ROSSER MECHANISM.

Specification of Letters Patent.

Patented Sept. 14s, 1915.

Application filed January 30, 1914. Serial No. 815,421.

To all whom it may concern Be it known that 1, JOHN A. WEBER, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Rosser Mechanism; and it do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to rosser machines.

It has for its object to provide a machine which will operate a rosser and which will permit of its ready remov i from the log on which it operates.

It also has for its object to provide a rosser which is operated by machinery mounted on the ceiling beams, and which may be removed from the work by merely lifting the rosser-wheel, together with its supporting structure, to the ceiling so that it will thereby be removed from the field of action and out of the way of the saw and other mechanism. By my invention it may be used at any time and as long as desired, and then lifted to the ceiling.

A further object of the invention is to provide a means which will cause the rosser to automatically start in its rotation by placing the rosser in position for operation. A power means is also provided for lowering and lifting the rosser.

The invention has for its further object to provide a means for controlling the depth to which the rosser will cut.

()ther features will appear from the description hereinafter and from an examination of the drawings.

The invention may be contained in many constructions all of which come within the purview of my claims hereinafter appended. To show the practicability of constructions embodying my invention 1 have selectedone of such constructions as an example and describe it hereinafter. The construction selected is illustrated in the accompanying drawings, in which,

Figure 1 is a top .plan view showing the supporting structure which is fastened to the beams of the ceiling. Fig. 2 is a side view of the construction shown in Fig. 1. Fig. 3 shows a side view opposite to the view shown in Fig. 2. Fig. 4 is a section on the line y3 in Fig. 1. Fig. 5 shows a part of the clutch means for connecting the rosser with the power mechanism. Fig. 6 is a view illustrating the connecting wheels which operate the mechanism for raising and lowering the rosser. Fig. 7 is a sectional view of the connecting belt for raising and lowering the rosser, and Figs. 8 and 9 are top and end views respectively of a mechanism for bringing the controlling mechanism back to normal.

Referring to Fig. 1, l is the supporting frame which is secured to the ceiling beams 2 shown in Fig. 3. 3 is a shaft which is secured to the frame-work 1 oy means of the bracket 4. A driving pulley 5 is located on the shaft 3. The belt 6 operates the pulley 5. The rosser 7 is secured to the end of the rosser-arm 8 and is operated by a belt and pulleys l and 11. The Wheel is connected to the pulley 10 when it is longitudinally shifted along the shaft 3 by means of the clutch 13. w

The rosser arm 8 is pivoted at one end to the shaft 3 by the journals or bearing parts and 16 located in the bracket 17 to which the arm 8 is bolted. The bracket 17 is provided with a key 18 which slides in the cam 19, Figs. 1 and 41. The cam 19 operates upon the plate 20. They are each provided with two raised portions having inclined surfaces 21. Rotation of the plate 20 is prevented by the arm 22 which has a slot 23 in which the shaft 24- is positioned. When the cam 19 is turned in one direction by the movement of the arm 8 and bracket 17, it moves over the plate 20 and is pushed laterally by the inclined portions 21 which push the clutch 13 along the shaft 3 and causes frictional engagement between the wheels 5 and 10. When the arm 8 is raised the cam' .which throws out the connection between the two pulleys.

The rosser is raised and lowered by the driving power. This is accomplished by the cable which is attached by means of a staple or ring 31 to the arm 8. The cable 30 passes over the pulley 32 located in the frame 1 and also passes over the spool 33, the pulley 34 and the pulley 35. It is attached at its other end to the counter balancing weight 36. The cable may be wound around the spool33 two or three times in order to make a driving connection between the spool 33 and the cable 30. The spool 33 is operated by the sprocket-wheel 64 and the sprocket-chain 37 which is connected to the sprocket 38 located on a shaft 24 supported directly above the shaft 3. The sprocket 38 is connected to the wheel 39. The sprocket 38 and the wheel 39 are journaled on an eccentric 40. The eccentric 40 is keyed to the shaft 24. When the shaft and eccentric are turned in one position the wheel 39 is raised and when the eccentric is turned to another position the wheel 39 is lowered. The wheel 39 is driven by the wheel 41, either by means of the belt 42 which connects the two pulleys together or by frictional contact with the wheel 41 when the wheel 39 has been lowered by the operation of the eccentric 40 to bring them into contact. hen the wheel 39 is raised, the belt 42 is tightened which causes the wheel 39 to rotate in one direc tion and when the wheel 39 is lowered it frictionally engages with the wheel 41 which causes the wheel 39 to rotate in the opposite direction. The rotation of the wheel 39 causes the rotation of the sprocket-wheel 38 which in turn operates the spool 33 and pulls on the cable 30 which lifts the arm 8 or when the wheel 39 is turned in the opposite direction it lifts the balancing weight 36 by pull ingthe cable in theopposite direction and consequently it lowers the arm 8.

The position of the eccentric 40 may be altered by any suitable mechanism such as mechanism controlled by hand or by foot. I have shown mechanism controlled by foot. A pair of pedals 51 are attached to vertical rods 52 which are guided in a floor box 53. A sprocket-chain is attached at its opposite ends to the lower ends of the vertical rods 52 and operates on the sprocket 54. The sprocket 54 is connected by a shaft 56 to the sprocket-wheel 55. The sprocket 55 is keyed to the shaft 56 which is journaled in the floor boX 53 and in the floor bracket 57. A sprocket 58 is keyed to the shaft 24. The sprocket-wheel 58 is operated by a sprocketchain 59. The ends of the chain 59 are con- Tnect'ed to cables 60 which pass over pulleys arm 8 and when the other pedal 51 is pressed the sprockets 55 and 58 together with the shaft 24 are moved in the opposite direction which raises the wheel 39 and the sprockets 36 and 38 and the spool 33 to rotate and pull the cable 30 in the opposite direction and causes the rosser arm 8 to be lifted.

.1 means, shown in Figs. 8 and 9, may be used for keeping the wheel 39 in an intermediate position. This will cause the wheel 39 and the parts associated therewith to remain at rest. This is accomplished by means of weights which are adapted to operate on the shaft 24, Figs. 8 and 9. The weights 70 are supported on arms 73 pivoted to the shaft 24. Arms 71 are keyed to the shaft 24 and extend on opposite sides thereof. The arms 71 operate on lugs 72 which are located on arms 73 to which the weights 70 are secured. Limiting stops 74 are also provided for limiting the movement of the weights 70 due to gravity. The stops or ends 74 of the arms 73 extend over the beams 75 and limit in one direction the movement of the weights. \Vhen the shaft 24 rotated in one direction by the operation of one of the pedals 51 which causes the sprockets and 58 to rotate the shaft 24, one of the weights 70 is lifted by one of the arms 71 and this causes the wheel 39 to rotate and operate the sprockets 38 and 64 and causes the spool to lower the rosser arm 8. When the rosser arm is lowered sufficiently the foot is removed from the pedal 51 which has been pressed down whereupon the weight 70 will cause the return movements of the shaft 24 and the eccentric 40 to their normal positions. hen the other pedal 51 is pressed down the other weight 70 comes into play and when the rosser arm 8 has been lifted the desired distance the foot removed and the other weight arm causes the wheel 39 to return to its normal position and by operation through the sprockets 55 and 53 causes the pedal 51 which was pressed to return to its normal position. The normal position of the wheel 39 is an intermediate position between the operation of the wheel 41 by direct frictional engagement and the operation by the wheel 41 through the medium of the belt 42 which will permit the rosser arm 8 to remain in any position in which it may be placed by operation of the spool 33 which is thus controlled by the pedals 51.

A means is also provided for regulating the depth to which the rosser may cut. This accomplished by means of a gaging nose which is pivoted by means of the pin 81 to the arm 8. The rosser 7 will cut the bark of a,v log to such depth as will be permitted the nose 80' which rides ahead of the rosser on the top of the bark. The rosser 7 cuts behind the nose 80. If the nose 80 is placed close to the rosser 7 it will cut comparatively deep into the log operated upon.

If the nose 80 is well in advance of the rosser 7 it will raise the rosser 7 so that the lated by means of the position of the nose 80 relative to the rosser. It may be shifted in or out by any suitable mechanism. I have shown a rod 83 for operating the nose 80. One end of the rod 83 is connected to the nose 80 and the other end is connected to a lever 84 which is pivoted to the upper end of the arm 8. A link 85 is pivoted to the lever 84 and to a lever 86. The link 85 is also pivoted to the bracket 4. The end of the lever 86 is operated by means of a rod 87 which is pivoted to the lever 86. The other end 88 of the rod 87 is screw threaded.

A threaded Wheel 89 is supported and maintained in position by the U-shaped bracket 90 on the frame 1. It is located on the threaded end of the rod 87. When the wheel 89 is turned in one direction, the rod 87 is pushed longitudinally in one direction and when the wheel 89 is rotated in the op posite direction the rod 87 is pulled in the op osite direction. When the levers 86 and 84 are moved about their pivots or other supporting parts by the rod 87, the rod 83 is pulled or pushed in opposite directions. This operates the nose 80 and causes it to swing away from or toward the rosser 7 which lifts the rosser 7 or lowers it with respect to the log and causes it to cut shallow or deep according as the wheel 89 is rotated. The wheel 89 is rotated by means of a cord 95 which passes over a weighted pulley 96 and pulleys 97 and around the pulley 89 located between the arms of the U- shaped bracket 90 which operates the rod 87. When it is desired to reduce the depth at which the rosser is cutting, the cord 97 is pulled in one direction which rotates the wheel 89 in one direction and pushes the rod 87 to operate the nose 80 and vice versa.

A shield 100 may be secured above the rosser 7 for throwing the sawdust rearwardly. The rosser 7 cuts the bark to a sufiicient width in advance of the saw to allow free operation of the saw 103. The shield 100 throws the sawdust from the rosser 7 rearwardly toward the saw 103, but the saw moving at a rapid rate produces such a draft of air as to clean the dust and dirt on the log as the log 101 is carried along and also deflects or diverts any dust or dirt and the sawdust that is thrown up by the rosser 7 and shield 100.

The construction selected and described may be greatlv varied in the arrangements and connections of its parts and in the substitution of elements having equivalent functions without departing from the spirit of the invention which is described in the claims in the language of the elements shown.
