CONSTRUCTION FOR EXCAVATOR TRUCKS.` 1
'Application med July 27, 1925. serial No. 46,391.
The object ofmy invention is to provide a supporting frame for excavator trucks of simple, durable and inexpensive construction, which'fis light in weight and at the same time rigid and strong, More specifically it -is the object of my invention to provide an improved frame structure to be used in connection with that type of excavator trucks employing the linked tread, said frame being formed principally of structural steel having a minimum number of castings.
My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the ob'ects contemplated are attained, as hereina ter more fully set forth, pointed out in my claim, and illustrated inthe accompanying drawings, in which:
Figure 1 is a plan view of my improved frame structure. Figure 2 is a detail sectional view taken on the line 2-2 of Fi ure 1, and
'Figure 3 is an en elevation of my improved frame structure showing the manner in which it is applied to an excavator truck.
ot' the H-beams by rivets 12. lach pair of the said members 10 is secured at the end of the members 11. vAdjacent to the inner face of each of the members 1() I have provided an angle iron 13, one iange of which rests adjacent to the under surface of the members 11 andare rigidly secured thereto by means ot' rivets 14 in the manner clearly illustrated in Figure 2. Thus it will b e seen that the are rigidly secured against any lateral swinging movement.
Each of the lower fianges of each of the inembers10 is designed to receive a series of boxings 25 in which the shafts 26, are mounted. Said shafts 26 are designed to support tread rollers 27 which travel on the linked tread 28, said tread being designed to pass over sprockets 29 mounte on shafts 30, which in turn are mounted in boxmgs 31, said boxings being supported by brackets 32 secured to the end of the members 10, as clearly shown in Figure 3.
Mounted on top of the members 11 I have provided a series of I-beams 33 and 34. The I-beams 33 are located near the center and slightly spaced apart and are rigidly secured to the `members 11 by means of rivets 35 extending through the lower flanges of lsaid -I-beams and the upper flanges of' the members 11. Located centrally ab'ove the I-beams 33 is. a pivot plate 36 which is secured in position by means of rivets 37 extending through the upper flanges of the said I- beams 33. The I-beams 34 are arranged parallel with the I-beams 33 and spaced apart a distance equal' to their length, and are also rigidly secured to the upper flanges of the l members 11 by means of rivets 38. The ends of the members 33 and 34 are 'connected by means of channel irons 39 having their flanges extending outwardly. The lower 'flange of each of the said channels 39 is riveted to the upper flange of the outer ones of the beams 11 by means of rivets 40. Thus it will be seen that the members 33, 34 and 39 form a square frame, the corners of which are provided with gusset plates 41 riveted to the upper surfaces` ofthe members 34 and 39. Mounted on top of the frame thus the structure upon which it rests from being 9 twisted out of square.- This is quite an iml portant feature in frames of this type designed tobe used in connection with linked treads, due to the fact that a severe twisting tendency is imparted to the said frame when making short turns. The frame member 42 also serves as a tread for the excavator member which isu'otatively mounted thereon, and at the same time provides means for anchoring the teeth serve as traction means for causing the excavator to be rotated on said frame member 42.
Refer-rin to Figures 1 and 3 it will be seen that tie length of the members 39 is 110 45 which 105 member 42 to rest between the said treads.
Thus it will be seen, I have provided a frame struct-ure for excavator trucks of simple, durable and inexpensive construction, which 1s formed of structural steel, Iand which 1s rigid and strong and at the same time light in weight, and provides simple means whereby the boxings and the sprockets l of the linked tread may be easily and quickly attached.
vI claim as my invention:
A frame for excavator trucks comprising a pair of tread supporting members spaced apart and parallel with each other,
each of said tread supporting members comprising a pair of parallel channel irons spaced apart with Webs supported in Vertical planes, the inner face of said channels being provided with an angle iron, a seriesof H- beams mounted transversely on top of said channel, means for rigidly securing the lower flanges of said H-beams to the upper flanges of said channels and said angles, a-
series of I-beams mounted on top of said H-beams .and having their lower flanges riveted to the upper flanges of said H-beams, the ends of said I-beams being connected with channels to form a square frame located -centrally above the said H-beams, the corners of the upper surface of said I-beams and the last said channels being connected withgussetplates, an annular frame on top of said square frame, and means for securing said annular frame to said square frame.
