metal acam locking pulley support comprising a pair of cars and a base extending across the same and projectinglaterally beyond, said ears with return and inwardly directed ex tensions which are integral with the ear form-. ing portions. 7 1

Another feature of the invention consists v in the provision of a laterally positioned base portion for forming an angle like Patent l lo. 711,510. 1 y x Still a further feature of the invention consists inthe formation of the ears by'a pair of return bend extensions, the inner extensions extending angularly of the ear portions and towards each other and terminating short of abuttable relation for forming a cord locking groove. 7 v

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

In the drawings Fig. 1 is a-perspective view of the simplest form of the inventionf Fig. 2 is a developed pla-nviewofthe 'sheet'metal strip forming the major portion of the in vention. Fig. 3 is a perspectiveview of a bracket base slightly modifiedform ofthe invention. Fig.

1 is a developed plan view of the sheet metal blank required for the major portionthereof. Fig. 5 is a perspective view of still a further modified form of the-invention. Fig. 6 is a developed plan view of the sheet metal blank required to produce the maj or portion thereof. Fig. 7 is a perspective view of still a further modified form of the. invention and includes all the features shown in forms of i the invention in Figs. 1, 3and 5. Fig. 8 is a developed plan View of the sheet metalblanl: required therefor.

In the drawings 10 indicates a pulley wheel H liiaving the spiralled grooves 11 thereon, the same being rotatably supported upon a pin .9. carried by a pair of ears 13 in the openings 14:, whereby the pulley is supported in spaced 1 cord carried bythe pulley. The base 15 is extended and projects laterally beyond the ears l3 and includes theanchorage receiving apertures 17. The ears 13 are connected to the base 15 bythe inwardly extending portions 18 which constitute return bendsofthebase 15, andherein the same are shown provided with apertureslfl registering with apertures 17 forbase anchorage purposes.

' That form of the invention illustrated in Figs. 3 and dis substantially the same as that shown in F' 1 and 2, except that an auxiliary 1 is provided and is of substantially the same length as themain base 115 and the groove 116 is extended as 1111122111161 the auxiliary base 121 is provided with' the anchoragereceivingopenings 123 positioned substantially transversely oft-he anchorage rece ving openings 117. The cars '113a re11'3osition'ed transversely of'hoth the main base 115 and the auxiliarybase 122,a nd-said ears are supported by saidfbase llathrough the returnbend portions 118 lying parallel 'tothe main base and transverselyo'f the auxiliary base. Theresultant construction is "fully as satisfactory for use asthe device showni'n the before mentioned patent. i

The device shown in the before mentioned patent is a casting and requires considerable metal inorder to form the angle bracket type and still more metal'to form the same in the flat striptype such shown in Figs. 1 and 2. The formation of the pu'lleysupporting member from sheetmetal permitstheun'aterial to be utilized with a minimum of waste,

for that form lot the invention shown in Figs. 1. and? can be formed lfroma single width strip and that form shown in. Figs. and +1- can beiformed fr in a strip of'mul'tiple widtlnj each 1 blank being substantially T- shaped and adjacent blanlis being inverted base and the base portion between the ears is reinforced in a way by the pin 12 supporting the catch pulley 10 so that the resulting construction is reinforced substantially the full length of the sheet metal base.

By reason of the formation of the groove 1 16 or its equivalent in the strip of sheet metal, said sheet must be of suitable thickness or, gage. Where it is desired to employ the base portion 215 by thereturn bend portion 218 including the registering apertures 219. bend portion 225 with apertures 226 regis a lighter gage material the invention may be formed as set forth in Figs. and 6. In this form of the invention the base 215 is apertured as at 217 for receiving suitable anchorage means and the ear portions 213 are apertured as at 21 and are connected to The ears, however, include a return tering with apertures 214 to receive the pin 12 supporting the pulley 10. Extending angularly of the ear return bend portion 225' and inwardly towards each other and parallel to the base port on 215 are the extenslons 227 which may have suitably tapered edges 228 to form therebetween a groove 229, the

fuli'equivalentof' groove 16. It will be apparent that very much lighter gage metal may be employed in this form of the invention than that shown in Figs. 1 to Ainclusive, since the ears are reinforced and the baseiis reinforced substantially throughout its length, that is,-no point in the base is weakenedby, milling, grooving or the like;

Figs. 7 and 8 show a modified form of the invention shown in Figs. 5 and .6, and in this and the invention shown in Figs. 5 and 7 is formed from a multiple width strip with no waste since the adjacent blanks are inverted as indicated by the dotted lines, each blank being substantially T-shaped. I

. The invention claimed is:

1. A mounting for. a pulley wheel compris ing an elongated sheet metal strip having an intermediate base forming portion, a pair of ear forming portionsintegral therewith and positionable at right angles to the base formtion including a return bend portion extending from the free end of the ear toward the base and terminating in abuttable relation therewith for reinforcing said ear, each ear return'bend portion including an angular extension lying parallel to said base portion within the pulley receiving channel formed by the ears, each extension terminating short of the otherto form a cord receiving groove therebetween. i

2. A mounting for a pulley wheel comprising an elongated sheet metal strip having an intermediate baseforlning portion, a pair of ear forming portions integral therewith and positionabl'eat right angles to the base forming portion for rotatably supporting said pulley wheel in spaced relation to the base portion, said base portion projecting laterally of and beyond the ear portions, an intermediate connecting portion constituting a return bend lyingparallel to and reinforcing said base portion and connecting eachear to the base portion, each ear portion including a return bend portion extending from the free end of the ear toward the base and terminating in abuttable relation therewith for reinforcing said ear, and an auxiliary base portion integral with the main base por tion and extending angularly thereof and angularly ofv the angularly extending ears, each ear return bend portion including an angular extension lying parallel to said base portion within the pulley-receiving channel formed by the ears,each extension terminating short of the other to form a cord-receiving groove thereb etween.

In witness whereof, I have hereunto afiixed my signature." I
