CHAIN-CONNECTING DEVICE.
Application filed September 17, 1927.
This inventioi'l relates to a connecting device for chains and more particularly to the type of device used to connect the chains'provided in lifting snow plow such as is adapted to be attached to a motor truck.
The object of the present invention is the provision of a simple connecting device which will permit adjustments of the chains to enable the plow carried thereby to be adapted to various conditions.
In the drawing:
Fig. 1. is a front elevation of a truck carrying a plow and illustrating the use of the improved connecting device.
Fig. 2 is an enlarged front elevation of the connecting device.
Fig. 3 is a side elevation of the connecting device and as shown in Fig. 1, a snow plow 4 is attached to truck 2 in the usual manner and so that the plow t may be raised to an inoperative position. A frame 6, carried by the truck, supports a windlass for raising and lowering plow i by means of a chain 8. To the lower end of chain 8 there is connected a block 10 through which passes a chain 12, connected at its ends by springs 14 and 16 to the plow 4.
Block 10 is formed with an enlarged lower end 18, having an aperture 20 thereon, at the bottom of which is a curved groove 22, forming a raceway for chain 12. The groove 22 is of a size equal to the size of the chain links whereby the same will pass smoothly through the block. Above the raceway are pairs of aligning holes 24, extending through the walls of the block at the sides of aperture 20, the two holes forming each pair being in alignment transversely of the aperture. The two pairs of holesare spaced apart a distance approximately equal to the length of a link of the chain. A pin 26 is adapted to be inserted through the aligning holes of a pair and to be held in place therein by a cotter-pin 28. The pin 26 engages between the links of the chain, as shown in Fig. 2, thus preventing chain 12 from running through the block. Since the pairs of holes are spaced approximately the length of a link, it will be noted that an adjustment of chain 1.2 of approximately half a link length is provided.
The upper portion of block 10 is provided with a web 30, in which is formed a keyhole slot consisting of a circular enlarged hole 32, of a diameter greater than the width of a Serial No. 220,154.
link, and an extension slot 34, commuuicatino with hole 32 and of a width less than th t; width of a link and slightly greater than the thickness thereof. It will be seen that the chain 8 may freely pass through hole 32, but if a link thereof be inserted iii slot extension 34, the adjacentlinks, which are at an angle with. the link in slot 84, will, through contact with web 30, prevent running of the chain.
The above described construction provides a simple means for connecting two chains for ready adjustment, and is readily made as a slngle casting.
What I claim and desire to protect by Letters Patent is: 1. A connecting device for a chain compris- 1ng a block having an aperture therein and a raceway for guiding a chain passing through said aperture, and having a plurality of pairs of aligned holes spaced apart approximately the length of a link of said chain, and a pin adapted to be inserted through one pair of aligned holes to engage with the links of the chain to prevent movement of the chain through said aperture.
2. A connecting device for a chain comprising a block having a keyhole slot therein, said slot consisting of a hole through which a link may pass lengthwise in any position and an extension slot communicating with said hole, said extension slot being of such dimensions as to permit the passage of a link 1n one position thereof and prevent the pas sage of a succeeding link at an angle to the first link, and an aperture through which a second chain may be guided and means for preventing the movement of the second chain through the aperture.
3. A connecting device for a chain. comprising a block having an aperture therein and a raceway for guiding a chain passing through said aperture, said block having formed therein aligned holes on opposite sides of the raceway and spaced therefrom, and a pin adapted to enter said holes and be positioned thereby across the raceway to engage with the links ot the chain to prevent movement of the chain through said aperture.
In testimony of which invention, I have hereunto set my hand, at Kennett Square, Pennsylvania, on this 14th day of Septem ber, 1927.
