e it known that WILLIAM G. HAGMAIER, a citizen of the United States, residing at West Allis, in the county of Milwaukeeand [State of Wisconsin, has invented a certain new and useful Improvement in Timber- Ma nipuluting lifechanism, of which the folloWIn is a specification.

This invention relates in general to 1m-r l0'p1'over nents in the construction and operation of sawmill machinery, and relates more specifically to im roved mechanism for loading and adjust'ng timber in sawmills. An object of the invention is to provide simple and eflicient timber loading, unload:

ing'andadjusting mechanism. Another 0bjee't of the invention is to provide improved mechanism which is especially adapted for losidiug and adj'u ting timber'u on sawm ll carriages. A fui'tl erobject oft e invention is to provide a combined ni ger be! nd' push arni structure for sztwmlills, which is simple and compact in construction and elficient in operation. Satil-l enother object of the invention is'to provide an in; roved timbei" ed-justing arm Which i's sxvi'ngeble about an axis and which is readily removable from its support. Another object of the invention' is'to provide a stop late for nig er bars, which may bejlocatecf near the effective partof the her and above the ush arm rockshaft which is located in pro imityto the ni er bar. These'tndothei' objects and ad van 'agesjof the present invention will be apparent from thelollowing descri tiqn A clear conce tion of an emloodl ment of the invention and of the operetion of meehanism constructed in accordance th rewith, may be had by referring mum drawing accompanying and forming a part of this specification, in Which like'reference characters desi mate the same orsimiler parts in the verious views.

A stop plate 9 located above the axis of the rock shaft and closely adjacent to the carriage 17, is provided at its forward face with a front stop plate 1 1, and at its rear face with a rear stop plate 13, these stop plates being interconnected by means of bolts 23, a reaction plate 12, and springs 11, in such a manner that the lateral movement of the nigger lHl-l 5 is cushioned in both directions. The rock shaft bearing caps 27 are located in recesses formed in the stop plates9 and coact with the extreme inner ends of the shaft sections 2, 3. The carriage 17 is movable past the push arm 4: and niggerbar 5 in a well known manner, and is adapted to support a piece of timber such as the log 19 which is normally held in position upon the carriage by means of gripping mechanism 18.

The floor of the carriage 17 is located in approximately the same horizontal plane as that of the stationary logdeck or timber supporting means from which the logs are delivered to the carriage. The axis. of the rock shaft 3 is preferably located some; distance below the log supporting surface of the deck and as near to the carriage 17 as possible, in order to permit the oscillating push arm 4 to effectively urge the logs resting upon the deck alongthe upper surface thereof.

During normal operation of the device, the push arm 4 may be oscillated about the rock shaft 2, 3 to convey logs from a suitable skidway onto the carriage 17 by admitting fluid under pressure to the actuating cylinder 6. After a piece of timber 19 has been properly positioned upon the carriage 17, the push arm 4 is swung back to the position illustrated in Figs. 1 and 2 by admitting fluid under pressure to the cylinder 6. If

it is desired to adjust the timber 19 upon the carriage 17 such adjustment may be effected either by means of the push arm 4 and other mechanism carried by the rock shaft 2, 3, or by means of the nigger bar 5 which may be manipulated to cause the teeth thereof to engage the periphery of the timber 19 and to make the desired adjustment. During such manipulation of the nigger bar 5, the bar may be swung laterally, that is fore and aft, within the bifurcation of the push arm 4, the forward and rearward movement of the bar 5 being cushioned by the springs 11 mounted upon the stop plate 9. When the timber 19 has been properly adjusted on the carriage, the nigger bar 5 and the push arm 4, may be positioned as indicated in the drawings, thereby permitting free movement of the carriage 17 past the timber adjusting mechanism.

It will be noted that by locating the nigger bar stop plate9 and the front and rear stop plates 14, 13 above the axis of the rock shaft 2 3, movement of the bar 5 is restrained in. close proximity to the effective portion of the bar 5 thus producing maximum stability of the bar 5 while in oper ation. The stop plate 9 also protects the bearin caps 27 of the rock shaft sections 2, 3, which caps are located directly adjacent to the prongs and within the bifurcation of the push arm 4. The push arm 4: may be conveniently and rapidly removed from the rock shaft sections 2, 3 by removing the clamping bolts from the holes 25 and withdrawing the arm Liaterally away from the rock shaft sections. The entire structure is compact and rugged thus adaptingthe same to the service required of such apparatus.

It should be understood that it is not desired to limit the present invention to the exact details of construction and of operation herein shown and described for various modifications within the scope of the claims may occur to persons skilled in theart.
