,Application ,May 1s, 1941, .serialrnussazio 1on1-lm. Y(o1. 10i-1s) Y This invention l'relates to -metal sign presses andhas for an objecttoprovidea small compact hand operated press vfor :making sheet metal signs, such as streetsigns-which must be painted approximately once a year,ithepress being .adapted to'emboss the letters of thestreet name so that the letters stand out from the surface of the sign and may be peasilypainted. v

A further object is to provide a sign press of this character which is portable so that it may be used at the location where the sign is to be replaced with a new sign.

A further object is to provide apparatus of this character which will be formed of a few strong, simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order. y I

With the above and other objects in View, th invention consists of certain novel details of construction and combinations of parts'hereinafter fully described and claimed, it being understood that various modications may be resorted to within the l scope of the appended claim without departing from the spirit or sacriiicing any of the advantages of the invention.

In the accompanying drawings forming a part Y of this specification:

Figure 1 is a top plan view of a metal sign press constructed in accordance with the invention.

Figure 2 is a longitudinal sectional View taken on the line 2-2 of Figure l. f

Figure 3 is a bottom plan View of the disk which supports the male dies.

Figure 4 is a top plan view of the resilient arms which support the femaledies.

Figure 5` is a detail cross sectional view taken on the line 5-5 of FigureS, showing one of the male dies. j

Figure 6 is a cross sectional view taken on the line 6 6 of Figure 4, showing one of the female dies.

Figure 7 is a frontelevation of the metal sign press.

Referring now to the drawings' invwhich like characters of reference designate similar parts in the various views, I6 designates a circular plate forming av base. An annular shoulder I I is formed on the top kof the base concentric with the axis of the base andV forms ananvil.

A post I2 is provided with a uniformly reduced lower portion I3 which is engaged in an axial portion I4 in the base. An arm I5 is provided at one end with an eye I6 which receives the upperrend of the-post. A piny I1 is engaged through fthe posti-and-tlfirouglrr the l*eye-to secure Y the-arm tothe post. Y

kThe post is provided at its outer end with a push rod YI8 which is sldablyrengaged in an .opening I9 formed in the fr ee end ofithe arm and v'below Hthearm iis equipped :witha presser .head 23. The upper end -gof ,thevpush rod is equipped'witha button '2| which extends above the arm I5, and a helical spring 2V is sleeved on the push rod and is housed in an opening 23 which opens through the top face of the arm. An operating handle lever 24 is equipped with a cam'head 25 which is received between hinge ears 26 formed integral with the top surface of the arm I5. The cam fis centrally pivoted be'- tween the ears by a pivot pin 2l passed through the cam and through the ears. When' the handle lever is rocked downward, the push rod is de- .pressed to lower the presser` head 20 into 'operative engagement with the work, land when the handle lever is rocked upward to released posi?A tion, the spring 22 withdraws the push rod and presser head upwardly to released position above the work.

VThevmale dies 28 kare arranged in an annular series on the top face of a resilient metal disk 29. The disk is provided with an axial opening i 3U to receive the reduced portion of the Ypost and rotatably mount the disk on the post. The disk is supported at its center upon a friction washer 3|, which is sleeved on the reduced portion-of the post andfsupports the disk with its outer portion out of contact with the annular shoulder II forming the anvil of the in Figure 2.

Acomparauvely thick washer 31 isnxed td the disk and surrounds the reduced v'portion I3 of the post. The washer carries a plurality of spring arms 33 .which extend radially outwardly therefrom. Female dies 34 are secured to the undersidesof the arms.

By Virtue of the washer 32 being fixed to thev disk 29, the disk and springV arms are adapted to be turnedas a-unit on'the post as kan axis of rotation to present complemental male and jfemale dies 28 fand 34-beneath the presser head` 20 of the push rod, as best shown in Figure 7.

The male dies 28 are secured to the disk by screws'35, as best shown in Figure 5. 'I 'he female dies are secured to the spring arms 33 by screws 36, best shown in Figure 6. The spring arms 33 are secured to the thick washer 32 by screws 31, best shown in Figure2.

The spring arms 33 function to yieldably hold base, as best shown 4outer portions of the spring the female dies out of engagement with the male Y y dies, as best shown in Figure 2.

In operation, thesheet metal sign is inserted between the spaced male and female dies and held in fixed position,.in any'preferred manner.

Then the diskand spring arms are rotated as a y Y unit to dispose desired complemntal dies on opposite sides of the sign at theA location where;l

a letterV is to be embossed.V The handle lever 24 is then loweredto rotate the cam 25 and push -Y down thepu'shrod. e During this movement of the push rod 'the Ypresser.head-.20'presses down .A the spring arm with the female die and the disk Q with-the male die until' the disk engages theanvil Il whereupon further movement of the ylever 24 forces thermale die to'indent the'metal 'female dies secured to the undersides of the out- 'er portions of the spring arms above the male "fdies of the disk, the spring arms normally holding the female dies jout of engagement with the male -diesg'the disk and spring arms and the washer being adapted to be turned as a unit,

. an arm xed to the top of the post and extendof the sign into the female die, resultingin an Y embossed letter which projects from the surfacev f of the sign and is easlyepainted.` Y

From the above description it thought that the vconstruction and operation of the invention Y will be fully understoodwithout furthergexplanation. Y Y A in What isvclaimed is:Y z A A metal sign press comprising, a base having an annularshoulder on its upper side form@ ing `an anvil, a post secured to therbase at the center of` the annular anvil, a resilient disk ,ro-

ing parallel with the base and terminating beyond the spring arms, a lever having an eccenj tric disk cam pivoted on the outer end of the 20V arm, and a springr retracted push rod slidably mounted in the arm and projecting above and below the arm to be forced by said cam to deform they spring arms and disk against the anvil 'for embossing a character on a metal sheet which may be'interposed between the male and female dies.VV y QEBER'G.
