TRANSFER-CLAMP.

Specification of Letters Patent.

Application filed November 28, 1919.

To all 'whom t may concer/a:

Be it known that I, AUGUST NnLsoN, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Transfer- Clanips, of which the following is a specilication.

My invention relates to new and useful improvements in transfer clamps, and has for its object the provision of a transfer clamp which will be economic of manufacture, simple in structure, and highly etlicient in use.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to thev accompanying drawings forming a part of this specification, and in which,

Figure 1 is a front elevational view, showing my invention in mounted position,

Fig. 2 is a sectional view taken on substantially line 2-2 of Fig. 1, and

Fig. 3 is a sectional view taken on sub stantially line 3 3 of F ig. 1.

rlhe approved form of construction comprises a base or backing member 4, which is preferably constructed from metal or some hard wood. Projecting through the member 4 is a split key, having a loop 5 on one end. The opposite end comprises the members 5', which are bent over or clenched on the reverse or back side of the member 4. Projecting through the members 5 is a pin or shaft 6. In my invention a wire loop is provided, the upper end 7 of which is turned outwardly from the member 4, so that the loop itself engages the face of the backing member or the member secured to it with the two bights or points formed by the up-turned end of said loop, as at 7. The loop is also inclined outwardly from the backing member 4, as at 8, for the purpose of giving greater resiliency thereto. Formed at each end of the loop is a spiral coil 9, which is positioned upon the shaft or pin 6 intermediate the members 5. Each of the ends 10 of the wire which forms the coils 9 project downwardly and engage against the backing member 4. Secured to the face of the backing member is a rubber strip 11. As shown, the rubber strip 11 is the portion against which the wire loop engages.

Serial No. 341,117.

My invention is designed primarily for use by street car conductors for the purpose of retaining the transfers which they collect and those they giveout in the course of their duties. I am aware that devices have been constructed for the purpose of retaining'the transfers, but in my device, I have obvlated many of the difhculties of such devices. Primarily among these diiiiculties was the constant slipping of the transfers under the clamp, due to the fact that the backing sheet, against .which they were clamped was formed from wood or metal. In my invention, by using a rubber backing sheet, the material yields to the pressure of the clamp ,and thereby causes the transfers to seat in the slight recess formed in the contact member which is secured to the backing board by the pressure of the wire loop at certain points. It has been found from experiment that a shifting of transfers under the clamp is obviated by using a yieldable material, such as I have described. My invention is designed to be secured to the change containers, which are used by conductors and to this end a clip is provided, having a pair of semi-circular portions 12, which are joined by a central portion 13, which is provided with an orifice through which a boltV 14 is adapted to project. The bolt 14 projects through the member 4 and a coperating nut 15 is used to clamp the member 4 securely against the change container 16. As shown, the member 14 passes between the cylinders which contain the change. By this device, I have also provided a simple, efficient means of securing the transfer holder rigidly, in a convenient place for use.

'While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capa-ble of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of the construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A. device of the class described comprising a backing member; a rubbermember mounted on said backing member; a spring pressed member adapted to engage Patented N ov. 15,1921. l

against said rubber member; and means forv mounting said spring pressed member andV said rubber member Vupon said backing member, said means including split keys extend-y ing through'said rubber member and said backing member, substantially as` described.

2. A device of the class described com-V prising a backing member; an elastic member mounted on the face of saidbacking member; a wire loop having its upper and lower portions bent outwardly and its intermediate portions bent inwardly to engage against said elastic member; a spiral coil Y split keys for mounting said loop upon said backing member, substantially as described.

3. AY device of the class described comprising a backing member; an elastic membei" mounted upon said backing member; a

Wire loop adapted to engage against saidV elastic member; a spiral coil formed at each endof said wire loop, the ends thereof pro- Jecting downwardly and engaging against said backing member; a pin passing through Vsaid spiral coils; splitkeys engaging said pin andpassing through said elastic member and backingv member for mounting said loop uponsaid backing member; and means .for clamping said backing member to a change container, substantially as described. In testimony whereof have signed my name to this specification in the presence of Vtwo subscribing witnesses.
