Description
Jam 1936. N. o. PANZEGRAU STREET PLATE FOR TRACK SHOES Filed June 5, 1935 Patented Jan. 21, 1936 PATENT OFFICE 2,028,346 STREET PLATE FOR TRACK SHOES Norman 0. Panzegrau, Chicago, Ill., assignor to International Harvester Company, a corporation of New Jersey Application June 5, 1935, Serial No. 25,047
10 Claims.
This invention relates to a street plate attachinent for the track shoes used on the endless track bands in crawler tractors.
These track bands are usually made up of a 5 series of articulately connected. links, each set of which carries a track shoe plate which usually is provided with a transverse lug to increase the tractive effort of the endless shoe belt when traversing the ground. When such endless track belt is run over street pavements it is found that the lugs cut into and severely damage the pavement and that, as a consequence, laws have been passed to prohibit the operation of track belts provided with such lugs from operating on pavements.
It is desirable, therefore, that a so-called street plate attachment be provided for these shoes, so as to present a broad, flat surface that will make the lugs inoperative I for traction purposes and prevent them from cutting into the pavements. In 20 other words, such street plate will be in the form of a shield to prevent thelugs on the shoes from injuring street pavements and the like.
The main object of the invention isto provide an improved street plate attachment for track shoes employed in crawler tractors.
v Another object is to provide such a device which will be simple and inexpensive to produce and practicable in operation. I
It is another objectjto provide such a street plate attachment which can very easily be attached and detached from the shoe on the track band.
Other objects will become apparent to those skilled in this art as the disclosure is more fully made.
These important objects may be achieved by the practicable form of the invention herein chosen for the purposes of the disclosure, and in which form the street plate embodies a flat portion carrying between its ends a pair of sleeves disposed at a right angle to the flat portion and preferably welded thereto to become an integral part of the plate. One end of the plate is provided with. a corrugated groove to fit over the lug on the shoe, while the opposite end of the plate is bent at an angle to provide a leg flange, the end of which is adapted to abut'theotherend of the shoe. Bolts are passed through the plate and itssleeves and also through holes formed in the shoe for securing the plate to the shoe, all as will hereinafter more fully appear. 1
In the accompanying drawing,
Figure 1 is a plan view of a section of the track shoe belt used on a crawler tractor, showing the improved street plates connected thereto, the view being taken looking at the ground or street engaging side of the belt;
Figure 2 is a side elevational view of a section of the track shoe band showing the street plates in position with a portion of the drawing shown in section to illustrate the manner of connecting the plate attachment to the track shoe; and,
Figure 3 is a transverse cross sectional view through the track shoe band with the street plate attached, taken along the line 3-3 of Figure 2 looking in the direction of the arrows.
These track shoe bands for crawler tractors have in recent years become quite standard in construction, the same comprising, as shown in Figure 3, pairs of parallel sidebars or chain links it arranged in spaced relation with the proximate ends of one pair of side-by-side arranged links H) carrying a bushing ll passed through apertures formed in the said ends of the links, while the other proximate ends of the links have openings to receive a pivot pin l2. The side bars Ill of one pair of links overlap the ends of the adjacent pair of links, so that the sleeves II and pins l2 cooperate for pivotally connecting adjacent ends of the links in adjacent pairs in the usual manner of assembling so-called roller chain. The side bars Ill are formed with openings to receive bolts l3 for securingacross each pair of side bars Ill the track shoe M, which generally comprises a fiat plate spanning the space between the side bars Ill and extending laterally at its edges beyond the side bars, as shown in Figure 3, said track shoe having parallel side edges, near which side edges is arranged at each side, a hole l5 outwardly of the links In for a purpose later to appear. a
Each track shoe [4 adjacent one end is formed with a transversely disposed lug l6 which serves as a traction increasing grousen, This lug l6cis usually several inches deep and obviously does much damage to. pavements when operating thereover because of its digging and cutting action.
Adjacent the lug [6 the plate is formed with a curved flange end I! and at its opposite end the track shoe I4 is formed with a small curved flange end l8. From this it will be seen that the flange I8 on one shoe overlaps the flange [l on the adjacent shoe to form what is known as the overlapping type of shoe. I
The improved shoe plate attachmentis preferably made of heavy sheet metal and embodies a flat street engaging portion IQ of a width substantially equal to the width of the track shoe One end of the street plate I9 is formed with a transverse corrugation 29, which snugly fits over the free edge of the transverse lug I6 while the opposite edge of the street plate I9 is bent at an abrupt angle, as shown at 2|, to form what might be termed a leg flange that is adapted to abut and rest on the outer surface of the curved end I8 of the track shoe I4.
Opposite side edges of the plate I9 in radial alignment with the holes I in the track shoe I4 are countersunk to form depressions 22, which depressions are apertured, as shown in Figure 2, and arranged in transverse alignment, as shown in Figure 1. Fitted over these depressions 22 on the inner side of the plate I9 are respective spacer sleeves 23 having countersunk ends to fit over the depressions 22, said sleeves, as shown at 24, being securely welded to the plate I9 and around said depressions 22 whereby said sleeves 23 are securely and integrally attached to and formed as a part of the plate I9. These sleeves 23 act as supporting posts or columns and are adapted to have their inner ends fiushly arranged against the outer surface of the shoe plate It with the bore in the sleeves 23 registering with the holes I5 in opposite ends of the shoe plate I 4. A headed bolt is then inserted through the street plate I9 and the openings therein in the depressions 22, through the sleeves 23 and through the holes I5. Nuts 26 are attached to the bolts 25 from the back side of the track shoe I4 securely to attach the street plates I9 to the track shoes I4. It is to be observed that the heads of the bolts lie in the countersunk depressions 22 with the outer ends of the heads of the bolts lying flush with the street engaging surface of the street plate I9.
From this disclosure it will now be appreciated that the street plate I9 is very simple in construction and that it-can be easily attached to and removed from the track shoe I4, as desired, with a minimum of effort. The transverse corrugation 20 serves as a guard for the lug I6 and also cooperates with the lug in holding the street plate securely in place along with the bolts 25, thus thwarting any tendency that the plate I9 might have in practice to creep.
It must now be appreciated that an improved street plate attachment for track shoes of crawler tractors has been provided which achieves the desirable objects of the invention heretofore recited.
