FASTENING :oEvIoE.

Application filed February 28, 1921. Serial No. 448,028.

To all whom it may concern I Be it known that I, GUsTAvE E. FRAN- Urs'r, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Fas-. tening Devices; and I do hereby declare the following to be a full, clear, and exact des'cri tion of the same reference bein 'had' to the accompanying drawings, forming a part of this specification, and-to the reference numerals marked thereon.

This invention has to do with fastening devices and relates moreparticularly to such as are adapted for fastening a closure, such,

for example, as the motor hood of an automobile, one object of the invention being 'topro vide a practical and convenientde:

vice of the above character having a single handle which serves not only for movement of the closure to and from closed position but also operates the fastening device, facilitating quick and convenient adjust ment of the closure. Another object is to provide a device of the above character located inside the closure with the parts so constructed andarranged as to holdv the latter securely against the body, together with means for automati-' cally guiding the fastening device to and from engagedposition. A further object is to provide in combination with the above an additional lock controlled fastening means preventing unauthorized opening of the hood.- To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end 'of the specification.

In the drawings: a r Figure 1 is an external side elevation'of a fastening device embodying the present invention.

Figures '2 and 3' are sectional elevations on the line 2 -2 of Figure 1 showing the parts in different positions.

Figure 4 isa sectional detail view on line l -4* of Figure 2. p

Figure 5 is a similar view on the line a of Figure 1'.

Figure 6 is a similar view on the line (St-45 of Figure 1.- I i Similar reference characters throughout the several views indicate the same parts.

The present embodiment of the invention which the bolts 13 pass.

showsfhe adaptation of the same to the purpose of fastening an automobile hood to the body, but the invention is applicable, of course, to other uses, this embodiment being intended merely by way of illustration of the principles involved and a preferred practical application thereof. At 10 is indicated one of the longitudinal beams or other part of the automobile body, while 11 indicates a closure or motor hood portion, in the pres ent instance of the type commonly pivotally supportedat one or more points 12 for movement outwardly and upwardly to expose the motor. Secured on the body, as by means of bolts 13, is a catch member or frame 1 1 having a base flange 15 through Extending from the base flange are upwardly extendingv spaced web members 16 supporting the cross member or catch 17. The latter is formed on its upper side with a cannning surface 18 for a purpose presently to be explained,

and on its under side with a latch securing surface 19. One of the web members 16 carries a projecting portion 20 having an angular part 21 extending parallel with the inside ,of thehood, fora purpose which will later appear.

The latch portion of the device preferably comprises an open frame 22, Figure 4, having at its upper end a support or post 23 ried in the arms of the post. The lower end 9 of spindle 27 is formed with a piston-like head 29 on which slides a part or a cylinder 30 having at its upper end a head 231 threadedly secured thereto and sliding on the spindle. Coiled about the spindle within the cylinder 30 between the head 31 of the latter and the end of the spindle is a compression spring32' acting to urge the cylinder resiliently upward on the spindle away fromthe'catch. vTo guide the lower end of the cylinder 30 there is provided in sliding relation therewith a' guide or Collar 33-within a ring 34 carried by the lower end of frame 22 and secured therein as by means of a screw 35..

. operate latch hook a catch part'2l is alock erably of the key operated type, carrying at The lower end of the frame, as in the case of its upper end, is provided with a threaded shank 36 projecting externally through an opening in the hood to receive 'a nut 37 completing thesecure attachment of the frame on the hood. To reinforce the latter adjacent the. points of attachment of. the frame there is provided a stiffening plate 38 embracing at its ends and extending between the

shanks

24 and 36 of the frame.

The latch proper iscarried by the lower end of cylinder 30, comprising hook-like member 39, Figure 2, for engagement with the catch member 17, and it is to be noted that the hook of the latch is formed with an external camming surface 40 and an internal cammin'g surface 41 adapted to cowith the surface 18 of the catch so that whenthe. latch is lowered forengagementi with the catch it is thrown outwardly around the latter by the engagement of surfaces 40 and 181' Similarly for disengaging the latch the latter maybe first depressed so thatits surface 41-, cooperatin with surface 18 of the catch, throws the outwardly clear of the .catch so that it can then be swung outwardly andupwardly with the hood.

Carried by cylinder 30 and extending ex ternally through the body. Furthermore the location of the catch and latch within the hood provides for the application of the holding force of spring 32 to the hood in' such a manner as to pull the latter tightly in an inward direct-ion against the usual supporting surfaces on the body, thereby preventing any play or rattle of the parts. Fixed on and extending through the hoodin any suitable mann'er mechanism 44 prefits rear end an auxiliary latch 45 adapted to be swung by operation of the lock to and from a position inside the auxiliary catch 21. When latch 45 is moved to position opposite or inside catch 21, the hood portion is securely locked against unauthorized opening,

In closing the hood section the latter is moved, by grasping handle 43 which is pressed downwardly with the hood section the sup-porting ch p r serves' an opening 42 inthe hood is a handle 43Vpreferably in the form of a finger ring. l'

surfaces of the body downwardly, stressing spring body and holds it sehook outwardly clear of the catch so that a the hood may then be raised. The same also in combination with the locking means to prevent opening-of the hood except by use of a corresponding key.

In addition to the advantages of the con struction and arrangement already pointed out, the parts are located 'out of view within the hood so as to be afforded protection by the latter, and this arrangement preserves the desired simplicity of line in the structure and materiallyenhances its ap-' pearance;

I claim as my invention:
