SIGN MECHANISM.

Application filed Januaryt18; 1923. Seriat No. 613,347.

To all whom it may concern:

Be it'known that I, Grrnnnns-Ronnms, a subject of the King of Great Britaim-a-nd a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Sign Mechanism, of whichthe following is a specification, reterencebeingfhad to the accompanying drawings.

An object of my inventionisto-provide a sign which willjdisplay incircuitsuccessive reading matter orother characters.

Another object ofmy invention istoarrange the charactersin rows andha-ve-each row travel as a unit.

Another object ot myv invention is to provide magazines arranged in rows and said rows being arranged one above. the other, each row of said magazines being adapted to accommodate a plurality of characters in each of said magazines.

Another object of my invention is to pro.- vide means for continuously automatically effecting the succession of display of each row of characters in its order.

Another object of my invention is to pro vide means for readily changing the matter to be displayed.

Other objects will be apparent; upon the reading of this specification in conjunction with the accompanying drawings, in which Fig. 1 is a cross section taken along-the line 1-1 of Fig. 5 lookingin the-direction or" the arrows;

is a similar crosssection witlnthe operative parts in reversed position to that shown in Fig. 1;

Fig. 3 is a cross section'taken alon-g the line 3-3 of Fig. 1, looking-in the direction of the arrows;

4 is a cross sectiontaken along-the line ia-a of Fig. 1 lookinginthe direction of the, arrows;

Fig. 5 is a cross sectiontakenalong the line 5-5 of 1 looking in the direction of thearrows;

Fig. 6-is a cross section cfaportion of the character raising mechanism;

Fig. 7 is a perspective View of-one-of the characters used in my machine;

Fig. 8 is a cross section showinputhe can rier raising mechanism in modifiedform; and y Figs, 9 and 10ers similar views thereof showingthesame'; in different positions of operation;

Referring now 111 -Edeta1l to. the drawings in which similarcharactersrefer to

similar thetlinks

14 and 14? which links-are connectedfat'their other end to the; sliding bar 15 adapted'to slide inthe slots 16 in thesupports 10.

Mounted on the bar 15';are-'links;17. at the opposite end ofwhich iszpivoted the baryls which-is adapted to slide-intherecesses19, 19 through connecting pins 20 *and 20 in the ends thereofl (See Fig. 5.) Thebar 18-is normally held by the spring }21 mounted on the-pin 22 inthelink 17, againstthe pin- 23 onthe same link. Integrally connected with the said-'bar-18;are carriers 24': whose most extended 1 position projects them; in the the line of travel of the bottom -bloclcin the lower row. of characters contained in the cartridges 25, rbut not farenoughtherein to interfere with the row of characters next to the-lowest row.-

In'one-form ofthe embodiment ofmy invention shown there ismounted in the supports 10 another bar 26 which isadapted to oscillate therein and which is. operated by the link 27keyed thereto at one end, the other end being in constant contact-with the cam28, said end being provided withsuitable bearing means 29 for such purpose. Mounted on the said-rod26 arethesuspension links 30,- 30 'whichsupport the bar 31. Onthis bar are-mounted pressure projections 32. The link 30,is provided with a lug 5O Whichis normally held; bythespring 33 to the pin ti t in the support 10 of the machine, (See Figs; 1, 2, 3-, 5 and 6.).

In F gs. 8, 9 and 10, I: have," shown a modified form of mechanism for pressing the elevated. block in position 1 on the platform 36. In this form l eliminatejthe,cam and link mechanism described-in the previous paragraph. Mounted. on; the sliding rod 15 iszthe-carrier 6O ,whichextendsacross the machine so as to be adapted to raise an entire row of characters, this carrier being provided with open slots 61 which are preferably located centrally of the respective blocks adapted to be raised by them. The sliding of this carrier is controlled by the link arms 62 and 63 which are hinged at 64. The arm 62 is loosely mounted on the bar 15 so as to oscillate thereon and the l'nk arm 63 is mounted on the power-shaft 11 so as to be operated thereby. The carrier 60 is made integrally with a trip which moves therewith and which is preferably located in defense of the bottom of the slot 61. In the stationary guide 66 is pivotally mounted a dog 67, one leg of which is in the line of travel of the trip 65 and the other leg of which is adapted to press a character block which has been just raised to its limit of height into place on the platform 36. A stop, which is in the form of a bar 68 passing through the various guides 66, is provided to limit the swinging of the dog 67 in both its arcuate directions.

Character blocks 85 are held in aplurality of rows in the magazines25 on the platforms 36 and 37 respectively, such blocks being arranged in any suitable order such as for instance to form reading matter which may readily be read through the open ng 38 which may be covered with a transparent plate or covering 39, if desired. It will be understood in connection with the description of the embodiment of my invention shown that there is a plurality of magazines and that the mechanism for raising character blocks which has just been described is duplicated with reference to each magazine, having connections, however, so that the operation upon the block in each magazine will be in unison with the operation on the blocks in the other magazines, all of the blocks in the bottom row of the lower chambers of the magazines being raised at the same time and all of the blocks in the upper row of the upper chambers of the magaz'nes being pushed off their comm'onplatform 36 at the same time.

, The operation of the machine is as follows. The desired wording is arranged so as to form a row of reading matter before,

the opening 39,- consisting of one character or one blank in each of the magazines 25 visible from said opening, and several rows consisting of several characters superimposed one on the other in each of said magazines, but which characters are so arranged so as to exhibit the desired reading matter when the superimposed characters thereon have been removed. Each magazine isprovided with the same number of characters as the other magazines in the machine and each stock of characters must correspond in number with those of the other magazines" in the same machine. In

the case of continuous reading matter the characters on the blocks visible from the opening 39 are first read when said blocks fall out of their position as hereinafter described and the second row of characters is then read and so on until all of the characters in the machine have performed a complete circuit of travel when the same matter will be exhibited and read in successive sections again. This operation will be continued as long as the machine is being driven.

Power is transmitted to the machine through the pulley 12 which is given a con tinuous movement. This pulley being on the common shaft 11 with the

cranks

13, 13 which in turn are linked to the rod 15 carried in the guides 16, gives such rod a reciprocating movement in saidv guides. There being mounted on said rod the linlrs 17 having the tilting carrier bar 18 at their lower ends to which is attached the carriers 2%. one for each magazine, the said carriers will be raised and lowered carrying with them in their upward movement the row of characters lying atthe back of the lower chambers of the n'iagazines, one character in each magazine being raised at the same time.

Assuming the machine to be in the position shown in Fig. 1, the carrier 24: there being shown in its lowest position. the same will be raised until it assumes the position shown in Fig. 2, carrying with it one character in each magazine, which character is supported on its lateral edges by the flange on the partition 71. This character will be held in the position shown in Fig. until the cam28 has operated on the roller 29 to oscillate forward the bar 2-6 on which is mounted the suspension links 30, 30" carrying the rod 31 on which are mounted the pressure elements 32, one for each magazine, when pressure will be imparted to said pressure elements forcing the characters just raised onto the platform 36 and at the same time moving forward the entire stack of characters thereon and thereby pushing olt' the platform 36 the characters just er:- hibited, which fall by gravity onto the plat form 37 and which on account of its inclined plane enables the characters just dropped to rest snugly against the stock of characters in the lower chambers ofthe magazines. The carriers 24 continuing in their travel then move downward as shown in Fig. 6 and are tripped upward in their downward motion by contact with the lowest characters in the lower chambers of the magazines, such tripping being permitted by the swivel mounting of the bar 18 to which the carriers are attached. As they continue down *ard in their travel they will continue their tripped position until they reach the recesses +10 when they will again assume the positioh shown in Fig. 1 by best embodiment ofmy invention.

swing thereon a11cl,1-eciprocating the same in the slot 16. In its upward movement the lowestrow oficharacter blocks in the lower chambers of the magazines; are raised until the same are positioned"slightly above the platform 36, tliejstrips 6.5 'at'the same time engaging th'e le'gs offtli'e dogs 67, WlllCll are in its line of travel, and swings said'dogs so that then; opposite legs will be forced against the character blocks, just raised putting it into their position as the lowest characters- 1n the upper chambers at the'same time pushing" the top characters in saidupper chambers ofi' the'platitorm 36L thereby efi'ecting their fa'llby gravity to the lower ch amber's;

The machine is now" in positiongtor another cycle otniovement, raisingthe row oi characters in the lowestp'osition' in the lowei cliambers oi thefm'agazin'es tothe lowest position in the upperchambers oi -themagazines, and pushing off the" platform 36 the top row of 'jch aracters thereof.
