Patented Apr. 28, 1953 UNITED STATES gram" OFFICE BIGGER FOR ENDLESS CHAIN-TYPE DI'ICHING MACHINES Claims.
This invention relates to new and useful improvements in ditch digging machines for gas lines, water lines, telephone cable and the like and the primary object of the present invention is to provide a novel and improved endless digger chain for the idler sprocket of a ditch digging machine.
Another important object of the present invention is that it provides an endless digger chain for ditch digging machines including novel and improved ground engaging elements so designed as to facilitate the same to efficiently dig into the ground surface.
A further object of the present invention is to provide ground digging members for an endless digger chain of a ditch digging machine that are quickly and readily applied to or removed from the digger chain in a convenient manner.
A still further aim of the present invention is to provide an endless ground digging chain that is simple and practical in construction, strong and reliable in use, small and compact in structure, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the deails of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a fragmentary side elevational view of a digger chain constructed in accordance with the present invention;
Figure 2 is a top plan view of Figure 1;
Figure 3 is an end view taken substantially in the direction of arrow numbered 3 in Figure 1;
Figure 4 is a perspective view of one of the ground engaging members of one group used in conjunction with the present invention; and,
Figure 5 is a perspective view of one of the ground engaging members of the second group of members used in conjunction with the present invention.
Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral It represents the endless driving chain of a ditch digging machine generally, including a plurality of opposed inner and outer link plates l2 and M which are connected by removable pins I6 and I8.
Removably secured on the pins l6 and N3 of selected links of the endless driving chain It, is a first group of spaced digging members which are designated generally by the numeral 20, one
2 of which is shown best in Figure 4 of the drawings. Each of these digging members 20 includes a substantially rectangular attaching plate 22 having apertures 24 and 26 that engage the pins !6 and I8. Rigidly secured by welding or the like to the outer longitudinal edge 28 of each attaching plate 22, is a flat substantially rectangular base plate 36 which is disposed at right angles to the attaching plate 22. The base plates 36 are provided with leading or forward longitudinal edges 32 which are spaced rearwardly from the leading or forward edges 34 of the attaching plates 22. The inner edges 36 of the base plates 36 are so disposed as to substantially align the czntral portion between the link plates [2 and Integrally formed with the base plates 30 is a plurality of forwardly extending transversely spaced ground engaging elements or substantially triangular teeth 38 having pointed extremities 16 and forwardly converging inner and outer edges 62 and 44. It should be noted, that the extremities in of the ground engaging teeth 38 are in transverse alignment with the longitudinal axis of the pins I6 onthe link plates 14 which the members 20 are applied. The rear inner corners of the members 26 are notched to provide inner edges 46 that frictionally engage the outer edges 48 of the inner link plates |2,.wh1ch are disposed rearwardly from the links on which the plates 22 are applied, to further aid in providing the base plates 22 with rigidity.
The numeral 56 represents a second group of spaced digging members generally, one of which is shown best in Figure 5 of the drawings' These members include attaching plates 52 that are alternately arranged relative to the members 20 and include spaced apertures 54 that engage the pins I6 and I B of the link plates on which the members 52 are applied. Fixedly secured to the outer edges 56 of the attaching plates 52, rearwardly from the forward edges 58 of the attaching plates 52, are the forward edges 60 of substantially rectangular base plates 62. Integrally formed with the base plates 62, is a pair of forwardly inclined substantially triangular ground engaging elements or teeth 64 having pointed extremities 65 and converging outer and inner edges 66 and 61. It should be noted, that the pointed extremities 65 of the teeth 64 extend forwardly from the forward edges 58 of the base plates 52 and terminate in transverse alignment with the longitudinal axes of the pins l6 on the link plates on which the attaching plates 52 are secured.
The rear inner corners of the attaching plates 52 are notched as at 68 to provide inwardly turned portions l0 having inner edges l2 that frictionally engages the inner links adjacent the links on which the plates 52 are applied. The inner edges 74 of the base plates 52 are spaced between and parallel to the link plates I2 and i l on which the plates 52 are attached.
In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description ac:- cordingly deemed unnecessary.
It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention. the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.
Havingdescribed the invention, what is claimed as is?
