LASTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 545,052, dated August 2'7, 1895. Application tiled November 19| 1894:. Serial No. 529333- (N0 111011613 To all whom it may concern:

Be it known that I, FRANK CHASE, of Waterville, in the county of Kennebec and State of Maine, have invented a new and useful Improvement in Machines for Lasting Boots and Shoes, of which the followingisa specification, reference being had to the accompanying drawings, in Which- Figure 1 is a perspective view of my improvement disconnected from the old structure, to which it appertains. Fig. 2 is a central lengthwise section of the lasting-carriage of a lasting-machine with a part of the frame of the machine also in section, this sufticing to show the connection of my invention therewith. This view is taken at line 2 2 of Fig. 3, and is also a central sectional view of what is shown in the perspective, Fig. 1, eX- cept that in Fig. 1 the reciprocating plate to which the carriage is pivoted is shown moved slightly inwardly or away from the stop-plate, while in Fig. 2 the reciprocating plate abuts against the stop-plate. Fig. 3 is an end view of the lasting-carriage with my improvement,

the adjustable carriage-tilter block,its handle, and locking mechanism in place. Fig. 4 is a top plan view of a portion of the main frame and reciprocating plate which supports the lasting-carriage, the latter being removed for cl'earness. Fig. 5 is a front end view ofthe reciprocating plate and of a portion ofthe main frame, showing the screw for reciprocating the plate in section. This view is taken at line 5 v5 of Fig. 3, which cuts the screw and passes between the opposed surfaces of the stop-plate and main frame. Fig. 6 is a sectional view on line 6 6 of Fig. 4.

My invention relates to lasting-machines of the type illustrated in my Letters Patent No. 337 ,925, dated March 16, 1886, and is especially applicable to heel-and-toe mechanism of the type set forth in my patent, No. 364,088, dated May. 3l, 1887, although my invention may be embodied, if desired, in various other styles of machines.

It is of the utmost importance that machines for lasting boots and shoes should be of the greatest possible rapidity in operation and of simple mechanical construction in respect of those adjustments which are made by hand; and the object ot' my invention is to promote these two objects, that are ot' signal importance in the art.

My invention consists not only in an attachment for, first, tilting a lasting-carriage endwise by means of an adjustable tilter-bloc'k, which is of varying loperative dimensions, and, second, for securing the tilter-block and consequently the lasting-carriage iu adjusted position during the lasting operation, but also in certain combinations hereinafter set forth.

In the drawings, illustrating the preferred and, on the whole, the best of several contemplated'embodiments of my invention, A is so much ot' the lasting-carriage of known construction as is necessary to an understanding of my improvement, which, though capable of embodiment in many diierent kinds of. lasting-machines, yet forms an attachment for the well-known Chase lastingmachine. This carriage, whether provided with heel or toe lasting instrumentalities, has an endwise tilting movement on its cross-pin a, and it may be mentioned, incidentally, that it has a sidewise tilting 0r rocking movement on the lengthwise pin a. Carriage A is supported on a reciprocating plate A, which is mounted in suitable ways a2 in the frame A2 of the machine, as plainly shown in Fig. 1, plate A being reciprocated and moved into any desired position by screw 0.3 through block a4 in recess a5 of plate A. Block d4 is threaded for the passage of screw as, as shown in Figs. 2 and 4, in which gures plate A', on which and with which tilter-block B moves, (see Fig. 1,) is shown in contact with the plate A212 which is a stop-plate, against which plate A brings up at its extreme outward position. Plate A is formed with a concave recess 1 on its under face, this recess being coincident, when the plate is in ways d2, with the recess 2 in frame A2. The hole formed by the coincident recesses 1 and 2 forms a bearing for the shank portion 3 of screw a3, as will be plain from Fig. 5. A wheel A3 is provided for operating screw a5 to adjust plate A and carriage A endwise. These parts are old and well known.

In practice it is necessary to tilt the inner end of the 1astingcarriageA(and the lasting instrumentalities carried by it) into various positions, depending upon the contour or an- IOO gle of slope of the sole-piece of the boot or shoe to be operated upon, as will be readily understood by all skilled in the art without further explanation. To accomplish this adjustinent, I employ a carriage tilter-block B of varying operative dimensions. Adjustment of tiiter-block B moves the outer end of carriage A, and consequently the inner or 'Work end of the carriage, into a higher or to lower position, as required. Tilter-blockB is adjusted into any desired position by means of an arm or handleb attached to filter-block B, this'tilter-block being preferably of cam form, as shown, and pivoted to carriage A by the pin d. Plate A forms a suitable rest for the working surface b of the tilter-block as the plate moves with carriage A. The rest for the tilter-block should move with the lasting-carriage, in order that the tilterzo block may not be dragged overits rest when the carriage is reciprocated. It is important that the tilterbloclr should be locked in its adjusted positions during the operation of theparts carried by the lasting-carriage, and z5 I accordingly provide a graduated lockingplate B, into perforations b2 of which the spring-bolt Z13, which is mounted on arm or handle b, snaps when the handle is moved over the locking plate. Bolt b3 is formed 3o with a head B2 for convenience and is moved outwardly in its socket b4 in arm or handle Z9 against the tension of a spring b5, best mounted in shell b. Locking-plate B is preferably formed with inwardly-bent projections 227 for convenient attachment to lasting-carriage A at ha. A pull or push upon handle b moves the tilter-block, the work surface of which moves on its rest formed by plate A', and the lasting-carriage is tilted 4o as required, the locking-bolt snapping into a hole b2 in the locking-plate when the handle ceases to move, and the tilter-block, and consequently the lasting-carriage, being thereby secured in anydesired position, the springbolt b3 being released from its position in a (liplebl prior to pushing or pulling the hane It will be plain to all skilled in the art that the tilter-block may be of various shapes and 5o that my improvement may be altered in mechanical details Without departure from my invention. I have used the term of varying operative dimensions in connection with the tilter-block, deeming that expression apt for description of the essential point involved in the cam as an element of my improvement.

l. In a machine for lasting boots and shoes,l the combination of a tilting, reciprocating lasting-carriage with a tilter-block of varying operative dimensions and reciprocating with the lasting-carriage and means, substantially such as described, for adjusting the tilterblock and securing it in an adjusted position; said carriage being formed with a rest for the tilter-blocl; and adjustment of the tilter-block tilting the lasting carriage into a desired position, all substantially as and for the purpose set forth.

2. In machine for lasting boots and shoes, the combination of a tilting, reciprocating lasting-carriage with a tilter-block; and a rest therefor moving with the carriage; a handle for the tilter-block and means for securing the tilter-block in desired position; said block being of varying operative dimensions and adjustable to tilt the lasting-carriage, all substantially as and for the purpose set forth.

3. In a machine for lasting boots and shoes, the combination of a tilting, reciprocating lasting-carriage, with a cam-shaped tilterblock pivoted on the carriage; a perforated locking-plate attached to the carriage; an arm projecting from the cam-shaped tilter-block and a spring controlled locking-bolt mounted in said arm, the arm being movable over the face of the locking-plate and the spring bolt entering a perforation in the locking-plate, whereby the lastingcarriage is tilted into and secured in any desired position; substantially as and for the purpose set forth.

4. As a new article of manufacture, the herein described attachment for machines for lasting boots and shoes, said attachment co1nprising a perforated locking-plate; a tilterblock of varying operative dimensions; a handle for said block; a pivoted connection for said block, the pivoted connection being extended to form the lengthwise pin on which the 'carriage rocks sidewise, and a spring-controlled locking-bolt mounted in said handle, substantially as and for the purpose set forth.
