reference to. the drawingsit will be seen 5 that the apparatus to which the invention relatesmay be embodied in a machine having-a frame coinpcsedof posts lOIand 11 at one end and posts; 12: and 18. at the other end, which as illustrated may be made. of channel irons. These posts are connected by top longitudinal 55. rails 1e and 15 andlower longitudinal'rails 16 and 17, tcgether with end rails 18. and 19,, these parts. being suitably connected and braced asiniay berequired. The'frame also includes alateral extension which may be 60 composed of upright posts 20 and 21. and side rails 22 and 28. This extension of the frame: Y

may be placed at oneside thereof at anySuit able. or convenient. pcsition.

h Monnted in the lower party of the extension 65. 0f the. frame. there is a meter 24.. This as i1? lustrated, maybe placed on blocks 25 secured in the frame extension; A pulley 2.6 is mounted on the motor shaft 2:7 and a belt 28- passes over the pulley 2.6 and also over a pul- 70. leg .29 mounted on a. counter shaft 30 which is journaled in. suitable bearings 31, and 32 fixed in the frameof the. machine On the .cennter shaft 30 .there'is a sprocket 33. A

chain3 l. passes over this sproclfet33 and also 5 ever a. sprocket 35 mounted one shaft. 3'6;

The shaft 36 is journaled in'shitable bearings 3-7 and 38l which are also carried by the frame one end of the shaft 36 there is, a sprocket 39, the use: of which willbe hereinafter described, while. at the opposite end of this shaft 36 there is. a. gear, preferably a beveled gear 40.. This beveled gear 40 meshes with a beveled. gear 41 .mountedon a shaft- 42 1 0111% naled in the bearings 43 and 4.4, which are also. connected. to and carried by the frame of the machine. On the end of the shaft 412 opposite to that onwhich the beveled. gear 41 is connected therefis. a crank arm45. Shit-ably 'lnounted in the frame of the Ina chineand running longitudinally thereof in spaced positions there are rodsefiand 47'. On the rod 46Qthe-re is a sliding sleeve48and similarly on the rod 47. there is a sliding sleeve49. Depending from the sleeve 48 there is an arm 50' and a similar manner dependingfrom thesleeve 49' there is a corresponding arm 51. The lower ends of these arms are connected-bya rod 52. Mounted at 1 0 one end to swing on the rod 52 there is a link 53. A similar link 54 is mounted to turn at the free end of the crank 45. A connecting rod carrying threaded extensions 56 and 57 extends between and connects the links 53 and 54 m an adjustable manner whereby, as will be understood, the sleeves 48 and 49 are caused to reciprocate on the rods 46 and 47 through the action of the crank 45, the extent of the travel of the sleeves 48 and 49 depending upon the adjusted length of the connecting rod 55 which is controlled by the screw threaded extensions 56 and 57 thereof. A trip arm 58 is pivotally connected, as indicat-v ed at. 59, to the sleeve 48 and the lower end of this trip arm is normally maintained in an initial position against a stop 60 by means of a spring 61, or otherwise, which extends between the lower end of the trip arm and a pin, or other connection, for'the spring carried by the sleeve. In a similar manner a trip arm 62 is pivotally connected, as indicated at 63, to the sleeve 49. The lower end of the trip arm 62 is adapted to bear against a stop 64 when the trip arm is in its normal position and a'spring 65v is employed to normally maintain this trip arm 1n this posltlon, the spring 65 extendng from the lower end of the trp arm to a suitable pin, or other connection therefor, carried by the sleeve 49. The upper ends of these trip arms 58 and 62 extend through slots provided therefor in the upperlongitudinal rails 14 and 15 and are adapted to engage parts of an endless conveyor, as hereinafter described, in order to impart an intermittent movement thereto.

The apparatus also contemplates'the use of anrendless conveyor 66; This is preferably abelt made of canvas or other suitable material. This conveyor belt passes over a pulley 67 mounted on a shaft 68, which is journaled in suitable bearings 69 at one end of the machine, and also passes over a pulley 7 O mounted on a shaft 71, which is j ournaled in bearings 72 carried by the opposite end of the machine. The conveyor belt also passes under an idler pulley 73 journaled in bear ings 74 carried by the lower longitudinal rails, as well as under a pulley 75 carried by a shaft 76 which is journaled in bearings which are adjustable to position and also carried by the lower longitudinal rails of the machine.

The bearings in which the shaft 76 is journaled are indicated at 77 and 78. These are similarly constructed and mounted and consequently but one of them will be specifically described. As shown in Figs 6 and 7, for example, the bearing 77 is adapted to slide on a guide 79 provided therefor on the lower longitudinal rail 17 and passingthrough the bearing, 77 there is a screw threaded rod 80. The end portions of the rod 80 are mounted in brackets at 81 and 82 also carried by the lower longitudinal rail 17 whereby, as will be understood, by turning the screw threaded rod 80 the bearing 77 may be adjusted to position in order to vary the tension on the endless conveyor. Nuts 83 and 84 may be employed to lock the screw threaded rod 80 in position.

A brake device may also be employed to retard as far as may be necessary the travel of the conveyor and, as will be understood,

to also bring the same to a positive stop and. maintam 11; in position after each movement or shifting thereof. This brake device may include a lever 85 pivotally mounted as indicated at 86 on a bracket 87. At one end of the lever 85 there is a roller 88 adapted to bear against the surface of the pulley 70, whereas the opposite end of the lever 85 is connected by a spring 89 to a turn buckle 90, which in turn is connected to a bracket 91 carried by the machine frame in order to vary the tension in the spring 89 and consequently and correspondingly to vary the tension on the lever 85 and the pressure with which the roller 88 engages the surface of the pulley 70.

The endless conveyor, as hereinbefore stated, may be made of canvas, or other similar material, and is preferably so constructed as to be divided into sections. To this end we employ a plurality of bars 92 made of suitable material and extending transversely of the conveyor. Associated with each bar, as clearly shown in Fig. 8, there is a channel member 93. Each channel member 93 fits over its bar 92 with a portionof the conveyor belt intervening and these parts are secured to one another by means of screws indicated at 94, or otherwise. As indicated in Fig. 2

ice

of the drawings each cross bar 92 and its channel member 93 extends appreciably beyond the edges of the endless conveyor at both sides thereof. The cross bars 92 and their channel members 93 divide the conveyor into a plurality of sections and these may be of any desired length depending upon the distance between adjacent cross bars and their channel members. Each of these sections in the conveyor belt is adapted to receive and move a pelt, or other material, upon which a print or other impression is to be made. The projecting ends of the cross bars and their channel members 93, as well as the adjacent edge portions of the conveyor belt, travel in and between and are supported by the longitudinal rails 14 and 15 during that portion of the travel of the parts of the conveyor belt in which it is caused to move horiii:

passes around a sprocket 96 mounted on a shaft 97 which is suitably journaled in be r. 7

amaeee ings98v'earried byfthe frame of themachine. Onthe shaft Wthere is a crank99. 1 One end of a connectingrod 100. is cennected'to the crank 99 and the opposite endof' this connecting rod isi connected to a cross red I 101%- tending between and: to which thereare pivotallycennected rocker levers 102 and 103. These rocker levers are carried by a shaft 104 which is j'ournaled in bearings105-suit ably'connected to and carried by the frame of the machine, The cross rod 101 extends between the lower ends ofthe rocker levers 1102and1'03 and extending betweenthe up per ends of theserocker levers there is a cross rod 106'. Passing at right angles through this cross rod 100 andpreferably in acentrally disposed positionthere is a plunger 107. ThedownWardmovem-ent of the plunger 107 is limited bya pin 108 secured in the plunger and adapted to engage the cross bar 106 or otherwise. At its lower end the plunger 107 carries a printing head 109 7 adapted to contain a form of any desired nature for printing, or stamping, or otherwise marking the articles to bethus treated, and the plunger 107 and theprinting head 109 are yieldingly maintained in the position as shown in Fig. 1, for instance, by means of a spring 110 or otherwise. When in this position the printing head and its form are adapted to contact with an inking table 111 suitably supported on brackets 112, or otherwise.

' In order to maintain the plunger 107 in an upright or vertical position we employ a T- member connected to the cross rod 106, as illustrated in Figs. 1, 2, 3 and 4. The leg 113 of this T-member is connected to thecross bar 106 exteriorly of the rocker lever 103. The cross bar 11 1 of the T-member has corresponding ends of positioning rods 115 and 116 pivotally connected thereto. The opposite endsofthesepositioning rods 115 and 116 are pivotally connected in brackets 11'? and 118 suitably secured to the frame of the machine whereby, as willbeunderstood, the crossbar of the T -member will always be maintained in a horizontal position irres sective of the position of the rocker levers and consequently inasmuch as the plunger operates in the cross bar 106 at right angles thereto this plunger will always be maintained in an upright or vertical position.

At a suitable station the upper longitudinal rails are fitted with a base 119 extending between and secured in position therein and on this base119 there is placed a pad 120 of rubber, or other similar and equivalent yielding or resilient material. This base and pad are so placed that when the rocker levers 102 and 103 are moved to the position shown in dotted lines, Fig. 4, the printing head is adapted to contact with a pelt or other article carried by the conveyor so as to yieldingly impress the same but, as will be understood, with sufficient force to adequately transfer from that is,

. claim as-ourinvention:

per longitudinal; rails: and overlying the conveyor-belt and upon. which the pelts 122,. or 7 other articles, may be stacked, or otherwise placed 'preparatoryto transferring them to the j conveyor. These pelts are 7 manually transferred fromthe table 121to the upper horizontallytraveling portion of the conveyorfbelt in. such a. manner that a pelt is placed oneach section of the conveyor belt, between each of the transverse chan: nels 93. The parts of the apparatus, as hereinbefore described, are so geared and timed that the trip arms 58. and 62 are actuated by the movement of the sleeves 4:8. and 49 from rightto left, as viewed in Fig. 1, in order, duringthismovement of the sleeves, to engage theprojecting ends of achannel 93 and to thereby shift the conveyorbelt a predeter mined distance,depending,of course,upor11the length of the connecting rod 55,assuming the length of the crank 15 is fixed. Itwill beunderstood, of icourse, that in the movement of the sleeves 48 and 49 inthel' opposite direc tion the trip arms: 58cand 62': will be swung against the actions of the springs 61 and so as toapermit the. upperend of these trip [arms to pass under the extending ends of the next succeeding channel 93 andthat during thereturn movement of the sleeves 4:8 and 49 andthe trip. arms carried thereby the con veyor belt will remain stationary. As the conveyor belt becomes. stationary, or during the interval'inwliich: it is stationary, the printing head 109. is moved-by the rocker leverss102 and 103. to the position as shown in Fig. {has aforesaid to causethe form in the printing head to comeintoa-yielding contact withthe skin or hidesurfa'ce of la pelt with sufiicientpressure to transfer an impression from the formto the pelt. Obviously the beginning of the. return movement of the printing head by swinging the rockerlevers in the oppositedirection is started beforethe next succeeding shiftin the conveyor belt is effected. 1 It will furthermore be understood purposes without departing the nature and spirit .offthe invention.
