REACTION RESI$TING DEVICE FOR USE WITH IOXVER EXCAVATORS.
Application filed October 17, 1925. Serial No. 62,985.
My invention relates to 'reactiona'csisting sistancc device to prevent this. rearward 55 devices for use with power excavators. Parmovement of the excavator. To this end I ticularly, the invention relates to a new and have shown oneform of my device attached improved blocking device to withstand the to the rear of the excavator inl igure 1.

The members t and 5 are in Figure 1, taken from the plane indicated rigidly secured to the frame 1 and intended by the line lI-II,yFigure1; V to be stationary.

In the 09 Figure t is a fragmentary vertical longh form shown, thisliloclring n'icinbcr comprises tudinal section of a power cxcawitor, showa longitudinal I-boam 7 to the adjacent ing some parts in side elevation, to which. is flanges upon one edge of which are secured attached a modified form of my reactiona pair of spaced opposed open frames coinresistance device, one of the applications of prised of anglesS strengthened by means of 85 the same being shown in dot-and -dash lines, gusset plates. 9 secured to and intermediate with a small portion of a certain I-beam of the two angle fairies-at the corner porbroken away, the scale being substantially tions thereof. 1 provide a further brace in twice as large as that used in Figure 1; and the form of a transverse angle 10 secured by Figure 5 is an elevation of the device other gusset plates 10' to the pair of angle 90 shown in Figure 4:, taken from the plane inframes intermediate the corners thereof In dicated by the line VV, Figure 4-. order that the blocking member may posi- Referring particularly to the annexed t-ively engage the soil or other foundation 4-0 drawing in the several views of which the over which the excavator is acting, I secure dilferentelcnurntsarerespectively designated to the bottom edge of the angle frames a by the same ordinals. I suggest the frame of soil enga itin foot 11. anth in the form of dea power excavator by the ordinal l, to the vice illustrated in the accompanying dawfront end of which is pivotally supported a ing, this foot 11 takes the form of a Z-shaped swinging boom 2 from which depends a scoop bar.

'ingmember out of contact with the ground 12, when it is desired to put the same out of commission and yet not remove it'from the support 5, *I attach to the lower end of the 'blockingmember a cable or series of cables 13 which pass up over pulleys 1 1 secured to the excavator frame 1.- Suspended from the free ends of the 'cables 13 are counterweights 15 which upon being manually depressedto lift the lower end of the blocking member will retain the latter in the desired upper and inactive position, plainly shown by Figure 1.
dot-and-dash lines at the right-hand end of In Figures 1 and 5' is shown a modified type of my blocking device. The modi ication consists'in different means for supporting the blocking member proper upon the excavator frame. As shown, a transverse shaft 16, preferably one of the axle shafts, is-provi ded with a pair of split collars comprising-members 17 and 18 detachably bolted together, the collars as a whole being rotatable upon theshaft16. One part of the collar, for instance, the member 18 is formed with arboss :19-providing convenient meanstowhich to bolt the I-beam 7 of the blocking member proper. Referring particularly to Figure 4, the arrangement is shown in full lines which willprevent the forward thrust of the excavator h'aine. The
- samesetof. collars serves for both operations. When it is desired to change from the front to the rear, for instance, of the rear axle 16, the collar parts 18 are separated from the collarparts 17 and the blocking nemberproper and the collars reassembled the two parts of the split collars. It is evident that by reason of the rotation of the split collars upon the shaft 16 the drag of the blocking member over the soil 12, when the excavator mechanism shifts its position, is provided for, and yet the direction of thrust is such that this loose mounting of the split collars upon the shaft 16 does not prevent the blocking member from resisting the forward thrusts in the position shown in full lines and the rearward thrusts of the machine in the position shown in dot-anddash lines, when the scoop or trencher is forced into the soil.
The construction described provides very economical and convenient mechanism foe the desired purpose; mechanism which can be utilized either for the forward or rearward thrust of the machine; and which can be readily removed when the service of the same is not desired, or readily removed and replaced when it is desired to shift the device from service against frontthrust to service against rear thrust or vice versa.
\Vhat I claim is:
A blocking member for reaction-resisting devices utilized with power excavators comprising an I-beam; a pair of opposed spaced frames rigidly secured along one ed go to said I beam, eachof said frames comprising peripheral angle members; strengthening members secured to and intermediate of said angle frames at the corner portions thereof; other strengthening members secured to said angle frames intermediate the corners thereof; and a soil-engaging foot secured to the opposite edge of said angle frame-s, said soil engaging foot being Z-shaped in cross-section and having the web of the Z secured flatwise to the said opposite edge and at right angles to the general plane of the frame members.
Signed by me this 22nd day of Sept, 1925.
