the parts of the step-connections which are to be operated by the driver on account of being out of the way of the clothing, feet, and wraps of persons seated in the vehicle, and because the parts to be handled may be reached by the driver while remaining seated or when standing upon the ground. Further, with t-he connections shown in Figs. 1 and 4 provision is made for operating the parts by the foot when seated, as well as by the hand. A guide placed crosswise in the angle between the dash and the door 55 and suitably attached to the framing, bottom, or walls of the body, along which and to which the means for attaching the handle end of the chain may be moved and fastened, is believed to be essential, especially for fiat-bottomed vehicles. For simplicity and economy of material and space the said guide has been combined with a foot-rest, so as to make the same cross-piece answer for the ordinary foot-rest and also for a suitable means of guiding and attaching the said handle-fastening device.

It has been discovered that with most vehicles having room for two persons upon the same seat the width of the body is more than twice the distance through which the boss 4 is required to be moved in elevating or lowering the movable step, so that each step may have a handle device arranged to slide upon and be fastened to the half of the said crossguide nearest it. When the movable step is in the elevated position, it is preferable to have the said handle-fastening located in the corner of the body nearest the corresponding step and as near the front and side Walls as possible', so as to be out of the way of the feet and clothing. Since the movable step on one side of the buggy only is used at a given time, when the handle -fastening of one step is moved along the said cross-guide the handle- 'fastening for the other step remains at its corresponding end of the said cross-guide, and consequently they do not interfere in being operated.

Figs. 1 and 4 show a combined foot-rest and cross-guide 31 33, located in about the position usually occupied by the ordinary footrest, the part 31 extending across the body and having shanks 33 at its ends, which support the part 3l at the proper elevation and which are adapted to be bolted to the framepiece 53. The part 3l may also have a middle support 48, Figs. 2 and 4. The details of these parts of the step-connections can be best explained by referring to Figs. 8,9, and 10.

The cross-guide 31 may vary as to the shape of its cross-section, and the corresponding connected parts may be varied in construction to suit; but the construction shown is believed to be preferable. The middle p0rtion of the cross-guide 31 proper is flat or oblong in cross-section, in order to adapt it for a foot-rest, and each end has a rounded portion 32, which may be forged integral with part 31, the front edge of the rounded portion and that of the flat portion being continuous or coincident. The rounded part eX- tends beyond the end of the flat part 31 into the rounded part 36, and with the construction shown in Figs. 1 and 4 the part 36 is made continuous with the supporting-shank 33. The end. 43 of the fiat part 3l is rounded off, as shown in Fig. 9. A device 34, having a circular hole corresponding in size to the rounded part 36 and a slot 43, opening into this circular hole and having a size corresponding to the flat portion 31, is placed upon and tted to the

parts

36 and 31 before the shank 33 is bent out of line with the rounded part 32 36 and the boss 33L is formed at the end.

As so far described, it is seen that when the device 34 is in the position shown by solid lines in Figs. S and 9, it is adapted to be turned about the part 36, but is then prevented from sliding along the'part 31 on account of the solid part being locked behind the end 43 of the fiat portion 31, and that when turned to the dotted position 34', Fig. S, it may be slid along the part 31.

\A stem 37 projects from the locking and sliding device 34, and preferably has a knob IOO 35 at its outer extremity, which may be of metal or wood, or of metal covered with some heat-non-conducting material, as leather, for the said knob is intended to serve as a handle to begrasped when operating the said locking and sliding fastening device 34 for the lifting or turning chain 16. The said knob 35 is also intended to act as a counterpoise when the device 34 is in the position shown in Fig. 9, so that the latter may remain locked behind the end 43 of the flat portion 3l. The end of the chain 16 may be attached directly to the device 34. Fig. 9 shows a clasp 38 fastened around the stem 37 and having a hole 39 for fastening the chain.

When the device proper 34 is of sufficient width, it may be drawn along the bar 31 by a pull on the chain 16 without catching; but when narrow it may be desirable to have a projection 42, Figs. 4 and 9, formed on its side, so as to prevent tilting and catching.

' The primary operation of the essential parts of the movable step-connections shown may now be described. Suppose the movable step shown in Figs. 1 and 4 to be supported in the elevated position by the chain 16 and the device 34 to be in the locked position shown in Figs. 8 and 9. When the parts are so arranged, the locking device 34 will fasten the upper end .of the chain 16 to the cross-guide 31 36 33 and maintain the movable step elevated and in its innermost position. Then the locking device 34 is turned to the dotted position 34,Fig. 8, the weight of the movable step 4 8 9 will cause the step 9 to descend and the chain 16 to draw the device 34 along the cross-guide 31 to the position shown in Figs. 1 and 4, when the boss 4 will properly seat itself upon the boss 2 and the movable step 9 will be in position for use. After use, whether the driver is standing upon the ground or mounted upon the seat, he may grasp the knob 35 in the hand and draw it to the end of the cross-guide 3l and turn it forward to the position shown in Figs. 8 and 9, when it will lock behind the end 43 of the cross-guide 31, and the movable step will be raised and turned to its elevated position. As seen in Figs. 4, 5, and 6, the arm 10 and the pulley 18 are so located that as the step is drawn up by the chain 16 it will be pulled around the standard 1 to its innermost position. The pulley 18 may be so located that the end of the arm 10 maybe brought against it, and consequently the movable step 9 may be prevented from swinging about the standard 1 while the vehicle is moving, and, further, that when the step is allowed to descend from such position the lowest point on the boss 4 will strike one or the other of the inclined surfaces mentioned on the upper end of the boss 2 and thus be guided around the upright l to position for use. However, when the brace 11 or the pyramidal frame 1 11 12 is used, it is preferable to make the cross-section of the brace 11 angular, as show-n by the section S in Fig. 5, and the cross-section of the shank 8 angular, as shown by the section S, Fig. 5, and to place the pulley 18 in about the position shown in Figs. 1 and 4, so that when the shank 8 is pulled around far enough its back lower edge will come into contact with the outer and opposite edge of the brace 1l,and so that the chain 16 may pull the shank 8 snugly against the brace 11 and hold it rmly against the latter when the movable step is at the elevated position. Vhen the step is so held, any rattling or swinging thereof will be positively prevented. In addition to such means of preventing rattling, a spiral spring 17 may be introduced into the chain 16 in such place as not to interfere with the guiding-pulleys 18 and 19, so that when the device 34 is slid to the locking position the spring will be sufficiently extended to continually pull the shank S against the brace 11. By making the stroke along the cross-guide sufficiently great the chain maybe slack and the spring free'from tension and the boss 4 properly seat itself upon the boss 2 when the step 9 is in its lowest position. The shank 8 and the brace 11 are given the angular cross-sections S and S', respectively, so that their opposing edges only may come into contact, and consequently the paint may not be rubbed off of them to any extent that would mar the appearance of the said parts.

It may be mentioned here that it is not intended that the fore wheel adjacent the movable step shall under any ordinary circumstances rub against and thereby disiigure the edge of the step 9 or its shank 8, for the movable step is not to be lowered except when the adjacent fore wheel is turned out of line with the hind wheel and away from the vehiclebody. The provision set forth for the contact and automatic co-operation of the wheel and step is intended to prevent accidents where restless horses are used or in runaways and the like. In this connection, also, it may be stated that the additional function previously referred to of the tube 58 onY the IOO IOS

upright 1 is to furnish a surface to the latter which shall not be disfigured by the frequent sliding of the boss 4 upon it. By usinga tube of brass or other non-oxidizable alloy or metal the same may be kept polished and always have a presentable appearance.

The upright 1 might be covered with leather and the boss 4 hushed with some such material in order to attain the same end; but I prefer the use of a metal tube. Y

The upright 1 itself might be made of a material which would not corrode or become disiigured by rubbing.

Where the body is very narrow and all the space possible is required for the motion of the device 34 along the cross-guide 31 and a projection 42 or a friction-spring 41 is used on the guide 34, the middle support 48 may be made, as shown in Fig. 2--that is, it may be bent as shown, and fastened to the under side of the cross-guide 31 and have a boss 49,

by which and a small bolt it may be attached to the end frame-piece 54. Such construction also permits of a rounded part, as 32, Figs. 8 and 9, being continued the whole length of the guide 31, as is shown by the section in Fig. 2, when so desired. W'here the buggy-body is exceedingly narrow it would be preferable to omit the middle support 4S.

It may be desirable to so arrange the stepconnections that the weight of the movable step 4 8 9 would not of itself be sufficient to cause the step to suddenly drop to position if the device 34 should purposely or by accident be released, as any consequent noise might frighten a wild horse. This end may be attained by the means shown in Figs. 3 and 9,

where a spring 41 is attached by means of a screw 40 to the side projection 42 on the locking device 34 and may be arranged to press upon the rounded front edge of the crossguide, as shown. The arrangement shown permits of any required amount of friction between the spring 41 and t-he cross-guide 31, and consequently is adapted to hold the sliding device 34 at any required position on the cross-guide or to prevent the sudden descent of the movable step. Of course the spring 41 could be attached directly to the main part of the device 34 where no projection 42 was used; but when the parts 42 41 40 are placed as shown in Fig. 9, where the device 34 is in the locked position, they are liable to catch a ladys dress in jumping from the vehicle. It is therefore preferable to contin uethe rounded part 32 the whole length of the cross-guide and place the parts 42 41 40 beneath and close to the flat portion 33 of the cross-guide when the device 34 is in the locked position, so that when it is rotated to the dotted position 34', Fig. 8, the said parts 42 41 40 will still be behind and beneath the foot-rest.

lVhen the rounded part 32 does not extend the whole length of the cross-guide 31, as shown in Fig. 10, it should have such length that the spring 41 will press upon it with the same force at any of the positions occupied by the .device 34 when rotating about the circular bearing 36, for then the spring 41 will not only prevent the device 34 from sliding along the bar 31 when on the bearing 36 and in the position 34', Fig. 8, but. will assist the weight of the knob 35 in preventing rotation on account of a jar when the locking device 34 lis in the position shown in Fig. 9.

A locking device, as a spring-catch, might be attached to the side wall 51 or the side frame-piece 53 in such manner that the stem 37 could be pushed under it, and the sliding device 34 be thus locked and prevented from rotating about the bearing 3 8; but the means illustrated in Figs. 8 and 9 are of more general application and believed preferable. The device shown in Figs. 8 and 9 is also adapted to be operated by the foot of thedriver when seated.

The part a of the device 34 extends somewhat away from the cross-guide 31 and has aA vthe bearing 36, when the device 34 may be rotated forward and locked by the driver inserting the toe of his boot under it and turn'- ing it upward and forward.

Vhen both of the locking devices 34 are locked in their respective corners,they are out of the way of the feet, and the projecting parts a are then in position to serve as stops to prevent the feet from slipping off of the ends of the foot-rest and striking the painted side walls 51.

While the method of making the ends of the cross-guide 3l 36 (shown in Figs. 1 and 4) might be least expensive, there is no provision for replacing a new locking device 34 in case of breakage. To provide for this and to enable all of the parts of the cross-guide and also the main parts of the locking device 34 35 37 to be cast, if so desired, the construction shown in Figs. 9 and 10 may be used. There the bearing 36 is extended into a projection 44, on which a screw-thread is cut. A boss 45, tapped for the reception of the screw end 44` is formed on the end of a support 46, Fig. 10, having a boss 47, with a hole for a small bolt, by means of which the support 46 is secured to the body side piece 53.

In Figs. 1 and 4 a stationary step 26 is shown supported by means of an a'rm 25, projecting from and forged integral with the forward brace 12 of the pyramidal frame and so as to be midwaybetween the movable step 9 when in position for use,'and the stationary step 29, Fig. 4, placed on top of the side bar 30. When the movable step 9 is elevated and turned under the body, the pyramidal frame 1 11 12 and the stationary step supported thereby would have a better appearance if the stationary step were on a level with the boss 2, as shown dotted at 23, Fig. 1, where the supporting-arm 27 is shown dotted also. In Fig. 13 a similar step 66 is shown in dotted outline projecting from the boss 2. rlhe stationary step supported by the pyramidal frame may be placed at any suitable elevation which will best divide the distance between the movable step 9 and a stationary step supported independently from the side bar 30 or the body. Since the step 26 corresponds in position and elevation to the usual pendent step supported from the side bar or the body, it may be omitted in the construction of the said pyramidal frame or of any of the step-supports set forth, as in Figs. 5 and 6, and may be supported in the IOO IIO

usual manner in a position such as to make its use in connection with the movable step 9 convenient.

Figs. 11 and 12 show a modification of the movable-step-supporting frame, where, while the construction is varied,.the principle remains the same. Here the

braces

11 and 12 are shown continuous and with a boss 59 Welded (or otherwise suitably secured) to them at t-heir juncture. The boss 59 has a central hole, through which the lower end of the up right l passes and in which it is secured. The lo-wer portion 60 of the brace 11 is bent upward and around the boss'backward and inward, something like a spiral, to a point 63, whence it may be continued straight to the boss 14, by which it is attached to the bodybottom. The boss 4, to which the step-shank 8 is attached, is plane on its lower end, and the shank 8 projects outward sufficiently before bending downward to permit of an inclined face 62, Fig. 12, being given to its under side, such as to correspond with the inclined upper surface of the part GO of the brace 11, so that the shank 8 may slide upon the said portion 60 when the movable step 9 is turned from its outermost to its innermost position. This construction also permits the fore wheel to push the movable step out of its wayin turning inward. \Vhen the shank V8 has been slid along the curved portion 60 of the brace l1 tothe point 63, it will remain in contact with the brace 11 from the point 63 until it reaches its elevated position 8', Fig. 12, when the boss 4 is drawn upward by the lifting-chain. (Shown in Figs. 1 and 4.) When the movable step is dropped, the shank 8 will slide in contact with the brace 11 and be guided by the curved part 63 60 to position. When the movable step 9 is in position for use, the side of the shank 8 rests against a lug or projection 61, which corresponds to the stop-face 5 of the boss 2 in the former modification, and, like the face 5, it, too, may be replaced by a surface inclined so as to guide the shank 8 backward to a proper l seat.

In bothxthemodifications of a pyramidal frame shown, as well as where an upright only is used, a stationary inclined surface is formed upon a part or' parts of the movable step-support as a means of guiding the movble step to position for use, and an abutting surface is formed upon a part or parts of the same as a means of stopping the rotation of the step and forming in connection with the said inclined surface a suitable seat for corresponding parts of the movable step, and whereby provision is had for moving the said step out of the way of the fore wheel or of enabling the fore wheel to automatically push the step out of its way when it is turned in against or under the vehicle-body.

It is not intended that the movable step set lforth shall be used each time any person gets into or out .of the vehicle, as gentlemen hav ing good use of their limbs need not use it at all, since the stationary step 26 will be found as convenient as were it the usual stationary step for which it is a substitute; but the movable step is always ready for use and willbe found of great convenience and even indispensable for women, children, and infirm persons.

The movable step is especially convenient and desirable for use upon a buggy having a top extending well forward, as when the top of a buggy is up and the stationary steps are arranged, as was previously necessary, it is often quite inconvenient even for supple grown persons to get into or out of the buggy.

Vhen the vehicle-supporting springs are placed lengthwise and directly under the side bar 30, they will not extend below the side bar at the location of the upright 1, and when they are placed crosswise of the body they are or may be so located as not to interfere with any of the parts of the movable step or its connections, so that there need be no difficulty in attaching my improvements to various styles of vehicles.-

The modification of a movable vehicle-step and supports herein specifically shown and described has a stationary upright and a per-4 forated boss; but the inclined guiding-surfaces described could be formed on the parts and perform the same functions were the stepboss connected to the upright and the supporting boss perforated, as when the upright 1 is arranged to slide within the boss 2.
