To all whom, it may concern:

Be it known that we, EDWARD L. BUCK and EDMUND G; NADEAU, citizens of the United States, residing at West Enfield, in the county of Penohscot and State of Maine,

have invented certain new and useful luv provements in Feed Attachments for Conveyers; and we do hereby declare the following to he a full, cleer, and exact description or the invention, such as will enehle others skilled in the ert to which it oppsrteins to make end use the some This invention reletes to e teed ettech ment perticulerly for e conveyer of the type c which removes logs or other objects from s hody of water in which they ere floated from the "forest for use At the present time usually et least two ere constantly employed to guide the logs to the conveyer and hold end depress them into engagement with the conveyer. This method is slow and expensive, Reelizing these conditions, it is an object of the present invention to provide en attachment "tor the conveyer which will of itself feed the logsor other objects the conveyer thus overcomin the necessity of employing the lnhor mentioned, and which will more rapidly cause engegement of the logs the conveyer more tepid conveying thereof from the Another ohject is provide :2 construction employing e feeding to engage t e logs from above and hy the weight there o to insure rapid ehective engagement the conveyer with the logs,

It is further to provide meens to pivotnlly mount the seid frame on conveyer to drive it in unison with the conveyer arrange the frame ior yielding movement to accommodate pessege oi logs thereunder and to provide guards on the frame to depend to the Water line to assist in guiding the logs or objects to the conve er.

Various additional ohjects en advantages will he pointed out and become. apparent from o consideration of the description following taken in connection with accompanying drawings illustrating an operative emloodiment.

In said drcwingsz Figure 1 is a side elevation showing the invention in use;

Figure 2 is a plan view showing the invention in use;

F' re 3 is a longitudinal vertical sec- I tiona view on the line H of Figure 2;

re 4 1s a horizontal section of the invention taken substantially on the line 4+4 of Figure 1;

Figure 5 is e cross sectional view on the line 5-5ofhi e1;

Said conveyer to ventionela The present coneis'" of e casing It3 generally rectangular, i

which an endless siorccliet chain or h lt l trevels over rollers or wheels thereof jonrceled on or shnhs t3 spanning the side Wells of said casing 135 Said chein helt let spurs or herhs 17 whic trevel in longitudme oove 1 the g Wells of the ehove seid wells so es to ch nge the logs or articles 9 and elevnte out cit Wetter. outwardly end npwerdly item the seeing 13 are guide flanges 19 he: tween which the logs pass, Seid conveyer is enchored end pieced any suitehle manner es will he readily understood. @ne other form of conveyer may he e leg helt es will he obvious. Much dittlculty is encountered in placing the logs 12 in engagement with the spurs 17, at the present time r quiring the services of two attendants constently. It is this lehor which my ettechment overcomes and which at the same time ienehles more expeditious elevation of the o s. I

eferring now to the attachment, hearings ere employed one on each side of the conveyer 10, being for instance of V shape and fastened adjacent the unconits nected ends of the legs by bolts or the like 21 to the casing 13. -A frame 10 is provided consisting of side bars 22 \connected together by means of cross rods or'ehafts 23. At one end, a rod or shaft 24 1s Tournaled in the side bars 22 and in the are keyed over which a sprocket chain 31 travels and. whereby all of the rollers 28 will be driven from-the shaft 24. ing from the side bars 22 are guide plates 32 which extend at least to the water line. These side plates 32 may be fastened in position in any suitable manner as by means of cleats 33 secured thereto and to the side bars 22. Also said side plates-32 preferably conver toward their forward ends. As a resu t of the construction described, the frame consisting of the side bars 22 and the rollers and lates 32 is free to swing upwardly from t e shaft 24 as a pivot when a log is engaged by a conveyer 14 and in its 11 ward. movement dis laces such frame.

ormally the weight 0 the frame is sufficient toprevent it being raised merely by contact of the log therewith, whereby such weight of the frame is used to insure engagement of the log with the spurs 17 Any suitable means may be used to operate the attachment.

The shaft 34 is journaled transversely of the casing 13 being driven from any suitable source such as a motor 35. On ;the shaft 34, a sprocket wheel 36 is rigidly fastened which engages the chain 14 and serves to positively drive it. Also rigid on the shaft 34'but exteriorly of the casing 13 is a pulley 37 over which a belt 38 is trained which also passes over the pulley 25. The belt 14 is driven at the same r ate of speed as the rollers 28 and from the same source of power as described.

In operation, logs or other objects 12 float- 7 ing on the water 11 will enter the attachment intermediate the side plates 32 where the same is engaged by the barbs 29 of one or more of the rollers 28, depending on Dependmesses the size of the lo. The weight of the frame be forcibly conveyed upwardly, thus overcoming the weight of the frame and causing the latter to swing upwardly to a correspondin extent on the shaft 24 as a pivot and wit the foremost shaft 23 guided by travel in the grooves 26.

A modified form is illustrated in Figures 6 and 7. In lieu of the rollers 28 an endless belt 40 is employed from which spurs or barbs 41, to function similar to those at 29, extend. Said belt 40 is carried by sprocket chains 50 which are trained over sprocket wheels 51 and 52, the former being keyed on shaft 24 and the latter keyed on a shaft 53, journaled in side bars 22 aving its end disposed for travel in the grooves 26 of the brackets 27.

- A further modified form is shown in Figure 8. It differs from Figure 6 in that a single sheet belt like 40 is supilanted by indiv dual lags or bars 54 secure to chains 50 from which the spurs or barbs 55 extend'to function like those at 29 and 41.

It will be understood that various changes in the details, combinations and arran ements of the parts ma be made provi ed they fall within the spirit and scope of the invention.

What is claimed is A feed mechanism for a conveyor comprising bearings secured to the conveyer, a shaft journaled in said bearings, a frame having sidebars pivotally mounted by said shaft, said shaft journaled in said side bars, the conveyer having a second shaft, the latter shaft extending beyond the side bars, brackets on the conveyer having grooves into which the ends of the last shaft extend, sprocket wheels on all of said shafts, a sprocket chain passing over said sprocket wheels, means to drive one of said shafts, said shafts being adapted to pass over the object to be conveyed, feed rollers on said shafts to engage the object, and depending side plates on said side bars.

In testimony whereof we aflix our signatures in presence of two witnesses.
