ROLLERj-SKATE.

SPECIFICATION forming part of Letters Patent No. 499,052, dated June 6, 1893.

Application filed March 10I 1892. Serial No. 424,404.' (No model.)

To all whom it may concern:

Be it known thatl, CARL STORLA, of Belford, in the county of Aurora and State of South Dakota, have invented a new and Improved Roller-Skate, of which the following is a full, clear, and exact description.

My inventionA relates to improvements in roller skates, and the object of my invent-ion is to produce aroller skate which may be conveniently and rapidly propelled by the weight of the skater, this being effected by simply shifting the weight from one skate to the other, to provide means for tying the skates together so that they will form a vehicle to safely carry the rider, to produce a convenient steering mechanism for the skates, and to provide the skates with compartments adapted to hold the steering mechanism, wrenches, or other articles when necessary. l

To this end, my invention consists in a roller skate, the construction of which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a vertical longitudinal section of the skate embodying my invention, on the line 1--1 in Fig. 3. Fig. 2 is a rear end view ot the same. Fig. 3 is abroken sectional plan on the line 3-3 in Fig. 1. Fig. 4 is a vertical cross section through the skate body, on the line 4-4 in Fig. 1. Fig. 5 is abroken detail longitudinal section of the steering tubes and their connections. l Fig. 6 is a detail perspective view of the tie bar used to connect the steering gear wheels of two skates. Fig. 7 is a detail perspective view of a cross bar used to fasten the skates together. Fig. 8 is a detail side elevation of the releasing lever used to prevent thebell crank lever from engaging the ratchet wheel except to drive it; and Fig. 9 is a plan view on a reduced scale of two skates secured together.

The skate is provided with a box-like trame 10, which is open on top, and the frame has at one end a box 11, adapted to receive a Wrench, oil can, or other necessary articles, and the box is closed by a swinging lid 12, the front edge of which juts over the main portion ofthe box 10. At the front end of the skate body is another compartment 13,

`forms of the skate as hereinafter described.

On one side of the skate is a box or compartment 15, extending the entire length. ofthe `skate body, and which is adapted to receive the collapsed steering rods when theyl are not in use.

The skate is mounted on wheels 16 and 17, arranged at the front vand rear part thereof, the wheels being fixed to square axles 18 and 19, and the front axle 18, being journaled in the depending hangers 20, formed on the ends of the yoke or table 2l, which is pivoted to the front under side of the body or frame 10, as shown at 22 in Fig. 1. Rollers 23, are pivoted on the under side of the frame or body 10, and are arranged to bear upon the yoke or table 21,'so that the latter may turn very easily. The rear axle 19, is journaled in hangers 24, which are secured to the under side of the frame or body 10, and the wheel 17 is generally arranged a little oft the center, that is, nearer the outside of the center than the inside, the front whee'l 16 being generally arranged a little nearer the inside of the skate, though heels 1G and 17 can be brought to right or left at pleasure by sliding on axles 19 andl 18 and fastened iirmly to said axles by means of screws. A supplemental hanger 24 is secured to the body opposite the hangers 24, so as to t'orm a bearing for the axle 26 of the ratchet wheel 25, and this ratchet wheel is driven by mechanism held in the frame or body 10 as described below, and is provided on its inside, that is, on the inner side of the rim, with cogs 27, which engage the teeth of a pinion 28, secured to the axle of the rear wheel 17. It Will thus be seen that the movement of the ratchet wheel in one direction will turn the pinion 28, and drive the wheel '17, thus propelling the skate. The ratchet wheel 25 is turned by a bell crank lever 29, which is pivoted in the skate body and extends downward through a slot 30 in the same, the lower end of the vertical arm of the bell crank being formed into a pawl 3l, which engages the ratchet wheel, as shown in Fig. 1, and the other arm 32 of the bell crank IOO being made to extend forward into the skate body so as to engage tripping mechanism as hereinafter described. The bell crank 29, is secured to a transverse rod 33, the ends of which are held to slide in vertical grooves or slots 34 in the sides of the frame or body 10, and the rod is journaled in lugs or ears 35, on the under side of a vertically-movable platform 36, which is mounted in the frame or body 10, and is normally pressed upward by the spiral springs 37, arranged beneath it. and adjacent to its four corners. The upward movement of the platform 36, is limited by the inwardly jutting ends of'thelid 12 and cover 14 shown in Fig. 1. Above the platform 36, is a second platform 38, which is hinged centrally to the main platform, as shown at 39, and this enables the foot of the skater resting upon the platform 38, to have a very easy movement as the platform may tilt to con form with the varying positions of the foot, according as the foot is advanced or retracted raised or lowered. The platform 38 may be provided with any suitable straps or fastening mechanism to attach it to the foot of a skater, as shown by dotted lines in Fig. 1. It will be seen that when the skater presses down upon the platforms 38 and 36, they will be depressed, and the bell crank 29 will turn the ratchet wheel so as to propel the skate forward, and when the weight is removed from the platforms the springs 37 will throw the platforms back to their normal positions.

The following mechanism is used to prevent the bell crank from touching the ratchet wh eel during the upward movement of the platforms so as not to interfere in any wise with the free motion of the skates. A tripping lever 40, is pivoted on a stud 4l on the under side and near the forward end of the platform 36, the lever having its rear end pressed by a spring 42, which is secured on a wire or rod 43 on the under side of the platform, so that the enlarged rear end 44 of the lever will extend into the path of the horizontal arm 32 of the bellcrank lever 29. This enlarged end 44, is inclined on one edge and on the under side, as best shown in Fig. 4, so that when the arm 32 is pushed upward it may pass the lever. The forward end of the lever 40, projects through a slot 45 in one Wall of the compartment 13, and the lever is provided with a roller 46, which turns by frictionally engaging the wall of the slot 45, and the front end of the lever 40 is adapted to engage a shoulder 48, on the under side and at the free end of a releasing lever 47, which is pivoted transversely on the inner wall of the compartment 13, as best shown at 49 in Fig. 4, and on the under side of the releasing lever 47, is an arm 50 which extends diagonally downward and serves as a keeper which serves to hold the lever 47 and tripping lever 40 in the proper relative positions. This is best shown in Fig. 4, the tripping lever when it moves down, strikes the arm 50 and carries the arm and lever 47 into the position shown by dotted lines in Fig. 8, and when the tripping levermoves back it comes into position to again engage the shoulder 48 and the lever 47.

Secured to the bottom of the body or frame 10, and extending upward within it is a post 51, which is arranged in the path of the arm 32 Of the bell crank lever 29, and when the le ver is pushed down, the post 51, by engaging the arm of the lever, tilts the lever so as to withdraw the pawl 31 from the ratchet wheel. Supposing the parts to be in the position shown in Fig. 1, but with the end 44 of the lever 40 beneath the arm 32, then when the platforms 38 and 36 are pushed down,the releasinglever 47 tilts the tripping lever 40, and throws the end 44 out of the path of the arm 32, and the pawl 3l springs into engagement with the ratchet wheel so that the descent of the platforms turns the ratchet wheel. When the platforms have advanced to nearly the lower end of' their stroke, the arm 32 strikes the post 5l, and is pushed upward, and the forward end ofV the arm passes the inclined side or edge of the thickened end 44 of the tripping lever 40, and the tripping lever springs back to place, thus passing beneath the under side of the arm 32, and holding the pawl 3l out of engagement with the ratchet wheel, when the pressure is removed from the platforms, the springs 37 raise them to their normal position.

At the front and rear ends of the skate are recesses 52, which are adapted to receive the ends of cross bars 53, and these may be used to connect two skates so as to hold them rigidly together, the cross bars being held in place by keys 54, which extend through holes 53 in the cross bars and through corresponding holes in the end of the skate body, as shown in Fig. l. At the front end of the skate is a Vertical rod 55, of square cross section but which turns in cylindrical bearingsv the lower end of which projects through a platform 56, formed by a prolongation of the bottom of the skate body, and the upper portion of the rod is journaled in a lug 57 at the top of the skate body. The rod is held down by a swingin g latch 58, which is recessed on its inner edge to lit the rod, as shown in Fig. 3, and which is adapted to engage a notch in the rod, this latch being pivoted on the under side of the lug 57. The upper end a of the rod 55 is hollow so as to receive the inner steering rod 59, the rod is of circular cross section at a point where it is engaged by the latch so as to permit the free turning of the rod which is held to it bya spring pressed pin 60, which projects through the outer wall of the rod 55, and into a notch in the rod 59, as shown in Fig. 5, and the upper end of the rod 59 is enlarged to form a head 6l, which is held in the lower end of a tube 62, the upper end of the tube having a lever 63 pivoted thereon, and this lever is fulcrumed, as shown at 64, on a Harige 65 at the upper end of the upper square exterior steering tube 66, which tube is held by spring catches 67,

eeaos e to a lower square section 68 of the `tube having perforations 67 to engage the catches, this lower section resting on a rest 69, which is fastened upon the upper end of the rod 55. A spring 70 is arranged between the rest 69 and a sliding sleeve 7l, which sleeve is secured to the rod 55, by the same spring pressed pin 60 which secures the rods 55 and 59 together, the spring pressed pin having its outer end fixed to the sleeve 71, and its inner end adapted to extend through a notch or hole in the sleeve and into a slot 71a in the shaft 55, as shown in Fig. 5. The spring 70 pushes the sleeve 71 downward to its seat so as to cause the gear wheel on its lower edge to engage the locking plate, as described below, and the slot 71a permits the necessary movement of the sleeve when it is raised to throw the gear wheel out of engagement with the locking plate. The upper end of the steering tube 66 is provided with a lever 72, which extends outward and serves as a steering lever when both hands are used, as the lever 72 may be grasped with one hand and the lever 63 with the other. When only one hand is employed to steer the skates the lever 63 is used. The section 68 of the steering tube may be provided with several holes 67 a to engage the spring catches 67, so that it may be adjusted longitudinally, and by releasing these catches and the spring catch 60, the tubes 66 and 68, and the tube 62 and rod 59 may be collapsed, that is, telescoped, so that the tubes will occupy but little space, and they may then be packed within the box or compartment 15, which is shown clearly in Fig. 3.

The object of the sliding sleeve 7l and the lever mechanism for arranging it, is to enable the steering mechanism to be thrown in or out of gear as will be described below. At the lower end of the sleeve 71, and secured thereto, is a gear wheel 73, which is adapted to engage the teeth 74. on one edge of a locking plate 75, which plate is pivoted on the cover 14, as shown at 78 in Fig. 3, and a spring wire 79, is secured to the top of the locking plate, one end of the wire near the free end of the plate terminating in a pin 80, which is adapted to extend downward through the plate and into a hole in the cover 14, so as to hold the plate in a fixed position, and when the locking plate and the gear whee173 are in engagement, it will be seen that the steering mechanism cannot be turned. By swinging the locking plate backward upon its pivot, however, the gear mechanism is left free to turn and the skates may be 'easily steered by means of the handle or lever 63.

On the lower end of the rod 55, and on the under side of the platform 56, is a gear-wheel 8l, which meshes with a gear wheel 82 fixed to the pivot 22 of the yoke 21, so that by turning the rod 55 and the gear wheels 81 and 82, the yoke 21 and the forward wheel 16 may be turned, thus steering the skate. The steering mechanism -is only to be used however when two skates are united, and to this end, the gear wheel 81, is provided near one edge with a tube 83, which registers with a curved slot 84 in the platform 56, and the tube is adapted to receive the studs of a tie bar as described below. The front end of the platform56, is` bent under as shown at 85 in Fig. l, so as to form a shield for the gear wheel 81. To connect the gear wheels 81 of two skates, a tie bar 86 is used, shown in detail in Fig. 6, which tie bar comprises a bar 87, having pivoted at one end a stud 88, and the opposite member of the tie bar consists of two parallel bars 90, adapted to embrace the bar 87, these bars having also at one end a stud 88 and the bars are slotted at 91, so as to receive screws 92, by means of which the length of the tie bar may be regulated. To connect two skates the studs 88 are inserted in the slots 84, and their free ends are pushed into the tubes 83- of the gear wheels 81, and consequently, when one gear wheel is turned the other gear wheel will be turned to the same extent, and the forward wheels 16 of the two skates will move in unison, so that the two skates may be very nicely steered.

The skates are operated by simply shifting the weight from one to the other. When the weight is thrown upon the platforms 38 and 36, they operate the ratchet wheel, and by means of the gear mechanism described above propel the skates, and from the foregoing description it will be seen that by shifting the weight often enough, the skates may be made to run very rapidly.
