TRACTION-INCREASING MEANS FOR TRACTION ENGINES.

Application filed August 13,1923. Serial No. 657,074.

To all whom it may concern:

Be it known that I, HARRY V. ORosLEY, a citizen. of the United States, residing at Roundup, in the county of Musselshell and State of Montana, have invented new and useful Improvements in Traction-Increasing Means for Traction Engines, of which the following is a specification.

The object of my said invention is the provision of traction increasing means susceptible of being readily applied to and removed from traction engine wheels, and this in such manner that the wheels are not weakened appreciably. and the pressure applied to the traction increasing means will not tend to loosen the connection between said means and the wheels; the said connection being of such a character that the traction increasing means can be put on or removed without raising the engine.

The laws of many States inhibit the passage of traction engines over bridges and paved highways unless the traction increasing means of such engines are removed, and hence the ready removal of traction increasing is a desideratum.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification Figure 1 is a general view of a section of traction increasing means constructed in accordance with my invention.

Figure 2 is an edge elevation of the same.

Figure 3 is a plan view showing the inner side of said section. 1

Figure 4 is an enlarged detail plan showing the outerside of a portion of the section and one lug carried thereby.

Figure 5 is an enlarged detail longitudinal section taken in the plane indicated by the line 55 of Figure 4: and showing the relative arrangement of one lug and one carrying strap, and the manner of connecting the lug to the strap and bracing the lug by the strap.

Figure 6 is a general view of a modification that is resorted to when the width of a wheel requires two rows of lugs.

Figure 7 is a detail longitudinal section on the line 7-7 of Figure 6.

Figure 8 is a detail enlarged cross-section on the line 8 8 of Figure 6, and showing the manner in which each lug of the modified construction is connected to two carrying straps.

Similar numerals designate corresponding parts in Figures 1 to 5 towhich reference will first bemade.

I would have it understood that my novel traction increasing means comprises several arcuate sections such as shown in Figures 1, 2 and 3, the said sections being arranged end to end-around the peripheral portion of a traction wheel and being connected-at their ends to said peripheral portion by means of bolts or other appropriate fasten-- ing devices. The said sections are identical in construction and therefore a detailed description of the one shown in Figures 1 to 8 will suffice to impart a definite understanding of all. The said section includes two arcuate carrying straps 1 of appropriate metal arranged in parallelism and having by preference apertures 2 adjacent to their ends for the passage of connecting bolts. The section also comprises spaced traction affording lugs 3 which are also formed of appropriate metal and arespaced apart and are arranged by preference at acuteangles to the carrying straps L The said lugs 3 are of right angle form in'cross section, and

each includes a base portion 5 arranged against the inner sides of the straps 1 and an outwardly extending portion 6 apertured at 7 and snugly receiving the straps 1; the base portion being fixedly connected to-the carrying straps 1 by rivets 8 or other appropriate means. By virtue of the said construction and relative arrangement of straps and lugs it will be manifest that each lug of itself is in a measure connected to and held on the carrying straps with the result that the major portion of the-strain incident to the use of the traction increasing means is taken off the rivets 8 or other connecting means.

It will be manifest from the foregoing that each of the sections described includes a number of lugs 3, and from this it follows that the traction increasing means complementary to a traction wheel may be expeditiously and easily applied to and readily disconnected from the wheel.

The modification shown in Figures 6, 7

and 8 is designed for use on comparatively ,wide wheels, and is made up of three straps 1 similar to the straps 1; and two rows of lugs 3 similar'to the lugs 3,- and connected to and relatively arranged on the straps l in the same manner that the lugs 3 are arranged on and connected. to the straps 1. It will be observed however, that in the modified construction-the lugs -3" of one row alternate with the lugs 3 of the other row; also, that the inner portions of the lugs of the two rows are arranged in lapped though spaced relation, and that the lugs of the two rows are so disposed that the lugs of one row extend at an .anglewith the lugs of the other row so that each pair of adjacent lugs in the two rows form substantially obtuse angles. Manifestly this construction affords great traction to a wide wheel.-

Like the embodiment shown in Figures 1 to 5, the embodiment shown in Figures 6 to 8 is susceptible of being readily applied to and removed froma traction wheel for the reasons hereinbefore indicated.

' I have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present-and preferred embodiments of my invention in order-to impart a full, clear and exact understanding of the said embodiment-s. In do not desire, however, to be understood as confining myself to the specific construction and relative arrangement of parts inasmuch as in the future practice of the invention various changes and modifications may be made such as fall within the scope of my invention as defined in my appended claims. .1

Having described my invention,- what I claim and desire to secure by Letters-Patent, 1s:-

1. In traction increasing means for traction wheels, an arcuate carrying strap in combination with a lu'g carried by and intersecting the strap, the said lug being of angular cross section and having a base portion attached to the strap and also hav ing an upwardly extending portion with an aperture snugly receiving the strap;

2. In traction increasing means for traction wheels arcuate carrying straps arranged in parallelism, and spaced. lugs arranged on and at an angle to the straps; the said lugs being of angular cross-section and each having a base portion arranged at the inner sides of and connected to the straps and also having an outwardly extending portion with apertures snugly receiving the straps.

3. Traction increasing means for traction wheels comprising spaced arcuate carrying straps in parallelism, and spaced lugs carried by and on the straps and disposed at acute angles to the straps each of the lugs including abase portionarranged at the inner sides of andconnected to the straps and an outwardly extending portion disposed substantially at right angles to -the base portion and: having in itsiinner portion. apertures snugly receiving the straps whereby the lug is held of itselfon the straps 1 i p 4. Traction increasing means for traction wheels comprising three arcuate spaced straps in parallelism, and two rows of lugs carried by and on the straps; the, lugsbeing of angular form in cross-sectionand the lugs of each row intersecting the intermediate strap and one of the outer straps, and the lugs of the two rows being disposed at obtuse angles to each other; and j each lug having an inner portion arranged at the inner side of two straps and connected thereto and an outer portion with apertures snugly receiving the straps.

In testimony whereof I affix my signature.
