LEATHER-STAKING- MACHINE.

Specification of Letters Patent.

Mai. 99

Original application filed November 6, 1911, Serial No. 658,646. Divided and this application filed June 26, 1914. Serial No. 847,398.

To all whom it may concern:

Be it lmown that-I, FRANK F. SLoooMB, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Leather-Staking Machine, of which the following is a specification.

My present invention consists of a novel construction of a leather staking machine wherein the rollers which coact with the cams on the connecting rod are mounted in a novel manner in order that said rollers will at all times cooperate with the operative surface of the cam.

It further consists of a novel construction of a leather staking machine wherein novel means are provided for limiting the upward movement of the jaws in order to prevent injury to the operator.

It further consists of othernovel features of construction, all as will be hereinafter fully set forth. 7

This application is a division of'an application for Letters Patent for leather staking machine, Serial No. 658,646, filed by me on November 6, 1911.

For the purpose of illustrating my invention, I have shown in the accompanying drawings, one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentali ties of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these 1nstrumentalities as herein shown and described.

Figure 1 represents a sectional elevation of a leather staking machine embodying my invention, a portion of the same being broken away. Fig. 2 represents a front elevation of a portion of Fig. 1. Fig. 8 represents a sectional elevation of another embodiment of my invention. Fig. 4 represents a side elevation of a portion of Fig. 1, the roller and its adjuncts being omitted. Fig. 5 represents a sectional elevation of Fig. 4.

2 designates a connecting rod, a portion of the same being broken away, it being of course understood that said connecting rod may be actuated or reciprocated by means of a crank or other device (not shown). 3 designates a pin or pivot common to said connecting rod and the plates 4, the general contour of said plates being understood by reference to Fig. 1, said plates when in position forming with their adjuncts, a cross head 5 which reciprocates in suitable slides, and a detailed description of the latter is unnecessary since the same is old in the art.

Pivoted at 6 to the plates 4 is an upper jaw 7 and pivoted at 8 to the plates 4' is the journal 15 which is pivoted with respect thereto by means of bolts and nuts 16, or equivalent fastening devices.

17 designates a roller carried by the forked end of the journal 15 and secured therein by means of a bearing pin 18, said roller cooperating with the cam 19 on the connecting rod 2, as Will be apparent by reference to Fig. 1.

2O designates rods which are mounted on the pivot pin 3 and extend through a cross bar 31, carried by the bracket 10, and at their upper end they are provided with a plurality of nuts 22'having threaded engagement therewith and one of which serves as a lock nut.

23 is a washer between which and the cross bar 21 is interposed a spring 24, it being understood by reference to Fig. 5 that two of these rods 20 and their adjuncts are upward movement of the forward end of nderstood by reference toFigs. 1, 4 and5.

downward movement of the bracket 10, it is desirable in some cases to provide a stop therefor, and in Fig. 3, I have shown one type ofa construction which 'will accomplish this result. The rod 20 is provided witha shoulder or. a top 25 integral therewith or adjustable thereon, so that when the upper jaw 7 rocks on its pivot 6 the downward movement of the bracket lO'willbelimited; This limiting of the downward movementof the bracket 10, and thereby the th'e'upper jaw? which carries the rollers may also be obtained by providing astrap 26 which passes overthe jaw 7 on the opposite side of thevpivotalpin 6 thereof, and is secured to the plates 4 of the :crosshead 5 by means of fastening devices 27, as will be best The forward ends of the jaws carry staking rollers 63 and 64, and blades, 65 and 66, between which the skin is placed and operated upon. j K

57 is a spring suitably secured to the housing and havingone'end bearing against the lower. jaw 9, whereby the roller 58 will en-, gage with thecam 59v on the connecting rod 2. The roller 58 ismounted in a similar.

7 manner'to the roller 17, seen in the upper portion of Fig. 1, and a detailedv descrip tion of such .mountingis therefore unnec essary. Y

64 designates the front roller which is ad- 7 justably mounted with respect tothe upper forward part of the machine V their extreme forward position and held between the. body of the I .operatorand the breast roller 62, and the "rollers 63 and 64:, and the blades 65 and 66 are caused to move rearwardly through the medium of the connecting rod 2, andsince the hide is held stationary by the operator,

it will be apparent that the proper treat ment will be imparted thereto during the rearward movement of the rollers 68 anol 64, and theblades 65 and 66, the operator or attendant shifting the hide or skin until every portion'of the same-has been properly treated or staked. I c I Special attention is directed to certain of the novel features of my present invention. In devices of this character asfheretofore t constructed,considerabledifiiculty has arisen bearings in the position appear as sacrificing any of its advantages.

owing to the wear of the rollers 17 and 58 with respect to the cams 19 and 59, and since these-rollers are ordinarily mounted in sta- 'tionary bearings, the proper provision has not been made for causing the rollers to properly? cooperate with the cam.- Inmy presentdevice it will be seen that the roller 17 is pivotally carried by the threaded stem ll-so that the same may oscillate and accomm'odate itself to the operative face of-the cam-l9, so that the roller 17 willat-a ll times engage the operative; face of the cam-a l9 insteadof only a portion thereof.

In devices of this character as heretofore constructed, there-is a; likelihood of. the -up-' per jaw bounding upwardly, andsince the operator is bending thereover. in orderto properly manipulate the hide 61, itsomey times happens that the attachment secured to the upper j aw 7 will strilre the operator, 1

andin order to positively,preventtthis, I;

provide means for limiting the upward movement of the forward end ofr the jaw7 which maybe accomplishedbyplacinga stop on the rods20, as seenzin Fig.;3,;or

another manner in which this can be advantageously accomplished is by providingthe.

strap 26 which will limitthei upward move\ ment of the forward apparent.

end of the jaw, 7 as; is

It will now be apparent thatI have de.

vised a novel and useful constructionofa leather staking machine which embodiesthe.

features of advantageenumeratedias desirable in the statement of the invention and the above description, and while-I-have,.in

the present instance, shown. and described a preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various, particulars without departing from the spirit or scope of the. invention or Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
