To all whom it may concern: Be it known that I, GEORGE A. QRTWEIN, a citizen of the United States, and a resident of Maple Falls, in the county of Whatcom and State of Washington, have invented certain new and useful Improvements in Automatic Shingle- Stamps, of which the followinI .is a specication.

My invention re ates to an improvement in means for marking shingles and consists in a stamp and mechanism for operating the same, which being attached to an ordinary shingle-packers press, will be caused to properly mark the bunches of shingles by the operations ordinarily used to work .said

press. e

It is now,cust mary to mark the finished bunches of shing es with a brush and stehcil. This requires the time of n operative.

IVith my improvement Aattached to a shingle-packers press, the shingles are properly stamped by the movements of the press mechanism required to bind the bunch of shingles, no additional movements or thought of the operator-beingrequired in order-that my stamping device may be properly operated..-v

Although it is now shingles, I have a machine in operation which accomplishes the objects of this invention as above related and for which 'I have applied for Letters Patent*l in the United States, filed March-1, 1909,-Serial No. 480,715. This machine works very well.1

Yet because of the use of a number of long; spiralV springs, some diiiicu'lty has been found in keeping these springs at the proper related tension.

The obj ect of this invention is to im rove the stamp mechanism illustrated an described in my application above referred to and is illustrated in the accompanying sheet of drawings in which similar characters refer to similar parts throughout and in which Figure 1 is an end elevation of a shinglepackers press, of well known construction, showin my stamping device attached, Fig. 2 isa ront elevation of the major portion of my gdevice with parts of the press frame to which it is attached, and Fig. 3 is an end l elevation of certain parts of my device not shown clearly in Fig. 1.

- More specifically: the shingle` packers press, illustrated in-Fig. 1 has 'a fra e principa-lly composed of posts 33 and 3a and.

l Specification of Letters Patent. Application ledApril 30, 1909. Serial No. 493,220.

custolmary to stencil 1 cross pieces-34, 21, and 36. A horizontal shaft 29 ind's bearlngs in pillow blocks '35, only one of which is partly shown in Figari, attached to lower cross-pieces 34. Rigrdly attached to this shaft is lever 26,v one endlv of which is pivoted to the lower end of comtothe lower'end of link 27," the upper end' of which isv pivoted tothe lower 'end of ten'- sion bar 24. Another similar set of bars, link and lever is situated on the other Side of the press. lever 23', rigidly attached thereto. A bunch. of shingles 31 occupies the cribof the machine, and the shingle ties 32 are lshown' in place thereon and pressed between lu' s on -theupper .end of tensi n bars 24 lan the upper ends of compressi n bars 25, in order that the bands, not shown, may be secured in place. By raising position. at 23 the bars 24 and .25 are caused vto occupy the dotted positions at 24 and 25 respectively. Then when the end gate 37 is turned down vthe completed bunch an ,be removed. TheV passing ofthe lever 23 to and from its two produces the principal mechanical movements of the press. And on these movements-the operation of my stamp depends, asl I will now explain.

.The dog 5a is rlgidly attached to sh";ft.2$) vnearits middle part, Fig. 3. Next to this dog, loose on shaft 29, is retained the piece 22.a provided with two lugs or stops 5, 5. Piece 22.a is free to revolve back and forth through an arc about .shaft 29 until one of the lugs 5 comes in contact -dog 5a. Consequently dog 5 controls the revolution -of piece 22a except for the lost motion in the arc refer-red to. 011e end: of flat spiihig 22 is rigidly attached to piece 22a. O-n the right-hand end of spring 22 rests 111-n of vertical compression bar 14. Bar 14 section and is free to move up and down in guide 30 which is rigidly vattached to cross beam 21a. Cross bea-m 21a is attachedA to cross beams 21 of the press frame. The upper end of compression bar 14 terminates in the wide fork 9, 9. The upper ends of fork 9, 9 furnish bearings for horizontal shaft 8% On shaft 8a are rigidly attached ears 12l` 12 of stamp box 1, said box ing markingcharactersY or type 2, Fig. The right-hand end of shaft 8, as show-n in Patented. Jan. 25, 1910.

is preferably flat and of rectangular crosspression bar 25 and the Yother` endis pivoted Shaft 29 is operated by hand '75 lever 23 to the dotted Y.

illustrated positions,

with the tail of ion gear 8, havinge teeth. ,Rigidly-attached to a bracket on the rear cross beam 36 is rack havingtwo teeth. This rack is so located that it may engage pinion 8 through a portion of the upward and downward 'movement of said pinion. On a crank arm attached to the distant end of stamp box 1 is horizontal slide 7. A vertical ide bar 11 is rigidly attached between il crossbeams 21 and 36. Guide 11 and slide 7 are s'olocated that when stamp box 1y is in the position illustrated in full lines in Fig. 1 the stamp is slightlyy inclined from a horizontal-position to lie against the lower sur.-

face of the right'handend of the bunch vof shingles 31.

But when stamp4 box 1, is inverted as shown in dotted outline atl, Fig. 1, it lies in a horizontal lane. Ink box containing ink pad 19 1s supported horizontallyon bracket 20a, rigidly attached to cross beam 21a, Fig. 2, in such a place that when type box 1 is in its dotted position at l', 'said type box may lie 'squarely thereon. The .type box lis centrally hung on --shaft 8a and to insure that slide 7 may have positive tendency to lie against guide 11, said ty'pc box. is over-balanced by-counterweight la. A washer of spring rubber 18 is placed on top of guide so that fork 9 may lie on .the same when type 2 makes suitable contact with ink pad -19.

The upper operative positions of my stamping apparatus are illustrated vin full lines in Fig. 1, while the -lower operative positions are shown in dotted outlines and designated by the primes of the same numerals used in the full line positions.

To operate my stamp :assume that abunch of shingles has 'been finished 'and marked, when the several parts of the press and stamp will be found in the positions illustrat-ed in full lilies in Fig. 1. Then it is desired to remove this bunch from the press in press.

order to pack another bunch. The end 37-is turned vdown to dotted position 37', the hand lever 23 is raised to its dotted position at 23 when, pressure being removed from the bunch-of shingles, it can be taken from the This movement of the hand lever, in addition to removing the pressure from the bunch of shingles, carries spring 22 to its dotted position at 22. The downward movement of-springv 22 either permits orforces the downward movement of compresion bar 14 and fork9. This also carries shaft 8 withl pinion 8 and type box 1 downward. Pinion .8-n1oves downward a suiiicient dis.-

. tance to permit vtype box 1 to be.revolved under the on rack 10 thereby bunch of shingles, when one of its teeth comes in contact lwith the upper tooth causing type box l to revolve about shaft 8 3 in a clock-wise direction, and carrying slide 7 out and away'from guide v11. This revolution continues until the further another bunch o f shingles occupies the crib of the press and it is desired -to compress the same preparatory to affxing the bands thereto, hand lever 23 must be carried from position 23 to position 23. `Because of the space between the tail of dog 5a and upper lug 5, when the several parts are in their dotted positions, there is some downward movement of lever 23 before said dog comes in lcontact with said lug. This permits of some pressure to be brought on the loose bunch of shingles before the compression'rod 1-1 begins lts upward movement. dien this movement beglns, fork 9,9 also moves upward and carries with it the several connected parts.

There is suiicient space'between the lower position of the pinions at 8 and the lower tooth of rack 1Q so that the typebox 1 may be carried upward sufficiently far above ink pad 19 to permit thel `said box .to revolvel above said pad. lVhen the pinion 8 strikes the rack -10 from below'the type box 1 is caused to revolve in a counter-clockwise direction and the slide 7 is carried. away from guide 11. t-urned through an angle than 180o to a position parallel with the lower side of the bunch of shingles under which it is located,'the pinion 8 has-passed the upper tooth 'of rack 10 and the slide 7 has come in contact with guide 11, so that revolution ceases. The upward movement of said type-box, due primarily to the downward movementof hand lever 28, continues until, when the bunch of shingles 31 is brought fully under the compression of the press, thel type 2,' freshly inked, is brought squarely and firmly in contact with said bunch of shingles by upward pressure from spring 22. This invention relates onlyA to the construction of the stamping mechanism and is not concerned with the more general combination of said mechanism and the mech'- anism of the press which I havemore articularly referred to in tion cited above.

Having thus described my invention, I claim,
