Application tiled May 1'7, 1900.

To' all whom it may concern.-

Be it known that 1, CONRAD MILLER, a citizen of the United States, residing at Lead'- ville, in the county of Lake and State of Colorado, have invented certain new and useful Improvements-in Sleds; and I do hereby declare the following to be'a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in sleds, but more particularly relates to that class of sleds designed for the transportation of heavy freight and the like.

Heretofore the sleds ordinarily employed have been made of wood 5 but the life of these has generally proved short, and in transporting heavy freight such sleds were subject to frequent breakage. It is therefore the object of the present invention to provide a sled which is constructed entirely of steel or equivalent material, with the possible exception of the bolsters and pole, by which the life of the sled is greatly prolonged and liability to fracture reduced to a minimum; and, further'- more, the invention contemplates in the construction of the sled such an arrangement of parts that the latter may be readily and quickly assembled, that'when so assembled the sled will possess high qualities in point of utility andV strength,"and that in the use of the sled loading and unloading of the same may be executed with ease and rapidity.

With these'and other objects in view', which will appear as the nature of the improvements is better understood, the invention consists,

- substantially, in the novel construction, combination, and arrangement of parts, as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended'claims.

In the drawings, Figure l is a side elevation of a pair of the sled-runners; Fig. 2, a top plan view thereof; Fig. 3, a top plan view of the entire sled on a reduced scale; Fig. 4, a front elevation thereof, partly in section; Fig. 5, a rear elevation, also partly in section; Fig. 6, a transverse sectional view on the line 6 6, Fig. 4; Fig. 7, a-longitudinal sectional viewof the reach; Fig. 8, a similar viewof the roller therefor; Fig. 9, a top plan View of said roller; Fig. 10, a top plan view, partly c Serial No. 17,050. (No model.)

pole-roller; Figs. 13 and 14, end and side elel vations, respectively, of the saddle to which the Aknees are. connected.

Referring to the drawings, and more particularly to Fig. 3, the numeral 1 designates the front pair of runners, 2 the rear pair, and 3 the reach connecting the, same. These parts are formed entirely of steel or equivalent material, and by referring to Figs. 1 and 2 the construction of the runners will be more clearly seen. In these figures, 4 designates the runner proper, which is of inverted -T shape, and riveted or otherwise suitably fastened to the under face of said runner proper is a shoe 5, preferably of flat rolled steel. A knee 6 is arranged at a point substantially midway the ends of the runner 4, which knee has its lower end bifurcated, as at 7, and fittingwithin said bifurcated end is a saddle 8, ofV inverted-U- shape in cross-section. The saddle 8 straddles the vertical flange of the runner 4, as is clearly seen in Figs. 4 and 5, and has its ends converging upwardly, whereby a comparatively long bearing-surface is formed at the lower edge, and said surface rests upon and extends longitudinally of the horizontal iiange of the T-runner 4. The saddle 8 further reinforces the vertical iiange of the runner 4, so that the latter is greatly strengthened at the point of connection of the knee 6 therewith. A pivotal bolt 9 or its equivalent passes through the sides of the knee 6, the saddle 8, and the vertical fiange of the runner, by means of which the runner is capable of oscillatory movement on the knee, and arranged so as to extend over the tween the runner and the brace and eectually holding the latter. A pair of tie-rods 12, however, is arranged one at each side of the knee 6, which tie-rods are also secured at their lower ends to the runner 4, as at 13, and said rods have their upper ends screw-threaded and projecting through the body portion IOO of the brace 10. Mounted upon the threaded end of each of said rods is a pair of bindingnuts 14, disposed, respectively, above and belowr said bodyv portion of the brace 10, and thus it is obvious that when said nuts are screwed tightly upon said body portion the rods 12 provide an eective support for the latter. Each of the knees 6 is provided at its upper end with guide-lugs 15, between which the body portion of the brace 10 lies, and it is therefore apparent that said lugs while permitting the brace to follow the movements of the runner 4 during its oscillation will render the brace incapable of lateral movement. For limiting the oscillatory movement of the runner 4 a pair of L-shaped stops 16 is employed, and one of said stops is arranged at each side of the knee 6, the stops 16 being secured to the under side of the body portion of the brace 10 by bolts 17 or their equivalent and the upper ends of the tie-rods 12. If desired, the stops 16 may be adjustably secured to said brace 10 for varying the range of oscillation of the runner.

For the purpose of connecting together the runners of each pair and also providing a firm support for the bolsters of the sled a sectional beam 18 extends transversely relative to said runners, and said beam comprises a pair of parallel members 19, formed of channel-steel or equivalent material and disposed at opposite sides of the knees 6. The latter are recessed at the upper portions of their front and rear faces, as at 20, for the reception of the members 19, and it will be noted that the upper walls of said recesses are flared, the'upper flanges of the members 19 being correspondingly shaped, so as to snugly fit the recesses 20. By reason of this construction the members 19 have a stiff and durable connection with the knees 6, and for maintaining such connection bolts 21 or their 'equivalent are passed through the members 19 and the knees 6 and secured therein. The knees of each pair of runners are also provided at their upper ends with inwardly-extending projections 22 in order that the ends of the beams 18 may be thoroughly supported, and disposed between A the members of each beam, at the center thereof, is a tubular anchoring-iron 23, bolted or otherwise suitably fastened in position. The iron 23 is designed for stiffening the beam 18 and as employed with the front pair of runners receives the king-bolt, hereinafter referred to, and provides a wearing-surface therefor. Bolsters 24 are mounted upon the supportingbeams 18, which bolsters are preferably of wood, and the bolster of the rear runners, as seen in Fig. 5, is rigidly secured in position by bolts 25 or their equivalent, the front bolster being pivoted toits supporting-beam by a king-bolt 26, the lower end of which passes through the anchoring-iron 23, as previously stated. Each of the bolsters 24 has upon its upper face a pair of standards 27, having at their lower ends inwardly-extending feet 27', and said feet are designed to lie beneath the box of the sled when the latter is placed upon the holsters" 24.* 'l v The foregoing description relates solely to the construction of the runners; but in order that the same may be connected together the reach 3, previously referred to, extends longitudinally from the supporting-beam 18 of the front pair of runners to the forward ends of the rear runners, at which point said reach is connected to the rear runners in a manner to be presently stated. The forward end of the reach, however, is coupled to the turninggear 28 of the sled, and by referring to Fig. 6 theconstruction of said gear is clearly seen, the same comprising a lower plate 29 and an upper plate 30, Working thereon. The faces of each of said plates contiguous to the-beam 18 and the bolster 24 are-recessed for therecept-ion of said parts, and to the latter said plates are secured in any desired manner. It will be noted, however, that the lower plate 29 is provided with a forwardly-projecting arm 31, to which may be attached a chain and spring or otherV suitable device for maintaining the pole of the sled normally elevated, and at its rear is also provided with a semicircular extension 32, in which is formed a segmental guide-slot 33. The upper plate 30 is likewise provided with a rearwardly-extending arm 34, which works upon the semicircular extension 32, and said arm 34 has at its under side a depending guide-lug 35, which lies and works within the guide-slot 33. The arm 34 is provided at the lug 35 with an aperture 36, through which a coupling-pin 37, carried by the forward end of the reach, is passed, and .it will be seen that the lug 35 provides a wearing-surface for the pin 37, and thereby prevents the latter contacting with the edges of the slot 33, thus obviating the formation of irregularities therein incident to the strain upon the coupling-pin 37.

The reach 3 is formed of channel-steel or equivalent material, as seen in Figs. 7 and 8, and said reach is provided with a downwardlyextending offset 38, by means of which the rear end of the reach is positioned in a lower plane than the forward end thereof. Swiveled to the forward end of the reach 3 is a coupling-head 39, the forward end of which is forked and connected by means of the pin 37 to the arm 34 of the upper plate 30 of the turning-gear, thereby embracing the rearwardly-extending portions of the latter, but permitting the lower plate 29 and its parts to follow the movements of the front pair of run-v ners in turning, and formed integral with said forked end is a rearwardly-projecting shank 40, having at its free end an enlarged head 41. The shank 40 is of less diameter than'the forked end of the head 39 and is circular in cross-section, and embracing said shank is a sectional clamping-collar 42. The latter comprises an upper member 43 and a lower member 44, fitted, respectively, to the upper and lower sides of the shank, and said upper member lies within the forward end of the reach.

Bolts 45 or their equivalent are employed for detachably connecting together the members of the collar 42 and at the same time maintaining them in clamped relation to the shank 40 and the reach 3; but for further securing the upper member 43 in the reach horizontally-disposed pins 46 are inserted at the sides of the latter into said member. By the construction described it will be seen that each pair of the runners is capable of movement independent of the other, as when passing over inequalities in the road-bed, and it will thus be obvious that no twisting strain whatever is exerted upon the connection between the reach and the front pair of runners during such movement.

The numeral 47 designates the reach-roller, which is designed for yieldingly connecting the reach to the rear pair of runners, and said roller comprises a pair of plates 48, preferably of cast-steel, arranged in superimposed relatoin, but spaced from each other in order to receive the rear end of the reach 3. The inner face of each of said plates is provided at its edges and center with ribs 49, and fitted between said ribs at each end of the plates is an attaching-spindle 50. The spindles 50 are removably secured between the plates 48 by means of bolts 51 or their equivalent, whereby when said spindles have become worn the same may be easily and quickly replaced at small expense and without the necessity of employing an entirely new roller, and said spindles pass through the forward ends of the runners proper, 4, of the rear pair. At the sides of the vertical flanges of said runners proper and at the points through which the spindles 50 pass are arranged bearing-eyes 52, which eyes are adapted to reinforce said vertical iianges and also provide wearing-surfaces for the spindles 50, and it will be observed that the latter pass through and lie within said eyes and are secured therein by any suitable means. Rearwardly-diverging braces 53 are suitably connected to the reach for stiening and strengthening the same, and the rear ends of said braces are connected to the spindles 50 exterior of the runners proper, whereby said spindles are highly strengthened. As before stated, the rear end of the reach 3 is received between the plates 48 of the roller 47, and said reach lies between the central ribs 49 and is secured therebetween by bolts 54 or their equivalent.

Apole 55 is arranged at the forward end of the front pair of runners, said pole being preferably of wood, and the same is attached to said runners by means of a roller 56. The construction of the latter is precisely the same as the roller 47 and secured in also the same manner as said roller 47, and for strengthening the pole rearwardly-diverging braces 57 are employed, which braces are attached to the pole-roller similar to the braces 53. The forward ends of said braces, however, extend along the sides of the pole 55 and are secured thereto.

From the foregoing it will be seen that the herein-described invention provides a sled which embodies high qualities in point of durability and strength, and especial stress is laid upon the construction of the runners, whereby a perfect distribution of resistance to the load is obtained. This is due to the y fact that the load is carried on the runners by contact with the saddles 8, through the knees 6 and beams 18, and as the saddles 8 extend between the tie-rods 12, which have their upper ends fastened in the truss-braces 10, the load will hang upon said truss-braces and cannot sag the runners proper without stretching the same or buckling the truss-braces. Moreover, the nuts 14 provide means to take up wear and maintain the runners straight under any load.

While a preferable embodiment of the invention is disclosed, it will of course be understood that the invention is not limited thereto, but the right is reserved to modify or vary the same as falls within the spirit and scope thereof.
