HENRY M. LOOMER, OF BEVERLY, MASSACHUSETTS, ASSIGNOR 'l'O UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION. OF
NEW JERSEY.
BURNISHING-MACHINE.
To all whom it may concern:
Be it known that I, HENRY M. LOOMER, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts,have invented certain Improvements in Burnishing-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.
This invention relates to retaining menr hers and is disclosed as embodied in a member for retaining upon its carrier an edge setting tool for burnishing the sole edges of boots and shoes. It is necessary that such tools be easily detachable from their carrier since they are profiled to suit the shape of the particular style of sole edge being treated, and have to be changed frequently, as different styles of shoes come to the edge setting machine.
The carrier and tool are ordinarily made to telescope together, with a-groove in one member, and the retaining member is mounted on the other member and engages the groove to hold the former member in position. It has been proposed to use a flat leaf spring for this purpose having a curved portion at its end to engage the groove. 'It has been found, however, that these springs soon break in use. One reason, among oth ers, contributing to this lack of durability is that there is always more or less rocking of the edge setting tool around the axis of its telescoping connectionto the carrier or spindle, due to the movement of the shoe in the hands of the operator, and the continual twisting of the spring finally resulted in its breaking. V A
It has been proposed also to form the retaining member of a Ushaped wire having a roller mounted at its middle point for en'- gagement in the groove. I This device has proved to be too expensive to manufacture and has not gone into general use. It has also been proposed to form the retaining member of a single piece of piano wire, bent in a helix at its central portion, and having its ends extending, in parallelism, to the 'at- Specification of Letters Patent.

taching screw. This has proved perfectlyably undesirable) to eliminate this rocking movement between the tool and its support, and it is a primary object of the pres ent invention'to provide a retaining member which will combine the advantages of prior constructions and provide for this relative movement, while at the same time avoiding any wearing effect which might tend to loosen the holding power of the construction. I
An important feature of the invention consists in a retaining member having a rolling bearing, the axis of rotation being parallel to the axis of relative rotation of the tool and its support. This permits the relative movement desired and avoids undue wear upon the holding groove.
Another important feature of'the invention is a springhaving a hole and a ball mounted in the hole and held by the spring in contact with the groove to be engaged. Conveniently the ball'is held between the edges of the hole and a return bend of the spring and extends through the hole to co- Preferably also operate with the groove. the hole will be elongated in the direction in which the ball tends to move as the tool is rocked, to permit the ball to roll on the edges of the hole and in the groove, thereby preventing undue wear on the groove and the ball.
These and other features of the invention including certain details of construction and combinations of parts will be explained in connection with the accompanying drawings and then pointed out in the appended claims.
Figure 1 of the drawings is a side elevation of the tool carrying head of a machine in which the invention has been embodied.
Fig. 2 illustrates the tool and carrier separated.
1 to be retained.
Fig. 3 is a section on the line 3-3 of Fig, 1, and
Fig. 4. is a rear elevational view of the novel retaining member.
The tool operating shaft 10 is oscillated in its bearing 12 in any' convenient way. It carries at its end the rotatable carrier 14 having two oppositely extending spindles 16. The carrier 14 has two operative positions, each of which brings one of the tools mounted on the spindles into the proper relation to the work. In practice a shank tool is mounted on one spindle and a forepart tool on the other. The latter is illustrated at 18, and has the'well-known groove 20 and notch 22 cooperatingwith the pin 24 011 the carrier to prevent excessive rotation about the axis of the spindle 16. The
oldleaf spring form of retaining member is shown at 26. 7
My novel retaining member is shown at 28. It consists of a leaf spring bent upon itself at 30, and having an oblong hole 32 in the rebent portion. In this hole is seated a ball 34: the diameter of which is greater than the smaller dimension of the hole. The larger dimension of the hole is transverse to the axis of the spindle, as shown inFig. 3'.
As the tool is slightly rocked on the spindle by the turning of the shoe in the hands of the operator,"the ball 3A rolls back and forth in the slot 32. Much of the torsional action on the spring is thus avoided, since the pressure exerted by the ball on thespring has a shorter lever arm than is the case with the torsional stress exerted on such a spring as 26,and breakage is therefore largely reduced. At the same time, the rolling'of the ball in the groove 20 wears it much less than the scraping action characteristic of other forms of retaining members.
The ball 34 is arranged to engage the up:- per part of the notch 20 in order to hold the tool firmly in position.
7 Having described my lnvention, what I claim as new and desire tosecure by Letters Patent of the United States is l.- A retaining member comprising a leaf spring-having a hole and a ball seated in the hole and held by thespring against the tool 2. A retaining member comprising a spring re-bent upon itself and having a hole in'one arm, and a bearing member seated in the hole and confined between the arms.
3. A retaining member comprising a spring re-bent upon itself and having a hole in the re-bent portion, and a bearing member seated in the hole and confined between the re-bent portion.
4:. A retaining member comprising a spring re-bent upon itself and having an elongated holefin one arm, and a bearing member-seated in the hole and confined between the arms of the spring.
having a groove substantially at right angles to the axis of the spindle, a resilient member mounted'in' connection with the spindle, having a hole and a ball held in the grooveby the spring.
8. In-a machine of the class described, a spindle and a socketed member arranged to receive the spindle in the socket, the member having a groove substantially at right angles to the axis of the spindle, a resilient member mounted in connection with the spindle liaving an elongated hole witli its longer di mension substantially perpendicular to the axis of the spindle, and a ball mounted in i the hole arranged to engage the groove.
9. In a machine of the class described, a spindle anda socketed member arranged to receive the spindle in the socket, the member having a groove substantially at right angles to the axis of the spindle, a re-bent member mounted in connection with the spindle 1mg, ing a hole in the re-bent portion having its longer dimension perpendicular to the axis of the spindle and a ball confined between the edges of the hole and the main arm of the spring, and extending through the hole to cooperate With the groove.
10. A retaining member comprising a spring having a hole in it, and a ball mounted. in the hole, the configuration of the spring being such as to confine the ball therein. i V a 11.- A retaining member comprising a leaf spring having-an elongated hole in it, and a ball mounted in the hole.
12.. A retaining member comprising a spring having a hole and a ball mounted in the hole, the diameter of the ball being greater than theleast crossedimension of the hole, and the spring having an extension arranged'to hold the ball in the hole.
13. In a machine of the class described,
a spindle, an edge-setting tool mounted 12 0 7 transversely to the axis of said rotative movement, and a ball mounted in the hole. 15. In a machine of the class described,
a spindle, an edge-setting tool mounted 5 thereon for rotative movement around the axis of the spindle, and a retaining memher for the tool having a roller bearing constructed and arranged to rotate around an axis parallel to the axis of the spindle to permit small relative rotations between the 10 tool and spindle.
In testimony whereof I have signed my name to this specification.
