HEELING-MACHINE.

M. PETTEN- residing at Haverhill, in the county of Essex and vwhile the attaching or tion, and, .with

State of Massachusetts, have invented'an Improvement in vlleeling-Machines, of which the following is a specification.

This invention relate to certain iinprovements in heeling machines, and more particularly to lieeling machines o type shown and described in my Patent #1,119,763, dated Dec. 1,1914, in which one heel is pricked by awls on an awl-block, which is connected to the 4cross-head, while the top lift is being spanked onto another heel which has just been attached tothe shoe, and the awl-block 'is sustained,in operative, independentlyl of the cross-head,

nail-driving operation is being performed. Inthe machine disclosed in my said prior patent, frictional devices were employed for sustaining the awl-block during the nail driving operathis. frictional y engaging means, it has ibeen found'y that, under some conditions, the jar of the machine which occurs at the time the clown-stroke is finished, causes the awl-block to becomeldi'sengaged from its support, so that it falls until the awls strike the nail-plate slide, which, at that time, is directly therebeneath, thereby causing the awls vto'become chilled or broken.

move into engagementwith the awl block whenever the nail-plate is moved forward beyond the pricking position and which will be caused to remain in this position until the nail-plate is again retracted.v

For a more complete understanding of my invention reference is made to the accompanying drawings, in which, Y

Figure 1 is a front elevation of the crosshead of the machine parts thereof. Fig.

` Fig. 3 'is a cross-sectional view taken on the Specification of Letters Patent.

f the so that the awl-block can not possibly `become disconnected from the parts which support it, and the awls are illustrating certain 2 is a plan view thereof.

line 3-3 of Fig. 1. Fig. 4 is ay detail view of a portion of the operatingmechanism.

Inasmuch vas a `complete description of the entire machine may be found in said prior application, only thoseV parts have been shown r which necessarily coperate withI the particular invention to which thisy application relates.l

As shown in the drawing, G has theturret 7 ymounted in the head in the usual manner. yThe nail-plate; 17 is mountedl in guideways in the nail-plateholder M, and is adapted vto be` moved Vto nailingposition over vtliejack, orinto pricking position over the .heel-holder, disposed directly inthe rear thereof, (neitlierbeing shown): The fawl-carrier Q8 is slidably mounted `between th cross-head and is adaptedto belocked-,to the latterfby the locking shaft 51, which is moved` intojand out of' locking position upon rotation of the turret y In said priory patent Ifhave illustrateda safety mechanism for ,tlief. turret which prevents thelnail-plate from being'movedinto nailing vposition Aover :the jack when the turret is Yin spankingposition, `and also preveiitsithe turret from being"movedfrom nailing position into spanking positionwheii the slide is in nailing positiony Overthe jack, `This mechanism isiilustrated lin the present drawings, cally disposed rod 14: yat its lower end, and having an arm 85 secured thereto, which is arranged to be engaged and swung aside `by the nail-plate slide 17 when the llatterfis moved forwardv beyond the pricking ,position and a finger 86' is splined on'said shaft and is arranged to engageanotch in the turret yto lock the same. In the particular embodiment of my invention' shown, I employ this safety mechanism ,in performing the additional function oflockingthe 'awlcarrier in raised position during the drivingoperation of ythe cross-head.'y To accomplishthis result the rod 84C is extended upward abovel the upper end ofthecross-head, and a finger 110 is secured von saidextended upper end.,

sion 28 ywhich has-a lateral projection",Qfl

being so arranged that, in

projection 28V and comprises averti- Stmounted on the holder,v

,The v awl carrier 28 is provided with an eXten` the 'Cmsshead holder la and the,

said linger will beheld directly beneath said projection and will sustain the awl-carrier in its raised position. The relative position of said linger 110 and said arm 85 is suchl that, when the arm 85 is swung forward by the nail-plate slide, as the latter is moved forward beyond the front end of holder 14, so that the linger 86 locks the turret, the linger 110 will be swung beneath the projection 28, .so that it will lock the awl carrier in raised position, as shown in F ig. l.

To describe the operation more completely, when the cross-head moves upwardly, after the pricking operation is linished, the pin 100 therein engages the awlcarrier 28 and lifts it to its highest position, as shown in Fig. 3. The nail-plate slide is then pushed forward and swings the linger 110 beneath the projection 28, as before described. The shaft'84 will remain in this position, holding the linger 110 beneath said projection while the nailing-operation is performed, so that, when the cross head moves down to` perform the nailing operation, the awl carrier willbe sustained in its raised position during the entire nailingvoperation, and will not be permitted to fall so that the awls will strike the nailplate slide, When the nailing operation has been finished and the nail-plate is drawn back to pricking position,the spring 88 will rotate the shaft 84, and will move the finger 110 from beneath the projection 28, so that the awl carrier will no longer be locked in raised position, and, when the turret is rotated into spanking position, the locking bolt 51 will be moved into engagement with the carrier 28, so that the pricking operation will be performed on the next movement'of the cross-head.

I claim: l l. In a heeling machine of the character described, a vertically movable head, a nail plate, movable beneath said head between riving and pricking positions, a vertically movable awl carrier disposed adjacent said head, means to connect and disconnect said head and said carrier, a locking device supported independently of said head and movable between positions to lock said awl carrier'in raised position and to unlock it to permit it to move downwardly with the head, means, actuated on movement of the nail plate to driving position, to move said locking device into locking position, and means to return said locking device to unlocking position when the nail plate is moved into pricking position.

2. In a heeling machine of the character described, a vertically movable head, a nail plate, movable beneath said head between driving and pricking positions, a vertically movable awl carrier disposed adjacent said head, means to connect and disconnect said head and said carrier, a locking device supported independently of said head and movable between positions to lock said awl carrier 'in raised position and tounlock it to permit it to move downwardly with the head,
