Flaming Barriers (1924)

Patrick Malone, owner of the Malone Truck Company and inventor of a fire-fighting apparatus, seeks financial aid from local banker Joseph Pickens, who, hoping to control the manufacture of these machines, sends for a man to assist him. Sam Barton arrives. He is impressed with Malone's innovative fire truck, falls in love with his daughter, Jerry Malone, and refuses to enter into Pickens's scheme. During a visit of neighboring fire chiefs, a fire breaks out, and Sam and Jerry are able to prove the value of the apparatus by dousing a burning bridge, thereby saving the lives of hundreds of people. This act promotes the sale of a number of firetrucks and brings happiness to Malone, his daughter, and Sam.
