To all whom it may concern:
Be it known that I, ROBERT WEIR, a citi-. zen of the United States of America, and a resident of Chicago, Cook county, Illinois,
have invented a certain new anduseful Improvement in Log-Rollers, of which the fol lowing is a specification.
My invention relates to machines for trans-. ferring logs from a sawmill log-deck to the traveling carriage of a saw.
Generally stated, it is the object of my invention to provide a simplified and highlyincrease the general this figure the log shown on t spectively a side fresh log onto the carriage. of thelog-rollin machineryand the saw-carefficient machine for delivering logs to the traveling carriage usually employed for presenting the logs to a saw.
A special object is to provide an arrangement whereby a comparatively slight inchne may be employed for delivering the 10 s to the carriage so as to avoid all danger of s 00kand consequent breakage' I Another object is to provide a form of stop mechanism which will not only readily release the logs, but which after releasing a lo' cannot possioly become jammed or rendered inoperative by the pressure of the pile of logs on the deck.
It is also an object to provide certain details and features of improvement tending-to efficiency and serviceability ofa log-rolling machine of this. character. V a
To the foregoing and other useful ends my invention consists in matters hereinafter set forth and claimed.
In theaccompanying drawings, Figure 1- is a side elevation of a'log-rolling machine constructed in apcordance with the principles of my invention and showing also the saw-carriage 'whichzreceives the logs from the deck, whereon they are heldby the stop mechan ism. In this figure ato the saw-carria e and has been presented once or twice to t e saw, as will beseen from its flattened appearance. similar toFig. 1, with the exce tion that 1n e carriage of the previous figurejhas' been sawed up and disposed'of an the stop mechanism, is now being operated forthe purpose of roll a ig. '1. F1gs.-4 and 5 are reelevation and a rear elevatron of the stop-arm -shownin Figs l and 2. Fig. 6 is'a sectional view onlinefi 6 m Fig. 3. 'As thus illustrated, my. improved log-rollriage shown in log has been delivered Fig. 2 is a view ing machine .comprises an inclined log-deck A of any suitable form or construction. A
shaftB is mounted in hearings on the said log-deck' and is provided with a. air of stops 6. The said shaft is also provi ed with an Iarm 1), adapted to connect with the pitman inder. The said piston operates to norm hold the stops 1) in the position shown in Fig. 1. In this position it will be seen that the stops engage the first log onthe deck and in this way can so all of the tionary upon ism thr s provided vers or lifting-arms I and provided at their other ends with segalso involves a pair of learms d The lower ends of these arms d are provided with slots (1 adapted to receive the bolts (1 extending throv gh the lower ends of the stops b. By referring to Figs. 4 and 5 it are preferably bifurcated, so as to receive t e provided with a sleeve (1, which works has and forth in the slotd.
The sawcarriage E can be of any suitable, known, or approved oonstruction. For example, it can be arranged to travel on ways or rails e and can be head-blocks e. ed is arranged to; travel into a position m front of the log-deck, so that it ma src-f cessively receive the logs held tpo'n t e latter. In Fig. 1 the log 2, as will teotserved, has been delivered to the carriage and has been resented to the saw, as will be seen from its flattened outer side. The operation of transferrin the deck to the carriage will ii the log on the carriage has been sawed u and disposed of the carriage is then moved into a position in front of the log-deck.
f the cylinder '0, and the upward pressure thus exerted upon the piston causes the pitman b tion of. the stop mechanism in this manner .of the stop, from'the path of the log 1, but also a lifting of the levers 1).. The levers D when thus lifted provide anincline down the log from e "understood by referring to Fig. 2 and is as follows Alert Steam is now admitted below the piston in,
involves, it will be seen, not only a removal I '1 10 This pitman, as Wlll le ol served, is connected with the piston-rod of the steam-cpl"v a ly logs to remain stathe deck A. The stop mechan- D, which are pivoted at d mental-shaped and downwardly-projectingwill Le seen that the lower ends of said sto s slotted lower ends of the arms 01. In order to reduce friction, each bolt (1 is -preferably provided with the 118L811 The carriage thus construot- I to move the stops 6 and the leversD into the position shown in said Fig. 2. The operawhich the logs roll to the traveling saw-caris much less than it would be should the I gently and wit or operative positions.
I ver-arms (1'. Thus, as stated, the pressure of is possible todeliver the logs to the saw-car- -block s. In,other words, withmy improved riage. At the same time the rear segmental portions of the levers D are brought into position to engage the log 3, so as to prevent the logs remaining on the deck from following the log 1, which latter is the one to be delivered to the carriage. Thus the levers D not only successively lift and roll the logs 1 upon the saw-carriage, but also hold the re maining logs against movement until the stops b are again brought into their normal At this juncture it will be seen that the thrust or pressure of the remaining logs upon the lever D is along a line which passes throughthe axis provided by the pivotal points at. In this way the pressure of the logs remaining on the inclined deck never have any tendency whatever to lift'the levers D, thus allowing the piston and the cylinder to readily pull the levers down and interpose the stops 6 in the path of the logs. This advantage is always present, it will beseen, regardless of the size of the log, for, as stated, the arms d are segmental in shape and are radially formed relative to the axis about which the levers swing. In other words, the pressure of the logs on the deck will always be along a line passing through the axis upor which the levers swing regandless of the point at which the foremost log contacts with the curved surfaces of the lethe logs can never-tend to lift the arms D and p can never make it in any wise difficult for the piston to draw'the levers down into the position shown in Fig. 1. As another advantage of my novel form of stop it will bese'en that the upper edges of the stop I) recede or tilt toward the saw-carriage while the log is being raised by the. leversD.- In this way it riage with a very slight inclinethat is to say, the inclinev necessary for rolling the logs stops move directly downward. With this mode of operation the logs are delivered hout shock to the saw-carriage and without danger of breaking the headconstruction the stop mechanism is not only of a character to preclude all possibility of its becoming jammed or rendered inoperative by the pressure of the logs, but is also nicely adapted to successively deliver the 10 s to the saw-carriage.
ith further respect to the novel form of stop mechanism it will be seen that the stoparms cannot give way or recede from the pressure of. the logs, since any forward movement on theinpart is necessarily accompationto hold the log on the deck until the proper time for delivering it to the saw-car'- riage. V
The stops 1; are adapted, it will be observed, to have a certain amount of movementrelatively to the lifting members or le vers D. This, as shown in the drawings, is accomplished by providing separate axesfor the said stops and liftin -levers and providing swinging and prefera ly lost-motion'con- 'nections between the stops and said levers.
This construction insures a very 'efiective and efiicient operation of the lo -roller, it being easily operated and contro led and at the same time sufficiently powerful and effective to cause the logs to be delivered one at a time in the usual and well-known manner. With the construction shown''th'at is to say, with the portions (1 formed integral with the lifting-levers D it'will be seen that lost-motion connections consisting of the slots d a-nd the rollersd between the lifting-levers and the stops are desirable, as without these lostmotion connections there would not be suflicient relative movement levers and the stops.
What I claim as my invention is' 1. A log-rolling-machine comprising a deck, a saw-carriage, a shaft carrying a stop-arm, a plurality of evers having their free ends directly but loosely connected to an arm on the stop-arm shaft and adapted to lift and roll the logs from the deck to the saw-carriage.
2. A log-rolling machine comprising a deck, a saw-carria e, a shaft carrying a stop-arm, a plurality of levers pivoted at their delivery end between the stop-arm and the saw-car riage and having their free ends directly but loosely connected to an arm on the stop-arm shaft adapted to lift and roll the deck tothe saw-carriage.- A
