SLED

Filed Feb. 28, 1951 Patented ug. 2, 1932 nuire-n STATES PATENT ortica- TORVALD d. JOBAGrIIENSEN,v OF RANKLIN SQUARE, AND OLAF K..JORGENSEN, OF GARDEN' CITY, NEW YORK SLED Application filed February 28,1931. Serial No. 519,033.

This invention relates to new and useful improvements in sleds, and has for one of its objects the provision of a vehicle of the kind described, wherein the constituent elements are so coordinated structually as to assure improved results with material which is easy to manufacture, and which is also easy to maintain in efhcient working condition.

Another object of the invention is the provision of a sled wherein relatively movable body and runners are so arranged that the latter, while rigid for fore and a movement, are yieldable vertically, in order to resiliently support the weight of the load carried, particularly while the vehicle travels over obstructions or an uneven course` A further object of the invention is the provision of steering means, which, having a pivoted runner and a movable post to carry the same, also include a control device for the post, so that the latter may be set for predetermined movement, at least in one direction, or to guide the vehicle on a straight course.

l,Vith the above and other objects in view, this invention consists of the novel features of construction, kcombination and arrange ment-s of parts, hereinafter fully described7 claimed and illustrated in the accompanying drawing forming part of this specification, and in which similar characters of reference indicate corresponding parts in all views, and in which:

Figure 1 is a lateral elevational view of our improved sled;

Figure 2 is a front elevation;

`Figure 3 is a top plan view;

Figure l is an enlarged sectional detail view taken on the line i-4 of Figure 3; and

Figure is an enlarged section, talren on the line 5 5 of Figure 1.

ldeferrin` more particularly to the drawing by reference characters, designates a body, preferably of wood, which may be made in two attachable sections 11 and 12, for economy of material.

rlhe body 10 is provided with a seat 13, which may have supports, as at 14, and with a foot board or rest 15.

Attached as by screws 16 to the body 10 is a pair of hinge plates 17, 18; and to a steering post i9, by like screws 20, is attached a pair of mating hinge plates 21, 22, so that on operation'of a handle bar 23 of the post the latter is swingable about the axis of pins 24 55 of the hinges for changing the position of the runner 25 to direct the movement of the sled. This runner is pivoted at 26 for movement in a vertical `plane to yieldably meet obstructions.

A rear runner includes a pair of like niembers 27, which are attached by a tiefbar 28, and on this barare xedly mounted the lower plates of hinges 29, 30, the upper plates of which are rigidly carried by a cross-bar 31 of 65 the body 10. Lilie lateral supports 32 additionally'hold this crossbar rigid with the section 11. l

In the normal travelling position, as shown, the bars 28 and 31 are forwardly s aaced apart, 70 so that as a runner 27 meets an o stacle said runner tends to move upwardly about the pivot pins of the hinges 29, 30. A plate 33 is centrally attached tothe bar 31 by screws 31, or the like, and the bar 28 has an aperture 75 3e therein.

vSaid plate isprovided with a rigid arcuate strut or support 35, and to the bar 28 is fastened a leaf or plate spring 36, the forward free end of which movably contacts with the 30 lower terminal of the strut. Said spring therefore opposes upward movement of the forward end of the runner, thereby resiliently taking the force of the impact of the runner with an obstacle, as aforesaid, instead of transferring the force direct-ly tothe body 10 The result is' that the vehicle is rendered comfortable and safe for travel. Two cush- A, ioning springs 36 and struts 35 may be used 9o in which case the same may be positioned adjacent the ends of therbars 28, 31, instead of centrally. n

In order to lock the steering gear in a se- A lected position` preferably for straight line or travel, we provide a manipulable locking rod or bar37, which is slidably positioned in a duct orrpassage 38 of the body 10.

This latter bar is, in the present instance, threaded; and threadedly mounted on the rv bar is a manipulating knob or cylinder 39, which is positioned in a suitable large aperture 40 of the said body. The locking bar is provided with an elongate groove 41, and the post 19 has therein a recess 42, which is aligned with the duct 38 when the runner 25 is directed for straight forward movement.

The wall of the body has therein a pin 43, the inner terminal of which is loosely positioned in the said groove.

On revolving the knob 39 the bar 37 is therefore slidable longitudinally in its duct for performing the locking or unlocking operation.

The runners have protective metal strips 44 thereon, and the device may be rendered more attractive by painting or otherwise finishing the samein selected colors.

Itis obvious that changes may be made in the form, construction and arrangement of the several parts, as shown, within the scope of the appended claims, without departing from the spirit of the invention, and we do not, therefore, limit ourselves to the construction and arrangement shown and described herein.

, What we claim as new, and desire to secure by Letters Patent of the United States, is:

l. A sled, comprising` a body having a support therebelow, a runner having an aperture therein for niovably receiving said support, and spring means mounted on said runner below its aperture for carrying part of the weight of said body, said spring being in contact with said support.

2. A sled, comprising in combination with a body, an elongate support having one of its ends depending below said body, means attaching the other end ot said support to said body, a runner having` therein an aperture wherein said first end is movably positioned, and spring means carried by said runner beA low its aperture, said means contacting with said first end to resiliently absorb weight of the said body.

3. A sled, comprising in combination with a body and a relatively movable runner, which latter is provided with an aperture, hinge means, including a pivot, mounted on said body and on said runner, an elongate support curved on an are having its center on said pivot and attached at one end to the body, and spring means carried by said runner and disposed therebelow for urging said support to carry part of the weight of said body, the other end of said support being movably disposed in said aperture.

4. In a sled comprising a body and having relatively movable steering post, control means for said post, which latter is provided with a recess, said body having` therein a. duct and anaper'ture, said means having athreaded rod slidably mounted in said duct and partly movable into said recess whereby to lock said post against movement, said rod
