Application filed June 16,1906. Serial No. 322,112.

To all whom it may concern:

Be it known that I, GEORGE W. Loeem, a citizen of the United States, and a resident of Bellingham, in the county of Whatcom and State of Washington, .have invented certain new and useful Improvements in Receiving- Trips and Conveyors, of which the following is a specification.

My invention relates to an improvement conveyers'for transmitting pieces of lumber from one machine to another during the process of manufacture and also to an improved receiving-trip by which said pieces of umber may be properly deposited on said conveyers. p I

The object of my invention is threefold: to reduce the amount of floor-space required in which to conduct the several processes of -manufacture, to diminish the number .of machines required for said processes, and to diminish the number of men required. to ca forward said work.

T e application of m invention to-the manufacture. of bevel-siding is illustrated in the accompanying two sheets of drawin s, in which similar characters refer to simiTar parts throughout the several views.-

Figures 1 and 2, taken together, re resent in plan view an arrangement of mac 'nes embodying my invention. Fig. 3 is a side elevation of Fig. 1. Fig.4 is an end elevation of Fi 2, and Fig. 5 is a side elevation of Fig. 2.

Figs. 1 and 3, A and B are portions of the rear ends of two wood-planers. Projecting lon 'tudinally from the rear of each of these p aners is a receiving-trip which-receives each finished boardas it comes from the planer and retains it until ithas passed entirel beyond the planer bed-plate, when it is a lowed to dro Beneath these trips are a number of pul eys, which move a series of belts transversely behind the planers, forming1 a lateral conveyer. On this conveyer t e boards fall from the trips and are transferred by it to a receptacle lying parallel with, to the rear, and to one side of said laners. By the side of said planers and in e with said receptacle is the resaw C, only the front part of which is shown. The boards are taken from said receptacle and fed by hand through this resaw, and the beveled pieces produced by it are then transferred laterally by hand to the trimmer tables F and G, Figs. 2 and 5. (Trimmer-table G is not shown in Fi 2.)- The trimmertables are located by t e side of the resaw and parallel with the planers referred to. Between and above said trimmer-tables are hung the trimmers D and E, Figs. 2 and 5. (Trimmer E is not shown in Fig. 2.) Located .between these trimmer-tables F and G is a longitudinal conveyer onto which the strips are thrown by hand after they are trimmed. This conveyer takes them to the gradin table 41, Figs. 2 and 5, all of which wil now be more particularly described.

Planers A and B, as illustrated, are alike. In planer A f and f are the upper and lower rear end rollers. 2' is the floor of the bedplate. m is a fixed guide on the left-hand side, and k is a removable guide on the right hand side, while Z is a removable guide fastened on top of guide m and projecting a short distance over the floor 'L. Through the way limited by said floor 11, side guides m and 7c, and top guides l the board M is driven by rollersf and f. Registering with the bottom and sides of this way is a receiving-tri composed of side guides 3 and 4, le ge 4', spreaders 9'9, with slotted holes 10 10, and supporting-hangers 7 7 7 7. Hangers 7 7 supporting side guide 4 are rigidly attached to beams overhead, which are not shown. Hangers 7 7 supporting side guide 3 arealso attached to beams overhead, which are not shown. The upper ends of these latter hangers, however, are hung on pins in said beams in line with each other and parallel to said guide, forming a hinged attachment which permits the ower end of'the's'e supports to swing when it is desiredto change the space between guides 3 and 4. The board N is'shown retained in this receivingtrip with one end still resting on. the planerfloor i. It may be noted that while the board N is in the illustrated position it is re.-

tained by the side guides 3 and 4 and. supported by the ledge 4 and planer-bed i; but since the ledge 4 only furnishes a support for one edge of the board the guide I is re uired' to prevent the board from turning in t e receiver as soon as it has passed from between the rollers.

.The receiving-trip in the rear of laner B is in all res ects similar to the one a ove described. n planer B the board 0 between the rear end rollers g and g has pushed, the board P off of the planer-bed i, and it is now entirely within the receiving-trip; but since the ledge 6 only supports the board B under one edge it falls from said trip; However, since the guides and ledge of the receivingtrip are parallel to the planer-guides and'bed the board falls from a position in a right line with that in which it moved through the planer.

The lateral conveyer beneaththe trips and behind the planers above described is composed of the horizontal shafts 18 and 19, retained in bearings 20 20 and 21 21 22 ,respectively. Bearings 20 21 are attached to beams 23 23, and'said beams are supported by suitable standards. Said bearings 20 20 and 21 21 are retained in such position that the shafts are arallel with the guides of said trip and sha t 19 preferably higher than shaft .18. On shaft 18 are the fixed pulleys 13 13 13 13, and onshaft 19 are the fixed ulleys 14 14 14 14, the pulleys 'oneach shaft being regularly spaced and paired with those on the other shaft. Belts 16 16 16 16 are carried by the several pairs of pulleys. On

' one end of shaft 19 is fastened'the driver- I this conveyer.

pulley .15, on whichruns the driver-belt 17;

his end of shaft 19 rests in bearing 22, which to the framework 25 25. At the right-hand end of this lateral conveyer is'the rece tacle 26 26 26". This receptacle .may e as shown or only a platform or merely a space at the delivery end of the conveyer, where a number of boards may accumulate. The guards a b c are fastened to the side 26 of said receptacle and prevent an accumulation of boardsin said receptacle from chafing said belts. The-conveyer-belts 16 16 16 16 are driven in the direction as'indicated by the arrows. Boards Q and R are shown on They are assumed to have dropped from the said trips. A pile of boards S, occupying a place in the receptacle 26, are assumed to have been dropped thereby said conveyer. It may be noted that said boards, Whether on said conveyer or in said receptacle, arebound to register approximately with each other at the ends nearestsaid planers.

The resaw C is in file line with planers A and B and opposite the end of receptacle 26. ()nly the front feed-rollers and a portion of the front end of this machine are shown. Board T is shown between vertical feedrollers h and h In passing throughthe resaw the finished boards are each cut into two ieces of beveled siding,-as is well understood y those familiar with these processes. From said resaw the beveled siding is transferred laterally by hand 'to trimmingtables F or G, Figs. 2 and-5. These trimmer-tables are located in file line and parallel with said planers and resaw." Trimmers D and E (partly illustrated inF-igs. 2 and 5) are sup,

ported overhead and hang over and between said trimmer-tables in file line with said laners and resaw. These trimmers are liung one in advance of the other, so that they may not collide when in operation. Trimmer D serves table F, and trimmer E serves .table'G. Table F is partly removed in order to show articles behind it. Between trimmer-tables F and G and parallel with the same is a longitudinal conveyer. This device has a conveyer-belt 30 running in the direction indicated by the arrows on pulleys 28 and 27. Pulley 28 is attached to horizontal shaft 37, which is supported by bearings 40 40, (one, of which is not shown.) These bearin s are attached to and supported on suitab e framework 44 45. Pulley 27 is fixed to horizontal shaft 38, which is supported in bearings 29 29, attached to framework 42 43. Shaft 38 is parallel with and preferably in a higher plane than shaft 37. One end of shaft 37 carries driver-pulley 29, which is driven by belt 31. Conveyer-belt 30 is sup.- ported by under board 32, to which is attached deep side guides 33 33, which are attached to standards 35 35 35, &c, vOne of said side guides ispartly removed in .Fig. 5, and a section of this conveyer is removed in Fig. 2 for lack of space. At the lower or receivin end of this longitudinal conveyer is an inc 'ned apron 34-, the lower end of which is fastened between guides 33 33 and the up per end supported on the frame of the trimmer tables. 34 is a dust-screen which prevents the trimmings from falling on the conveyer. A grading-table 41 (only partly shown) is located under the delivery end of the longitudinal conveyer; This table -is slightly inclined downward from the side nearest said conveyer. After the. strips of beveled sidin are suitably trimmed by said trimmers whi e on said trimmer-tables they are takenfrom thence and thrown by hand taken, however, to so throw them that one end may strike on said apron 34 and the other end on said belt 30. These strips are dling; but when they land in the conveyer, as described, the flexibility of the ieces causes them to bend downward, whi e the ends are supported between the said apron and said belt. destructive shock. The strip W is assumed tov have been thrown on the conve er in this manner. The friction between t e end of being carried by the belt is eater than the friction between the end of t e strip and the inclined apron 34. Hence the stri s are drawn down and forward until they '6 entirely on the belt, as illustrated'b the position of the strip X. The strip f as passing from the delivery end of the conweycr onto thegrading-table 41, where apile They are thus saved from the strip on the belt and on strips of siding is shown on said longitudinal conveyer, care being frail and can be easily split by rough hann practice I use more laners to finish the boards for delivery to t e lateral conveyerthan those herein illustrated and described. The other machines can also be increased in number or changed in kind as the needs of the several rocesses may require. The belts and other escribed appliances are well suited to the uses of a beveled-siding mill. However, for other uses to which my invention is also applicable chain or rope conveyers or some other variation of these appliances as described may be desirable. In many details also the apparatus as described can bechanged to advanta e to meet other conditions or even serve t e described conditions betteras, for instance, the ides 1 and 2 on the planer bed-plates may he replaced by rollers. Therefore I do not desire to be understood as limiting myself to the specific forms and uses herein described.

With my improved apparatus the floorspace required on which to conduct the severalprocesses necessary in finishing lumber is in the form of a rectangle measured as follows: in length by the length of the rou h material when fed into the laners, lus t e lengthof the laners, plus t -he lengtli of the pieces as they ie on the lateral conveyer, and

lus the length of the trimmed pieces as they ie on the grading-table, and in width by the distance require to properly set up and operate the file of planers, resaw-trimmers, and such other machinery asmay be required.

As com ared to the way the manufacture of bevel-siding is ordinarily carried on, my described process saves the services of one man to take the stuff from each laner. It also saves the use of one addition trimmingmachine with attendant, forin practice I use two trimmers and one single and one double planer. The longitudinal conveyer also saves the use of one or more men. In this class of work pieces of material of widelyvarying length are used. With my improved apparatus, as already referred to, these p eces are deposited by the conveyers with the ends nearest the next machine in order approximately registering, which is of great importance for the rapid and proper handling of the stufi.
