JOHN SEVERIN HANSEN, OF MEDFORD, MASSACHUSETTS, ASSIGNOR TO O. A. MILLER TREEING MACHINE COMPANY, OF BROCKTON, MASSACHUSETTS, A CORPORATION OF MAINE.

TREEING-MACHINE.

LOSOlO.

To all 'whom it may concern:

Be it known that l, JOHN S. HANSEN, a citizen of the United States, residing at Medford, in the county of Middlesex and State of Massachusetts, have invented ceru tain Improvements in Treeing-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawing indicating like parts in the several figures.

This invention relates to machines for treeing boots and shoes, and more particularly to machines of the type shown in United States Letters Patent No. 442,034, dated Dec. 2nd, 1890, in which a pair of trees is supported on an oscillatory head and the trees are alternately brought into operative position with relation to an actuator, shown as a lever, which expands the trees to distend the shoes to the shape which they` possessed when removed from the lasts, and to stretch the shoes slightly. Any form of expansible trees may be used in this machine, but I have shown trees of the type disclosed in the patent to Tyler No. 319,356, granted June 2, 1885, which are expanded by a cam connected to a draft rod, which when drawn upwardly in the tree leg separates the heel from the fore part of the tree. A returning spring moves the rod and cam Vto restore the parts of the tree to their contracted posit-ion. lVhile on the expanded tree the shoe is usually subjected to rubbing and ironing with a heated or other instrument, to assist in bringing the shoe into its original shape, and to remove from it the wrinkles and creases that were formed during previous steps in its manufacture. The ironing operation polishes the shoe upper and gives it a better appearance than it would otherwise have. Sometimes also the shoe is treated to one or more applications of dressing or finishing material while on the tree.

One very important feature of my invention consists in providing a treeing machine with means for moving a tree to present it at a given point, as for instance in front of the workman who performs the rubbing or ironing operation or applies the dressing, or in operative position with relation to a mechanism which is to expand the tree or to perform some'operation upon the shoe car Patented June 25, 1912.

ried by the tree. In connection with this feature of my invention I have also provided means for removing a tree from such operative position after the tree has been expanded or the operation on the shoe has been completed. By reason of these improvements the manual. labor heretofore required for moving the tree to and from desired position is rendered unnecessary.

Another important feature of my invention consists in providing a machine having a plurality of trees with mechanism for moving said trees to present them successively at a given point, whereby the capacity of the machine is increased and the labor involved in its operation is reduced.

Heretofore when a machine having a plurality of trees has been employed, it has beennecessary for the workman to travel from one tree to another or to move the trees manually to bring them successively to the desired position, either of which procedures involves labor and consumes time. Means is also provided for securing a tree against lateral movement while in position to be operated upon and a further feature of this invention consistsin novel means for actuating the securing means or latch by which the tree is held in operative position.

In the embodiment of the invention herein shown the latch is actuated to release the tree by an actuator which is operated by the return stroke of the expanding lever' so that a separate operation is not required for this purpose. As shown the actuator and the latch move together until. the tree has been released and the latch and actuator also move relatively so that after the release of the tree has taken place the latch and actuator will be disengaged. lt will of course be understood that this means for operating the latch or similar part may be employed in various other connections than that herein explained and that the invention is not limited to the use of this means in the machine shown.

In connection with the means for releasing the tree to permit it to be moved aside, I have provided automatic means for moving said tree out of operative position as soon as it is released, and for bringing another tree within reach of the workman, so that he can, if desired, manually move said latter tree into position; to be secured and operated upon without leaving his position. This means is herein shown and described as used in connection and coperation with the mechanism above referred to for presenting the tree feet successively in the desired position, but its use is not, of course, limited to such a combination, as this feature of my invention may be used independently if desired.

A further important feature of my invention consists in providing a machine in which a manually controlled mechanism, which has heretofore been employed in treeing machines, shall, in additioirto its usual function, automatically move the trees to presentthem successively at the desired point. This arrangement results in effecting the additional operation by a mechanism which has been present in the prior machine, thus avoiding the necessity for another operating mechanism.

Another feature of my invention consists in providing a treeing machine which comprises a tree-carrier, an expansible tree, and an actuating mechanism for causing the expansion of said tree, with a connection between said actuating mechanism and the tree-carrier, by means of which said tree is presented automatically to the actuating mechanism for the purpose of being expanded, and is moved into a different position after it has been expanded by the actuating mechanism.

The machine is equipped with locking means for maintaining the trees in expanded condition so that the shoe may remain on the tree and set after the treeing operation has been performed and after a coat of dressing has been applied, if the shoe is dressed while on the tree. The expanded tree is moved. away from the workman and allowed to stand while another shoe is applied to another tree of the machine and while said latter tree is expanded and the treeing operations are performed on the shoe carried by it. The tree first acted upon is then returned to operative position, and I have provided automatic means for unlocking said tree so that it may be presented to the workman in collapsed condition ready to have the shoe removed from it. In certain classes of work, however, a second coat of dressing is to be applied before the shoe is removed from the tree, or some other operation is to be performed on the shoe, and at such times it is undesirable to have the tree collapsed when it is returned to operative position, because it would have to be again expanded in order to be in condition to be operated upon. I have therefore arranged the automatic unlocking means so that it can be removed or can be rendered inoperative at the will of the workman to discontinue the automatic unlocking of the trees as they are returned to operative position. This permits the tree Vto be presented repeat-edly in position to have the shoe carried thereon treated before the tree is collapsed'.

In all prior machines known to me in which the trees have been movable forth and back with relation to the position Vof the workman, instead of the workman traveling from one tree to the other, the means for holding the tree in expanded condition has been released and the tree contracted at or before the time when the tree was returned to its operative position in front of the workman, and when it was desired to apply a second coat of dressing to the shoe before removing it from the tree, the workman was obliged to expand the tree again before applying the dressing. This objection has been overcome by my invention inA which the means for unlocking the tree may be rendered inoperative when desired. I have also provided means under the control of the workman for releasing the lock and permitting the tree to be collapsed whenever desired.

In the machine herein shown two trees are employed and for the best results these trees are shaped one for right, and the other for left, shoes. In practice it occasionally happens that several shoes which are all rights or all lefts are to be operated upon in succession, as, for instance, when shoes are returned for a second treeing operation, and it is desirable then to use the proper tree, either the right or the left one, several consecutive times. I have therefore provided for rendering inoperative the mechanism for withdrawing the securing means which retain the tree against lateral movement and also for rendering inoperative the mechanism for moving` the trees forth and back to operative position when it is desired to einploy only one of the trees in treeing several shoes in succession. i

These-and other features of my invention, including certain details of construction and combinations of parts, will be eX- plained in detail in the accompanying description and pointed out in the claims.

Figure l is a side elevation of the machine with certain parts broken away. Fig. 2 is a side elevation of the lower portion of the machine with the parts in a different position from that shown in Fig. 1. Fig. 3 is a plan view of that lower portion of the machine shown in Fig. 2. Fig. et is a plan view partly in section, of the upper portion of the machine and with certain portions broken away. Fig. 5 is a view of a portion of the machine shown in Fig. l, with the parts in a different position. Fig. 6 is a side elevation of an intermediate portion of the machine, showing in inoperative position the mechanism for moving the tree laterally.

A indicates an upper table supported upon legs B. Said legs also support a lower table A. The upper table A has secured on it a bracket G in which a vertically arranged rockshaft 9 has bearings. The rockshaft 9 has secured thereto, by the clamping screw a head 19 which rests on a ball bearing E on the bracket so that the head may be t-urned freely by the rockshaft. The head is provided in this instance with two radially projecting arms or branches 11, 12, which form bearings for the trunnions cl of the shoe trees D. The arms 11 and 12 are counterparts of each other and the trees are also alike. It will therefore be necessary to describe only one tree and its relation to its supporting arm and to the operating mechanism. The construction of one of the trees D is clearly disclosed in Fig. 4, and such tree will be described with relation to its supporting arm 12,

The expansible tree herein shown comprises a front and a rear section which are moved toward and from each other, to expand and contract the tree, by a rod d, which is adapted to be drawn out to expand the tree bya suitable actuator shown as a lever Ll0, hereinafter described, and to be returnedto normal position to contract the tree by a spring CZ. The rod is guided in a loop d secured to the forepart of said tree, and is provided with shoulders ZT which serve as stops to limit the inward movement of the rod as it is returned to position to contract the tree. The trunnion d of the tree is held in the bearing of its supporting arm by means of a set screw CZ extending through the bearing into an annular groove d in the trunnion of the tree, as shown in Figs. 1 and 11. The supporting arm :is hollow, as shown in Fig. 4. The rod d" is surrounded in the hollow portion of the arm by a heavy coiled spring 15, which bears at the rear end against an adjustable collar 1(3,the position of which may be altered by the hand nut 17 and check nut 18. shown in Fig. 4i. The rod Z4 receives a follower 20 in front of the spring 15. The follower is provided with a downwardly proj ecting lug 21 which extends through a slot in the supporting arm, and is provided with a guide pin 22 which extends through suitable recesses in depending lugs 10a, 10b of the head, as seen in Figs. 1 and 4.

For the purpose of looking the tree so that it shall remain expanded after the actuating lever is retracted, duplicate mechanisms are provided, one on each of the branches 11 and 12 of the machine head 10. It will be necessary to describe only one of these mechanisms, reference being had particularly to Fig. 1. 24 indicates a latch connected to the head by the pivot pin 25 and held normally in the position shown in Fig.

'4f by a spring 27 connecting it to the similar latch on the branch 12 of the head. The latch 24 has a shoulder 26 to interlock with a cooperating shoulder 23 on the lug 21 depending from the follower' 2() of the tree. The tree is expanded by the actuator 40, which to this end engages the lug 21 and moves it until it reaches the position for the shoulders 23 and 26 to interlock, after which the tree is held by said shoulders in expanded condition until the shoulders are disen gaged. The position of the parts when the tree is locked in expanded condition is shown in Fig. 5. After the tree has been locked it is moved laterally away from the actuating lever, as will be described, and is subsequently returned to the actuating lever. For the purpose of unlocking the tree auto-matically to permit it to collapse when it is returned to operative positionk with relation to the actuating lever, the latch 2a is extended beyond the shoulder 26 and is provided with a head having the face 29 and also the faces 3() and 31, which latter are beveled as shown in Fig. 4. 33 indicates a stop or abutment on the head of the lever l-O and located in the path of the face 29 of the latch head as the tree is moved into posit-ion in front of the lever. The contact of the latch with the abutment 33 turns the latch far enough for disengaging the shoulder 26 from the shoulder of the tree lug 21. to unlock the tree and permit it tobe collapsed by its returning.` spring d before mentioned.

As hereinbefore explained, it is desirable in some classes of work to apply a second coat of dressing or to perform some other operation on the shoe before removing it from the tree, and in such instances it better to have the tree remain in expanded condition when it is returned to position to be operated upon. I have therefore mounted the stops 33 which cause the auto-matic collapse of the trees so that they can be rendered inoperative or can be removed from the machine when it not desired to use them. As herein shown the stops are posts secured by set screws 34 in recesses in the head of the lever, and if it is not desired to collapse the trees when they are returned to operative position, these stops may be adjusted below the plane of the latches or may be removed. 35, 35, indicate other stops or abutments on the head of the lever l0 by which the latches may be moved to unlock the tree when the stops are not used. The stops are in advance, that is, to the left as seen in Figs. 1, 4, and 5, of the sto-ps 33 in position to engage the bev,- eled face 30 of the latch head, and thereby rock the latch to release the lug 21 of the tree when the head of the lever et() is moved slightly to the right as seen in said figures.

The mechanisms above described for locking the tree in expanded condition and for other tree to said actuator.

unlocking the tree either automatically as the tree is moved into position to have the shoe on it removed, or at the will of the workman subsequent to its having been moved intoV such position, is shown in the drawings in connection with a mechanism for moving the trees to and from their operative positions, but I desire it tobe understood that my invention is not limited to the use of these mechanisms together, as it is clearly within the scope of the present invention to use either of these mechanisms without the other.

The roclshaft 9, to the upper end of which is secured the head l0, carrying the trees, also supports a cam plate 50 by means lofy whichthe shaft 9 is rocked to remove one tree from position in front of the actuator 40 and present the other tree in such position. The plate is provided on it-s upper face with cam surfaces 52, 52, separated by a depression 54, as shown in Figs. 1, 2 and 3. indicates a cam operating arm pivotally connected to the bell-crank lever 43 near its upper end at 62. The arm is provided at its rear end with a cam roll 64 to engage the cam surfaces 52 of the plate 50.

indicates a spring secured to the lower arm of the .bell-crank lever 43 and connected at its other end to the table at 72, as shown in Fig. 1. The arrangement is such that, when the bell-crank lever is moved from the position shown in Fig. l. to the position shown in Fig. 2, for causing the expansion of the tree, the spring 70 is put under tension and acts to return the lever 43 to normal position when permitted to do so. lVhen the lever is returned from the position shown in 2 to the normal position shown in Fig. 1, the cam operating arm 60 on the upper end of the lever is carried against one of the cam faces 52 of the cam plate on the roclrshaft and, by reason of the inclination of the cam face to the path of travel of the arm 60, as shown most clearly in Fig. 3, the cam plate is moved laterally in the direction of the arrow, Fig. 3, thus turning the rockshaft and moving the head 10 to carry the ltree last expanded away from the actuator 40 and to present the In this movement of the cam plate 50, the roller G4 on the arm 60 travels in contact with the cam surface 52 until it reaches the depression 54 which it enters, and then it rides up the wall of said depression and slides over the adjoining cam surface, as shown in dotted lines in Fig. 3, the momentum of the parts causing the completion of the movement of the rockshaft after the roll leaves the cam face and enters the depression 54.

tension of the spring 70, the arm 60 will be withdrawn from above the cam 52 and assume a position in front of said cam, ready to contact with the cam when the returning spring 70 is permitted to act and thereby turn the plate 50 and the rockshaft in the opposite direction to that in which they were before moved.

For the purpose of securing` the trees in operative position in front of the lever 40, the table A is provided with a forked bracket 90, see Figs. 1 and 4, between the

forks

92, 92, of which is pivoted at 94, a latch or lever 80. The lever is guided and braced against lateral strain by the forks of the bracket, and is provided with a notched head 82 adapted to receive a lug d10 with which each of the arms 11 and 12 of the tree-carrying head 10 is equipped. When the lug d10 is within the notch of the head of the securing lever the tree is firmly held against lateral movement during'the rubbing and ironing operations which may be performed on the shoe being treed. The securing lever 80 is held normally in position to embrace the lug d10 and secure a tree against lateral movement by a spring 84 connecting the lower arm of the lever with the table A. The securing lever is moved in opposition to the spring S4 at the proper time, to release the lug (K10 and permit the tree to be moved laterally, byv an actuator herein shown as a tripping device 100 operated by the bell-crank lever 43.

102 indicates a carrier one end of which is pivotally connected to the lever 43 at 40X, while the other end is removably suspended in a hanger 104 which depends from the table A, and through which the carrier may slide as it is moved by the lever 43, see Fig. 1. A block 106 is adjustably secured on the carrier and the tripping device 100 is pivotally connected to the block. The tripping device has a tail-piece 103 which extends downwardly and contacts with the block 106 below and back of the pivotal connection of the device thereto. The tail-piece acts as a stop to hold the tripping device normally in a horizontal plane, but permits it to be turned upwardly. The tripping device has at its free end a shoulder 1002 and the latch or securing lever 8O has a similar shoulder 8Oa located in the same horizontal plane and in the path ofthe shoulder on the tripping device as said device is moved by the lever 43.

The normal position of the tripping device 100 and its associated parts is shown in Fig. 1. l/Vhen the lever 43 is depressed to move the actuator 40 and expand a-,tree, the tripping device and the cam actuating arm 60 are moved into the position, relative to the coperating parts, which is shown in Fig. 2. When the returning spring 70 is permitted to act for moving the lever 43 back toward normal position, the shoulder 100a of the tripping device contacts with the shoulder a on the securing lever and rocks the head of said lever to the left, viewing Fig. 1, thereby releasing the lug d10.

It will be seen from Fig. Q that when the lever 43 is in its depressed position the roll 6st on the cam operating arm 60 stands back some distance from the cam surface 52. In the return movement of the lever the tripping device strikes the lever 80 and releases the tree, and thereafter' the roll 6a strikes the cam surface 52 and turns the rock-shaft to move the trees laterally and carry the next tree to be operated upon into engagement with the head 82 of the securing lever.

The tripping device and the securing lever move about different centers such that their shoulders 100a and 80a travel in "diverging paths, as indicated in Fig. 2, and the securing lever. is therefore disengaged automatically from the tripping device after it has been moved a short distance, sufficient to release the lug '10, and said lever is then v permitted to be returned to its normal position by its spring 84.- in time to receive and secure the companion tree which, it will be understood, is moving toward the securing lever at the same time that the released tree is moving away. The period of engagement of the shoulders can be varied by adjusting the block 10G on the bracket 102. 1While the tripping device 100 for actuating the latch is shown as reciprocating in a curved path and the latch is shown as swinging in a curved path, it is not essential to the invention that either of said parts move in a curved path.

66, 6G, indicate spring-pressed plungers secured to the legs B, B, and 56 indicates a lug formed on the cam plate 50 and which is arranged to engage one or the other of the spring plungers when either of the trees is in operative position in front of the actuator 40. The spring plungers serve two purposes. They act as yielding buffers to arrest the movement of the cam plate and they also exert a constant pressure on the cam plate, tending to turn lthe rockshaft to move the tree that is in operative position away from such position. The roclishaft turns very freely in its bearings and the force of the springs which actuate these plungers is sufficient so that they unaided, would carry the tree last operated upon away from the securing device 80 and cause the tree next to be operated upon to be brought within reach of the worlmian. This pressure becomes effective the instant that the locking lever S0 is moved far enough to release the lug d10, and the lug is thus moved out of alinement with the notch in the head of the locking lever before said lever is returned to locking position. The plungers (3G give the cam a movement, yieldingly enforced, prior to thel positive movement imparted to the cam by the arm 60 on the lever 43.

1 have shown the machine as provided with the spring plungers 06, one of which gives the roekshaft a movement for carrying the tree last operated upon away from the securing device 80 and bring the other tree within reach of the workman without requiring him to move, and also with the cam-operating arm 00 on the lever 43, which engages a cam surface 52, after the spring plunger has imparted to the rockshaft its initial impulse, and thereby accelerates the rockshaft enough to cause it to complete its movement for bringing the tree next to be operated upon into operative position, thereby pushing back the other plunger 6G into position to act the next time the rockshaft is to be oscillated. lhile for the best results I prefer to use these mechanisms in combination, it is to be understood that either of these mechanisms alone is useful in a treeing machine, and my invention in its broadest aspect is not limited to their use together but conten'lplates a treeing machine equipped with either mechanism without the other, as well as with both together.

It will be observed that the faces 8S, 83, of the head of the securing lever 80 are beveled. When a tree is moved into operative position the lug Zw contacts with one of the beveled faces 83 and forces the securing lever back against the pull of the spring 84e until the lug reaches the notch in the lever head after which the lever moves quickly forward to secure the tree against further movement or reverse movement. The spring plunger-s GG and the inclined faces 83 of the spring-actuated securing lever act as buffers cooperating to check the movement of the parts carried by the rockshaft and to prevent excessive jarring of the machine.

As has been suggested, it is at times desirable to employ one tree only, either the left or the right one, for expanding tivo or more shoes in succession, and at such times it is not advantageous to have the tree moved to and from position to be operated upon by the actuating lever 40. I have therefore so arranged the mechanisms for releasing the tree and for moving it aside that said mechanisms can be rendered inoperative at the will of the workman.

The carrier 102, as before stated, is pivotally connected to the lever @t3 at one end, and its other end is suspended by the hanger 10-1. The arm G0 has a portion 61 extending beneath the carrier. lhen it is desired to use a single tree `for several shoes in succession, the outer end of the carrier is detached from the hanger 104, and the carrier is allowed to drop into the position in which it is sho-wn in Fig. G, Where it rests upon the end portion G1 of the arm 60, which in turn rests on the outer portion of the cam plate 50, as shown. When the carrier is in this position the tripping device 100 is out of reach of the releasing lever 80,v and the cam operating arm 60 is tilted so that the roll 64 will not contact with the cam 52 and the rockshaft 9 is therefore not turned by the movement of the lever 43. The tree which is in operative position will then be expanded and locked in expanded condition by a forward movement of the head of the actuator 40 away from the workman,-that is, to the right as seen in the drawings,-and when the actuator is reversely moved the stop or abutment 35 will contact with the face 3l of the latch 24 to unlock the tree and permit it to be collapsed.

So far as I am aware of the state of the art, I am the first to provide a treeing machine with means for presenting a tree to the workman and for moving it away from him after his operation on it has been completed. I am also the first to provide a treeing machine having a plurality of trees with means for moving the trees to present them successively `at a given point in the machine, as for instance to the actuator which causes the expansion of the trees. These features I regard as of great importance and I desire to claim them broadly. It is further new with me to equipa machine which has a manually controlled device, with connections between said device and the trees whereby the trees will be automatically moved to present them in succession atl a given point.

The operation of the machine is as follows z-A shoe is applied to a tree when it is in the position in which the right hand tree is shown in Fig. 4, said tree'being contracted. The workman then depresscs the arm 43a .of the lever 43 until the lug 47 thereon has engaged the catch 4S. This movement of the lever 43 causes the lever 40 to engage the lug 2l and move the rod Z4 toward the right to expand the tree within the shoe. The latch 24 engages the shoulder 23 of the lug 21 when the tree has been expanded to the desired condition, and thereafter locks the tree in such expanded condition until the latch is released. The 'workman then performs the customary rubbing of the shoe to remove therefrom the wrinkles and creases. This rubbing usually produces some expansion of the shoe, and the strong spring 15, which has been somewhat compressed when the tree was expanded, exerts a constant pull upon the rod Zt and causes said tree to be further expanded to take up any slack in the shoe produced by the treeing operation. Vhen the treeing operation has been finished and, if desired, a coat of dressing has been applied, the workman with his foot touches the foot-piece 43X of the bell-crank .lever moving said lever slightly to his left as he stands in front of the machine and thereby disengages the lug 47 from the catch 48 on the frame to permit the lever 43 to be restored to normal position by the returning spring 70. The lever 43.

in returning to normal position actuates the tripping device 100 which releases the securing lever and permits the spring plungers 66 which are in engagement with the lug 56 of the cam plate to start the rockshaft and thus move the tree and carry its lug Zw away from the securing lever 80. The impulse given by the plunger 66 will turn the rockshaft far enough to bring the next tree to be operated upon within reach of the workman so that he could complete its movement manually without leaving his place. If the machine is equipped with the cam operating arm 60, however, the roll 64 thereon engages one of the cam surfaces 52 immediately after the tree has been released,

and accelerates the movement of the rockshaft so that the tree next to be operated upon is carried against the inclined face S3 of the securing lever, which it presses back until the lug d10 reaches the notch in the head of the lever, when it comes to rest. As said tree comes into position one of the plungers G6 is engaged by the lug 56 on the Vcam plate and is pressed back, said plunger acting as a buffer to check the movement of the rockshaft. If'the abutment 33 is in its operative position it is engaged by the face 29 of the latch head and the tree is automatically unlocked. If a further treeing operation is to be performed on the shoe carried by said returned tree, or a second coat of dressing is to be applied, the abutment 33 will have been rendered inoperative by adjusting it below the head of the lever 40 and will not be in position to engage the latch and the tree will therefore remain expanded Vhen the further operation is completed, if it is desired to remove the shoe from the tree, the bell-crank lever 43 will be depressed to move the actuator 40 far enough forward to bring the abutmentV 35 into contact with the beveled face 30 of the latch and turn said latch and unlock the tree so that it can be collapsed. If the shoe is not to be removed from the tree at this time'but requires to stand longer for permitting the dressing to dry or for any other reason, the lever 43 is depressed the full extent of its stroke and the actuator 40 engages the lug 2l of the tree immediat-ely after the latch has been turned by the abutment 35 so that the tree lis not collapsed to an appreciable extent andthe latch rengages the lug 2l to lock the tree again. In this manner the tree can be presented two lor more times, as may be desired, in position to have the shoe operated upon.

By the expression treeing mechanism I mean to include any mechanism for stretching' or shaping the shoe, such, for instance, as mechanism for expanding the tree for illing and shaping the shoe carried thereby; and by the expression means for operating upon the tree I mean to include any means for actuating the tree to cause it to fill, shape, or expand the shoe or to cause it to cont-ract for permitting the removal of the shoe therefrom. It it is desired to tree two or more shoes successively on one tree, the carrier 102 will be disengaged from the hanger 104 and allowed to rest on the tail G1 of the arm 60 in which position the tripping device 100 and the cam operating arm 60 will both be rendered inoperative. lith the parts in this position when the spring is allowed to return the lever 43 and actuator 40 to normal position, the abutment 35 on the actuator will engage the beveled tace 31 of the latch head 28 and unlock the tree so that it may be immediately collapsed and the shoe removed therefrom.

Having thus described my invention what I claim is:

1. A treeing machine comprising a tree arranged for movement toward and from a specified point and yieldingly acting means for moving the tree to present it at said specified point.

2. A treeing machine comprising a tree, means for operating upon the tree, and means for removing said tree from the position occupied by it while being operated upon, said latter means being adapted to be rendered operative or inoperat-ive at the will of the workman.

3. A treeing machine comprising a tree and a manually controlled treeing` mechanism, and connections between said tree and said mechanism for moving said tree into operative position.
