To 'all 'whom tmag/ concern:

Be it known that l, Flammarion Sorrwen! Hanssen, a citizen ofthe United States, and a resident of the city of New York, borough ofv Manhattan, county of New York, and State of New York, have invented a new and Improved lldounting, of whichr the fol` lowing is -a full,vclear, and exact descrip' tion. f f v My invention' relakiesto a mounting, and aims to provide certain new and' useful im? proveniente in connectionywithpa device of this character,l andv more particularly a mounting which is adapted to support a projecting machine; ,j

llt isl well appreciatedby those conversant with projecting apparatus such as yis utilized in billposter work, vthat considerable diiiculty has been experienced incident to vibratioinr "This difliculty is to be pred icated to the fact `that in projecting.y an image upon a surfaceadap'ted to receive the same, which projection must usually be con.` 'tinued for arelatively long period, that a minute amount of vibration transmitted to the projecting apparatus will result in a very perceptible movement of the image upon the surface. rfhis will result in a blurred appearance of all lines, and in the iinished work, an overlap will be noted which in Vmany instances calls for the entire work being rejected necessitating its duplication.

Thus yit is necessary that the projecting apparatus and receiving surface be held as nearly immovable with respect to cach other as possible to avoid defective work, and to reduce the cost of manufacture.

Having this in mind, l have constructed a mounting which may be disposed upon a supporting surface, which is subject to the usual amount of vibration, but which mount- 19211' seriai No; 467,231. f

connection with the drawings which latter present one practical embodiment of the same, and in which Figure '1 is a partly fragmentary side View of a mounting constructed in accordance with my. invention and` showing the same supporting a projecting apparatus and receiving surface of any desired design.

` Figure 2 ris a plan view thereof.

. Figure 3 is an end view of the same, and y .Figure i is a' sectional View taken along' the line 4.-'-4 and in the direction vof the arrows indicated in Figure 3.

it will be noted in these views, that the reference numeral 5 indicates the screen or image receiving surface of any desirable type, and the're'erence numeral' 6 the projecting apparatus .mounted upon the carriage 7, the said projectingapparatus serving to permit of the production of light rays which are thrown against the screen 5. p New with a view of providing means whichwillserveto guard againstany vibration'being transmitted from the supporting surface ydto; the apparatus comprising the elements 5 and 6, it will be noted that the support includes a pair of base members 9 resting upon the surface 8. These members have arms 10 attached to their bodies adjacent their outer ends, and these arms eX- tendnpon opposite sides of a bridge 11 of any desirable type, to the upper surface of which tracks 12 are secured mounting the carriage 7. 1

1n connection with the bridge 11 it is to `be noted'that the same may be of any de- Jsirable construction, as long as it incorporates rigid qualities preventing any sway or distortion on the part ofits body incident to movement of the carriage 7 over the rails 12, which is necessary to secure the desired degree of enlargement.

Further each of the arms 10 terminates in an inwardly bent portion' 13 overlying the base 14C of the bridge 11, and springs 15 extend between and have their ends secured respectively to the outer ends of the arms 10, and the base 1li of the bridge 11 whereby to support the latter.

Further springs 16 also extend between the bridge 11 and arms 10, butit is to be noted that these latter springs have their bodies arranged in a plane transverse to that in which the springs 15 lie thus the springs 15 serve as retaining elements to prevent` shoclrs in a vertical,l plane being transmitted from lthe base members 9 to the bridge ll, While the springs 16 guard against lateral movement of the 'bridge With respect to the supporting members.

From the Yforegoing it Will be noted that n n 'L I have provided a mounting Which vvill serve to support the entire apparatusneces; sary for enlargement Work, in such a manner that the parts or the same willbe held immovable with respectY to.l each other, although movement Will be permitted With respect to amain supporting surface incident to the fact that vibrations received by the said main supporting surface will be absorbed to a maximum extentv by the mounting, andthus failto be transmittedto the apparatus whereby to eliminate the 0bjections incidentto this difficulty, as has been noted in the preamble oflthis specification.

Obviously numerous modications of structure might readily be resorted to Without in the least departing from the spirit of my invention Which I claimas:

l. A support, including supporting meinbers, a bridge, arms secured to said sup-k porting members, a plurality of springs `secured to said arms, and having their opposite ends secured to saidbridge,y said springs being arranged transversely With respect to each other.

2. A support, including a bridge, a base forming a part of said bridge, supporting members, arms secured to said supporting members, springs extending between' and having their opposite ends secured to said arinsfand bridge respectively, certain of said springs being attached to the base of said bridge and arranged transversely With respect to the other springs.
