FRAME FOR LOG-LOADERS.

Specification of Letters Patent.

Patented June 25, 1907.

To all whom, it may concern.-

Be it known that I, JOHN R. MCGIFFERT, a citizen of the United States, resident of Duluth, county of St. Louis, State of Minnesota, have invented a new and useful Improvement in Frames for Log-Loaders, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle so as to distinguish 1t from other inventions.

My invention relates to frames for logloaders and particularly to frames adapted for use in connection with a type of logloader shown and described in Patent No. 621,043 issued to George W. Decker, March 14, 1899.

The object of the invention is to produce a construction which will be economical and efficient.

The said invention consists of means hereinafter fully described and particularly set forth in the claims.

The annexed drawings and the following description set forth in detail certain means embodying the invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings z--Figure 1 represents a side elevation of a log-loader frame embodying my invention showing the same mounted u on trucks and also showing a portion of t e hoisting and loading mechanism. Fig. 2 represents an end elevation of same. Fig. 3 represents, upon a reduced scale, a side elevation of a loader complete and embodying my improved frame.

The two lower longitudinal sills A of the said improved frame have their respective ends joined transversely by bolsters B, B, each of which consists preferably, of three I-beams, as shown in Fig. 1. From the four corners of the lower rectangular frame so formed extend four u right posts C, C each consisting of two I- cams, such osts being directly supported by the bo sters and suitably secured thereto. Connecting the front and rear posts and secured upon the inner surfaces of the latter are two parallel channel bars D forming upper sills.

Having their ends resting upon the bars D and extending between the front and rear posts respectively are two transverse members E each consisting preferably, as shown,

of two I-beams. of these members E are two longitudinal I-beams F, F disposed u on opposite sides of the vertical central ongitudinal plane ofthe machine and at equal distances therefrom, as shown in Fig. 2. Secured to the middle and outer surface of each sill A is an upright post C consisting preferably of two channel bars suitably tied together, the upper ends of these posts being secured to the outer surfaces of the longitudinal upper sills'D. Extending between these posts 1s a transverse I-beam E having its ends secured to the inner surfacesof the posts C. This I-beam E has its lower surface secured to the upper surfaces of the longitudinal beams F, F. These beams F, F form the deck for the hoisting and conveying mechanism which is carried thereby, as shown in Fig. 2. Further rigidity is secured by brac- Secured to the bottom4 ing the frame against transverse strains by means of bars Z) l) and e e as shown in Fig. 2 while longer diagonally disposed bars d, joining the outer ends of the upper sills D with approximately the center of lower sills A, serve to sustain the latter under the weight of a car as it passes through the frame on track G.

By virtue of the above-described disposition of beams F, the hoisting and conveying mechanism is carried upon a plane lower than that provided in any frame heretofore constructed, thus lowering the center of gravity of the entire structure which is an obviously desirable feature. Such lowering is eHected while still preserving the necessary height between the upper and lower portions of the structure so as to allow a car when drawn up upon the auxiliary track G to propl which is fully described and set forth in the said above-named patent. The two beams F, F being placed upon opposite sides of the central plane before mentioned, it will be seen that the projecting draw bar of the car will pass into the space included between said two beams. The height of the lower surface of beam E above the track G, G of the frame, Fig. 2, is made just sufficient to allow this draw bar to pass beneath same when the end of the car is passingup the inclined portion of the track and about to enter the frame.

As described in said patent the loading machine is provided with mechanism for selfpropulsion consisting of suitable connection IOO IIO

BEST CPY with the hoisting engine in the form of chains sprockets,fgshafts etdgjInithe constructions heretoforejutilizedjjthe drivingjjshaft for propelling theglddevicelhasijof' necessity been caused to project beyond the verticalljplane coinciding withujjloneyf extremegjside 'ofjthe frame7 and a sprocket-wheelhasbeen attached thereto Q;Injadsimilar mannerdaucountershaft and sprocket-wheel hasjbeen secured in such projecting mannerhto the lower portion of the frame; so that when the machine was passing through an obstructive country the said sprockets and chains were constantly in danger of becoming damaged or the chain torn from its sprockets by reason of contact with obstructions. It will be noted however, that in my above described construction the driving shaft II, sprocket-wheel H and sprocket chain 71, (shown in dotted lines) as well as the countershaft h and sprocketwheel h2 secured thereto may lie as shown, beyond the longitudinal sills A and D and yetnot lie beyond the lateral vertical plane of the frame7 the upright corner posts C, C forming a guard for protecting these parts, as gill be readily seen from the inspection of Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the means herein disclosed, provided the means stated by any one of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention l. In a frame for a log-loader, the combination with a base, of a deck comprising transverse beams supported above said base, and longitudinal beams lying beneath said transverse beams and secured to the same.

2. In a frame for a log-loader, the combination with a base, of posts mounted on each side thereof; a longitudinal beam secured to the posts along each side respectively of said base; transverse beams secured to opposite posts respectively; and intermediate longitudinal beams lying beneath said transverse beams and secured to the same.
